Navarin d'Agneau à l'Autocuiseur: Pressure-Cooked French Lamb Stew

In the countryside, we cook what the season gives us. Right now, it gives us this: beautiful lamb, ready for pressure cooked, asking only for simple accompaniment and careful hands. The garden teaches us. I learned to make this watching the light change through the kitchen window, hands in flour, nose full of herbs. That's the real recipe — the one that doesn't fit on a card. But I'll do my best to share what I know.

Instructions

Preparation (25 minutes)

Step 1: Prepare the Lamb (8 minutes) Remove the lamb from refrigeration and allow to come to room temperature for 10 minutes—this ensures more even browning. Pat the lamb completely dry using paper towels; moisture prevents caramelization and creates steam. Combine the flour, sea salt (approximately ½ teaspoon), and freshly ground black pepper in a shallow bowl. Working in batches, toss the lamb pieces in the flour mixture, shaking off any excess. The light coating creates a golden crust during browning and thickens the final sauce naturally. Discard remaining flour. Set the floured lamb on a clean plate. Step 2: Prepare the Aromatic Base (10 minutes) Mince the garlic finely. Slice shallots into ½-inch thick rounds (this keeps them more intact than dicing during pressure cooking). Combine the tomato paste with 2 tablespoons of the broth in a small bowl, stirring until smooth—this ensures the tomato paste disperses evenly rather than clumping. Set aside. Have the wine and remaining broth measured and ready. Step 3: Prepare the Vegetables (7 minutes) Cut carrots into 1½-inch chunks, peel and cut turnips or potatoes similarly, and peel the pearl onions (if using fresh onions, soak them in boiling water for 1 minute first, then slip off the skins—this makes peeling much easier). Measure out the fresh peas into a bowl. Set all vegetables aside in organized groups, as they'll be added at different stages during cooking. If using frozen peas, no preparation is needed.

Browning the Meat (8-10 minutes)

Step 4: Brown the Lamb (8-10 minutes) Heat 1 tablespoon of butter and 1 tablespoon of oil in a large heavy-bottomed Dutch oven or skillet over medium-high heat. When the fat is shimmering and nearly smoking, working in batches to avoid overcrowding, add approximately one-third of the lamb pieces. Don't stir them for 3-4 minutes—allowing them to develop a deep golden-brown crust on the first side is crucial for flavor development through the Maillard reaction. Flip each piece and brown the second side for another 3 minutes. Transfer the browned lamb to a plate. Repeat with the remaining lamb in two more batches, using the remaining 2 tablespoons of butter for the final batch. The goal is not to cook the lamb through but simply to create flavorful browning on all exterior surfaces. Set all browned lamb aside on a plate. Step 5: Sauté the Aromatics (3-4 minutes) In the same Dutch oven (don't clean it—the browned bits add flavor), reduce heat to medium. Add the shallots and cook for 2 minutes, stirring occasionally, until they soften slightly and begin to develop light browning. Add the minced garlic and cook for 30 seconds until fragrant but not browned—garlic burns easily and becomes bitter. Stir in the tomato paste mixture, coating the vegetables well, and cook for 1 minute while stirring constantly, allowing the tomato paste to caramelize slightly and integrate with the vegetables.

Pressure Cooking (20 minutes plus natural release)

Step 6: Build the Pressure Cooker Base (2-3 minutes) Pour the white wine into the Dutch oven and scrape up all the browned bits from the bottom with a wooden spoon—this deglazing adds tremendous depth of flavor. Allow the wine to reduce slightly over medium-high heat for 1 minute. Return the browned lamb to the pot, add the broth, vinegar, bay leaves, thyme, Herbes de Provence, black pepper, and Dijon mustard. Stir well to combine. Add the harder vegetables first: carrots, turnips or potatoes, and pearl onions. Do not add peas yet—they'll be added after pressure cooking. Step 7: Transfer to Pressure Cooker (1 minute) Transfer the entire mixture (or if using an Instant Pot as your pressure cooker, proceed directly) to your pressure cooker. Add additional broth if needed—the liquid should reach approximately ¾ up the sides of the meat and vegetables. Do not fill more than ⅔ full, as pressure cookers need headspace for the steam to function properly. Secure the pressure cooker lid and set to high pressure. Set the cooking time for 20 minutes. Allow the pressure cooker to build pressure naturally—this typically takes 5-8 minutes depending on your model. Step 8: Cook Under Pressure (20 minutes) Once the pressure cooker reaches full pressure (indicated by a pin or weight on top, or by your Instant Pot's display changing), the 20-minute timer begins. Do not open the pot during this time. The high-pressure steam environment breaks down the lamb's collagen into gelatin, making even tough cuts incredibly tender. The pressure also accelerates chemical reactions that develop flavor. Step 9: Natural Release (10-15 minutes) Once the 20 minutes of cooking time is complete, allow the pressure to release naturally. This means turning off the heat and letting the pressure cooker sit undisturbed for 10-15 minutes. The pressure will gradually decrease, and you'll see the valve drop or the pin on top lower. Do not use quick release for this dish—the rapid pressure change can toughen the meat. Natural release is gentler and allows the meat to relax and reabsorb cooking liquid. Step 10: Open and Assess (2 minutes) Carefully remove the pressure cooker lid, tilting it away from you to avoid steam burns. The lamb should be fork-tender, practically falling apart. If you prefer firmer lamb, 20 minutes is ideal; if you prefer more tender, another 5 minutes of pressure cooking is acceptable. The vegetables should be mostly tender but not mushy. If they seem undercooked, that's fine—they'll finish in the next step.

Finishing and Serving (8-10 minutes)

Step 11: Cook Remaining Vegetables (5-6 minutes) Using a slotted spoon, transfer the cooked lamb and initial vegetables to a large bowl, leaving the cooking liquid in the pressure cooker. Return the pressure cooker to stovetop over medium-high heat. Add the pearl onions if they weren't included earlier (if they were, skip this step). Bring the cooking liquid to a gentle boil and cook, uncovered, for 2 minutes. Add the peas and fresh herbs (parsley, tarragon, and mint if using), cooking for another 2-3 minutes until the peas are heated through and the flavors have integrated. If the cooking liquid seems thin and you prefer a thicker, more unctuous sauce, increase the heat to medium-high and simmer uncovered for 5-7 minutes to reduce and concentrate flavors. You should have approximately 1.5-2 cups of sauce with a silken consistency that coats a spoon. Step 12: Final Assembly (2-3 minutes) Return the lamb and cooked vegetables to the pressure cooker, gently stirring to combine. If using, stir in the heavy cream or crème fraîche. Taste the navarin and adjust seasoning with sea salt, black pepper, a squeeze of vinegar for brightness, or additional Dijon mustard for richness. The flavor should be simultaneously rich and balanced, with no single element overwhelming. Step 13: Plate and Serve Transfer the navarin to a large serving dish or individual bowls. Garnish with fresh parsley, tarragon, and a pinch of fleur de sel on each portion. The completed dish should show lamb, spring vegetables, and glossy sauce in every spoonful, with aromas of herbs and wine rising from the bowl.

Expert Tips

Lamb Selection and Quality: Choose lamb shoulder or stew meat with visible fat marbling—this fat keeps the meat moist during pressure cooking and contributes to sauce richness. Avoid extremely lean cuts like lamb loin, which become dry. Grass-fed lamb has more pronounced flavor than grain-fed, if available. The meat should smell fresh and clean, with a pink or bright red color.

The Browning Step is Non-Negotiable: Even though pressure cooking is faster, taking time to properly brown the lamb develops 80% of the finished dish's flavor. Rushing this step or skipping it results in a pale, flat-flavored stew that tastes "boiled" rather than "braised." Don't skip browning.

Natural Release is Essential: Quick-releasing pressure from a meat stew can toughen the meat. Allow natural release every time for optimal texture. Natural release takes 10-15 minutes but is completely passive—you simply wait. This time allows the meat to relax and reabsorb cooking liquid, resulting in more tender, flavorful lamb.

Vegetable Timing: The harder vegetables (carrots, turnips) go in with the lamb for pressure cooking. Delicate vegetables like peas are added after pressure cooking to prevent mushiness. If you use different vegetables (such as green beans or summer squash), adjust accordingly: add hardy vegetables with lamb, delicate vegetables after pressure cooking.

Pressure Cooker Models Vary: Instant Pots, traditional stovetop pressure cookers, and electric pressure cookers all have different intensities and release patterns. The first time you make this recipe, watch the stew more carefully and adjust cooking time by 2-3 minutes if needed based on results. Most pressure cookers require 18-22 minutes for lamb stew; this recipe specifies 20 minutes as the middle ground.

Make Ahead Advantage: This dish actually tastes better the next day as flavors mature and meld. Prepare it completely, cool to room temperature, refrigerate overnight, and gently reheat before serving. This also makes entertaining easier, as most work is done in advance.

Variations

With Pearl Onions and Root Vegetables Only (Vegetable-Forward Version): Use lamb shoulder cut into smaller 1-inch cubes instead of 1½-inch, reduce lamb quantity to 2 lbs, and increase vegetables to 5 lbs total (proportionally more carrots, turnips, pearl onions, and small potatoes). This creates a vegetable-centric version that's lighter yet still satisfying. The lamb provides flavor base rather than dominating the dish.

Navarin à la Provençale with Tomato and Olives: Increase tomato paste to 3 tablespoons, add 1 cup of diced tomatoes (fresh or canned), 1 cup of pitted black or Castelvetrano olives, 1 tablespoon of herbes de Provence (instead of ½ teaspoon), and ½ teaspoon of fennel seed. Replace white wine with red wine. This more Mediterranean version celebrates Southern French flavors and pairs beautifully with crusty bread for soaking sauce.

Spring Version with Young Vegetables Only: Use tender spring vegetables exclusively—baby carrots (halved lengthwise), baby turnips, spring peas, and fresh beans. Add 1 tablespoon of fresh mint and ½ teaspoon of fresh lemon zest in the final step. This lighter version celebrates seasonal availability and fresh herb brightness.

With Dried Apricots and Cinnamon: Add 1 cup of chopped dried apricots, ½ teaspoon of ground cinnamon, ¼ teaspoon of ground cloves, and 2 tablespoons of honey to the pressure cooker. This Moroccan-influenced variation adds sweet and spice that balances lamb's richness beautifully. Use red wine instead of white for deeper flavor.

Red Wine Version (Navarin à la Bourguignonne): Replace white wine with full-bodied red wine (Burgundy or Pinot Noir), reduce mustard to ½ teaspoon (red wine provides sufficient complexity), increase thyme to 1 tablespoon fresh or 1½ teaspoons dried, and add 1 teaspoon of crushed black peppercorns. This version is richer and more elegant, appropriate for special dinners.

Storage Instructions

Refrigerator Storage (4-5 days) Allow the navarin to cool completely to room temperature, transfer to airtight containers, and refrigerate for up to 5 days. The fat will solidify on top when cold, which helps preserve the dish and protect the lamb from oxidation. To reheat, preheat oven to 325°F and warm covered for 20-25 minutes until heated through, or gently reheat on the stovetop over medium-low heat, stirring occasionally. Add a splash of broth if the sauce has thickened excessively during storage. Freezer Storage (3 months) The navarin freezes beautifully because the fat content protects the meat. Cool completely, transfer to freezer-safe containers (leaving ½ inch headspace for expansion), label with date and contents, and freeze for up to 3 months. Thaw overnight in the refrigerator, then reheat using the oven or stovetop method above. The lamb becomes slightly more tender with freezing as ice crystals puncture cell walls—some chefs intentionally freeze and thaw before cooking to pre-tenderize tougher cuts. Reheating Best Practices Avoid microwave reheating, which creates uneven hot spots and toughens meat. Stovetop reheating over medium-low heat is ideal, covered, for 10-15 minutes while stirring occasionally. Oven reheating is even more gentle: cover the dish and warm at 300°F for 20-30 minutes. Add broth if the sauce has condensed during storage. The navarin actually improves with reheating as flavors continue to develop.

Serving Suggestions

Classic French Presentation Serve in shallow bowls or wide plates, ensuring each portion contains lamb, vegetables, and generous sauce. Accompany with crusty French bread for soaking sauce. A small crock of Dijon mustard on the table allows guests to adjust seasoning to preference. With Crushed Potatoes Serve alongside creamy mashed potatoes, crushed with butter and cream, which absorb the sauce beautifully. The starch complements the rich lamb and sauce without competing for attention. Over Polenta or Rice Creamy polenta or fluffy long-grain white rice (not brown rice, which competes with lamb's richness) makes an elegant base. Spoon the navarin and its sauce over the starch, allowing the liquid to seep into the grain. With Crusty Bread Only For a simple presentation, serve the navarin in deep bowls with crusty bread on the side for soaking sauce. This rustic presentation lets the food speak for itself and is perfect for intimate family meals. Wine Pairing Serve with the same wine used in cooking (dry white or red depending on version), or with a medium-bodied red like Côtes du Rhône or Burgundy. The wine's acidity cuts through lamb's richness and its tannins balance the dish's richness. French diners typically serve red wine with lamb dishes. Seasonal Sides Spring: green salad with Dijon vinaigrette. Summer: cold tomato salad with basil. Fall/Winter: roasted Brussels sprouts or braised red cabbage for color and textural contrast.

Frequently Asked Questions

Q: Can I use an Instant Pot for this recipe? A: Absolutely—that's what the recipe was designed for. Use the same ingredients and techniques, but set the Instant Pot to "Pressure Cook" or "Manual" for 20 minutes on high pressure. Allow full natural release. The results will be identical to a stovetop pressure cooker, and the Instant Pot's consistent temperature actually improves consistency across batches. Q: What if I don't have a pressure cooker? A: This recipe can be made in a traditional Dutch oven, though it requires longer cooking time. After browning the lamb and sautéing aromatics, transfer everything to a preheated 325°F oven in a covered Dutch oven and cook for 1.5 to 2 hours until lamb is fork-tender. You'll gain deeper, more complex flavors from the longer, gentler cooking, though it requires more time. The results are arguably even better than pressure cooking, though time investment is significantly higher. Q: Can I use lamb from different parts of the animal? A: Yes. Lamb shoulder (stew meat) is ideal for pressure cooking because it has good fat marbling and becomes very tender. Lamb neck is also excellent—it's less expensive and becomes incredibly silken when pressure cooked, though it requires removing a small central bone before serving. Avoid lamb loin or very lean cuts, which dry out. Any cut with collagen and fat marbling works well. Q: The vegetables are mushy—how do I prevent this? A: This happens when vegetables cook too long under pressure or when you're cooking vegetables that are too small. Use vegetables cut into 1½-inch pieces (not smaller), pressure cook for 20 minutes (not longer), and add delicate vegetables only after pressure cooking. Different pressure cookers have different intensities—if your first batch is too soft, reduce pressure cooking time by 2-3 minutes on your second attempt. Q: Why add peas after pressure cooking instead of before? A: Peas are delicate legumes that cook in just 3-4 minutes. If pressurized for 20 minutes, they become mushy and lose their bright color and fresh flavor. By adding them after pressure cooking, during the finishing phase, they reach perfect tenderness while retaining their visual appeal and delicate texture. This timing difference is true for all delicate vegetables.

Ingredient Substitution Guide

Navarin d'Agneau represents a classic French preparation, yet its success depends on ingredient quality and thoughtful substitution when specific items prove unavailable. The foundation begins with lamb—preferably from animals raised without growth hormones, fed on grass or quality grains, and processed carefully to avoid bruising. Lamb shoulder cut into stew meat provides ideal texture and fat marbling for pressure cooking. If lamb proves unavailable or prohibitively expensive, beef chuck or veal shoulder can substitute, though both require slightly adjusted cooking times and produce different flavor profiles. Avoid very lean cuts (sirloin or round), which dry out under pressure cooking's intense heat. Aromatics present fewer substitution challenges. The classic combination of onions, carrots, and celery provides aromatic support that's essential to the dish. While some regional variations use leeks instead of part of the onion component, the trinity of onion, carrot, and celery remains fundamental to French technique. Do not skip these vegetables or substitute them with garlic alone—they create the aromatic foundation that distinguishes proper navarin from mere stewed lamb. Red wine represents another essential component with limited substitution options. The recipe calls for dry red wine because acidity and tannins cut through lamb's richness while the alcohol burns off, leaving subtle flavor depth. White wine, while acceptable, creates a lighter, less traditional version. Dry red wine from any region works well—you need not use expensive Burgundy, though wines from the Rhône valley (Côtes du Rhône, Gigondas) create authentic results. If you abstain from alcohol or dislike wine's flavor, beef or lamb stock can replace half the wine quantity, though the resulting dish will taste less complex. The tomato paste component deserves consideration. Traditional recipes call for concentrated tomato paste for depth and umami contribution. If tomato paste is unavailable, crushed canned tomatoes can substitute (double the quantity to achieve equivalent concentration). Alternatively, some regional preparations eliminate tomato entirely, relying on wine, stock, and the vegetables' natural sugars for depth. The flavor profile shifts when tomato is absent, creating a different dish entirely—one that's arguably more delicate but less visually striking. Stock quality matters considerably in dishes that cook under pressure. The concentrated environment intensifies flavors—low-quality, high-sodium stock creates unpleasantly salty results. Quality stock from real ingredients tastes markedly superior. If forced to use bouillon cubes (which contain excessive salt and artificial flavors), use only half the suggested quantity and taste before seasoning further. Homemade stock, if available, creates the finest results, though quality commercial stock achieves acceptable results.
