This instant pot African lamb stew uses the West African method of building a stew on a blended tomato-pepper base, fresh tomatoes, red bell pepper, scotch bonnet and garlic blended smooth, then cooked down with aromatics and spices before the lamb is pressure cooked until completely tender. What would take two hours on the stovetop takes 25 minutes under pressure.

Lamb shoulder is the right cut, the connective tissue converts to rich gelatin under pressure, thickening the sauce naturally. The result is a deep, savoury, slightly spiced stew that tastes like it has been going since morning.

Ingredients

1kg lamb shoulder, bone-in or boneless, cut into 5cm chunks, shoulder over leg. Leg is leaner and dries out under pressure. Shoulder has the right fat and collagen ratio for a pressure-cooked stew, it becomes completely tender and enriches the sauce as it cooks.
3 medium tomatoes, quartered
1 large red bell pepper, roughly chopped
1–2 scotch bonnet or habanero peppers, 1 for moderate heat, 2 for serious heat. Deseed for a milder result. This is the heat foundation of West African cooking, do not substitute with chili flakes which give a completely different flavour.
1 large onion, half goes in the blender with the tomatoes; half is diced and sautéed first
5 cloves garlic, minced
1 tablespoon fresh ginger, grated
3 tablespoons neutral oil
2 tablespoons tomato paste, cooked out in the pot before the blended mixture goes in
200ml beef or lamb stock, also needed to deglaze and prevent BURN error
1 teaspoon curry powder, the West African household curry powder used in Nigerian and Ghanaian cooking, not South Asian curry powder, though that substitutes well
1 teaspoon ground cumin
1 teaspoon sweet paprika
½ teaspoon ground coriander
½ teaspoon ground cinnamon
1 teaspoon bouillon powder or 1 stock cube, Maggi or Knorr cubes are standard in West African cooking. Adds umami depth.
Salt and black pepper to taste
2 medium carrots, cut into chunks, added before pressure cooking
Fresh parsley or cilantro, to finish

Step by step

Make the blended pepper base. Add the tomatoes, red bell pepper, scotch bonnet(s) and half the onion (roughly chopped) to a blender. Blend until completely smooth. Use minimal water, the mixture should be thick, not watery. Set aside. This blended base is the foundation of West African stew cooking. It gives the finished dish a depth and colour that diced tomatoes simply don’t produce. Blend it smooth, visible chunks will not soften properly under pressure.
Season and brown the lamb. Pat the lamb pieces completely dry with paper towels, wet meat steams rather than browns. Season generously with salt and pepper. Set the Instant Pot to SAUTÉ (high). Add the oil. When shimmering, brown the lamb in two batches, do not crowd the pot. Sear 3–4 minutes per side until deeply golden. Remove and set aside. Browning the lamb on the Sauté setting before pressure cooking is optional but builds significant flavour. The Maillard reaction on the lamb surfaces adds a depth of flavour that pressure cooking alone cannot create.
Sauté aromatics and spices. Add the diced onion to the pot with the remaining oil. Sauté 3–4 minutes until softened. Add the garlic and ginger, stir 1 minute. Add the tomato paste and cook, stirring, for 2 minutes until it darkens. Add all the dry spices and bouillon and stir for 30 seconds until fragrant.
Add blended base and deglaze, critical step. Pour the blended tomato-pepper mixture into the pot. Stir and cook on Sauté for 3–4 minutes, scraping up every browned bit from the bottom of the pot. Pour in the stock. Stir again and check the bottom is completely clean, no stuck residue. This prevents the BURN error during pressure cooking. The BURN error triggers when the Instant Pot detects food stuck to the bottom during pressurisation. It cannot be fixed once cooking starts. The deglaze step, liquid plus scraping is the only prevention. Do not rush it.
Pressure cook. Return the browned lamb to the pot. Add the carrot chunks. Stir to combine. Cancel Sauté. Secure the lid and set the valve to SEALING. Pressure cook on HIGH for 25 minutes.
Natural release, then finish. When the timer beeps, allow natural pressure release for 10–15 minutes, do not quick-release immediately. After 10–15 minutes, carefully switch the valve to VENTING to release any remaining pressure. Open the lid away from you. The lamb should be completely tender and pulling apart. Set back to SAUTÉ. Simmer uncovered for 5–8 minutes until the sauce thickens to your preference. Taste and adjust salt. Natural release allows the meat fibres to relax gradually, quick-releasing a pressurised meat stew can tighten the protein slightly, making the meat less tender. 10–15 minutes natural release is the standard for lamb and beef stews.
Serve. Scatter fresh parsley or cilantro over the top. Serve hot over white rice, with fufu, or with flatbread.

Claire’s note
Two things that reliably cause problems with this recipe in the Instant Pot. First: the BURN error. It happens when the blended tomato base sits on the bottom of the pot without enough liquid or with residue from the browning stage still stuck there. The fix is thorough deglazing, pour in the stock, scrape the bottom of the pot with a wooden spoon until completely clean, then proceed.
Second: do not skip browning the lamb, even though it’s extra steps and extra washing up. The flavour difference between browned and unbrowned lamb in a pressure cooker stew is significant and worth the 10 minutes.

Stovetop and slow cooker alternatives

Stovetop: Follow the same steps through the deglaze. Return the lamb, add stock, bring to a boil then reduce to a low simmer. Cover and cook 1.5–2 hours until completely tender, checking occasionally and adding water if the stew gets too thick.

Slow cooker: Complete the browning and sautéing in a separate pan, then transfer everything to the slow cooker. Cook on LOW for 7–8 hours or HIGH for 4–5 hours. Remove the lid for the final 30 minutes to thicken the sauce.
