Ingredients for adasi soup

West African pantry staples meet tender lamb and toasted spices for this soul-warming stew.

The lamb shoulder is the heart of this dish—bone-in cuts deliver the richest flavor, but boneless works in a pinch. Look for well-marbled pieces at Whole Foods or your local butcher; the Costco lamb shoulder is a budget-friendly favorite. Palm oil gives Adasi its signature deep red hue—red palm oil is essential, not the clear refined kind. If you can't find it, substitute 2 tbsp tomato paste for color, though the flavor won't be identical. Barley should be pearled (not whole grain) for consistent cooking—Bob's Red Mill has a great option in the baking aisle.

Groundnuts (peanut butter) add the signature richness—unsweetened, natural peanut butter works best, but any smooth peanut butter will do. No dried shrimp? Substitute 1/4 cup cooked shrimp or omit entirely. For the toasted spices, heat the groundnuts oil in a dry pan until fragrant (about 2 minutes) before adding cloves, nutmeg, and cinnamon—this step is non-negotiable for that signature crunch. Fresh ginger and garlic? Always fresh—dried loses its punch. The leafy greens can be whatever you have on hand (spinach, kale, or even frozen chopped greens work), but bitterleaf adds that authentic West African bite if you can find it.

This soup tastes even better the next day as flavors meld—double the batch if you're feeding a crowd. Store in the fridge for 4-5 days or freeze portions for up to 3 months. For serving, keep the toasted spice blend separate until ready to eat—it loses crunch when soaked in broth. Pair with fufu or jollof rice for the full experience, but it's equally delicious with crusty bread or even over mashed potatoes for a fusion twist.

Step-by-step instructions for Adasi soup

Here's how to craft this West African classic with rich lamb, nutty barley, and that signature toasted spice crunch.

Heat the 0.5 cup palm oil in a large Dutch oven over medium-high heat until shimmering. Add the 2 lb lamb shoulder cut into 1.5-inch pieces, working in batches if needed to avoid crowding. Sear for 4-5 minutes per side until the meat develops a deep mahogany crust and releases easily from the pan.

Here's the thing—this initial sear builds the foundation of your soup's complexity. The caramelized exterior traps flavors while the bone-in pieces ensure maximum gelatin release during simmering. Remove the lamb to a plate and set aside, leaving all the rendered oil in the pot.

In the same Dutch oven, reduce heat to medium and add 2 tablespoons groundnut oil. Add the 0.5 teaspoon ground cloves, 0.5 teaspoon ground nutmeg, and 0.25 teaspoon ground cinnamon, stirring constantly for 1-2 minutes until the spices release their essential oils and become deeply fragrant.

This is where the magic happens—the toasted spices create that signature crunch we can't live without. Watch carefully as they darken slightly—just until you can smell that warm, earthy aroma filling your kitchen. Immediately add the 6 minced garlic cloves and 2 tablespoons grated fresh ginger, cooking for another 30 seconds until fragrant but not browned.

Lower heat to medium-low and stir in the 0.25 cup groundnut butter, allowing it to melt completely and blend with the spices. Add the 1 cup rinsed pearled barley and toast for 1 minute, stirring constantly to coat each grain with the nutty butter mixture.

The groundnut butter adds both richness and body to the soup. This step ensures your barley absorbs those toasted spice flavors before we add any liquid. Pour in 4 cups vegetable stock and bring to a gentle simmer, then add the 0.25 cup rinsed dried shrimp and 1.5 teaspoons salt. Return the seared lamb to the pot.

Cover the pot and simmer gently for 1 hour 15 minutes until the lamb is fork-tender and falls apart easily. You'll know it's ready when a knife slides in and out with minimal resistance—this typically happens when the internal temperature reaches 195°F at the thickest part.

Here's my pro tip: If the soup reduces too much, add water ½ cup at a time to maintain the proper consistency. The lamb should be so tender it practically melts in your mouth, with just enough resistance to hold its shape when served. This long simmer also allows the barley to soften properly while absorbing all those rich flavors.

Stir in the 2 cups chopped dried leafy greens and simmer uncovered for 5-7 minutes until they wilt completely and the liquid reduces slightly. Taste and adjust seasoning with additional salt or 0.5 teaspoon black pepper as needed—this soup should be rich but balanced.

For that authentic Adasi finish, I like to stir in a spoonful of the toasted spice blend at the end to emphasize that signature crunch. Serve immediately with crusty bread or jollof rice to soak up every last drop of this flavorful stew.

Pro cooking tips for great adasi soup

Toast Spices Properly

Never skip toasting your spices—they're the secret to that signature crunch in Adasi soup. Heat the 2 tablespoons groundnut oil in your Dutch oven over medium heat until it shimmers, then add the 0.5 teaspoon ground cloves, 0.5 teaspoon nutmeg, and 0.25 teaspoon cinnamon. Stir constantly for 1-2 minutes until the spices darken slightly and release their aromatic oils. This step should take your breath away with that warm, earthy aroma—it's what transforms this from ordinary to extraordinary. 🌶️

Sear Lamb in Batches

Crowding the pan is the fastest way to steam instead of sear your lamb. Work in 2 batches if needed, using 0.5 cup palm oil over medium-high heat for that perfect mahogany crust. The key is patience—4-5 minutes per side ensures deep flavor development. I've learned the hard way that rushed searing leads to bland soup. Remove the lamb only when it releases easily from the pan, leaving all that precious rendered oil behind. 🥩

Simmer at Low Heat

Adasi soup demands gentle simmering to tenderize the lamb without turning the barley mushy. Maintain a gentle bubble (not a rolling boil) for 1 hour 15 minutes½ cup water if needed. The internal temperature should reach 195°F at the thickest part. Too much heat = tough meat. Too little = undercooked lamb. I use a meat thermometer to avoid guesswork every time. ⏰

Leafy Greens Timing

Add your 2 cups dried leafy greens only in the final 5-7 minutes of cooking. This prevents them from turning to mush and ensures they wilt just enough to release their earthy flavors. I like to use spinach or bitterleaf—whatever's available. If using frozen greens, thaw and drain them first to avoid watering down the soup. The greens should be tender but still hold their shape when served. 🌿

Spice Blend Storage

Make extra toasted spice blend—it's perfect for future batches or to sprinkle on rice dishes. Store it in an airtight container in a cool, dark place for up to 2 months. The crunch diminishes over time, but the flavor remains potent. I keep a small jar on my spice rack for quick access. This pre-made blend saves 15 minutes of prep time each time you make Adasi soup. ✨

Lamb Resting Secret

After simmering, let the lamb rest in the soup for 10 minutes off the heat before serving. This allows the juices to redistribute, keeping each bite tender and flavorful. I've found that serving it immediately can make the meat slightly tougher. The resting time also lets all those beautiful aromatics meld together one final time before you dig in. Trust me, this small step makes a world of difference. 💫
