This slow cooker lamb and sweet potato mafé brings the deep, savory comfort of traditional West African peanut stew into your home kitchen with minimal effort required. By letting the slow cooker do the heavy lifting, you achieve tender, falling-apart lamb and perfectly soft sweet potatoes coated in a rich, velvety peanut and tomato sauce that is sure to become a staple in your meal rotation.
Mafé is a beloved dish known for its incredible depth of flavor, primarily driven by the combination of creamy peanut butter and tangy tomato paste. This version simplifies the process by using a slow cooker, which allows the tough connective tissues in the lamb shoulder to break down slowly over several hours.
The result is a deeply flavorful, comforting meal that balances the earthiness of root vegetables with the nutty, savory notes of the sauce. It is an ideal recipe for those who appreciate deep, complex flavors but prefer a hands-off approach to cooking.
Ingredients
Main Ingredients
- 2 lb lamb shoulder, cut into 1-inch cubes
- 2 medium sweet potatoes, peeled and diced
- 1 large yellow onion, thinly sliced
Sauce
- 2 cups peanut tomato broth
Why this recipe works
The slow cooker method is ideal for lamb shoulder, a cut that benefits significantly from long, low-temperature cooking. The consistent, gentle heat transforms the meat, making it exceptionally tender while allowing the sweet potatoes to absorb the savory sauce.
This process ensures that the flavors meld together perfectly, creating a cohesive stew that tastes even better as the ingredients simmer slowly in their own juices.
The peanut and tomato base creates a unique flavor profile that is both rich and satisfying. The acidity of the tomatoes cuts through the natural richness of the lamb, while the peanut butter provides a creamy body to the sauce. This combination is a classic for a reason, providing a balanced, hearty meal that feels luxurious yet remains simple enough for a standard weeknight dinner.
Notes and substitutions
Lamb shoulder is the preferred cut for this dish due to its balanced fat content, which keeps the meat moist during the extended cooking time.
If you cannot find lamb shoulder, beef chuck roast is a suitable alternative as it also contains the connective tissue needed for slow cooking. Ensure you cut the meat into uniform pieces so they cook at the same rate, resulting in a consistent texture throughout.
The peanut tomato broth is the heart of this dish. Use a high-quality, natural peanut butter if possible, as it will emulsify better into the tomato base. The equipment needed is minimal; a standard slow cooker is sufficient.
Be mindful of the size of your sweet potato cubes; cutting them too small may cause them to disintegrate into the sauce, while pieces that are too large may remain slightly firm.
