Why this recipe works

Editorial notes before you cook

There's something magical about how peanut butter transforms into the silky backbone of this beloved West African stew. The scotch bonnet pepper—kept whole so you can fish it out—adds just enough gentle heat to wake up all those earthy, comforting flavors. Sweet potatoes melt into creamy bites while collard greens keep their character, creating the kind of bowl that makes everyone at the table slow down and savor. It's forgiving, nourishing, and fills your house with the most incredible smell.

The goal here is not just heat. It is contrast, pacing, and texture: enough richness to feel satisfying, enough brightness to keep the plate moving, and enough chile character that the spice actually tastes like something.

Method

How to cook it

Use the step navigator to move around, or stay in cook mode and work top to bottom.

  1. 1

    Step 1 of 4

    Build your aromatic foundation

    Start by heating the oil in a large, heavy-bottomed pot—this prevents sticking and gives you even heat. Add your diced onion and let it cook gently, stirring now and then, until it becomes translucent and starts smelling sweet. This takes about 5 minutes and creates the flavor base for everything that follows.

  2. 2

    Step 2 of 4

    Layer in the aromatics and tomatoes

    Stir in the garlic and ginger, giving them just a minute to release their fragrance—any longer and they might burn. Add the canned tomatoes with all their juices and the tomato paste, stirring to combine. Let this bubble gently for a few minutes so the tomato paste loses that raw edge and everything melds together.

  3. 3

    Step 3 of 4

    Create the peanut base

    Here's where the magic happens—whisk that peanut butter with a cup of broth in a separate bowl until it's completely smooth. No shortcuts here; lumpy peanut butter will give you a lumpy stew. Pour this creamy mixture into your pot along with the rest of the broth. Add the whole scotch bonnet (keeping it intact is key for gentle heat), coriander, and paprika.

  4. 4

    Step 4 of 4

    Simmer until everything's tender

    Add those cubed sweet potatoes and bring everything to a gentle simmer. Let them cook for about 15 minutes—they should be fork-tender and starting to break down just a bit, which helps thicken the stew naturally. Stir in the chopped collard greens and cook until they wilt and turn that beautiful bright green, about 5-8 minutes more. They should be tender but still have some body.

Troubleshooting

Tips that matter

  • Natural peanut butter without added sugar gives you the most authentic, rich flavor
  • That whole scotch bonnet pepper is your heat control—remove it early for milder stew, leave it longer for more warmth
  • The perfect consistency coats the back of a spoon but isn't thick like paste

Substitutions and variations

Remix without losing the point

Swap in kale, spinach, or Swiss chard if collard greens aren't available
Butternut squash works beautifully in place of sweet potatoes
Coconut oil brings similar richness if you can't find palm oil
For heat lovers, add a whole habanero alongside the scotch bonnet
Stir in a pinch of cayenne during the last few minutes if you want a gentle kick

Storage and leftovers

Plan ahead and reheat well

Make ahead

Like many stews, this one tastes even better the next day as all those flavors have time to get cozy together. Make it up to 3 days ahead, though you might want to add the collard greens fresh when reheating if you prefer them bright green.

Storage

Keep it covered in the fridge for up to 5 days. Don't worry when it thickens up significantly in the cold—that's just the peanut butter and sweet potatoes doing their thing.

Reheat

Warm it gently on the stovetop over low heat, stirring frequently so nothing sticks. Add a splash of broth or water if it seems too thick. Skip the microwave if you can—the oils might separate and look a bit odd.

Serve it like you mean it

Finish, pair, and plate

  • Ladle over fluffy jasmine rice or nutty brown rice
  • Serve alongside warm flatbread or crusty bread perfect for dipping
  • Top with chopped roasted peanuts and fresh cilantro for extra texture and color

FAQ

The repeat questions

Can I make this without the scotch bonnet pepper?

Absolutely, though you'll miss some of that authentic West African flavor. A whole jalapeño works as a milder substitute, or just add a tiny pinch of cayenne at the very end for a gentle warmth.

Why did my stew turn out too thick?

Those sweet potatoes are natural thickeners—they break down and make the stew hearty and rich. Just thin it out with more vegetable broth or water until it feels right to you.

Can I use crunchy peanut butter instead?

Smooth gives you that silky traditional texture, but crunchy definitely works if that's what's in your pantry. You'll get a more rustic texture and might need to whisk a bit more enthusiastically to get it incorporated.
