Ifisashi n'Ubwoko

Time15–20 minutes

Ingredients

Directions

Make the base

In a large pot, heat the vegetable oil over medium heat.
Add the chopped onion and minced garlic, and sauté until the onion is translucent and fragrant.
Add the sliced mushrooms to the pot and cook for a few minutes until they begin to soften.
Add the chopped spinach to the pot and stir well to combine with the mushrooms and onion mixture.

Add the peanut sauce

In a separate bowl, whisk together the peanut butter and water until smooth.
Pour the peanut sauce mixture into the pot.
Stir the ingredients together, ensuring that the peanut sauce coats the spinach and mushrooms evenly.
Season with salt and black pepper to taste.
Stir well to incorporate the seasoning.

Simmer and serve

Reduce the heat to low and let the stew simmer for about 15–20 minutes, allowing the flavors to meld together and the spinach to wilt.
Taste and adjust the seasoning if needed.
Remove from heat and transfer to a serving dish.
Serve hot with steamed rice or ugali.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Peanut butter: Creates a thick, creamy sauce that gives the stew body and a rich, nutty flavor.
Spinach: Provides the main bulk and leafy texture, wilting down as the stew simmers.
Mushrooms: Soften during cooking and add savory, earthy flavor and a tender texture.
Onion: Softens and turns sweet and fragrant, forming the flavor base of the stew.
