How to Make Black Bean Sweet Potato Soup

Here is exactly how we make this recipe: about 10 minutes of prep and roughly 30 minutes of cooking.

What you need: Large Pot.

1. In a large pot, heat the olive oil over medium heat.
2. Add the diced onion, red bell pepper, and jalapeno. Saute for 4 to 5 minutes or until the bell pepper is softened and the onion becomes translucent.
3. Stir in the finely chopped garlic and cook for another minute.
4. Add the ground cumin and smoked paprika and stir to combine.
5. Add the sweet potato cubes and black beans, then pour the vegetable stock and coconut milk. Stir well to combine and bring the mixture to a boil.
6. Reduce the heat and let the soup simmer for 15 to 20 minutes until the sweet potatoes are tender.
7. Next, add the fresh spinach to the pot and stir to combine. Place a lid on the pot and simmer for 1 to 2 minutes until the spinach wilts.
8. Adjust the seasoning to taste and serve hot with crusty bread, tortilla chips or cornbread.

That is the whole method. Nothing here needs special technique, just a little attention at the right moments.

Tips for the Best Black Bean Sweet Potato Soup

None of this is complicated, but these are the small habits that separate a good plate of this dish from a great one.

• Taste and adjust the salt at the end. Simmering concentrates everything, so season last.
• Simmer gently instead of boiling hard. A rolling boil can toughen the meat and cloud the broth.
• If it thickens too much as it sits, loosen it with a splash of broth when you reheat. If it thickens too much as it sits, loosen it with a splash of broth when you reheat.
• Read the steps once before you start. Knowing what is coming makes the whole thing calmer.
• Have everything measured and within reach before the heat goes on. Have everything measured and within reach before the heat goes on.

Taste as you go and adjust the seasoning at the end rather than the beginning. The recipe rewards a little attention right at the finish.

Variations and Add Ins

Black bean sweet potato soup takes changes well, so treat the recipe above as a starting point rather than a set of rules. These are the swaps we come back to most often.

• Change the shape. Anything with ridges or curves holds this sauce well.
• Add protein. Chicken, beef or shrimp turn it into a full dinner.
• Sneak in vegetables. Spinach, peas or broccoli stir in at the end with no fuss.
• Make it lighter. Half and half in place of cream keeps it silky with less richness.
• Change the herbs. Fresh parsley, basil or dill at the end each send it somewhere slightly different for no extra effort.
• Make it a bigger meal. Serve it over rice or with warm bread and it stretches to feed another person or two.

Change one thing at a time rather than three. That way you find out what you actually like in this one instead of guessing at the end.

How to Store and Reheat Black Bean Sweet Potato Soup

Leftovers keep in an airtight container in the refrigerator for up to three days. Pasta drinks up sauce as it sits, so add a splash of broth or cream when you reheat it and stir until it loosens up again.

If you are cooking ahead on purpose, prep the components and keep them separate until you are ready. It takes a few minutes off a busy evening and it holds its texture far better that way.
