Aromatics: Onion, Garlic, Extras

Onion + garlic = the foundation of flavor.

Sautéing these first unlocks a richer, layered one-pot sweet potato and black bean soup.

Tomatoes & Broth

Crushed or diced tomatoes add subtle tang and umami.
Vegetable or chicken-style broth forms the flavorful base.
More broth = thinner, soupier texture; less broth = thicker, chili-style bowl.

Ground cumin
Smoked paprika
Chili powder
Dried oregano
Coriander (optional)
Salt & black pepper

Optional boosters:

Chipotle in adobo or chipotle powder for deep smoke.
Red pepper flakes or jalapeño for extra heat.

Step-by-Step Sweet Potato and Black Bean Soup

Ingredients

2–3 medium sweet potatoes, peeled and diced
2 cans black beans, rinsed and drained (or ~3 cups cooked)
1 medium onion, finely chopped
3–4 cloves garlic, minced
1 can diced tomatoes (optional but recommended)
4–5 cups vegetable or light broth
2–3 tbsp olive oil (or use broth for oil-free sauté)
2 tsp ground cumin
1–2 tsp smoked paprika
1–2 tsp chili powder (adjust to taste)
1 tsp dried oregano
Salt & black pepper to taste
Juice of 1 lime
Fresh cilantro or green onion, for serving

Optional add-ins:

1 cup corn kernels
1 red bell pepper, diced
1 small jalapeño, minced
Chipotle in adobo or chipotle powder, to taste

Step 1 – Prep Everything

Dice sweet potatoes into even cubes (about 1–1.5 cm).
Rinse and drain black beans if using canned.
Chop onion, garlic, peppers, and measure spices.

Step 2 – Build the Aromatic Base

In a large pot or Dutch oven, warm olive oil over medium heat.
Add onion with a pinch of salt; cook until translucent.
Stir in garlic.
Sprinkle in cumin, smoked paprika, chili powder, and oregano.
Toast gently for 20–30 seconds to release aroma (don’t burn).

Step 3 – Add the Core Ingredients

Add diced sweet potatoes; stir to coat in spices.
Add black beans, tomatoes (if using), and enough broth to cover by about 2–3 cm.
Scrape the bottom of the pot to lift any browned bits—this builds deeper flavor.

Step 4 – Simmer to Tender Perfection

Bring to a gentle boil.
Reduce the heat to a steady simmer.
Cook 20–30 minutes, stirring occasionally, until:
- Sweet potatoes are soft when pierced.
- Flavors have melded into a rich, hearty sweet potato black bean soup.

Step 5 – Choose Your Texture

Chunky: Leave as is.
Half-blended: Use an immersion blender to blend a few quick pulses, or scoop out 1–2 cups, blend until smooth, and stir back in.
Silky: Blend fully (careful—cool slightly or blend in batches).

Step 6 – Finish & Balance

Right at the end:

Stir in lime juice.
Taste and adjust:
- More salt if flat
- More lime if it feels heavy
- More smoked paprika or cumin for warmth
- Tiny pinch of sugar or extra tomato if you’ve gone very smoky or spicy

Step 7 – Garnish & Serve

Top each bowl with:

Fresh cilantro or green onion
Slices of avocado
Crispy tortilla strips or crushed tortilla chips
A dollop of sour cream or a dairy-free alternative
Toasted pepitas or sunflower seeds
Extra lime wedges on the side

FAQs: Sweet Potato and Black Bean Soup

Can I use canned black beans instead of dried?

Yes. Add all ingredients (except lime and fresh herbs) to the slow cooker:

Cook on LOW for about 6–8 hours or HIGH for 3–4 hours.
