This sweet potato chili crockpot recipe is my go-to when I want a big pot of something hearty, smoky, and completely hands-off.

It thickens beautifully as it simmers, the sweet potatoes turning tender without falling apart, and the chipotle peppers bring a gentle, lingering heat that makes each bowl worth coming back to.

Why This Chili Works So Well

The slow cooker does the heavy lifting, breaking down the beans and sweet potatoes until the broth is rich and velvety. I love that the sweet potatoes soften to just the right tenderness without turning into mush.

A little chipotle in adobo adds deep smokiness that balances the sweetness of the potatoes, and a squeeze of lime at the end wakes everything up. It is the kind of chili that tastes even better the next day.

Ingredients

2 tbsp olive oil: for sautéing, or just swirl into the pot if skipping that step
1 large yellow onion, diced
3 cloves garlic, minced
2 medium sweet potatoes (about 1½ lbs total), peeled and cut into 1-inch chunks
1 can (15 oz) black beans, drained and rinsed
1 can (15 oz) kidney beans, drained and rinsed
1 can (15 oz) diced fire-roasted tomatoes, with their juices
2 tbsp tomato paste
1-2 chipotle peppers in adobo sauce, minced, plus 1 tbsp of the sauce: start with 1 pepper for mild heat
2 tbsp chili powder
1 tsp ground cumin
1 tsp smoked paprika
1 tsp kosher salt, plus more to taste
2 cups low-sodium vegetable broth
Juice of 1 lime
Toppings: avocado, cilantro, sour cream or yogurt, tortilla chips

Variations / Substitutions

Less heat: Swap the chipotles for an extra 1 tsp smoked paprika and a pinch of cayenne if you want a whisper of warmth.
Meaty version: Brown 1 lb ground turkey or beef with the onion, drain off excess fat, then proceed.
Beans: Any canned beans work here, pintos or cannellini are both great.
Sweet potato swap: Use butternut squash or even white potatoes cut the same size.
Thicker broth: Stir in 1 tbsp masa harina or cornmeal with the broth for a silky, stew-like texture.
If you enjoy hands-off bean dishes, try a white chicken chili in the slow cooker.

How to Make Slow Cooker Sweet Potato Chili

Step 1: Sauté the Aromatics

Heat the 2 tbsp olive oil in a skillet over medium heat. Add the diced onion and a pinch of salt and cook for about 5 minutes, until soft and translucent, then stir in the 3 cloves minced garlic, the 2 tbsp chili powder, 1 tsp cumin, and 1 tsp smoked paprika. Let it cook for 1 minute more until fragrant.

The kitchen will smell amazing at this point, and the spices will darken slightly. If you are in a rush, you can skip the sauté and add everything directly to the slow cooker, the flavor will still be good but a notch less deep.

Step 2: Combine Everything in the Slow Cooker

Scrape the onion mixture into a 6-quart slow cooker. Add the 2 medium sweet potatoes (cut into 1-inch chunks), the drained black beans and kidney beans, the can of fire-roasted tomatoes with their juices, 2 tbsp tomato paste, the minced chipotle peppers and 1 tbsp adobo sauce, 1 tsp salt, and 2 cups vegetable broth. Stir everything together until the tomato paste dissolves and the sweet potatoes are evenly coated.

You want the liquid to just barely peek above the solids, not swim. If it looks a little dry, add a splash more broth, but the sweet potatoes will release liquid as they cook.

Step 3: Slow Cook Until Tender

Cover the slow cooker and cook on low for 7 to 8 hours or on high for 4 to 5 hours. Try to avoid lifting the lid during the first few hours so the heat stays steady. After about 6 hours on low (or 3 on high), you can give it a gentle stir if you are around, though it is not required.

The chili is done when the sweet potatoes are fork-tender but still hold their shape and the broth has thickened and deepened in color. It will look glossy and smell smoky.

Step 4: Ladle and Top the Bowls

Stir in the juice of 1 lime, then taste and add more salt if it needs it. Ladle the chili into wide bowls and pile on your toppings, avocado slices, fresh cilantro, a spoonful of sour cream, and a handful of crushed tortilla chips.

The lime cuts through the richness and brightens the whole bowl. Serve right away while it is piping hot, with extra lime wedges on the side.

A Few Tips for the Best Slow Cooker Chili

Cut the sweet potatoes into generous 1-inch chunks so they stay intact after all those hours. Small cubes will turn to mush.
Start with 1 chipotle pepper and taste after cooking. You can always stir in a little more minced pepper or adobo sauce at the end if you want more heat.
If you find the chili a little loose for your liking, remove the lid and cook on high for the last 30 minutes to let some liquid evaporate.
For a subtle, mole-like depth, stir 1 tbsp unsweetened cocoa powder into the spice mix before adding the broth. It won’t taste like chocolate, just richer.
This chili freezes so well that I often make a double batch and stash half for busy nights.

Slow cooker times:

Setting	Time
Low	7 to 8 hours
High	4 to 5 hours

Storing Leftover Chili

Refrigerate: Cool the chili completely, then transfer to an airtight container. It will keep well for up to 5 days and the flavors are even better on day two.
Freeze: Portion into freezer-safe containers or bags and freeze for up to 3 months. Thaw overnight in the fridge.
Reheating: Warm gently in a pot on the stove over medium-low heat, stirring now and then, or microwave individual bowls. Add a splash of water or broth if it has thickened too much.

What to Serve With Slow Cooker Sweet Potato Chili

A slice of skillet cornbread is perfect for dipping and its slight sweetness plays off the smoky heat. A simple crunchy slaw with lime and cilantro adds a cool, fresh contrast. For a heartier meal, spoon the chili over steamed rice or stuff it into baked sweet potatoes.

Frequently Asked Questions

Can I double this recipe for a crowd?

Yes, this chili doubles easily. Use an 8-quart slow cooker or split it between two smaller ones and add an extra hour to the cook time on low.

Do I have to peel the sweet potatoes?

You can leave the peel on if you scrub them well. The texture will be a little more rustic and the peel adds extra fiber, just know the chili will look less uniform.

What if I don’t have a slow cooker?

Simmer everything in a large Dutch oven or heavy pot on the stovetop. Bring to a boil, then reduce the heat to low, cover, and cook for about 45 minutes, until the sweet potatoes are tender, stirring a couple of times.

Can I use dried beans instead of canned?

You can, but they need to be fully cooked before adding. Soak 1 cup mixed dried beans overnight, drain, and simmer in fresh water until tender before proceeding with the recipe.
