There’s a certain kind of magic that happens when you walk through the front door after a long, blustery commute and the air is thick with the scent of cumin, smoked paprika, and slowly simmering sweet potatoes. The first time I made this slow-cooker sweet-potato and black-bean chili, I had volunteered to host our monthly neighborhood soup-swap. I was racing between preschool pick-up and an evening Zoom call, and the only window I had to “cook” was the eight minutes it took me to dump everything into my ceramic insert the night before. The next afternoon, the sweet potatoes had turned velvety, the beans had soaked up all the smoky spices, and the entire house smelled like I’d been slaving over a stove for hours. My neighbor—self-proclaimed carnivore—texted me later that night: “I don’t even miss the meat.” That, my friends, is the quiet power of this chili. It’s weeknight-easy, meal-prep friendly, and somehow tastes even better reheated on day three when the flavors have had time to meld into something bordering on legendary.

Ingredients You'll Need

Sweet potatoes are the heart and soul of this chili, so pick firm, unblemished ones that feel heavy for their size. I like the deeper-orange Garnet or Jewel varieties—they’re sweeter and creamer after their long, slow bath. If you only have regular potatoes, swap away, but you’ll miss that subtle sweetness that balances the heat.

Black beans give the dish heft and complete plant-based protein. I cook mine from dried when I’m feeling virtuous (one cup dried equals about 2 ½ cups cooked), but two well-rinsed cans work beautifully on frantic Tuesdays. Look for low-sodium versions so you can control the salt later.

Fire-roasted tomatoes are my not-so-secret weapon. They bring a whisper of char that mimics hours of stovetop roasting. If your pantry only holds standard diced tomatoes, add ½ teaspoon of liquid smoke or a pinch of smoked salt to fake the effect.

Bell pepper adds body; I use red for sweetness, but orange or yellow work. Green peppers skew more bitter, so add a teaspoon of maple syrup if you go that route.

The spice line-up is forgiving: cumin and smoked paprika provide earthy depth, chili powder brings mild warmth, and a modest hit of chipotle powder delivers a smoky back-of-the-throat tingle. Adjust up or down—nobody’s judging.

Vegetable broth should be low-sodium and flavorful. Taste it first; if it’s flat, bump it up with 1 teaspoon of better-than-bouillon or a splash of soy sauce for umami.

Optional but lovely: a handful of frozen corn for pops of sweetness, a squeeze of lime right before serving, and a shower of fresh cilantro. If you’re a cilantro-phobe, swap in sliced green onions.

How to Make Slow Cooker Sweet Potato and Black Bean Chili

Prep the produce

Scrub sweet potatoes and peel if you prefer (I leave the skin on for extra fiber). Dice into ¾-inch cubes—any smaller and they’ll dissolve; larger stays pleasantly chunky. Finely dice onion and bell pepper; mince garlic. Rinse and drain beans if using canned.

Layer into slow cooker

Add sweet potatoes, black beans, tomatoes, onion, bell pepper, corn, garlic, spices, maple syrup, and 2 cups broth to a 6-quart slow cooker. Stir gently to combine without mashing the beans.

Check liquid level

Ingredients should be just barely submerged. Add remaining ½ cup broth if your slow cooker runs hot or you prefer soupier chili.

Cook low and slow

Cover and cook on LOW 6–7 hours or HIGH 3–4 hours, until sweet potatoes are fork-tender but still holding shape. Resist lifting the lid for the first 3 hours; steam escape extends cook time.

Taste and adjust

Stir in vinegar, salt, and pepper. Vinegar brightens all the earthy flavors—don’t skip it. Need more heat? Add ¼ tsp chipotle powder or a spoonful of adobo sauce.

Thicken (optional)

For a thicker texture, mash a cup of the chili against the side of the insert and stir back in. Prefer brothy? Leave as is.

Serve and garnish

Ladle into warm bowls. Top with avocado, cilantro, a squeeze of lime, and—if you’re feeling decadent—a sprinkle of feta or queso fresco. Offer hot sauce on the side for the heat-seekers.

Store or freeze

Cool completely, then refrigerate up to 4 days or freeze up to 3 months. Reheat gently with a splash of broth or water to loosen.

Expert Tips

Overnight trick

Assemble everything in the insert the night before, cover, and refrigerate. In the morning, set the cold insert into the base and add 30 minutes to cook time.

Speed option

Microwave diced sweet potatoes for 4 minutes before adding to the crock; cuts LOW cook time to 4 hours.

Texture tweak

Stir in ¼ cup refried beans during the last 30 minutes for instant silkiness without extra fat.

Make it cooler

Serve over cauliflower rice for a low-carb twist or stuff into baked sweet potatoes for a double-dose comfort meal.

Boost protein

Stir in 1 cup cooked quinoa or a drained can of pinto beans during the last hour for an extra 4 g protein per serving.

Color pop

Add ½ cup diced red cabbage just before serving; it stays crunchy and turns the dish into a visual feast.

Variations to Try

Pumpkin edition: Swap half the sweet potatoes for 1 cup canned pumpkin puree; it dissolves and creates a creamy base reminiscent of chili con carne.
Green chili style: Replace bell pepper with roasted Hatch chiles and add 1 tsp oregano. Top with crushed tortilla chips.
Peanut butter twist: Stir in 2 Tbsp natural peanut butter with the tomatoes for West-African richness; use lime juice liberally.
White bean remix: Sub black beans with great northern beans and add 1 tsp rosemary for a Tuscan vibe.
Breakfast chili: Reheat leftovers, create wells, and crack in eggs during the last 7 minutes on HIGH. Cover until eggs set.

Storage Tips

Refrigerate cooled chili in airtight glass containers for up to 4 days. The flavor actually peaks on day 2 when the spices have fully bloomed. For longer storage, portion into silicone muffin trays, freeze until solid, then pop out the pucks and store in zip-top bags—each puck is roughly ½ cup, making portion control effortless. Reheat on the stovetop over medium-low, thinning with broth or water as desired. Microwave works too: 60 seconds, stir, then 30-second bursts until steaming. If frozen, thaw overnight in the fridge or use the defrost setting before warming.

Frequently Asked Questions

Absolutely. Simmer everything in a heavy Dutch oven, partially covered, for 40–45 minutes over low heat, stirring occasionally. Add an extra cup of broth and check sweet-potato tenderness starting at 30 minutes.

Yes, provided your slow cooker is 7 quarts or larger. Keep cook time the same; simply stir more gently to prevent mashing the beans.

As written, it’s mild-to-medium thanks to chipotle powder. Omit it entirely for kids or add an extra ½ tsp for a slow burn.
