Ingredients

Servings 6
  • 2 (15 oz) cans black beans, drained and rinsed

  • 2 teaspoons smoked paprika
  • 1 ½ teaspoons ground cumin
  • 1 teaspoon chili powder

  • 1 tablespoon lime juice
  • Fresh cilantro, chopped (optional, for garnish)
  • Avocado slices (optional, for serving)

Instructions

  1. Set your slow cooker to the sauté setting, or heat olive oil in a skillet if your slow cooker lacks sauté function.
  2. Sauté the diced onion and red bell pepper for 3–4 minutes until softened and fragrant.
  3. Add minced garlic and cook for an additional minute, stirring frequently to prevent burning.
  4. Transfer sautéed vegetables to the slow cooker.

  6. Pour in vegetable broth and stir to combine all ingredients evenly.
  7. Add smoked paprika, ground cumin, chili powder, dried oregano, cayenne pepper (if using), salt, and black pepper. Stir well to distribute spices throughout the chili.
  8. Cover and cook on low for 6–7 hours or on high for 3–4 hours until flavors meld and the chili thickens to your desired consistency.
  9. About 15 minutes before serving, stir in lime juice and adjust seasoning with additional salt, pepper, or chili powder if needed.
  10. Serve hot, garnished with fresh chopped cilantro, avocado slices, and a dollop of dairy-free sour cream or vegan yogurt, if desired.
  11. Enjoy as a filling, family-friendly meal with warm corn tortillas, crusty gluten-free bread, or steamed rice for a complete wholesome dinner.

Frequently Asked Questions

Reader questions and answers for this recipe will appear here.

This recipe is naturally vegan, gluten-free, and dairy-free, but here are some ingredient swaps to customize based on availability or preference:

  • Black Beans: Substitute with pinto, kidney, or cannellini beans for varied textures.
  • Sweet Corn: Use fresh or canned corn, or swap with chopped zucchini for a lower-carb option.
  • Fire-Roasted Tomatoes: Regular diced tomatoes work well; add smoked paprika to mimic the smoky flavor.
  • Vegetable Broth: Use homemade or low-sodium broth; water can be used though flavor may be milder.
  • Olive Oil: Avocado or coconut oil provide alternatives with different flavor notes.
  • Spices: Adjust cayenne pepper to desired heat; chipotle powder adds smokiness. Modify chili powder to taste.
  • Lime Juice: Lemon juice works well as a substitute for fresh lime juice.

Pan Or Pot Required

This recipe is perfectly suited for a slow cooker, the ideal one-pot vessel for slow, even simmering that melds smoky spices with black beans and sweet corn into a rich, hearty chili.

To enhance flavor, a skillet or frying pan is needed to sauté aromatics like onion, bell pepper, and garlic before adding them to the slow cooker. If your slow cooker has a sauté function, use it directly; otherwise, a medium skillet with olive oil works best.

This combination of slow cooker and skillet makes this easy, budget-friendly, family-friendly one-pot meal simple to prepare, perfect for meal prep and busy weeknights.

Cookware Size Guidance

Use a 5 to 6-quart slow cooker for this recipe serving 6. This size accommodates all ingredients comfortably, ensuring even cooking without overflow while allowing the chili to thicken perfectly.

If your slow cooker is smaller (3 to 4 quarts), halve the recipe to prevent overcrowding and maintain proper cooking times and texture.

If no sauté setting is available on your slow cooker, use a medium (10 to 12-inch) skillet or sauté pan to soften the onion, bell pepper, and garlic without crowding, promoting better flavor development.

This cookware guidance ensures a hassle-free slow cooker experience perfect for family meals, meal prep, and minimal cleanup.

Cookware Swap Guidance

This chili shines as a Slow Cooker One-Pot meal with easy, hands-off cooking yielding flavorful vegan, gluten-free, and dairy-free results. If you lack a slow cooker, try these alternatives:

  • Instant Pot: Sauté aromatics first, then pressure cook on high for 20–25 minutes for a quicker yet flavorful chili.
  • Skillet + Oven: Sauté vegetables in a deep oven-safe skillet or Dutch oven, then cover and bake at 300°F for 1.5–2 hours to meld flavors.
  • Stovetop One-Pot: Use a heavy-bottomed pot to sauté and simmer with the lid on over low heat for about 1 hour, stirring occasionally, to develop depth.

For sautéing, a nonstick or stainless steel skillet is best to prevent burning. Avoid thin pans with uneven heating.

Slow cooking retains moisture and melds smoky, spicy flavors, delivering a nutritious, high-protein, vegan budget meal with minimal cleanup.

Leftovers Quality

This Slow Cooker Smoky Black Bean and Sweet Corn Chili makes delicious leftovers, retaining its rich flavor and hearty texture for 4–5 days refrigerated in an airtight container. Its vegan, gluten-free, and dairy-free nature makes reheating easy and quality consistent, perfect for meal prep and quick weeknight meals.

Freeze portions in airtight containers or resealable bags for up to 3 months. Thaw overnight in the fridge, then reheat gently on the stovetop or with microwave bursts, stirring to prevent drying out.

Refresh leftovers with a splash of vegetable broth or water if too thick and stir in fresh lime juice or cilantro to brighten the flavors. Avoid multiple reheating cycles to maintain taste and safety, ensuring your chili stays delicious and nourishing.
