Ingredients

  • 2 cans (15 oz each) black beans, drained and rinsed
  • 1 can (15 oz) kidney beans, drained and rinsed
  • 1 can (15 oz) diced tomatoes, with juices
  • 1 cup frozen corn kernels
  • 1 large onion, diced
  • 3 cloves garlic, minced
  • 1 red bell pepper, diced
  • 1 green bell pepper, diced
  • 2 medium carrots, peeled and diced
  • 1 zucchini, diced
  • 2 tablespoons tomato paste
  • 2 cups vegetable broth
  • 2 teaspoons ground cumin
  • 1 tablespoon chili powder
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon cayenne pepper (optional, adjust for heat)
  • 1 teaspoon dried oregano
  • Salt and black pepper to taste
  • 2 tablespoons olive oil
  • Fresh cilantro for garnish (optional)
  • Juice of 1 lime (optional, for brightness)

Equipment

  • Slow cooker (4-6 quart size works best)
  • Cutting board and sharp knife for vegetables
  • Measuring spoons and cups
  • Wooden spoon or heatproof spatula for stirring
  • Can opener for canned goods
  • Ladle for serving

Instructions

  1. Prepare the vegetables: Dice the onion, red and green bell peppers, carrots, and zucchini. Mince the garlic cloves.
  2. Heat olive oil: In a skillet over medium heat, add the olive oil. Sauté the onion and garlic for 3-4 minutes until fragrant and slightly softened.
  3. Add bell peppers and carrots: Stir in the diced bell peppers and carrots, cooking for another 5 minutes to release their natural sweetness. This step enhances the flavor but can be skipped if short on time.
  4. Combine ingredients in slow cooker: Transfer the sautéed vegetables to the slow cooker. Add the diced tomatoes, tomato paste, black beans, kidney beans, corn, zucchini, vegetable broth, and all the spices — cumin, chili powder, smoked paprika, cayenne pepper (if using), and oregano.
  5. Season and stir: Add salt and pepper to taste. Give everything a good stir until well combined.
  6. Cook low and slow: Cover and cook on low for 6-8 hours, or on high for 3-4 hours. The longer it cooks, the more the flavors will develop.
  7. Final touches: Once done, taste and adjust seasoning if necessary. Stir in the lime juice for a bright, fresh finish.
  8. Serve and garnish: Ladle the chili into bowls and sprinkle with fresh cilantro if desired.

Tips & Variations

“To make this chili even heartier, consider adding chopped sweet potatoes or butternut squash for a natural sweetness and extra nutrients.”

For a vegan version, simply ensure your vegetable broth is vegan-friendly and skip any dairy toppings.

If you prefer a thicker chili, stir in a couple of tablespoons of masa harina or cornmeal during the last hour of cooking.

Spice lovers can amp up the heat with diced jalapeños or additional cayenne pepper. For a smoky depth without heat, add a teaspoon of chipotle powder.

Feel free to swap out black beans or kidney beans for pinto beans or cannellini beans based on what you have on hand.
