Vegetarian Slow Cooker Chili

This vegetarian chili is made by slow-cooking a medley of fresh vegetables, beans, and spices until tender and bursting with flavor. The dish develops a rich, hearty consistency with a vibrant tomato and lime base, and it has a thick, chunky appearance with a comforting aroma. The slow cooking process allows flavors to meld and deepen over time, creating a nourishing, pull-apart meal.

Equipment

  • Slow cooker
  • Chopping board

Ingredients
  

  • 2 cups diced tomatoes canned or fresh
  • 1 cup cooked black beans rinsed and drained
  • 1 cup cooked kidney beans rinsed and drained
  • 1 cup chopped bell peppers any color
  • 1 cup chopped zucchini about 1 medium zucchini
  • 1 medium onion diced

  • 2 teaspoons smoked paprika
  • 2 teaspoons ground cumin
  • 1/2 teaspoon chili powder
  • 1 dash lime juice freshly squeezed
  • 1 tablespoon olive oil

Instructions
 

  • Chop the onion, bell peppers, and zucchini into bite-sized pieces and mince the garlic. Measure out the canned diced tomatoes and rinse the beans to remove excess salt.

  • Heat the slow cooker and add olive oil. Once warm, sauté the diced onions and minced garlic directly in the slow cooker on the 'sauté' setting or in a pan until fragrant and translucent, about 3-4 minutes. This warms the kitchen with a savory aroma.

  • Add the chopped bell peppers and zucchini to the slow cooker, stirring to combine with the aromatics. Cook for another 2-3 minutes until they start to soften slightly.

  • Pour in the diced tomatoes, followed by the rinsed beans, smoked paprika, cumin, chili powder, and a pinch of salt if desired. Stir everything well to evenly distribute the spices and vegetables.

  • Cover the slow cooker with the lid and set it to low. Let the chili cook undisturbed for 4 to 6 hours, or until the vegetables are tender and the flavors are melded. The mixture will thicken and develop a hearty texture during this time.

  • Once cooked, stir in lime juice to brighten the flavors. If the chili has thickened too much, add a splash of vegetable broth to loosen it up slightly, stirring gently.

  • Taste and adjust seasoning as needed—adding more salt, lime, or spices to suit your preference. The chili should be thick, chunky, and fragrant with smoky, citrus notes.

Notes

For a spicier kick, add a dash of cayenne pepper or hot sauce. Leftovers reheat well and often taste even better the next day.
