Ingredients for Slow Cooker Vegan Lentil and Sweet Potato Chili

Instructions

In a medium skillet over medium heat, warm the olive oil. Add the chopped onion and cook until softened and translucent, about 5 minutes.
Add the minced garlic and diced red bell pepper to the skillet, cooking for an additional 2 minutes until fragrant. Remove from heat.
In your slow cooker, combine the rinsed lentils, diced sweet potatoes, sautéed onion, garlic, and bell pepper mixture, diced tomatoes with their juice, tomato sauce, and vegetable broth.
Stir in chili powder, ground cumin, smoked paprika, dried oregano, cayenne pepper (if using), maple syrup, salt, and black pepper until all ingredients are evenly combined.
Cover and cook on LOW for 7 to 8 hours or on HIGH for 3 to 4 hours, until the lentils and sweet potatoes are tender and the chili has thickened.
About 15 minutes before serving, taste and adjust the seasoning as needed. Stir in fresh lime juice to brighten the flavors.
Serve hot, garnished with chopped cilantro if desired. This chili pairs wonderfully with cornbread or over cooked rice for a complete meal.
