 Why This Slow Cooker Sweet Potato Lentil Chili Works

This chili is a reliable choice because it balances sweetness from the sweet potatoes with savory depth from the spices and lentils.

Ingredients

  • 2 tablespoons olive oil
  • 1 large yellow onion, chopped
  • 2 bell peppers (any color), chopped
  • 3 cloves garlic, minced
  • 1 tablespoon chili powder
  • 2 teaspoons cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon cayenne pepper (optional, for heat)
  • 1 teaspoon salt, plus more to taste
  • 1/2 teaspoon black pepper, plus more to taste
  • 1 pound sweet potatoes, peeled and diced into 1/2-inch cubes (about 2-3 medium sweet potatoes)
  • 1 cup dried brown or green lentils, rinsed and picked over
  • 1 (28-ounce) can crushed tomatoes
  • 1 (15-ounce) can diced tomatoes, undrained
  • 4 cups vegetable broth
  • 1 (15-ounce) can kidney beans, rinsed and drained (or black beans)
  • 1 (15-ounce) can corn, drained (optional)

This collection of ingredients comes together to create a robust and comforting chili.

How to Make It

  • Sauté Aromatics: Heat the olive oil in a large skillet over medium heat. Add the chopped onion and bell peppers and cook, stirring occasionally, until softened, about 5-7 minutes.
  • Add Garlic and Spices: Stir in the minced garlic and cook for about 1 minute more until fragrant, being careful not to burn it.
  • Combine in Slow Cooker: Transfer the sautéed vegetable and spice mixture to your slow cooker.
  • Cook: Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, until the sweet potatoes are tender and the lentils are cooked through.
  • Adjust and Serve: Once everything is tender, stir the chili well.

This step-by-step process ensures a flavorful and well-textured chili every time.

 Nutrition at a Glance

  • Rich in Fiber: The lentils and sweet potatoes provide a substantial amount of dietary fiber, which is beneficial for digestion and satiety.
  • Good Source of Vitamin A: Sweet potatoes are an excellent source of Vitamin A, important for vision and immune function.
  • Plant-Based Protein: Lentils and beans contribute plant-based protein, making this chili a filling and satisfying meal.
  • Lower in Fat: Compared to traditional meat-based chilis, this vegetarian version is significantly lower in saturated fat.
  • Antioxidant-Rich: The colorful vegetables and spices offer a good dose of antioxidants.

These nutritional components make this chili a wholesome and nourishing option.

 How to Serve It

  • Toppings Galore: Offer a variety of toppings such as shredded cheddar cheese, sour cream or Greek yogurt, sliced avocado, chopped fresh cilantro, chopped red onion, or a squeeze of lime juice.
  • With Cornbread: This chili pairs wonderfully with a side of warm, homemade cornbread. The slight sweetness of the cornbread complements the savory chili, and the texture of a crumbly cornbread is a classic pairing with a hearty stew or chili.
  • Over Grains: Serve the chili over cooked quinoa, brown rice, or even a baked potato for a heartier meal.
  • As a Dip: Thicker chili can be served with tortilla chips or sturdy crackers for dipping.

Serving this chili with thoughtful accompaniments elevates the entire dining experience.

 Common Mistakes

  • Not Rinsing Lentils: Failing to rinse lentils can leave them with a slightly earthy taste and also remove any dust or debris.
  • Overcooking Sweet Potatoes: While the slow cooker is forgiving, sometimes overcooking can lead to mushy sweet potatoes.
  • Under-Seasoning: Chili needs robust seasoning to be flavorful.
  • Skipping Sautéing: While you can technically throw everything in raw, sautéing the onions, peppers, and garlic first builds a much deeper flavor base for the chili.
  • Using Too Much Liquid: If you prefer a very thick chili, start with closer to 3 cups of broth and add more only if needed during cooking.

Avoiding these common pitfalls will lead to a more successful and delicious batch of chili.

 Storage and Reheating

  • Refrigerator: Let the chili cool completely before storing it in an airtight container in the refrigerator for up to 4-5 days.
  • Freezer: This chili freezes exceptionally well. Portion it into freezer-safe containers or heavy-duty freezer bags for up to 3 months.
  • Reheating (Stovetop): Transfer the chili to a saucepan over medium heat. Stir occasionally until heated through.
  • Reheating (Microwave): Place a portion of chili in a microwave-safe bowl. Cover loosely and heat on medium power for 1-2 minutes, stirring halfway through, until hot.
  • Reheating (Slow Cooker): For larger quantities, you can reheat the chili directly in the slow cooker on the “warm” setting for 1-2 hours, stirring occasionally.

Proper storage and reheating ensure you can enjoy this delicious chili days after it’s made.

 Leftover Ideas

  • Chili Quesadillas: Spread a layer of leftover chili between two tortillas with cheese and pan-fry until golden and melty.
  • Chili Stuffed Sweet Potatoes: Reheat the chili and spoon it into halved and baked sweet potatoes for a hearty and flavorful meal.
  • Chili Nachos: Spoon the chili over a bed of tortilla chips, top with your favorite nacho toppings like cheese, jalapeños, and sour cream, then bake until the cheese is melted.
  • Chili Soup: Thin out the chili with a bit more vegetable broth, add some fresh spinach or kale, and serve as a lighter soup.

Repurposing leftovers can give this beloved dish a new life in your meal rotation.

Description

A hearty and flavorful Slow Cooker Sweet Potato Lentil Chili packed with wholesome ingredients. This easy recipe is perfect for weeknight dinners and is naturally vegetarian.


Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 large yellow onion, chopped
  • 2 bell peppers (any color), chopped
  • 3 cloves garlic, minced
  • 1 tablespoon chili powder
  • 2 teaspoons cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon cayenne pepper (optional, for heat)
  • 1 teaspoon salt, plus more to taste
  • 1/2 teaspoon black pepper, plus more to taste
  • 1 pound sweet potatoes, peeled and diced into 1/2-inch cubes (about 23 medium sweet potatoes)
  • 1 cup dried brown or green lentils, rinsed and picked over
  • 1 (28-ounce) can crushed tomatoes
  • 1 (15-ounce) can diced tomatoes, undrained
  • 4 cups vegetable broth
  • 1 (15-ounce) can kidney beans, rinsed and drained (or black beans)
  • 1 (15-ounce) can corn, drained (optional)

Instructions

  1. 1. Heat the olive oil in a large skillet over medium heat. Add the chopped onion and bell peppers and cook, stirring occasionally, until softened, about 5-7 minutes.
  2. 2. Stir in the minced garlic and cook for about 1 minute more until fragrant, being careful not to burn it. Add the chili powder, cumin, smoked paprika, oregano, cayenne pepper (if using), salt, and black pepper. Stir well to coat the vegetables and toast the spices for about 30 seconds.
  3. 3. Transfer the sautéed vegetable and spice mixture to your slow cooker. Add the diced sweet potatoes, rinsed lentils, crushed tomatoes, diced tomatoes (with their juice), vegetable broth, and rinsed kidney beans. If you are using corn, you can add it now, or wait and stir it in during the last hour of cooking for a fresher texture.
  4. 4. Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, until the sweet potatoes are tender and the lentils are cooked through. Stir the chili after about 2 hours to ensure everything is well combined, especially the lentils, which can sometimes settle at the bottom.
  5. 5. Once everything is tender, stir the chili well. Taste and adjust seasonings, adding more salt and pepper if needed. If you prefer a thicker chili, you can mash some of the sweet potatoes or lentils against the side of the slow cooker, or remove a cup of chili, blend it, and stir it back in.

Notes

Store any leftover chili in an airtight container in the refrigerator for up to 4-5 days, or freeze in freezer-safe containers for up to 3 months. Reheat on the stovetop, in the microwave, or in the slow cooker on warm.
