What is Slow Cooker Lentil Taco Chili?

Ingredients List for Slow Cooker Lentil Taco Chili
To make this delicious and wholesome chili, you’ll need the following ingredients:
- Lentils: 1 cup of dried brown or green lentils, rinsed. Lentils are the star of this dish, providing a meaty texture and plenty of plant-based protein.
- Black Beans: One can (15 ounces) of black beans, drained and rinsed. Black beans add creaminess and additional protein to the chili.
- Corn: One cup of frozen or canned corn, drained. Corn adds sweetness and texture to the chili.
- Diced Tomatoes: One can (15 ounces) of diced tomatoes with green chiles, undrained. This adds a tangy, slightly spicy base to the chili.
- Tomato Sauce: One can (15 ounces) of tomato sauce. This thickens the chili and adds rich tomato flavor.
- Vegetable Broth: Four cups of low-sodium vegetable broth. This serves as the liquid base, helping the lentils cook and the flavors meld together.
- Onion: One medium yellow onion, chopped. The onion adds sweetness and depth to the chili.
- Garlic: Four cloves of garlic, minced. Garlic brings a robust, savory flavor to the dish.
- Bell Peppers: Two bell peppers (any color), chopped. Bell peppers add a slight sweetness and color to the chili.
- Taco Seasoning: Two tablespoons of taco seasoning. This provides the bold, spicy taco flavor that sets this chili apart.
- Olive Oil: Two tablespoons of olive oil for sautéing the vegetables.
Substitutions and Variations
This recipe is versatile and can be easily adapted to suit your taste preferences or dietary needs:
- Lentils: You can use any type of lentils you prefer, but brown or green lentils hold up best during slow cooking. Red lentils will break down more and create a creamier texture.
- Beans: Substitute black beans with pinto beans, kidney beans, or even chickpeas for a different texture and flavor.
- Corn: If you prefer a different vegetable, try adding diced zucchini, carrots, or sweet potatoes.
- Spices: Adjust the spice level by adding more taco seasoning, a diced jalapeño, or a pinch of cayenne pepper. You can also use a homemade taco seasoning blend if you prefer.
- Dairy-Free: This recipe is naturally dairy-free, but if you want to add creaminess without dairy, consider stirring in some coconut milk or cashew cream before serving.
- Toppings: Customize your chili with a variety of toppings like avocado, cilantro, lime juice, shredded cheese (or dairy-free cheese), sour cream, or tortilla chips.

How to Cook Slow Cooker Lentil Taco Chili: A Step-by-Step Guide
Let’s take a closer look at some of the key steps to ensure your chili turns out perfect:
- Sautéing the Vegetables: Sautéing the onions, bell peppers, and garlic before adding them to the slow cooker enhances their flavors, adding depth to the chili. This step is optional but highly recommended.
- Layering the Ingredients: After sautéing the vegetables, layer the lentils, beans, corn, tomatoes, and tomato sauce in the slow cooker. Pour the broth over the top to ensure the lentils cook evenly.
- Slow Cooking: The slow cooker does most of the work, allowing the flavors to meld together while the lentils cook to tender perfection. Cooking on low for a longer time will yield the best flavor, but you can also cook on high if you’re short on time.
- Final Seasoning: After cooking, taste the chili and adjust the seasoning as needed. Lentils can absorb a lot of flavor, so don’t hesitate to add a bit more seasoning if necessary.
Common Mistakes to Avoid
Even with a simple recipe like this, there are a few common mistakes to watch out for:
- Skipping the Sauté: Don’t skip the step of sautéing the vegetables. It enhances their flavor and adds depth to the chili.
- Overcooking the Lentils: While lentils are generally forgiving, overcooking them can cause them to become mushy. Check the chili around the 6-hour mark (if cooking on low) to ensure the lentils are tender but not overcooked.
- Underseasoning: Lentils can absorb a lot of flavor, so be generous with the taco seasoning. Taste the chili before serving and adjust the seasoning as needed.
Serving and Presentation Tips
Even a hearty dish like chili can be elevated with thoughtful presentation:

- With Sides: Pair the chili with cornbread, tortilla chips, or a simple side salad to round out the meal.
