Lentil Chili Slow Cooker Recipe

This slow cooker lentil chili is the kind of dish that makes your kitchen smell amazing all day. Think of it as the perfect union of tender lentils, vibrant vegetables, and a rich, smoky tomato base. It’s hearty enough to stand alone, but also plays well as a topping for baked potatoes, rice, or even cornbread.

• The low, slow heat allows lentils to absorb the spices fully.

• Flavors deepen and meld beautifully, creating a rich, layered taste that stovetop cooking sometimes misses.

Ingredient List

Here’s everything you’ll need to make this chili sing. I’ve included the amounts for a 6-8 serving batch.

• 1 cup dried brown or green lentils (rinsed and drained)
• 1 large onion, finely chopped
• 3 cloves garlic, minced
• 1 bell pepper (any color), diced
• 2 medium carrots, diced
• 2 stalks celery, diced
• 1 can (28 oz) diced tomatoes
• 2 cups vegetable broth (or water, but broth adds depth)
• 1 can (15 oz) black beans, drained and rinsed
• 1 can (15 oz) kidney beans, drained and rinsed
• 2 tablespoons tomato paste
• 2 teaspoons chili powder (adjust for heat)
• 1 teaspoon smoked paprika
• 1 teaspoon cumin

Instruction Guide

Follow these steps for chili perfection:

1. Prepare Your Vegetables And Lentils.

   • Chop onions, garlic, bell pepper, carrots, and celery. Rinse lentils thoroughly to remove any dust or debris.

2. Combine Ingredients In The Slow Cooker.

   • Add lentils, chopped vegetables, diced tomatoes, tomato paste, beans, and vegetable broth.

3. Add Spices.

   • Sprinkle in chili powder, smoked paprika, cumin, cayenne, oregano, salt, and pepper. Give everything a good stir to evenly distribute spices.

4. Cook Low And Slow.

   • Set the slow cooker to low for 6-8 hours or high for 3-4 hours. The longer it cooks, the more the flavors meld.

5. Adjust Seasoning And Thickness.

   • About 30 minutes before serving, taste for seasoning. Add extra salt, pepper, or chili powder if needed.
   • If chili is too thick, stir in a bit more broth or water. If too thin, remove the lid and cook on high for the last 30 minutes to reduce.

6. Serve And Enjoy.

   • Ladle into bowls and top with your favorite garnishes-fresh herbs, avocado, or a sprinkle of cheese transform it into a next-level dish.

Ingredient Swaps

Don’t panic if you’re missing an ingredient-this recipe is forgiving:

• Lentils: Red or yellow lentils work, but note they cook faster and become softer.
• Beans: Swap any canned beans or omit completely for a pure lentil chili.
• Vegetables: Zucchini, corn, or sweet potato can add extra texture and sweetness.
• Broth: Chicken or beef broth works if not keeping it vegetarian.
• Spices: Paprika can be substituted with chipotle powder for a smoky kick.

Helpful Tips

Make your chili foolproof with these insider tips:

FAQs

Can I Use Different Types Of Lentils In A Slow Cooker Chili?

Yes, you can use green, brown, or red lentils, but cooking times may vary slightly. Red lentils cook faster and tend to break down more, resulting in a thicker chili, while green or brown lentils hold their shape better and provide a firmer texture.

Do I Need To Soak Lentils Before Adding Them To The Slow Cooker?

No soaking is required for most lentils in a slow cooker chili. Lentils cook relatively quickly and evenly in the slow cooker. However, soaking can slightly reduce cooking time and may improve digestibility for some people.

Can I Make This Chili Vegan Or Vegetarian?

Absolutely. Lentil chili is naturally plant-based. You can enhance flavor with vegetable broth, canned tomatoes, beans, and a variety of vegetables like bell peppers, carrots, and zucchini. Avoid adding meat or meat-based broths to keep it vegan.

How Long Should I Cook Lentil Chili In A Slow Cooker?

Cooking times depend on the slow cooker setting. On low, cook for 6 to 8 hours; on high, cook for 3 to 4 hours. Stir occasionally if possible, and check the lentils for tenderness before serving.

Can I Freeze Leftover Lentil Chili?

Yes, lentil chili freezes well. Allow it to cool completely, then store in airtight containers or freezer bags for up to 3 months. Reheat on the stovetop or in the microwave, adding a little water or broth if needed to restore consistency.

How Can I Make The Chili Spicier Or Milder?

Adjust spice levels by adding chili powder, cayenne pepper, or fresh chili peppers for more heat, or reduce or omit these ingredients for a milder flavor. You can also balance spiciness with a touch of sugar, tomato paste, or dairy-free yogurt when serving.

Do I Need To Pre-cook Vegetables Before Adding Them To The Slow Cooker?

It is not necessary, but sautéing onions, garlic, and bell peppers beforehand can enhance flavor. Harder vegetables like carrots or celery can be added raw, as they will cook thoroughly in the slow cooker.

Can I Use Canned Lentils Instead Of Dried Lentils?

Yes, canned lentils can be used, but reduce the cooking time since they are already cooked. Add them in the last 30 minutes of cooking to prevent overcooking and maintain texture.

What Are Some Good Toppings For Lentil Chili?

Popular toppings include avocado slices, chopped fresh cilantro, vegan sour cream, shredded cheese (or dairy-free alternatives), sliced green onions, and crushed tortilla chips. Toppings can enhance flavor and texture without cooking.

Can I Make Lentil Chili In Advance And Reheat It Later?

Yes, lentil chili often tastes even better the next day as the flavors meld. Store in the refrigerator for up to 4 days, then reheat on the stovetop over low heat or in the microwave, stirring occasionally.
