5-Star Review
This is an excellent recipe. The chili is absolutely delicious. I followed the recipe precisely, except I cooked on low for seven hours instead of six. This is because after six hours on low the lentils were still a little crunchy. After seven hours they were cooked perfectly though. Thank you so much for sharing this superb recipe. I will be cooking this again.

Ingredient Notes
Below is a quick overview of what you’ll need to make the recipe and any substitutions you can make. Use the recipe card with the full list of ingredients and measurements at the bottom of the post when you’re ready to make the recipe.
- Diced Tomatoes: Any brand of diced tomatoes. Fire-roasted tomatoes add extra depth and smoky flavour, though regular diced tomatoes work just as well.
- Onion: I usually use white or yellow onion but red onion is also fine.
- Chili Powder: Use a mild chili powder for a family-friendly chili or increase the spice with cayenne pepper or extra jalapeño.
- Bell Peppers: You can use green bell pepper, red bell pepper or any other colour. I like to mix and match different colors for variety.
- Red Lentils: Red lentils break down as they cook, creating a naturally thick, creamy chili without needing flour or cornstarch. They’re also an excellent source of plant-based protein and fibre.
- Vegetable Broth: Any store-bought or homemade broth, bouillon base or vegetable stock works. Start with 3 cups for a thicker chili. Add more broth during cooking if you prefer a thinner consistency.
- Tomato Paste: Tomato paste helps deepen the tomato flavor but if you’re in a pinch, you can substitute any tomato sauce.

How to Make Slow Cooker Red Lentil Chili
Step 1. Chop up the bell peppers, carrot, garlic, jalapeno and onion into small pieces and them to the crock pot. Chop everything roughly the same size so they cook evenly.
Step 2. Add the remaining ingredients and stir well to combine.
Step 3. Cover your crockpot and cook chili on high for 3 hours or low for 5-6 hours. Cooking times will vary depending on size and temperature of your slow cooker. The chili is done when the red lentils are soft, vegetables are tender and chili is thick.
Enjoy hot with your favorite toppings like sour cream, cheese or green onions.
What to Serve with Red Lentil Chili
This chili is filling on its own, but it’s also delicious served with:
- Cornbread
- Crusty bread
- Garlic toast
- Baked potatoes
- Basmati or brown rice

- Quinoa

Expert Tips
- Dice the vegetables into similar-sized pieces so they cook evenly.
- Start with 3 cups of broth, you can always add more near the end of cooking if needed.
- Red lentils naturally soften and partially dissolve, creating a thick, creamy texture.
- Let the chili rest for 10–15 minutes before serving to thicken even more.
- Double the recipe and freeze individual portions for easy lunches.
- You can cook the chili on high for 3 hours then turn it to low until you’re ready to eat.
Stovetop Instructions
To make lentil chili stovetop, sauté the onion, peppers, carrot and garlic for 5–6 minutes. Add the remaining ingredients and simmer for 25–30 minutes until the lentils are tender.
Frequently Asked Questions

How to Store Red Lentil Chili
This red lentil chili is perfect for meal prep because the flavors continue to develop as it sits, making leftovers even more delicious.
- Refrigerator: Let the chili cool completely, then transfer it to an airtight container. Store in the refrigerator for up to 5 days.
- Freezer: Portion the cooled chili into freezer-safe containers or bags and freeze for up to 3 months. Leave a little room at the top of the container to allow for expansion.
- To Reheat: Thaw frozen chili overnight in the refrigerator if possible. Reheat on the stovetop over medium heat or in the microwave until hot throughout. If the chili has thickened during storage, simply stir in a splash of vegetable broth or water until it reaches your desired consistency.

Sooo good
Thank you!
Loved this!
Hi – can you please add a note telling what SIZE slow cooker this recipe is using? I have a 3 quart one for a small household, and I need to know if I have to cut this recipe in half!
My slow cooker is 4 quarts. You can cut it in half if you like.
Wonderful recipe! I ran out of chili powder, so I used taco seasoning which worked out well, but next time I’ll use chili powder. These days I only have the energy for super easy slow cooker or pressure cooker recipes and this one will be on repeat!
Plus, the pictures for this recipe literally made me want to make it 🙂
