Delight in a hearty vegan slow cooker chili bursting with vibrant flavor. Red lentils and sweet potatoes blend with crisp peppers, tomatoes, and black beans, while warming spices like cumin, chili, and smoked paprika create a rich, satisfying depth. A splash of lime adds brightness to this nourishing, soul-warming dish.

I love making this Lentil Sweet Potato Chili because its not only packed with good-for-you ingredients but it also warms you up after a long day. In the slow cooker, I mix in 1 cup dried red lentils, a large sweet potato diced into 1-inch cubes, and a large yellow onion diced nicely.
I also add 3 garlic cloves minced for extra flavor along with diced red and green bell peppers and chopped carrots for that added texture and nutrition. The diced tomatoes with their juices and a can of black beans bring a great balance of healthy proteins and fiber.
With vegetable broth, tomato paste, chili powder, ground cumin, smoked paprika, dried oregano and just a hint of cayenne pepper for a little heat, every spoonful sure delivers. I enjoy making this vegan crockpot recipe in the morning so its ready for me in the evening, and leftovers are even better the next day!

FAQ
Lentil Sweet Potato Chili Recipe Substitutions and Variations
- If you don’t have red lentils, you can use yellow split peas. They cook differently but still add a nice texture.
- Out of sweet potatoes? Try diced butternut squash instead. It’ll change the flavor slightly but works just fine.
- No black beans? Kidney or pinto beans can fill in nicely, even though they’ll give the chili a slightly different taste.
- If vegetable broth is scarce, mix water with a bouillon cube. It ain’t exactly the same but it’ll do the trick.
- Don’t have diced tomatoes? Crushed or stewed tomatoes may work too, just be aware the consistency will be a bit different.
Pro Tips
1. Try browning the onions and garlic in a pan before tossing them in the slow cooker – it really brings out a deeper flavor that you might not get if you just dump everything in the pot.
2. If you like your chili a bit thicker, mash some of the cooked sweet potatoes or lentils right near the end of cooking. That way you’ll get a creamier texture without losing all the chunks.
3. Remember to taste and adjust the seasoning after the slow cooking is done – slow cookers can sometimes mellow out the spices so a little extra salt or chili powder might be needed.
4. Let your chili sit for about 10 minutes after turning off the heat so all the flavors can really blend together and make your dish even more delicious.
