Most vegetarian chilis lean heavily on beans or peppers, but this recipe introduces a sweet twist with roasted sweet potatoes and hearty lentils. It’s a surprising depth of flavor that activates when you let it simmer all day in the slow cooker, filling your kitchen with cozy, caramelized aromas. This approach transforms simple ingredients into something both nostalgic and novel.
What’s more, I love how this chili adapts to busy schedules. Prep only takes a few minutes, then it’s hands-off until dinner. It’s perfect for those evenings when you crave comfort but want something vibrant and full of curious textures.
WHY I LOVE THIS RECIPE?
- It captures the essence of fall with its sweet and smoky notes.
- Each spoonful offers a velvety texture balanced by a slight crunch from fresh herbs.

- It’s endlessly customizable with pantry staples, making it a relief for last-minute dinners.

AVOID MY DISASTER (You’re Welcome)
- FORGOT the spices? The chili tasted dull—simply stir in fresh chili powder and cumin just before serving.
- DUMPED too much water? The chili lost its thick richness—add a handful of dried lentils or tomato paste to fix it.
- OVER‑TORCHED the onions? They turned bitter—rinse quickly with cold water and restart sautéing with less heat.
- FORGOT to peel the sweet potatoes? They stayed mushy—peel thinly and slice evenly to avoid breakdown.
QUICK FIXES THAT SAVE YOUR DAY
- When the chili smells burnt, splash in a splash of apple cider vinegar to neutralize the burn aroma.
- Patch a too-thin chili by stirring in a spoonful of tomato paste and simmering 10 more minutes.
- Shield over-seasoning with a splash of coconut milk—you’ll add creaminess without too much heat.
- When your pot runs low, substitute canned black beans if you’re out of kidney beans.
- When in doubt, add a pinch of smoked paprika—an instant smoky depth that crackles on your tongue.
This dish arrives just as the days grow shorter and the air turns crisper. It’s a comforting recipe that makes use of staples, yet surprises the palate. Whether you’re hosting a cozy family dinner or need a quick, satisfying meal after a busy day, this chili delivers.

Sweet Potato Lentil Chili
Equipment
- Baking sheet
- Large pot or Dutch oven
Ingredients
- 2 medium sweet potatoes peeled and cubed
- 1 cup dried lentils rinsed
- 1 tablespoon olive oil for roasting and sautéing
- 1 large yellow onion finely chopped
- 3 cloves garlic minced
- 1 can diced tomatoes 14 oz, with juice
- 4 cups vegetable broth
- 1 teaspoon ground cumin
- 1/2 teaspoon smoked paprika
- Salt and pepper to taste
Instructions
- Preheat your oven to 400°F (200°C). Spread the cubed sweet potatoes on a baking sheet, drizzling with 1 tablespoon of olive oil. Toss gently to coat, then roast for about 25-30 minutes until they’re tender and slightly caramelized around the edges.
- While the sweet potatoes are roasting, heat a tablespoon of olive oil in a large pot over medium heat. Add the finely chopped onion and cook for 5-7 minutes until translucent, filling your kitchen with a sweet aroma and the onions start to brown slightly.
- Add the minced garlic to the onions and cook for another minute until fragrant, stirring constantly to prevent burning. The mixture should smell savory and your kitchen will be filled with a fresh garlic scent.
- Pour in the diced tomatoes with their juice and stir well, breaking up some of the tomatoes with your spoon. Let this mixture simmer for 5 minutes, allowing the flavors to meld and the liquid to slightly reduce.
- Add the rinsed lentils, ground cumin, smoked paprika, salt, and pepper to the pot. Stir everything together, coating the lentils and onions evenly with the spices.
- Pour in the vegetable broth and bring the mixture to a gentle boil. Once boiling, reduce the heat to low, cover the pot, and let it simmer for about 25 minutes, stirring occasionally, until the lentils are tender and the chili has thickened.
- Check the roasted sweet potatoes; once they're caramelized and tender, add them directly into the chili. Gently stir to combine, allowing the flavors to meld for about 5 more minutes.
- Taste the chili and adjust the seasoning with more salt, pepper, or spices if needed. For a smoky boost, sprinkle in a pinch of smoked paprika, then give it a final stir.
- Serve the chili hot, garnished with fresh herbs if desired. Enjoy a hearty, textured dish bursting with sweet, smoky, and savory flavors.
