Background

Chili has long been a symbol of hearty American cooking — traditionally built around meat and beans. But over time, plant-based versions have gained popularity for their depth of flavor and nutritional benefits. Lentils, in particular, make a perfect stand-in for meat: they absorb spices beautifully, add protein and fiber, and create a thick, satisfying texture.
This vegan lentil chili borrows from Southwestern influences, featuring smoky chipotle powder, paprika, and cumin for that signature chili warmth. Meanwhile, roasted vegetables introduce caramelized sweetness and extra layers of flavor, creating a dish that feels as comforting as traditional chili but lighter and packed with plant-powered goodness.

Ingredients & Equipment

For the Chili:

1 yellow bell pepper, chopped
2 tablespoons tomato paste (30 g)
1 medium zucchini, diced
1 large sweet potato, peeled and cubed
4 cups vegetable broth (1 liter)
1 ½ cups dried brown or green lentils (300 g), rinsed
1 can (400 g / 14 oz) crushed tomatoes
2 teaspoons ground cumin
1 can (400 g / 14 oz) diced tomatoes
1 teaspoon smoked paprika
½ teaspoon chipotle powder (optional for extra heat)
1 teaspoon chili powder
Salt and black pepper, to taste
Juice of 1 lime

For Garnish (Optional):

Diced avocado
Lime wedges
Vegan sour cream or plain coconut yogurt

Equipment:

Large oven-safe pot or Dutch oven
Baking sheet
Wooden spoon
Ladle

Pro Tips:

Use brown or green lentils for the best texture — red lentils cook too quickly and become mushy.
Roasting the vegetables before adding them to the chili adds a smoky, caramelized depth of flavor.
If you prefer a thicker chili, simmer uncovered for an extra 10–15 minutes.

Step-by-Step Instructions

1. Roast the Vegetables (25–30 minutes)

Preheat your oven to 400°F (200°C). Toss the chopped bell peppers, zucchini, and sweet potato with 1 tablespoon olive oil, salt, and pepper. Spread evenly on a baking sheet and roast for 25–30 minutes, turning once halfway through. The vegetables should be slightly golden and tender when done.

2. Sauté the Aromatics (5 minutes)

In a large pot or Dutch oven, heat 1 tablespoon olive oil over medium heat. Add diced onion and cook for 3–4 minutes until translucent. Stir in the minced garlic and cook another minute, just until fragrant.

3. Build the Base (10 minutes)

Add the tomato paste, cumin, paprika, chili powder, and chipotle powder to the pot. Stir well to coat the onions and garlic, allowing the spices to bloom for about a minute. Add the crushed and diced tomatoes, stirring until everything is combined.

4. Simmer the Lentils (25–30 minutes)

Pour in the vegetable broth and lentils. Bring to a gentle boil, then reduce the heat to low and simmer uncovered for 25–30 minutes, or until the lentils are tender but not mushy. Stir occasionally and check the consistency — you can add a bit more broth if needed.

5. Combine and Finish (10 minutes)

Once the lentils are cooked, stir in the roasted vegetables. Let the chili simmer for another 10 minutes to allow the flavors to meld. Squeeze in fresh lime juice before serving to brighten the taste. Adjust seasoning with salt and pepper as needed.

Expert Tips & Troubleshooting

If your chili is too thick: Add a splash of vegetable broth or water to reach your desired consistency.
If your chili is too spicy: Stir in a little coconut milk or a spoonful of plain yogurt to mellow the heat.
For extra depth: Add a teaspoon of cocoa powder or a splash of balsamic vinegar to enrich the flavor.
Make it ahead: Chili tastes even better after sitting for a day as the flavors deepen overnight.

Variations & Customizations

Spicy Lentil Chili: Double the chili powder or add jalapeños for a bold kick.
Smoky BBQ Chili: Stir in 1 tablespoon of barbecue sauce for a subtle smoky sweetness.
Mediterranean Twist: Add chopped olives, sun-dried tomatoes, and a sprinkle of oregano.
Autumn Harvest Version: Swap zucchini for diced carrots and add roasted pumpkin cubes for a fall-inspired touch.

Serving & Presentation Ideas

Serve the chili hot in deep bowls, topped with your favorite garnishes. A dollop of vegan sour cream and a sprinkle of fresh cilantro or parsley add color and freshness. For texture, top with crushed tortilla chips, toasted pepitas, or crispy chickpeas. Pair it with crusty bread, quinoa, or rice for a heartier meal.
If serving for guests, garnish with lime wedges and set up a “topping bar” so everyone can personalize their bowl.

Storage & Make-Ahead Tips

Store leftovers in an airtight container in the refrigerator for up to 5 days. This chili reheats beautifully — just add a splash of broth when warming on the stovetop to loosen the texture.
To freeze, let the chili cool completely and transfer to freezer-safe containers. It will keep for up to 3 months. Thaw overnight in the fridge and reheat gently over medium heat until hot.

FAQ

Can I use canned lentils instead of dried?
Yes! If using canned lentils, drain and rinse them, then reduce the simmering time to about 15 minutes since they’re already cooked.

Can I make this chili in a slow cooker?
Absolutely. Add all ingredients except the lime juice to your slow cooker and cook on low for 6–7 hours or high for 3–4 hours. Stir in the lime juice at the end.

Can I add more protein?
You can mix in quinoa or add crumbled tofu for extra protein without changing the vegan profile.
