Best Lentil Sweet Potato Chili – Easy 50-Minute

I remember the first time I tried to make chili as a newlywed. I burned the beans, forgot the spices, and my husband politely ate it while making that 'I love you but this is weird' face. We laughed, ordered pizza, and I vowed to create a chili that was forgiving, flavor-packed, and actually easy.

This lentil and sweet potato chili is that recipe. It's the one I now make on repeat when I need a hug in a bowl. The sweet potatoes get all jammy and caramelized, the lentils soak up the smoky spices, and it all comes together in one pot with minimal fuss. Even my most carnivorous friends ask for seconds.

Whether you're a seasoned veggie lover or just trying to eat more plants, this chili is a winner. It's hearty enough to satisfy, healthy enough to feel good about, and the leftovers are even better the next day.

About the Ingredients

1 tablespoon olive oil

Use a good quality extra virgin olive oil for the best flavor. You can substitute with avocado oil or any neutral oil.

1 large yellow onion, diced

A sweet onion works too. If you're short on time, use a cup of frozen diced onions – no need to thaw.

3 cloves garlic, minced

Fresh garlic is ideal, but 1 teaspoon of garlic powder can work in a pinch.

2 medium sweet potatoes, peeled and cubed (about 4 cups)

Choose firm, heavy sweet potatoes. You can leave the skin on if you prefer extra fiber and texture.

1 red bell pepper, diced

Any color bell pepper works – use what you have. For a smoky twist, try a poblano pepper.

1 can (15 oz) fire-roasted diced tomatoes

Fire-roasted adds a deep, smoky flavor. Regular diced tomatoes are fine; add a pinch of smoked paprika if you have it.

1 cup (200g) dried green or brown lentils, rinsed

Green or brown lentils hold their shape well. Red lentils will get mushy – save them for soup.

3 cups (720ml) vegetable broth

Use low-sodium to control salt. You can also use water with a bouillon cube.

2 tablespoons chili powder

Adjust to your heat preference. For a spicier kick, add 1/2 teaspoon cayenne pepper.

1 teaspoon ground cumin

Toasting whole cumin seeds first adds extra depth – just crush them lightly before adding.

1 teaspoon smoked paprika

This gives the chili that 'cooked all day' flavor. Regular paprika works, but smoked is worth it.

Salt and black pepper, to taste

Start with 1/2 teaspoon salt, then adjust at the end – lentils absorb salt as they cook.

Tips & Tricks

Make it ahead

the flavors meld and improve overnight.

• Don't skip sautéing the onions and garlic – it builds a flavor base that can't be replicated by just throwing everything in.
• If you like a thicker chili, mash a few sweet potato cubes against the side of the pot before serving.
• Taste and adjust seasoning at the end – chili always needs a little more salt than you think.

Step-by-Step Instructions

1. Sauté Aromatics

Heat olive oil in a large pot or Dutch oven over medium heat (350°F/175°C). Add diced onion and cook for 5-7 minutes until translucent and fragrant, stirring occasionally. Add minced garlic and cook for 1 more minute until aromatic.

2. Toast Spices

Stir in chili powder, cumin, and smoked paprika. Cook for 30 seconds, stirring constantly, until the spices are fragrant and coat the onions. This releases their essential oils for a deeper flavor.

3. Add Vegetables

Add sweet potatoes and bell pepper. Stir to coat with the spice mixture. Cook for 3-4 minutes, letting the edges of the sweet potatoes start to brown slightly.

4. Add Liquids and Lentils

Pour in the fire-roasted tomatoes (with their juices), vegetable broth, and rinsed lentils. Stir everything together, scraping up any browned bits from the bottom of the pot.

5. Simmer the Chili

Bring the chili to a boil, then reduce heat to low (200°F/95°C). Cover and let it simmer gently for 30-35 minutes, or until the lentils are tender and the sweet potatoes are easily pierced with a fork. Stir occasionally to prevent sticking.

6. Check Doneness

The lentils should be soft but not mushy, and the sweet potatoes should be tender but still hold their shape. If the chili is too thick, add a splash of broth or water. If too thin, simmer uncovered for a few more minutes.

7. Season and Serve

Taste the chili and add salt and pepper as needed. Serve hot with your favorite toppings like avocado, cilantro, or a dollop of sour cream (or dairy-free yogurt).

Delicious Variations

• Add a can of black beans or kidney beans for extra protein and texture.
• Swap sweet potatoes for butternut squash or regular potatoes – adjust cooking time as needed.
• Make it smoky by adding a chipotle pepper in adobo sauce (minced) along with the spices.
