A cozy, veggie-packed vegetarian chili made with butternut squash, beans, corn, poblano peppers, and smoky fire-roasted tomatoes - inspired by the traditional “Three Sisters” pairing of squash, beans, and corn. Perfect for cool fall nights and even better the next day.

Instructions
 

Prep the vegetables.

  • Peel and seed the butternut squash, then cut into ½-inch cubes. Chop the onion and poblano peppers and mince the garlic.

Sauté the aromatics.

  • Heat olive oil in a large Dutch oven over medium heat. Add onion, poblanos, and garlic. Cook for about 5 minutes, stirring often, until softened and fragrant.

Build the chili.

  • Add butternut squash, kidney beans, tomatoes, vegetable broth, green chiles, corn, cumin, oregano, bay leaf, and about 1 teaspoon salt. Stir well.

Simmer.

  • Cover and simmer for 30 minutes, stirring occasionally. Remove the lid and continue simmering for another 10 minutes until slightly thickened and the squash is fork-tender.

Finish and serve.

  • Remove the bay leaf. Taste and adjust seasoning with additional salt and pepper if needed. Ladle into bowls and add your favorite toppings.

Serving Suggestions

I love serving this chili in oversized bowls with a pile of tortilla chips nearby for scooping and crunching directly into the chili. A little sour cream swirled on top cools the spice perfectly, and avocado slices make it feel extra cozy and satisfying.
And honestly? This chili might taste even better the next day.
