Vegetarian Butternut Squash Chili with Black Beans

Heat oil in a large heavy-bottomed soup pot or Dutch oven over medium-high heat. Add garlic, onion and salt; cook, stirring often, until starting to brown, 4 to 6 minutes. Add chili powder, cumin, cinnamon and chipotle and stir to coat. Cook, stirring often, until the spices are fragrant but not scorched.

Add broth and squash; increase heat to high and bring to a simmer, stirring occasionally. Cover, reduce heat to medium-low and simmer until the squash is tender, 18 to 20 minutes.

Stir in black beans, crushed tomatoes and diced tomatoes. Increase heat to medium-high and bring to a simmer, stirring often.

Reduce heat to medium-low and simmer, uncovered and stirring often, until the flavors have melded and the chili is thickened, 5 to 7 minutes. Serve the chili topped with a dollop of yogurt and sprinkled with cilantro and red onion, if desired.
