Roast the Butternut Squash: Preheat your oven to 400°F (200°C). Toss the diced butternut squash with a drizzle of olive oil, salt, and pepper. Spread it out on a baking sheet and roast for 20-25 minutes until tender and slightly caramelized.
Brown the Meat: While the squash is roasting, heat a large pot over medium heat and add the olive oil. Add the ground turkey (or beef) and cook until browned, breaking it into crumbles with a spatula.
Sauté the Aromatics: Add the chopped onion, minced garlic, and diced bell pepper to the pot. Sauté for 4-5 minutes until softened and fragrant.
Add Spices & Liquids: Stir in the chili powder, cumin, paprika, and cayenne pepper (if using). Add the diced tomatoes, kidney beans, black beans, and broth. Bring the mixture to a gentle simmer.
Combine & Simmer: Once the butternut squash is roasted, stir it into the pot. Allow the chili to simmer for 20-30 minutes, stirring occasionally, until the flavors meld and the chili thickens.
Season & Serve: Taste the chili and adjust the seasoning with salt and pepper if needed. Ladle it into bowls and garnish with your favorite toppings.
