Prepare Your Ingredients: Dice the onions, bell pepper, garlic, and any optional veggies. Measure out the spices.
Brown the Venison: In a large pot or Dutch oven, heat olive oil over medium heat. Add the ground venison, season with salt and pepper, and brown until fully cooked.
Sauté the Aromatics: Push the venison to one side of the pot. Add the diced onions, bell pepper, and garlic. Cook until softened, about 5 minutes.
Add Spices: Stir in chili powder, cumin, and paprika. Let the spices toast for about a minute to release their flavor.
Build the Chili: Add diced tomatoes (with juices), drained beans, and broth. Stir everything together, bringing it to a simmer.
Simmer: Reduce heat to low, cover partially, and let simmer for 30-45 minutes, stirring occasionally. Adjust seasoning to taste.
Optional Thickening: If you prefer a thicker chili, mash some of the beans or stir in masa harina during the last 15 minutes of cooking.
Serve: Garnish with toppings like shredded cheese, sour cream, diced onions, jalapeños, or fresh cilantro.
