For extra depth of flavor, consider sautéing the spices briefly with the garlic and onions before adding the meat. Use lean ground meat or plant-based crumbles for a lighter or vegetarian version. Add chipotle pepper or liquid smoke for smokier taste. Rinse canned beans to reduce sodium. Adjust heat with cayenne or jalapeños. Ensure gluten-free ingredients if needed. Leftover chili tastes better the next day and freezes well.
