This bold taco casserole layers seasoned ground beef, tangy salsa, creamy sour cream, and melted cheese for a harmonious blend of savory, creamy, and crispy textures. Perfect for busy weeknights or casual meals.
Use lean ground beef to reduce fat. Substitute avocado or Greek yogurt for sour cream for a dairy-free option. Leftovers can be refrigerated for 2-3 days.
