Variations & Tips
For a spicier version, add a pinch of red pepper flakes or a diced jalapeƱo to the beef mixture. You can also substitute ground turkey or chicken for the beef for a lighter option. If you prefer a creamier texture, stir in a half cup of sour cream or cream cheese before baking. For a more colorful dish, consider adding chopped bell peppers or mushrooms to the skillet when cooking the onions.
