Spicy kick: Add diced jalapeños or a dash of hot sauce to the beef mixture.
Cheese swap: Use pepper jack or a blend of cheddar and mozzarella for different cheesy notes.
Gluten-free: Use gluten-free taco seasoning and substitute Doritos with a gluten-free chip alternative.

Large skillet: For browning and cooking the beef evenly.
9×13-inch baking dish: Perfect size for layering and baking the casserole.
Mixing spoon: To combine ingredients smoothly.
Measuring cups: For precise ingredient amounts.

Tips for Success

Brown the meat thoroughly and drain the fat to avoid greasiness.
Simmer the taco seasoning with water to let the flavors meld before adding other ingredients.
Don’t skip draining the canned corn and Rotel to prevent a soggy casserole.
Spread the Doritos evenly on both the bottom and top for balanced crunch.
Let the casserole rest 5 minutes after baking for easier slicing and serving.
