Ingredients Notes

• Ground beef: You can also use ground turkey or chicken.
• Yellow onion: Adds savory flavor.
• Garlic: Fresh or jarred both work.
• Taco seasoning: Use mild, spicy, or a homemade blend.
• Frozen corn: Canned or fresh corn works too. Trader Joe’s frozen corn is my favorite.
• Diced tomatoes with green chilies: Plain diced tomatoes work if you prefer less heat.
• Sour cream: Greek yogurt is a great swap for a lighter option.
• Doritos: Nacho Cheese is classic, but Cool Ranch, Spicy Nacho, or Sweet Chili all taste amazing.
• Mexican cheese blend: Cheddar cheese, Pepper Jack cheese, or Monterey Jack cheese are great alternatives.
• Black beans (optional): Pinto beans work too.
• Optional toppings: Green onions, lettuce, tomatoes, avocado, cilantro, salsa, or extra sour cream.

How to Make Dorito Casserole

1. Prep the pan: Preheat the oven to 350 degrees F and spray a 9×13 baking dish with nonstick spray.
2. Crush the chips: Finely crush two cups of Doritos for the casserole and lightly crush one cup for the topping.
   
3. Brown the meat: Cook ground beef and onion in a large skillet, draining any excess grease.
4. Add seasonings: Stir in garlic, taco seasoning, corn, tomatoes with green chilies, and the finely crushed Doritos. Add black beans if using.
5. Add the creamy layer: Remove from heat and mix in sour cream and two cups of cheese.
   
6. Bake the base: Spread the beef mixture into the prepared baking dish and bake in the preheated oven for 5 minutes.
   
7. Add topping: Sprinkle the remaining cheese and loosely crushed Doritos on top.
   
8. Bake again: Bake 5 more minutes until the cheese is melted.
9. Serve: Garnish with lettuce, tomatoes, avocado, green onions, or your favorite toppings if desired.

Make Ahead & Storage Instructions

• Store: Keep leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheat: Warm in the oven at 350 degrees to keep the chips crisp. Avoid reheating in the microwave if possible.
• Freeze: Freeze before or after baking for up to 3 months. Thaw in the fridge overnight before reheating.
• Make Ahead: Assemble up to 24 hours in advance, but wait to add the final Doritos and cheese until just before baking.
