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
- Prep the pan: Preheat the oven to 350 degrees F and spray a 9×13 baking dish with nonstick spray.
- Crush the chips: Finely crush two cups of Doritos for the casserole and lightly crush one cup for the topping.

- Brown the meat: Cook ground beef and onion in a large skillet, draining any excess grease.
- Add seasonings: Stir in garlic, taco seasoning, corn, tomatoes with green chilies, and the finely crushed Doritos. Add black beans if using.
- Add the creamy layer: Remove from heat and mix in sour cream and two cups of cheese.

- Bake the base: Spread the beef mixture into the prepared baking dish and bake in the preheated oven for 5 minutes.

- Add topping: Sprinkle the remaining cheese and loosely crushed Doritos on top.

- Bake again: Bake 5 more minutes until the cheese is melted.
- 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.

This was delicious. We liked it with the black beans added. My only suggestion- if you know you’re going to have left overs, don’t cover the whole casserole in the Doritos on top. They will get soggy after sitting in the refrigerator and being reheated. Next time, I’ll only cover half and then put fresh chips on top reheated leftovers.
This was absolutely and excellent recipe and was not gummy or wet as someone else reported.
Made it for dinner tonight. Have a ton of beef we need to use up and came across this recipe. So good. Wasn’t expecting much but dang. Really good!
Forgot about sour cream but did have enchilada sauce mild so used that instead but still, so good!! Will use again. Thanks for putting this together!
Made this recipe as written except used nacho cheese Doritos. Delicious!
I made this for my Granddaughters 2nd Birthday Party yesterday. EVERYONE LOVED IT! It was a hair bit spicy I think for my Grandbaby, but she kept at it with both hands as her little eyes were on the verge of watering. Delicious dish and wonderful memory. Thank you so kindly!
Did I do something wrong? Chips are super soggy😩
My VERY picky 17 & 19 year olds loved this! Served it with refried beans and Mexican rice along with salsa and extra sour cream. Adding it to the family favorite list.
So glad it was a hit!
This is currently in my oven and I’m so excited to try it!!!!
Would you do anything different if you used Cheetos instead? My boyfriend loves Cheetos and I was wondering about trying it with those instead of the Doritos.
Could you make this and take it to a cookout
Hey! I’m looking to make this tomorrow but I don’t have sour cream, do you think cream cheese would be an okay substitution?
I honestly have never tried cream cheese. I don’t think it would be awful, but definitely cannot vouche for it!
Thanks for the quick reply! I’m gonna give it a whirl.. when in quarantine… 🙂
Would love to know how it works out! I mean, how bad could doritos, beef and cream cheese be?
