Cheesy Dorito Taco Casserole

Cheesy Dorito Taco Casserole combines the bold, comforting flavors of taco seasoned ground beef with the irresistible crunch of Nacho Cheese Doritos and gooey melted cheese. Layered with onions, Rotel tomatoes, and Mexicorn, this dish offers a perfect balance of savory, spicy, and sweet notes baked into a crowd pleasing casserole. It’s ideal for busy weeknights or casual get togethers when you want something satisfying without fuss.

I first made this for a game day gathering and it vanished before halftime. Now it’s one of those dishes everyone asks for repeatedly. The Doritos crust is always a hit and leftovers taste just as amazing the next day.

Ingredients

• Ground beef: Choose 80 percent lean for juicy flavor but with manageable grease
• Yellow onion: Adds sweetness and depth. Chop finely so it melts into the beef creating a rich base
• Minced garlic: Fresh garlic offers the best punch or use jarred if you are short on time
• Taco seasoning: Pick low sodium if watching salt and check it has no added sugars for cleaner taste
• Rotel: Diced tomatoes with green chilies. Adds tang and subtle heat. Use undrained for a saucy texture
• Mexicorn: This blend of corn and peppers brings vibrant color and a touch of sweet crunch. Look for crisp kernels in the can
• Taco blend cheese: Pre shredded melts quickly though shredding your own will give you stretchier, more melty cheese
• Nacho Cheese Doritos: Classic orange bag is best. Crush gently to keep a mix of larger and smaller pieces for texture contrast
• Optional toppings: Sour cream and Pico De Gallo bring coolness and freshness to brighten each bite

Instructions

Brown the Beef and Onion:

Cook the ground beef and onion in a large skillet over medium high heat. Stir often to break up the beef into small crumbles. Cook until no pink remains and the onion is translucent and soft. This slow caramelizing builds a juicy flavorful base for the casserole

Add Garlic and Drain:

Add the minced garlic and cook for about 30 seconds or until fragrant being careful not to burn. Immediately drain off any excess fat from the skillet. This keeps the casserole from becoming greasy and balances the flavors

Season and Mix:

Sprinkle in the taco seasoning. Stir to coat the beef evenly. Then add the Rotel tomatoes with their juices and the drained Mexicorn. Mix well and heat through. The juices from the Rotel help keep the mixture moist so the casserole won’t be dry

Layer the Casserole:

Spread half of the meat mixture evenly in a seven by eleven inch casserole dish. Top with half the taco blend cheese then a layer of crushed Doritos. Spread gently to ensure each bite gets that signature crunch. Repeat these layers with the remaining meat, cheese, and Doritos. Press down lightly so the layers settle evenly without compressing too much

Bake Until Bubbly:

Place the uncovered casserole in a 350 degree Fahrenheit oven. Bake for 15 to 20 minutes or until the cheese melts fully and the Doritos on top crisp up. You will notice golden bubbly cheese edges and the smell will be irresistible

Finish and Serve:

Let the casserole rest about five minutes after removing it from the oven. This helps the layers set so it serves neatly. Then top generously with sour cream and fresh Pico De Gallo. These additions add a cooling brightness that balances rich cheesy and spicy flavors

Whenever I crush the Doritos I always use a freezer bag and get my youngest to help. This makes the process fun and gives the chips just the right texture. Every time we wonder if extra cheese is really needed but somehow it always makes its way into the casserole. I especially love how the Mexicorn and Rotel combine to keep the dish colorful and moist instead of dry

Storage Tips

Refrigerate leftovers tightly covered with foil or plastic wrap for up to three days. To store longer portion into airtight containers and freeze for up to two months. To reheat, warm covered in the oven or microwave. For a crunchy top, briefly toast under the broiler after reheating

Ingredient Substitutions

Ground turkey or chicken can be swapped for beef to lighten the dish without losing flavor. Black beans and extra corn can replace meat for a vegetarian version. If you cannot find Mexicorn canned corn with some diced red peppers works well. Mild diced tomatoes with a bit of chopped green chili stand in for Rotel if you want less heat

Serving Suggestions

This casserole stands well on its own but pairs wonderfully with a crisp green salad adding freshness. A toppings bar with shredded lettuce, guacamole, and extra cheese lets everyone customize their plate. Hot sauce or pickled jalapenos offer a nice kick for those who love spice

This Cheesy Dorito Taco Casserole is a simple satisfying crowd pleaser that reheats well. It’s perfect for nights when you want big flavor without fuss.
