Ingredients
- Ground beef: Two pounds packs in lots of flavor and protein Always choose beef with a bit of fat for the juiciest results
- Yellow onion: The half onion brings sweetness to balance spicy notes Look for firm heavy onions with shiny skins
- Minced garlic: Just a tablespoon gives depth and warmth Fresh garlic cloves are best but jarred will do in a pinch
- Taco seasoning: A whole packet gives that classic taco spot flavor Go for your favorite blend or try spicy for a kick
- Rotel: One can undrained brings tomatoes and green chilies adding tang and mild heat Double-check the label for your preferred spice level
- Mexicorn: This can has sweet corn and peppers for color and crunch Check for vibrant kernels without too much liquid
- Taco blend cheese: Two cups shredded makes every bite melty and bold Pre-shredded saves time but hand-shredded melts extra creamy
- Nacho Cheese Doritos: The soul of this casserole Use a 9.25 ounce bag crushed up so each layer gets plenty of chip
- Optional toppings: Sour cream cools things down Pico de gallo adds fresh brightness Pick ripe tomatoes for the best pico
Step-by-Step Instructions
- Brown the Beef and Onion:
- Cook the beef and diced onion together in a large skillet over medium-high heat Stir and break apart the beef until it is cooked through and fully browned Make sure no pink remains as this builds a savory base for the casserole
- Add Garlic and Drain:
- Once the meat is browned add the minced garlic Stir it in and cook for about forty seconds until fragrant Turn off the heat and carefully drain any excess grease from the skillet for a less greasy casserole
- Mix in Flavors:
- Return the skillet to the stove and add the taco seasoning followed by the whole can of Rotel and the drained Mexicorn Use a spoon to combine everything thoroughly so every bite is flavorful
- Layer in the Casserole Dish:
- In a seven by eleven inch casserole dish spread half the meat mixture over the bottom Add a layer of shredded cheese followed by a layer of crushed Doritos Press gently to keep everything even and compact
- Repeat Layers:
- Make a second layer with the remaining meat mixture another layer of cheese and the rest of the crushed Doritos This double layer ensures every bite is loaded with flavor and crunch
- Bake the Casserole:
- Place the casserole in a three hundred fifty degree oven Bake for fifteen to twenty minutes until the cheese is melty and the top is bubbly Keep an eye so the chips do not get too brown
- Serve with Toppings:
- Spoon out portions onto plates and offer lots of sour cream or fresh pico de gallo These toppings add coolness and freshness to balance the cheesy casserole

The nacho cheese Doritos really make this dish special My kids always want to help crush the chips and layer them in and the cheesy scent takes me right back to after-school snack attacks My sister and I used to race to the dish for the cheesiest crispy edges
Storage Tips
This casserole keeps well in the refrigerator for up to three days Cover tightly with foil or transfer leftovers to airtight containers For longer storage cut into portions and freeze wrapped well Reheat individual pieces in the microwave or oven until hot for best results The chips will soften but the flavor improves
Ingredient Substitutions
You can swap ground turkey or chicken for beef for a lighter option If you want more heat use spicy Doritos or hot Rotel For cheese lovers try a blend of cheddar and pepper jack Gluten-free chips also work if you need to accommodate allergies The casserole base is flexible so get creative
