Ingredients

1 pound ground beef

1 small onion, chopped

1 (10.5 oz) can cream of mushroom soup

1 (10.5 oz) can cream of chicken soup

1 (10 oz) can diced tomatoes with green chilies

1 (15 oz) can corn, drained

1 (14 oz) bag corn chips

2 cups shredded cheddar cheese

Instructions

Step 1: Cook the Beef and Onion

In a large skillet over medium-high heat, combine the ground beef and chopped onion.

Cook until the beef is fully browned and the onion is soft, about 7–10 minutes. Drain off any excess grease.

Step 2: Combine the Filling

Reduce the heat to low. Stir in the cream of mushroom soup, cream of chicken soup, diced tomatoes with green chilies, and drained corn.

Mix until everything is evenly combined and heated through, about 3–5 minutes.

Step 3: Layer the Casserole

Preheat your oven to 350°F (175°C). In a 9×13-inch baking dish, start by layering corn chips on the bottom.

Spread half of the beef mixture over the chips, then sprinkle 1 cup of shredded cheddar cheese on top.

Repeat with another layer of corn chips, the remaining beef mixture, and top it off with the rest of the cheese.

Step 4: Bake

Place the dish in the preheated oven and bake uncovered for 25–30 minutes, or until the cheese is fully melted, bubbling, and slightly golden.

Step 5: Cool and Serve

Remove the casserole from the oven and let it rest for 5–10 minutes before serving.

This helps it set for easier slicing and serving.

Recipe Notes

Use a Large Skillet: Make sure your skillet is big enough to hold the beef, onion, and all the soup-based filling. A crowded pan can make it harder to mix evenly.

Drain the Ground Beef Well: After browning the beef and onion, drain off the grease thoroughly to prevent the casserole from becoming oily.

Mix Filling While Warm: Stirring in the soups, tomatoes, and corn while the pan is still warm helps everything blend smoothly and cuts down on baking time.

Freshly Shred Your Cheese: Pre-shredded cheese works fine, but shredding from a block gives you smoother, creamier melting without added starches or fillers.

Layer Chips Just Before Baking: To keep them crispy, don’t layer the corn chips too early. Assemble and bake immediately for the best texture.

Let It Rest Before Serving: Give the casserole 5–10 minutes after baking to cool and set up. This makes it easier to cut and keeps it from falling apart on the plate.

Use a Sturdy Spatula: Since the casserole is layered with chips and melted cheese, a wide, flat spatula helps serve it neatly.

Customize Heat Level: If you like it spicier, choose “hot” diced tomatoes with green chilies or stir in a bit of hot sauce or diced jalapeños to the filling.
