Ingredients for the One-Pan Cheesy Tex-Mex John Wayne Casserole

Every ingredient in this casserole has a job to do, and together they build those signature savory, creamy, cheesy layers.

Refrigerated biscuit dough

This creates the base of the casserole and gives the dish a hearty, comforting foundation that holds the filling well.

Ground beef

Ground beef brings the rich, savory flavor that makes this casserole feel like a complete and satisfying dinner.

Onion

Onion adds sweetness and depth as it cooks with the beef, helping the filling taste fuller and more balanced.

Red bell pepper

Red bell pepper adds a mild sweetness and a little color that brightens the casserole.

Green bell pepper

Green bell pepper gives the filling a slightly sharper, classic Tex-Mex flavor.

Taco seasoning

This is what gives the beef its bold, smoky, seasoned character without needing a long list of spices.

Diced tomatoes with green chiles

These bring moisture, tang, and gentle heat while helping the filling stay juicy.

Sour cream

Sour cream makes the creamy layer smooth and slightly tangy, which balances the richness of the meat and cheese.

Mayonnaise

A little mayonnaise adds body to the creamy topping and helps it bake up velvety rather than dry.

Sharp cheddar cheese

Sharp cheddar adds bold cheesy flavor and that gorgeous golden top.

Monterey Jack cheese

Monterey Jack melts beautifully and gives the casserole an extra creamy finish.

Fresh parsley

A sprinkle of parsley at the end adds freshness and a pop of color that wakes up the rich flavors.

How To Make the One-Pan Cheesy Tex-Mex John Wayne Casserole

This recipe comes together in layers, and each step is simple. Once the base is baked and the filling is cooked, the oven does the rest.

Step 1: Prep the oven and pan

Preheat your oven to 350°F. Lightly grease a 9×13-inch baking dish or oven-safe pan so the casserole lifts easily after baking.

Step 2: Form the biscuit base

Press the refrigerated biscuit dough evenly across the bottom of the dish, pinching seams together to make one even layer. Bake for a few minutes until the dough is just beginning to set.

Step 3: Cook the beef and vegetables

In a large skillet, cook the ground beef with the onion, red bell pepper, and green bell pepper until the beef is browned and the vegetables have softened. Drain any excess grease so the casserole does not get oily.

Step 4: Season the filling

Stir in the taco seasoning and diced tomatoes with green chiles. Let the mixture simmer for a few minutes so the flavors blend and the filling thickens slightly.

Step 5: Mix the creamy layer

In a bowl, stir together the sour cream, mayonnaise, and part of the shredded cheese. This mixture adds the signature creamy richness that makes the casserole stand out.

Step 6: Build the layers

Spread the beef mixture over the biscuit base. Spoon the creamy cheese mixture over the top and gently spread it across the surface. Finish with the remaining shredded cheese.

Step 7: Bake until bubbly

Return the dish to the oven and bake until the cheese is fully melted and golden and the edges are bubbling. The casserole should look set and smell deeply savory.

Step 8: Rest and garnish

Let the casserole rest for about 10 minutes before slicing. Sprinkle with fresh parsley and serve warm.

Serving and Storing One-Pan Cheesy Tex-Mex John Wayne Casserole

This casserole feeds about 8 people, which makes it a great choice for family dinners, potlucks, or meal prep. Serve it hot from the baking dish with your favorite toppings like sliced jalapenos, chopped cilantro, sour cream, or diced avocado if you want to lean even more into the Tex-Mex flavor.

For storing, let leftovers cool completely, then cover and refrigerate for up to 4 days. Reheat individual portions in the microwave or warm larger portions in the oven until heated through. You can also freeze it in tightly wrapped portions for a future easy dinner.

What to Serve With One-Pan Cheesy Tex-Mex John Wayne Casserole

Crisp green salad

A simple salad with romaine, tomatoes, and a lime vinaigrette adds freshness next to the rich casserole.

Fluffy rice works beautifully with the seasoned beef and helps turn the meal into an even heartier dinner.

Refried beans

Creamy beans pair naturally with the Tex-Mex flavors and make the plate feel complete.

Corn on the cob

Sweet corn adds a juicy, buttery contrast that tastes especially good with the cheesy topping.

This makes the meal feel casual and fun, and the cool creamy guacamole balances the warm casserole nicely.
