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

Step 1: Prep the Oven and Pan

Preheat your oven to 350°F. Lightly grease a large oven-safe skillet or a 9×13-inch baking dish if your pan is not oven-safe. Having everything ready before you start makes the layering much easier.

Step 2: Cook the Beef and Vegetables

Heat the olive oil over medium heat. Add the diced onion, green bell pepper, and red bell pepper, then cook for 3 to 4 minutes until they begin to soften. Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks. Drain any excess grease.

Step 3: Season the Filling

Sprinkle in the taco seasoning and pour in the water. Stir well so the meat mixture is evenly coated. Let it simmer for 2 to 3 minutes until slightly thickened, then remove it from the heat.

Step 4: Press in the Crust

Flatten the biscuit dough pieces and press them into the bottom of the prepared pan, pinching seams together as needed to form an even layer. Bake the crust for 8 to 10 minutes, just until lightly set but not fully browned.

Step 5: Mix the Creamy Layer

In a medium bowl, stir together the sour cream, mayonnaise, softened cream cheese, garlic powder, chili powder, and black pepper until smooth. Fold in the drained diced tomatoes for a little brightness and texture.

Step 6: Build the Layers

Spread the seasoned beef mixture over the partially baked crust. Spoon the creamy mixture over the beef and spread it gently to cover the surface. Top with the cheddar cheese, Monterey Jack cheese, and jalapeños if using.

Step 7: Bake Until Hot and Bubbly

Return the casserole to the oven and bake for 25 to 30 minutes, or until the cheese is melted and lightly golden around the edges. The center should be hot and the crust should be fully cooked.

Step 8: Rest and Serve

Let the casserole rest for 5 to 10 minutes before slicing. This helps the layers settle and makes serving much cleaner. Finish with chopped green onions right before bringing it to the table.

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

Serve this casserole warm with toppings like shredded lettuce, extra diced tomatoes, sliced olives, avocado, jalapeños, or a spoonful of salsa. It is rich and filling on its own, but it also pairs nicely with a crisp salad, Mexican rice, or simple roasted vegetables.

For storing, let the casserole cool completely before covering it tightly or transferring leftovers to an airtight container. It will keep in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm larger portions in the oven at 325°F until heated through. You can also freeze it for up to 2 months, though the creamy layer is best when enjoyed fresh or refrigerated rather than frozen for long periods.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. You can cook the meat mixture and mix the creamy layer ahead of time, then refrigerate them separately. Assemble and bake when you are ready for dinner, or assemble the full casserole a few hours ahead and refrigerate until baking time.

Can I use ground turkey instead of ground beef?

Absolutely. Ground turkey works well if you want a lighter version. Just make sure to season it well so the filling still has that classic Tex-Mex flavor.

What if I do not have biscuit dough?

You can use crescent dough or a homemade biscuit-style base if needed. Biscuit dough gives the casserole a sturdy, fluffy bottom layer, but other dough options can still work.

Is this casserole spicy?

Not necessarily. The basic version is flavorful more than hot. If you want more heat, add jalapeños, a pinch of cayenne, or use a spicy taco seasoning blend.

Can I add beans or corn?

Yes. Black beans, pinto beans, or corn all fit nicely in this casserole. Stir them into the meat mixture if you want to stretch the filling and add extra texture.

How do I know when it is done baking?

The casserole is ready when the cheese is melted, the edges are bubbling, and the crust is cooked through. A short resting time after baking also helps the layers set properly.
