This hearty John Wayne Casserole Bake transforms simple ingredients into a robust, crowd-pleasing meal that satisfies even the hungriest cowboys at your table. The layers of seasoned beef, sautéed vegetables, and creamy cheese blend create a harmonious dish that delivers comfort with every bite.
I first made this casserole when hosting my extended family for a weekend gathering. The empty dish and requests for seconds told me everything I needed to know this would become a regular in our dinner rotation. Now it appears on our table at least twice a month.

How To Make John Wayne Casserole Bake
- Prepare the oven
- Heat your oven to 165°C with the rack positioned in the center. Take a moment to thoroughly grease your 33x23 cm baking dish with nonstick spray to ensure easy serving later.
- Brown the beef
- Place a large skillet over medium high heat until hot. Add the ground beef and break it apart with a wooden spoon while it cooks. Continue stirring until all pink disappears about 7 to 8 minutes. Sprinkle the taco seasoning evenly over the meat then pour in 120 ml water. Allow the mixture to simmer for a full 2 minutes so the meat absorbs all the flavors. Transfer the seasoned beef to a bowl.
- Sauté the vegetables
- Return the same skillet to medium heat. Add the diced onion and sliced bell pepper to the pan. Cook for approximately 4 minutes stirring occasionally until the vegetables soften and the onions become translucent. The residual beef flavor in the pan will enhance the vegetables.
- Mix the creamy layer
- In a medium bowl combine mayonnaise sour cream and 90 g of the shredded Mexican cheese. Stir until completely smooth and well blended. This mixture creates the rich creamy center of the casserole.
- Prepare the dough base
- In a separate bowl stir together the Bisquick mix and remaining 240 ml water until a soft dough forms. Use your fingers or a spatula to press the dough evenly across the bottom of your prepared baking dish creating a slight rim around the edges.
- Layer the casserole
- Start with the prepared dough base. Spread the seasoned beef in an even layer covering the dough completely. Next distribute the sautéed vegetables evenly across the meat layer. Carefully spread the creamy cheese mixture on top of the vegetables using an offset spatula for the smoothest application.
- Add the final toppings
- Arrange the sliced Roma tomatoes in rows across the top then scatter the sliced pepperoncini evenly throughout. Finish by sprinkling the remaining 180 g of Mexican cheese blend over everything ensuring complete coverage.
- Bake to perfection
- Place the assembled casserole on the center rack of your preheated oven. Bake for 30 to 35 minutes watching for the cheese to turn golden brown and the edges to bubble. The bottom crust should be completely cooked through.
The taco seasoning truly transforms this dish from simple to spectacular. I always keep several packets in my pantry specifically for this recipe. One memorable summer evening, my usually picky nephew devoured two full servings and declared it better than his favorite restaurant meal which certainly made this aunt very proud.
Storage Solutions
This casserole keeps beautifully in the refrigerator for up to 3 days when stored in an airtight container. For best results, reheat individual portions in the microwave for about 2 minutes on medium power, or warm larger portions in a 150°C oven until heated through, about 15 minutes. You can also freeze portioned leftovers for up to 2 months. Thaw overnight in the refrigerator before reheating for the best texture restoration.
Easy Substitutions
The beauty of John Wayne Casserole lies in its adaptability. Ground turkey works perfectly as a leaner alternative to beef. No Bisquick on hand? Create your own by combining 2 cups flour, 1 tablespoon baking powder, 1 teaspoon salt, and 1/3 cup butter. Lactose sensitive diners can enjoy this with dairy free cheese alternatives and plant based sour cream, though the texture will be slightly different. For a spicier version, add jalapeños or use hot taco seasoning instead of regular.

The History Behind The Name
Despite its rugged cowboy name, John Wayne Casserole has murky origins. Some claim the Duke himself enjoyed a version of this hearty dish, while others suggest it was created in his honor after his passing. The most likely story traces it back to a recipe the actor contributed to a charity cookbook in the 1970s, though that original version was quite different from today's layered creation. Regardless of its exact beginnings, this robust, satisfying casserole certainly embodies the straightforward, hearty spirit of the American West that Wayne represented in his films.
