If you love layered casseroles that combine bold flavor with comforting textures this John Wayne Casserole is a must try. It brings together savory taco spiced beef, creamy toppings, and a tender biscuit crust all baked in one dish. Inspired by cowboy classics but perfected for busy family nights, it is an easy crowd pleaser you will want to make again and again.
My kids light up every time they see this come out of the oven. I first tried it as a way to use up some Bisquick and it quickly became a game day favorite at our house.
Ingredients
- Bisquick mix: essential for a fluffy golden crust look for fresh or unopened packages for best rise
- Ground beef: gives the rich hearty base eighty five percent lean is a good balance of flavor and less grease
- Taco seasoning: adds that classic southwestern kick use your go to brand or homemade mix
- Onion: brings depth and sweetness dice it small for even cooking
- Bell pepper: gives crunch and color choose firm and glossy peppers for the best flavor
- Mayonnaise: helps create a tangy silky topping regular or full fat preferred
- Sour cream: balances flavor with creaminess fresh sour cream will blend smoothly
- Mexican blend cheese: becomes gooey when baked buy blocks and shred yourself for superior melt
- Roma tomatoes: add freshness slice them evenly for pretty layers
- Pepperoncini: provide a gentle heat and zing use jarred coins and pat them dry so the casserole does not get soggy
Instructions
- Prepare the Oven:
- Set your oven to three hundred twenty five degrees and position the rack in the middle. This ensures even baking so every layer cooks through but does not dry out.
- Get the Baking Dish Ready:
- Coat a nine by thirteen inch baking dish with nonstick spray. This not only prevents sticking but makes serving much easier later.
- Cook the Beef:
- In a large skillet cook your ground beef over medium heat breaking it up with a spoon until it is no longer pink. Mix in the taco seasoning and half a cup of water. Simmer for two minutes to let the spices really flavor the meat.
- Sauté the Vegetables:
- Take the cooked meat out of the skillet. Add diced onions and sliced bell peppers to the pan. Sauté for about four minutes until they are fragrant and a little softened but still colorful.
- Mix the Creamy Layer:
- In a medium bowl combine mayonnaise sour cream and three quarters of a cup of cheese. Stir until completely smooth. This will be your tangy topping.
- Make the Biscuit Base:
- In another bowl mix the Bisquick and remaining water until you get a soft dough. Press it into your baking dish forming a solid layer and push it up the sides about a half inch. This forms the base that will absorb all the flavors above.
- Layer the Beef:
- Spoon your seasoned ground beef evenly over the biscuit base. Make sure to cover every corner for full flavor in each serving.
- Add the Vegetables:
- Spread sautéed onions and bell peppers right over the beef. Their sweetness will cut through the richness.
- Spread the Creamy Mix:
- Gently dollop the mayo sour cream mixture on top and smooth it out. This will bake into a rich and tangy layer.
- Top with Tomatoes and Pepperoncini:
- Layer on the tomato slices and scatter the pepperoncini. This adds freshness and a little bite that makes the casserole interesting.
- Finish with Cheese:
- Sprinkle the rest of your shredded cheese over everything. This bakes into a golden bubbly topping.
- Bake:
- Slide the dish into the oven on the middle rack. Bake for thirty to thirty five minutes until everything is set and the cheese is melted and browned at the edges.

I think what makes this dish special is the way the spiced beef and creamy topping combine with the biscuit base. When I first made it for my parents everyone went back for seconds and it is now a potluck tradition in our crew.
Storage Tips
Leftovers can be cooled covered and kept in the fridge up to four days. For best texture reheat slices in the oven or toaster oven instead of microwaving so the biscuit base stays crisp around the edges. This casserole also freezes well in individual portions if you want easy lunches later in the week.
Ingredient Substitutions
Feel free to swap ground turkey or even plant based crumbles for the beef for a lighter version. If you do not have Bisquick you can make a quick homemade biscuit mix using flour baking powder salt and a little butter. Greek yogurt is a fine sub for sour cream adding a touch more tang.
Serving Suggestions
This casserole stands on its own but is also delicious served with a crisp green salad. You can add avocado slices or a dollop of guacamole on top for freshness. Scoop it hot from the dish at the table for casual family style dining.
