Ingredients
- 1 pound ground beef
- 1 medium onion, chopped
- 1 medium bell pepper, chopped
- 1 (10-ounce) can diced tomatoes with green chilies, drained
- 1 packet taco seasoning
- 1 (8-ounce) can refrigerated biscuits
- 1 cup sour cream
- 1 cup mayonnaise

These key ingredients perfectly balance flavors and textures, creating a scrumptious, crowd-pleasing casserole. The ground beef provides a hearty protein base, while the tomatoes and bell peppers add freshness and slight acidity, complementing the seasoning beautifully.
Step-by-Step Instructions
1. Preheat your oven to 350°F (175°C). This will ensure your casserole cooks evenly.
2. In a skillet, brown the ground beef over medium heat. Make sure to break it up into small crumbles as it cooks. Once the beef is about halfway cooked, add the chopped onion and bell pepper. Cook until both vegetables have softened, which typically takes around 3-5 minutes.
3. Stir in the drained diced tomatoes and packet of taco seasoning. Mix everything together well so the flavors meld. Allow this to simmer for a couple of minutes.
4. Spread the flavorful meat mixture in the bottom of a greased casserole dish. Ensure it’s distributed evenly for consistent cooking.
5. In a separate bowl, combine the cup of sour cream with the cup of mayonnaise. This mixture will add creaminess and enhance the flavors. Spread this mixture generously over the meat layer.
6. Take the refrigerated biscuits and cut each one into quarters, arranging them neatly on top of the casserole. This will form a delightful, golden-brown crust during baking.
7. Bake in the preheated oven for 25-30 minutes. You’ll know it’s ready when the biscuits are golden brown and cooked through. Keep an eye on it to avoid overbaking.
8. Once out of the oven, let the casserole cool for a few minutes before serving. This brief cooling period allows the layers to set slightly, making it easier to serve.
Creative Ways to Serve This Casserole
This dish is versatile and works well on its own, but there are plenty of ways to elevate your meal. Pair John Wayne Casserole with a simple side salad tossed with a vinaigrette dressing for a refreshing contrast. Alternatively, some tortilla chips can add a nice crunch and an authentic taco feel. If you’re feeling indulgent, serve it with some guacamole or sour cream on the side for dipping. This meal is great for family dinners, potlucks, or game day gatherings!
Keeping Leftovers Fresh
If you happen to have any leftovers, you can store them in an airtight container in the fridge for up to 3-4 days. Make sure it cools down to room temperature before sealing for the best results. If you wish to keep it longer, consider freezing individual portions, which can last up to 2-3 months. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight and reheat in the oven or microwave until warmed through.
Expert Cooking Tips
To elevate your casserole, consider browning the ground beef with garlic or adding some chopped jalapeños for an extra kick. Ensure not to overcook the beef initially; it will finish cooking in the oven. Also, if you want a rich flavor, try using shredded cheese in the creamy layer before applying the biscuit topping. Lastly, keep an eye on the biscuits while baking to prevent them from burning, especially if your oven runs hot.
Variations and Substitutions
There are many ways to customize John Wayne Casserole according to your tastes or dietary preferences. If you prefer a leaner option, ground turkey or chicken can replace the beef. You could also incorporate black beans or corn for additional nutrition and flavor. For a vegetarian version, simply replace the ground beef with an extra couple of cups of your favorite vegetables or a meat substitute. You can switch out the canned tomatoes for fresh if you have them on hand, and feel free to use reduced-fat sour cream and mayonnaise for a lighter recipe.
