How to Make John Wayne Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with non-stick spray or a little butter. This will prevent your casserole from sticking to the dish as it bakes.
Step 2: Cook the Ground Beef and Veggies
In a large skillet over medium heat, brown 1 pound of ground beef, breaking it apart with a wooden spoon. Once it’s nearly cooked, add the chopped onion and bell pepper, and sauté until the vegetables soften, about 5-7 minutes.
Step 3: Add Seasoning and Tomatoes
Once the vegetables are tender, stir in the taco seasoning and diced tomatoes with green chilies. Let everything cook together for an additional 3-5 minutes, allowing the flavors to meld.
Step 4: Prepare the Biscuit Base
While the beef mixture is cooking, open the can of refrigerated biscuits and spread the dough evenly across the bottom of your prepared baking dish. Pop the dish into the preheated oven for 5 minutes to pre-bake the biscuits. This helps them start to puff up and ensures they’ll bake all the way through later.
Step 5: Assemble the Casserole Layers
Remove the pre-baked biscuit crust from the oven. Spread the beef mixture evenly over the biscuit layer.
Step 6: Make the Creamy Ranch Topping
In a medium bowl, mix together 1 cup sour cream, 1 cup mayonnaise, and 1 packet of ranch dressing mix. Spread this mixture evenly over the beef layer.
Step 7: Add Cheese and Jalapeños
Sprinkle the top of the casserole with 1 cup shredded cheddar cheese and 1 cup shredded Monterey Jack cheese. If you’re a spice lover, scatter the sliced jalapeños on top for some extra heat.
Step 8: Bake the Casserole
Place the assembled casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is melted, bubbly, and golden. The biscuit crust should also be cooked through by this time.
Step 9: Let Cool and Serve
Once done, allow the casserole to cool for a few minutes before slicing and serving. Enjoy this creamy, cheesy, beefy masterpiece with your favorite side dishes, or on its own for a filling meal.
Tips for Success
Pre-bake the biscuits: Don’t skip the step of pre-baking the biscuit layer. It ensures that the base isn’t doughy or undercooked.
Spice it up: If you love heat, feel free to double up on the jalapeños or add extra hot sauce to the beef mixture.
Make it your own: Feel free to add more veggies to the beef mixture, like corn, black beans, or even chopped zucchini for extra nutrients and texture.
