This John Wayne Casserole is a hearty, layered dish featuring a base of pressed biscuit dough, topped with seasoned ground beef, sautéed onions and peppers, a creamy blend of sour cream and mayonnaise, and generous layers of Cheddar cheese, fresh tomatoes, and jalapeño peppers, all baked until bubbly and golden.
For a richer flavor, consider using chuck ground beef and ensure it's fully browned before draining excess fat. Slicing the onion and bell pepper uniformly ensures even cooking and a pleasant texture. If you prefer a crispier biscuit base, you can par-bake the pressed biscuit dough for 5-7 minutes before adding the fillings. To prevent the cheese from burning, you might want to add the final layer of cheese during the last 10-15 minutes of baking. A sprinkle of fresh cilantro or sliced green onions after baking will add a vibrant finish and freshness.
