Step-by-Step Instructions
- Prepare the Baking Dish:
- Spray a nine by thirteen inch dish with nonstick spray and preheat your oven to three hundred fifty degrees This ensures your casserole comes out easily and the edges crisp without sticking
- Mix the Biscuit Layer:
- Stir Bisquick and water in a large bowl until you get a soft sticky dough If needed use a spatula sprayed with nonstick spray to help spread it evenly in the dish You want a flat even base covering the bottom
- Cook the Beef and Vegetables:
- Heat a large skillet over medium high Add ground beef onion and bell pepper Cook until beef is browned and onions are soft this usually takes five to six minutes Drain off any excess grease so your casserole isn’t soggy
- Flavor the Meat:
- Sprinkle in taco seasoning then pour in the Rotel and add corn Stir everything for another two to three minutes so the flavors come together with a bit of sauce
- Layer the Casserole:
- Spoon the beef mixture evenly over the biscuit base Smooth it lightly so every bite gets both
- Mix the Creamy Topping:
- Combine sour cream mayonnaise and one and a half cups shredded cheese in a small bowl Mix well and spread gently over the beef layer so you get a creamy blanket
- Add Cheese and Bake:
- Sprinkle the rest of the shredded cheese on top Place uncovered in the oven and bake for thirty five to forty minutes until the topping is bubbly and golden brown Let cool at least five minutes before slicing to help set the layers

My favorite part is the creamy topping every time it comes out of the oven bubbling and crisp at the edges The scent reminds me of every football Sunday when my husband and I would scoop big cheesy bites while cheering on our team
