Ingredients
Method
- Preheat your oven to 325°F. Grease a 9x13 inch baking dish with butter or cooking spray and set aside.
- In a large skillet over medium-high heat, add the ground beef. Break it up with a wooden spoon and cook until fully browned, about 6 to 8 minutes. Drain the grease thoroughly.
- Return the beef to the skillet and add 1 cup of water and the taco seasoning. Stir well and let simmer for 4 minutes until most of the liquid has been absorbed.
- Add the diced onion, drained Rotel tomatoes, and drained corn to the skillet. Stir everything together and reduce heat to low while you prepare the other layers.
- In a medium bowl, combine the Bisquick mix and 1 cup of water. Stir until a sticky dough forms. Do not overmix.
- Dump the Bisquick dough into the prepared baking dish and spread it out evenly across the bottom using your hands or a spatula.
- Spoon the ground beef mixture over the biscuit dough layer and spread it out evenly, reaching all corners of the dish.
- In a separate bowl, combine the cream cheese, mayonnaise, garlic powder, and salt. Beat with an electric mixer or whisk until smooth and creamy.
- Dollop the cream cheese mixture over the beef layer and spread it as evenly as possible using the back of a spoon. It's thick, so it won't cover perfectly, and that's okay.
- Sprinkle the shredded mozzarella and cheddar cheese evenly over the top of the casserole.
- Place the baking dish in the preheated oven and bake for 40 minutes, or until the cheese is melted and golden and the biscuit base is cooked through.
- Remove from the oven and let the casserole rest for 5 minutes before slicing and serving. This helps it set and hold together better.
Notes
Make-Ahead: Assemble the casserole completely, cover tightly, and refrigerate for up to 24 hours. Bake as directed, adding 5-10 extra minutes to the baking time.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven at 350°F.
Freezing: Freeze unbaked or baked casserole for up to 3 months. Thaw overnight in the refrigerator before baking or reheating.
