Ingredients
The Savory Beef Base:
- 2 lbs ground beef
- 1 package (1 oz) taco seasoning
- ¾ cup water
- 1 small white or yellow onion, diced
- 1 green bell pepper, diced
- 2 cups shredded Colby Jack or Cheddar cheese (divided) [2, 3]
The Creamy Batter Topping:
- 2 cups biscuit baking mix (such as Bisquick)
- ¾ cup water
- ½ cup sour cream
- ½ cup mayonnaise [2, 3]
Instructions
- Preheat & Prep: Heat your oven to 325°F (165°C). Lightly spray a 9×13-inch baking dish with non-stick cooking spray. [3]
- Brown the Beef: In a large skillet over medium-high heat, cook and crumble the ground beef until completely browned. Drain any excess grease from the pan. [3]
- Season the Meat: Stir the taco seasoning, ¾ cup water, diced onions, and diced bell peppers into the skillet. Let it simmer for 3 to 5 minutes until the liquid absorbs and the vegetables soften slightly. Transfer the mixture into the bottom of your prepared baking dish. [2, 3]
- First Cheese Layer: Sprinkle 1 cup of the shredded cheese evenly over the warm ground beef layer. [3]
- Mix the Pourable Crust: In a medium bowl, combine the biscuit mix, ¾ cup water, sour cream, and mayonnaise. Stir together until a thick, smooth, pale-yellow batter forms.
- Pour & Top: Slowly pour the creamy batter directly over the cheese and beef layers (as shown in the video clip). Use a spatula to spread it evenly to the edges. Finish by topping the batter with the remaining 1 cup of shredded cheese. [1, 3]
- Bake: Place the casserole uncovered into the oven and bake for 30 to 35 minutes. The edges should be bubbly and the cheese topping completely melted and golden brown. [2, 3]
- Rest & Serve: Let the dish cool for 5 to 10 minutes before slicing so the layers settle nicely.
