Ingredients
Method
Preparation
- Preheat the oven to 350°F and grease a 9x13-inch casserole dish with cooking spray.
- Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it up, until no pink remains (about 6–8 minutes). Drain any excess fat.
- Return the skillet to medium heat. Add the chopped onion and bell pepper to the beef, cooking until softened, about 4 minutes. Sprinkle in the taco seasoning and stir to coat evenly. Remove from heat.
- In a medium bowl, mix the biscuit mix and 1 cup water until just combined. Spread the dough into the prepared casserole dish in an even layer. Bake the biscuit layer for 5–8 minutes — it should be set but not fully browned.
Assembly
- Spoon the cooked beef mixture over the par-baked biscuit base in an even layer.
- In a separate bowl, stir together sour cream, mayonnaise, drained diced green chiles, ¾ cup of the shredded cheese, and garlic powder until smooth. Spread this mixture over the beef.
- Dollop the salsa across the top, then sprinkle with the remaining ¾ cup of cheese.
Baking
- Bake uncovered for 30 minutes, until the casserole is bubbling and the cheese is melted and lightly golden. Let rest 5–10 minutes before serving.
Notes
Par-baking the biscuit layer prevents a gummy center and helps the casserole slice neatly.
