How to Make Taco Doritos Casserole
Step 1: Preheat the Oven

Step 2: Prepare the Baking Dish
Spray your 9×13 baking dish with nonstick spray to prevent sticking.

Step 4: Cook the Beef and Onion
In a large skillet over medium heat, cook the ground beef and diced onion until the meat is browned. Drain any excess grease to keep the dish lighter.
Step 5: Add Garlic
