Ingredients
2 pounds ground beef

4 eggs

3/4 cup whole milk

1 3/4 cups biscuit mix or Bisquick

Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat the Oven:

Start by preheating your oven to 400°F (204°C). This ensures that your oven is ready to bake the casserole evenly.

Grease the Baking Dish:

Lightly grease a 9×13-inch baking dish with non-stick spray. This step prevents the casserole from sticking to the dish, making it easier to serve and clean up.
