Prepare your baking dish by generously coating the bottom and sides with butter to help your casserole not stick.
Place the refrigerator biscuits on the bottom of the baking dish. Press them down to fill the whole bottom layer as best as possible. Don’t worry about making the biscuit dough connect, just try to fill the bottom layer.
1 package refrigerated canned biscuits
The next layer is the frozen tater tots, then the browned turkey sausage.
1 package tater tots, 16 ounces turkey sausage
In a medium-sized bowl, scramble the 12 eggs and whisk the softened butter with the eggs. Pour this egg mixture over the layers in your baking dish.
12 large eggs, ½ cup butter
Top the egg mixture with a sprinkle of your cheddar cheese, onion, and red bell pepper. Add salt and pepper.
8 ounces cheddar cheese, ⅓ cup Vidalia onion, ¼ cup red bell pepper, salt and pepper to taste
Cover with foil and bake on the center rack for 40 minutes.
Remove the foil and continue baking for an additional 20 minutes or until the eggs are fully cooked and the casserole comes together and is browning.
Allow the casserole to sit 5 to 10 minutes before cutting. Garnish with green onions.
