Can you make a Tater Tot Breakfast Casserole ahead of time?

Yes, the casserole can be made ahead of time and stored in the refrigerator, covered, for up to 12 hours. When ready to bake the casserole, place it in the oven and bake at the same time and temperature as instructed in the recipe.

Tater Tot Breakfast Casserole Substitutions

  • Vegetarian: to make this casserole meatless, substitute vegetables or soy chorizo for the sausage.
    • To make the casserole with vegetables, sauté two cups of veggies along with the onion. I recommend diced bell peppers, sliced mushrooms and/or spinach.
    • To make the casserole with soy chorizo, cook and crumble the soy chorizo just like you would the sausage.
  • Bacon or Ham: Instead of sausage, you can substitute diced ham or cooked, chopped bacon. To do this, simply add the diced ham or chopped bacon to the egg mixture. After the onion has cooked down on the stove, set it aside add add it to the egg mixture with the bacon or ham.

How to reheat a Breakfast Tater Tot Casserole

This tater tot casserole can be reheated in the oven or microwave.

To reheat the casserole in the oven, place slices of the casserole on a foil lined baking sheet and under the broiler in the oven on low. Broil on low for 4-6 minutes, or until the tater tots are crispy and the egg mixture is warm.

To reheat the casserole in the microwave, place slices of the casserole on a microwave-safe plate. Microwave for 2 minutes.

Is a Tater Tot Breakfast Casserole gluten free?

Yes. Most frozen tater tots are gluten free, but always check the label to make sure. Most sausage is also gluten free, but once again, it’s always important to check the label. All other ingredients in the recipe are naturally gluten free.
