What kind of Potatoes are used in Breakfast Casserole?

  • Idaho, Yukon gold, Russet or red potatoes will all work in a breakfast casserole.
  • The potatoes may be grated, if desired, instead of the cubed option per instructions. If grating potatoes, they don’t need to be boiled for 5 minutes.

What kind of Cheese Can be Used in Breakfast Casserole?

  • You can use your favorite cheese! I typically use a Colby Jack or Mexican cheese for the casserole dish. A mixture of Mozzarella and Mild Cheddar may be combined to use in the recipe.

However, fresh avocado and tomatoes with cilantro or green onion add even more flavor to the dish.!
