Ingredients and Variations

Serve this hearty dish for breakfast, brunch, lunch, or dinner because it goes with everything from eggs to chicken or beef!

POTATOES: Diced potatoes make this dish hearty and gives it texture; however regular shredded hash browns or even leftover mashed potatoes can be used.

CHEESE: Sharp cheddar has a robust flavor in this dish, but milder flavored cheeses like a Mexican blend, mozzarella, or Monterey Jack will work, or try a combination of what’s in the fridge!

SAUCE: Canned soup is so versatile! Try other soups like cheddar cheese or even cream of mushroom, if desired. Sour cream can be replaced with Greek yogurt for fewer calories and a tangier taste.

SEASONINGS: Salt and onion powder bring up the flavors, but for a new twist, stir in your favorite taco, chili, or Italian blends.

EXTRAS: Make cheesy potato casserole with chopped breakfast sausage links, diced ham, or bacon pieces or add leftover veggies.
