Ingredients & Variations

CHEESE Sharp Cheddar is best in this dish, it really gives the casserole that strong cheesy flavor. Try Monterey Jack, mozzarella or Havarti to switch it up a bit!

SAUCE Condensed cheddar cheese soup is added but any ‘cream of’ soup you have on hand works! You can also make homemade condensed cream of mushroom to use in this recipe if you prefer!

Sour cream adds a bit of tang and creaminess, try plain Greek yogurt in place if it’s what you have on hand.

SEASONINGS Garlic powder and onion powder are my go-to in this recipe. Add cajun seasoning or taco seasoning to kick it up a notch!

Optional Additions

This casserole is so versatile. Use any leftovers or extra ingredients you have on hand!

 MEAT Breakfast sausage, leftover ham, bacon, ground beef, or chicken.

VEGGIES Diced bell peppers, broccoli or cauliflower florets, yellow or green onion, leftover zucchini, or diced tomatoes.
