Recipe Variations

Let your creativity flow, and add or change the ingredients in your cheesy potato casserole with cornflakes. Here are several suggestions to help get you started: 

  • Change the sauce liquid. Instead of cream of mushroom soup, try cream of chicken canned soup, cheesy Alfredo sauce, or a simple bechamel. 
  • Add some protein. Toss in cubed ham, chopped cooked sausages, or browned ground beef to make the casserole more filling. 
  • Switch out the topping. Use crushed Ritz crackers or saltines instead of cornflakes.
  • Load the casserole up with veggies. Diced bell peppers, sauteed spinach, cooked mushrooms, or even a can of Ro-Tel will taste great.

Whether you make this casserole a main or a side, it pairs well with many different types of food. Here are a few options:

  • Scrambled eggs, sausage, and bacon. Turn these cheesy potatoes with buttery cornflakes into a delicious side dish for brunch by serving them with your favorite breakfast items. 
  • A side salad. Simple mixed greens with an acidic dressing will cut through the richness of cheesy potatoes with cornflakes. 
  • Roasted meat or chicken. Substitute this casserole for mashed or baked potatoes. The casserole is terrific when matched with a juicy steak, pork chops, or ham.

    My family calls this Aunt Pam’s Perfect Potato Casserole. And we use any cream soup not just cream of chicken. Cream of mushroom gives an earthy flavor and cream of celery adds a bright, crisp hint of spring.
