How to Make

Recipe Tips

  • This dish can be prepped and placed in the baking dish ahead of time. Store covered airtight in the refrigerator and note that you’ll need to extend the baking time since the casserole will be chilled.
  • This recipe makes a 9 x 13 casserole dish and will serve at least 8. It’s easy to make half a batch for a smaller group. The photo above is a half-batch.
  • I used two types of cheddar cheese, sharp and mild, but you can use any combination of cheeses you like with potatoes. I’d suggest Gruyere and a mild cheddar for another nice pairing.
  • You can bake your potatoes instead of boiling them for a more mealy classic baked potato texture.

Frequently Asked Questions

What Should You Serve with a Baked Potato Casserole?

A simple entree like roast chicken, grilled pork, or beef would be a delicious pairing. I’d also suggest a nice green salad and roasted vegetables.

How Long Can You Store a Baked Potato Casserole?

If not left out at room temperature longer than 2 hours, cover the top with foil or plastic wrap so it’s airtight, and store the leftovers for 3-4 days in the refrigerator.

Can You Freeze a Potato Casserole?

Since the potatoes in the casserole are cooked, the casserole will freeze well. Wrap it airtight in a couple of layers of foil to prevent freezer burn. You can defrost it overnight in the refrigerator to shorten the cooking time.

How Can You Garnish a Potato Casserole for Company?

Right before serving, sprinkle the top of the casserole with minced parsley, minced chives, or sliced green onions. The pop of green is a great contrast to the melted cheese topping.
