What is Corn Casserole?

Corn casserole, sometimes known as corn pudding, can be described as a cross between cornbread and a souffle. It’s believed to have had its beginnings with Native Americans who combined corn and water to create what we know as corn pone. The crunchy, caramelized top makes this Instant Pot version irresistible!

How Do I Store Corn Casserole?

Instant Pot Corn Casserole can be refrigerated for 3-5 days after it’s completely cooled, and reheated when you’re ready to eat it.

The microwave tends to make leftovers mushy when reheated, so use the oven instead. For best results, wrap in foil and reheat in a 375-degree oven. Time will depend on the quantity heated. Check the temperature after 10-15 minutes.

Can I Freeze Instant Pot Corn Casserole?

You won’t want any to go to waste so wrap leftovers tightly in plastic wrap and then aluminum foil. Freeze for up to three months and reheat for another delicious addition to a weekday meal. Allow frozen leftovers to completely thaw before reheating them.

Can I Make Instant Pot Corn Casserole in the Oven Instead?

Yes, you can! If you have room in the oven, bake this at 350 for 35-50 minutes. Check it after 35 minutes, then bake until it’s set. Flip the broiler on, top with cheese, and toast up the top if you want.

Tips for Making Instant Pot Corn Casserole

  • You can make this recipe ahead and reheat it when you want to serve it. Keep it in the fridge, tightly wrapped, for up to three days, but it’s best to serve it the next day for the freshest-tasting casserole.
  • Sauteing canned corn before adding it to the recipe will reduce some of the liquid. Excess liquid in your casserole can make it mushy, so drain it well!

  • You can serve it in the pan but if you want to remove it, gently run a knife around the outside and flip it out onto a serving dish.
  • Be careful when removing this from the Instant Pot. If the top of the casserole feels too jiggly (like it may be wet inside), reset the Instant Pot for another 5 minutes and allow it to cook again. Allow the 5-minute natural release as well.
  • You can use a cake pan or a spring form pan for this recipe.

  • Butter – you can substitute margarine or soy butter in this recipe with no difference in taste.
  • Sour cream – Greek yogurt or low-fat sour cream can be used as a simple substitution in equal parts.
  • Cheese – Use pepper jack or Mexican blend to give your casserole a bit of spicy flavor.
  • Jalapeños – You can make this less spicy by using green onions instead of chilies or jalapeños. You can leave them out completely, but then your casserole will have less color and flavor.
  • Corn – Frozen or fresh corn can be used in place of canned corn. (First cook and cut off the cob before use.)
