Frequently asked questions

What is corn casserole? 

Also known as corn pudding, this dish has been around since the old days when Native Americans used water and corn together to make pone.

They probably shared it with the Europeans who came later, and we put our own spin on it over the years. The basic ingredients are corn, milk, sour cream, eggs, and butter with Jiffy muffin mix.

What can I use instead of cream corn?

You can actually make cream corn by mixing a half-cup of milk and one tablespoon of cornstarch into a can of drained whole kernel corn.

Or, in this recipe, double the whole kernel and add one half cup of whole milk or half and half. Soy or coconut milk can also be used but it will not be as creamy.

What if I don’t have any Jiffy corn muffin mix?

Making muffin mix from scratch is not difficult and you only need a few basic ingredients. Just gather 2/3 cup flour, ½ cup cornmeal, 1/3 cup sugar, 1 tablespoon baking powder, ½ teaspoon salt, and 2 tablespoons of vegetable oil.

Next, mix until there are no lumps, and you have your mixture.  

How to store leftovers:

  1. Store: Store in an airtight bowl or casserole dish for up to three days in the fridge.
  2. Freeze: If you are not going to eat it within the next few days, put it in a freezer bag after it cools down, and then store it in the freezer for up to 90 days. 
  3. Reheat: Warm up your leftovers in the oven at 350 degrees F for 10 minutes or microwave for two minutes.

Recipe tips:

  • Add the sour cream last, right before serving for a creamier texture.
  • Use fresh sweet kernels instead of canned corn if you want a healthier meal.
  • In fact, you can also use frozen corn straight from the freezer.
  • Watch the time on this because you need to cook it until the middle is set but you don’t want the edges to burn.
  • Put a few paper towels between the lid and the pot to catch the moisture so the casserole does not get mushy.
