Cheesy corn casserole is a creamy Southern side dish that’s really easy to make from scratch. It’s a delicious Thanksgiving side that is great for kids or a crowd.  With this recipe, you’ll learn how to make your own homemade cornbread mix, too.



For the Homemade Cornbread Mix

  • 2/3 cup all-purpose flour
  • 1/2 cup self-rising yellow cornmeal
  • 1/3 cup granulated sugar
  • 1/4 teaspoon baking powder
  • 1/2 teaspoon salt

For the Casserole

  • 1 15-ounce can whole kernel corn (reserve 1/2 the liquid)
  • 1 15-ounce can creamed corn
  • 1 cup sour cream
  • 1/2 cup salted butter
  • 1 cup extra sharp cheddar cheese, grated (66g)
  • 1 large egg
  • 4 1/2 teaspoons diced pimento
  • 4 1/2 teaspoons thinly sliced green onions (green part only)


Making the Homemade Cornbread Mix

  1. Stir together the flour, cornmeal, sugar, baking powder and salt in a medium sized bowl.  Make sure it's well mixed.

Making the Casserole

  1. Preheat the oven to 350 F.
  2. Put the butter in a 9x9-inch casserole dish, and let it melt in the oven.  Once melted, take the dish out of the oven.
  3. Dump the can of whole kernel corn and half of its liquid into a medium-sized bowl.
  4. Add the creamed corn, sour cream, shredded cheese, pimentos, and green onion and mix well.
  5. Add all the dry ingredients to the wet ingredients and stir well to combine.
  6. If desired, let the corn batter sit for 5 minutes in the bowl for a lighter texture and a higher rise.
  7. Pour all the ingredients into the hot, buttered casserole dish.  Be careful, as the dish is still hot.
  8. Bake for 1 hour, then check to see if it's done.  It may need another 10 minutes.  It will be done when it has a golden brown, cracked top, and a toothpick inserted into the center comes out clean.  Serve warm.


  • If you want to add more color, try diced red, yellow, and orange sweet peppers or cilantro.
  • Make your own cornbread mix.
  • Use fresh or frozen corn instead of canned.
  • Let the corn batter rest for 5 minutes before baking for a lighter texture and a higher rise.
