When it comes to Thanksgiving, the side dishes always steal the show for me. While turkey is the star, I could easily fill my plate with comforting sides like this Corn Au Gratin. This dish is a creamy, cheesy dream with a buttery cracker crust, and the addition of eggs gives it a lovely, souffle-like texture. It’s perfect for the holidays, but the leftovers might just become your new favorite brunch option!

This Corn Au Gratin dish is perfect for feeding a crowd, and the best part? It pairs beautifully with just about anything on your holiday table. Make it once, and you’ll be adding it to your menu year after year–especially when everyone asks for seconds!

Corn Au Gratin

Whether it’s a falltime potluck or a Thanksgiving gathering, this corn casserole is always a hit. It’s optional to add the buttery Ritz cracker topping, as there are crackers also in the casserole. But the cheesy, creamy casserole recipe is always the first to be devoured. It makes a wonderful Friendsgiving 9×13 dish to bring as well.

ingredients to make Corn Au Gratin

Gather these ingredients

  • Eggs
  • Heavy whipping cream
  • Sugar
  • Salt
  • White pepper
  • Bag of frozen corn
  • Ritz Crackers – crushed and separated
  • Sharp Cheddar cheese – grated and separated
  • Unsalted butter
  • Parsley – fresh, finely chopped

How to make Corn Au Gratin

  1. Preheat the oven to 350 degrees F.
  2. Grease a 9×13 inch pan with a cube of butter. Set the unused butter aside.
  3. Whisk together (in a large bowl) the eggs and heavy cream. Add the sugar, salt and white pepper.
  4. Fold in the frozen corn.
  5. Crush the Ritz crackers in a ziplock bag. Add in half of the crackers into the egg mixture, plus ½ cup of the sharp cheddar cheese (shredded).
  6. Add the corn mixture to the baking dish and bake for 35 minutes. Remove from the oven.
  7. Heat up a medium sized frying pan on the stove and melt the remaining cube of butter on medium heat; then add the rest of the crushed Ritz crackers. Saute until browned and the butter is melted in with the crackers.
  8. Remove the corn casserole from the oven, top with the remaining grated cheese and browned crackers. 
  9. Bake 25-35 minutes until golden brown and the center has firmed up (not soft or soggy). The last 10 minutes you may need to add foil on top of the dish to not overcook the buttery crackers.
  10. Cool the dish by removing from the oven and allowing it to sit for 15 minutes. Top with a sprinkle of fresh chopped parsley.
  11. Serve and enjoy!
