Parmesan Garlic Corn Au Gratin ingredients

To Make This Parmesan Garlic Corn Au Gratin You Will Need:

  • frozen sweet corn
  • heavy whipping cream
  • kosher salt
  • sugar
  • unsalted butter
  • unbleached all-purpose flour
  • ground black pepper
  • grated parmesan cheese

Start by adding 16 ounces of frozen sweet corn to a saucepan.

To that add 2 tablespoon sugar and 1 teaspoon kosher salt.

Pour in 1-1/4 cup of heavy whipping cream.

Stir and bring to a boil.

Once boiling, reduce the heat to medium-low and simmer for 5 minutes, stirring occasionally.

After 5 minutes, turn off the heat and cover the pan, leaving the pot still on the burner.

Next, make a roux by adding 2 tablespoons butter and 1 large minced clove of garlic to a small skillet. Heat over medium to medium-low until melted. Then cook the garlic for 30 to 60 seconds.

Whisk in 2 tablespoons unbleached all-purpose flour.

Whisk until smooth.

Remove the lid from the cream and corn mixture and add in the roux, 1/4 cup freshly grated parmesan cheese and 1/8 teaspoon freshly ground black pepper -or to taste.

Stir until thickened.

Transfer the creamy corn mixture to a small un-greased casserole dish. I believe this one is 10×7 but I could’ve went even smaller, I think.

Move your oven rack to about 3 inches from heating element and preheat your broiler. Sprinkle the remaining 1/4 cup of parmesan over top.

Slip the casserole under the broiler until the top gets golden in spots.

Feel free to sprinkle a little minced parsley over top for a pop of color.

This side dish couldn’t be any easier nor more delicious. The sweet corn contrasts deliciously with the parmesan and garlic.

I serve this with ham but also with roasted chicken. It’s pretty universal and that crisp parmesan topping
