  • 16 ounces sweet corn frozen
  • 1-1/4 cups heavy whipping cream
  • 1 teaspoon kosher salt
  • 2 tablespoons sugar
  • 2 tablespoons unsalted butter
  • 1 clove garlic finely minced
  • 2 tablespoons unbleached all-purpose flour
  • black pepper freshly ground, to taste
  • 1/2 cup parmesan cheese grated


  • Move an oven rack 4 inches from the heating element of your oven, then preheat your broiler.
  • In a large 3 quart saucepan (with lid) add the frozen corn, cream, salt and sugar. Bring to a boil, reduce and simmer for 5 minutes, stirring occasionally. Then cover the pot and turn off the heat.
  • Meanwhile, make a roux. In a small sauté pan, add butter and garlic. Heat over medium-low, once the butter has melted, cook the garlic 1 minute. Stirring often.
  • Sprinkle in the flour, stirring until smooth. Cook for 1 minute.
  • Add the roux, 1/4 cup parmesan and lots of ground black pepper to the corn. Stir to combine. It should thicken.
  • Transfer the creamy corn to a small oven-safe casserole dish. Sprinkle with the remaining parmesan before slipping it under the broiler for 2 minutes or until golden brown in spots. Watch carefully to avoid burning.
  • Serve immediately.
