Cheesy Corn Casserole Ingredients

A full recipe card, including exact ingredient amounts, appears at the bottom of this post.

  • canned sweet corn – the star of the show! We used canned corn (whole kernel corn) here, but you can also use thawed frozen corn, or even fresh corn if it’s in season.
  • milk and cream – these dairy components add richness and creaminess to the corn casserole with cheese.
  • butter – the fat component of the roux that will thicken the sauce.
  • all-purpose flour – acts as the thickening agent for the creamy sauce, helping it cling to the corn.
  • cheese – we use a combination of Monterey Jack and Cheddar, but you can use all one or the other, or experiment with other cheeses. You can also use sharp cheddar or extra sharp cheddar for a stronger cheese flavor.
  • onion powder and garlic powder – these add depth and complexity to the dish without being overpowering.
  • sugar – brings out the natural sweetness of the corn and balances the savory elements.
  • salt and pepper – enhances all of the other flavors in this corn and cheese casserole.
  • bacon – crisp Oven Bacon adds a savory saltiness that balances the sweet corn. You can also use Oven Baked Turkey Bacon if you prefer.
  • chopped fresh parsley – an optional garnish for this corn and cheese casserole, if you want. A sprinkle of green onions on top is also nice!

Cheese And Corn Casserole Home Chef Tips

  • This cheesy corn recipe can keep in the fridge, tightly wrapped, for 2 to 3 days before baking. Bring to room temperature for one hour before baking according to the recipe instructions below.
  • Feel free to experiment with other cheeses, like Parmesan, Fontina, or even Pepper Jack for a spicy twist.
  • Make sure to drain and dry the corn throughly to prevent excess moisture in your casserole. The dryer you can get it, the better, so excess moisture from the corn doesn’t thin out the sauce.
  • Feeding a big crowd? Double the recipe and bake this in a 9×13-inch pan. You may need to add about 5 minutes to the baking time, but it won’t take too much longer than a single batch.

Storing And Reheating Corn Casserole With Cheese

If you have leftover cheese and corn casserole, transfer it to an airtight container and place it in the fridge uncovered for a few hours until it is fully chilled, then cover it with the lid and keep in the refrigerator up to 3 days. 

Reheat in the oven at 350 degrees F until heated through. You can also microwave individual portions for a quick meal.

Ingredients

  • 2 cans whole kernel sweet corn, drained and patted dry 15 ounces each
  • Nonstick cooking spray
  • 1 tablespoon unsalted butter
  • 1 tablespoon all-purpose flour
  • ½ cup heavy cream
  • ¼ cup whole milk
  • 1 ½ teaspoons granulated sugar
  • ½ teaspoon garlic powder
  • ¼ teaspoon onion powder
  • ¼ teaspoon kosher salt
  • ¼ teaspoon ground black pepper
  • 2 slices Oven Baked Bacon chopped
  • ½ cup shredded Cheddar cheese, divided 2 ounces
  • ½ cup shredded Monterey Jack cheese, divided 2 ounces
  • 1 tablespoon chopped fresh parsley for garnish (optional)

Instructions

  • Drain corn in colander and spread on paper towels (or clean kitchen towel). Pat completely dry with paper towels.
  • Preheat oven to 350 degrees F. Spray 8 x 8-inch casserole dish with cooking spray.
  • Melt butter in large pot over medium heat. Add flour and cook 30 seconds, whisking constantly. While whisking, add cream and then milk in steady stream. Reduce heat to medium-low; add sugar, garlic powder, onion powder, salt and pepper and cook 1 to 2 minutes or until slightly thickened, whisking constantly.  
  • Remove from heat. Stir in bacon, half of Cheddar cheese, half of Monterey Jack cheese, and corn. Mixture will be thick at this point. That's OK – it will thin out as it bakes.
  • Transfer corn mixture to prepared baking dish. Sprinkle remaining Cheddar cheese and Monterey Jack cheese evenly over corn mixture.
  • Transfer to oven and bake 35 to 40 minutes or until casserole is bubbly.
  • If desired, brown cheese under the broiler: preheat broiler to HIGH. Place casserole under broiler and broil 2 to 3 minutes or until lightly charred, watching carefully.
  • Let stand 10 minutes before serving. Garnish with parsley before serving, if desired.
