Ingredients

  • 2 cups fresh or frozen corn kernels (thawed if frozen)
  • 1 can (15 oz) whole kernel corn, drained
  • 1 can (14.75 oz) cream-style corn
  • 1 cup shredded sharp cheddar cheese
  • 1/2 cup sour cream or plain Greek yogurt
  • 1/4 cup unsalted butter, melted
  • 2 large eggs, beaten
  • 1/2 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 cup diced green bell pepper (optional for extra flavor)
  • 1/4 cup finely chopped onion (optional)

Equipment

  • 9×9 inch baking dish
  • Mixing bowls
  • Whisk or fork (to beat eggs)
  • Measuring cups and spoons
  • Spatula or wooden spoon
  • Oven

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your 9×9 inch baking dish with butter or non-stick spray to prevent sticking.
  2. Mix the corns: In a large mixing bowl, combine the fresh or thawed corn kernels, drained whole kernel corn, and cream-style corn. Stir gently to combine.
  3. Add the cheese and dairy: Stir in the shredded cheddar cheese, sour cream (or Greek yogurt), and melted butter. Mix until ingredients are evenly incorporated.
  4. Prepare the wet ingredients: In a small bowl, beat the eggs lightly. Add them to the corn mixture and stir well.
  5. Combine dry ingredients: In another bowl, whisk together the flour, baking powder, salt, and black pepper. If using green bell pepper and onion, stir them into the dry mixture.
  6. Mix dry ingredients into wet: Gradually add the flour mixture to the corn mixture, folding gently until just combined. Be careful not to overmix to keep the casserole light.
  7. Transfer to baking dish: Pour the batter into the prepared baking dish, smoothing the top with a spatula.
  8. Bake: Place the dish in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
  9. Cool slightly and serve: Allow the casserole to cool for 10 minutes before serving to let it set properly.

Tips & Variations

“For extra creaminess, add a half cup of cream cheese or substitute the sour cream with full-fat Greek yogurt for a tangy twist.”

  • Make it vegan: Replace eggs with flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg) and use vegan cheese and sour cream alternatives.
  • Add spice: Mix in 1/2 teaspoon of smoked paprika or chili powder for a smoky kick.
  • Extra veggies: Fold in diced jalapeños, roasted red peppers, or even chopped spinach for added nutrition and flavor.
  • Crunchy topping: Sprinkle crushed crackers or breadcrumbs mixed with a bit of melted butter on top before baking for a crispy crust.
  • Cheese options: Try pepper jack for a spicy twist or mozzarella for a gooey texture.
