Ingredients

For the Casserole

4 cups corn kernels (fresh, frozen, or canned and drained)
4 cups fresh spinach, roughly chopped
1 tablespoon olive oil
1 small onion, finely diced
2 cloves garlic, minced
1 cup sour cream
1 cup shredded cheddar cheese
1 cup shredded mozzarella cheese
2 large eggs, lightly beaten
½ cup milk
½ teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika

For the Topping

½ cup shredded cheddar cheese
¼ cup grated Parmesan cheese
½ cup breadcrumbs
1 tablespoon melted butter

Step-by-Step Instructions

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

Step 2: Cook the Vegetables

Heat olive oil in a skillet over medium heat. Add the onion and cook for 3–4 minutes until softened. Stir in the garlic and cook for another minute. Add the spinach and cook until just wilted. Remove from heat and allow to cool slightly.

Step 3: Make the Filling

In a large mixing bowl, combine the corn, cooked spinach mixture, sour cream, cheddar cheese, mozzarella cheese, eggs, milk, salt, black pepper, and paprika. Stir until everything is evenly mixed.

Step 4: Assemble the Casserole

Spread the mixture evenly into the prepared baking dish.

Step 5: Prepare the Topping

In a small bowl, combine breadcrumbs, Parmesan cheese, shredded cheddar cheese, and melted butter. Sprinkle evenly over the casserole.

Step 6: Bake

Bake for 30–35 minutes, or until the casserole is hot, bubbly, and golden brown on top.

Step 7: Rest and Serve

Allow the casserole to rest for 5–10 minutes before serving. This helps it set and makes it easier to slice.

Tips & Notes

Frozen spinach can be used instead of fresh; thaw and squeeze out excess moisture first.
Sharp cheddar provides the best cheesy flavor.
Add diced jalapeños for a spicy kick.
For a heartier casserole, stir in cooked chicken or turkey.
Let the casserole rest before serving for cleaner portions.
Store leftovers in the refrigerator for up to 4 days.
