Oven Baked Cheesy Corn and Spinach Casserole

There’s nothing quite like a warm, cheesy casserole to bring comfort to the dinner table. This Oven Baked Cheesy Corn and Spinach Casserole combines two classic ingredients—sweet corn and fresh spinach—into a creamy, savory bake that’s as easy to prepare as it is delicious. Perfect as a hearty side dish or even a light vegetarian main course, this recipe is ideal for family dinners, holiday gatherings, or potlucks.

The sweetness of corn pairs beautifully with the earthiness of spinach, all tied together with melty cheddar cheese and a rich custard base of eggs and milk. Best of all, it comes together quickly with simple pantry staples.

Ingredients

• 2 cups fresh spinach leaves

• 1 can (15 oz) corn kernels, drained

• 3 large eggs

• 1 cup shredded Cheddar cheese

• ½ cup milk

• ¼ cup all-purpose flour

• ½ teaspoon salt

• ¼ teaspoon black pepper

• ¼ teaspoon garlic powder

• 1 tablespoon butter (for greasing)

Instructions

1. Prep the Oven & Baking Dish

Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish with butter to prevent sticking and add extra flavor.

2. Make the Egg Mixture

In a large mixing bowl, whisk together the eggs, milk, flour, salt, black pepper, and garlic powder until smooth and lump-free. This will form the custard base of your casserole.

3. Combine the Ingredients

Fold in the drained corn kernels, fresh spinach leaves, and half of the shredded Cheddar cheese. Stir gently until evenly combined.

4. Pour & Top

Transfer the mixture into the greased baking dish, spreading it into an even layer. Sprinkle the remaining Cheddar cheese over the top for a golden, cheesy finish.

5. Bake

Place the dish in the preheated oven and bake for 30–35 minutes, or until the top is golden brown and the casserole is fully set in the center.

6. Serve

Allow the casserole to cool for a few minutes before slicing and serving. It pairs wonderfully with roasted meats, grilled chicken, or a fresh green salad.

Tips & Variations

• Cheese Swap: Try mozzarella, Colby Jack, or a sharp white cheddar for different flavor profiles.

• Add Protein: Stir in cooked bacon bits, diced ham, or shredded rotisserie chicken for a heartier dish.

• Make Ahead: Prepare the mixture a few hours ahead, cover, and refrigerate. Bake when ready to serve.

• Spice It Up: Add a pinch of red pepper flakes or diced jalapeños for a subtle kick.
