Oven Baked Cheesy Corn and Spinach Casserole

Ingredients:

Step-By-Step Directions:

1. Preheat and Prepare: Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish with 1 tablespoon butter to ensure nothing sticks during baking.

2. Whisk the Base: In a large mixing bowl, whisk together the 3 large eggs, 1/2 cup milk, 1/4 cup all-purpose flour, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1/4 teaspoon garlic powder until the mixture is completely smooth and free of lumpiness.

3. Mix the Filling: Stir in the 1/15 oz can of drained corn kernels, 2 cups of fresh spinach leaves, and half of the shredded cheddar cheese until everything is evenly coated in the egg mixture.

4. Transfer to Dish: Pour the mixture into the prepared baking dish, spreading it evenly across the bottom so it cooks uniformly.

5. Top with Cheese: Sprinkle the remaining half of the cheddar cheese evenly over the top of the casserole to form a rich upper layer.

6. Bake to Golden: Bake in the preheated oven for 30 to 35 minutes, or until the top is golden brown, the cheese is beautifully melted, and the center of the casserole is completely set.

7. Cool and Serve: Let it cool for a few minutes on the counter before serving so the casserole can firm up slightly, making it much easier to scoop and plate cleanly.
