7 Steps to Make Oven Baked Cheesy Corn and Spinach Casserole

Step 1 – Preheat the Oven

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

Step 2 – Sauté the Aromatics

In a skillet, melt the butter over medium heat. Add diced onion and garlic, sautéing until soft and fragrant.

Step 3 – Add Spinach and Corn

Toss in the chopped spinach and cook until wilted. Stir in the sweet corn kernels and let everything blend for 2–3 minutes.

Step 4 – Make the Cheese Sauce

In a bowl, whisk together Cheddar cheese, mozzarella cheese, and heavy cream. Season with salt and pepper.

Step 5 – Layer the Casserole

Spread half of the corn-spinach mixture into the baking dish. Pour half of the cheese sauce on top. Repeat with the remaining layers.

Step 6 – Add Breadcrumbs and Bake

Sprinkle breadcrumbs over the casserole. Cover with foil and bake for 20 minutes. Remove foil and bake an additional 10–15 minutes until golden and bubbly.

Step 7 – Rest and Serve

Let the casserole cool slightly before serving. Garnish with extra cheese or herbs if desired.
