Instructions
 

Preheat and Prep

  • Preheat oven to 350°F (175°C). Grease a deep baking dish with butter.

Prepare the Vegetables

  • Blanch the spinach and roughly chop. Cook sweet corn until tender. Peel and thinly slice the potatoes; place in salted water to prevent browning.

Sauté Spinach and Corn

  • Melt 2 tablespoons of butter in a saucepan over medium heat. Add half the minced garlic and sauté for one minute. Add the chopped onion and cook until softened.
  • Stir in the spinach and corn; cook for 4-5 minutes until heated through. Set aside.

Make the White Sauce

  • In a clean saucepan, melt the remaining 2 tablespoons of butter. Add the remaining minced garlic and cook for one minute.
  • Whisk in the flour and cook for one minute, stirring constantly. Gradually whisk in the milk, ensuring no lumps form.
  • Bring to a simmer, stirring constantly, until the sauce thickens (about 5 minutes). Season with salt and pepper. Stir in the Gruyere cheese until melted and smooth.

Assemble and Bake

  • In the prepared baking dish, layer half of the spinach and corn mixture. Pour half of the white sauce over the vegetables. Arrange the potato slices over the sauce.
  • Top with the remaining spinach and corn mixture, and pour the remaining white sauce over all. Sprinkle with the mozzarella cheese.
  • Cover the baking dish with foil and bake for 20 minutes.
  • Remove the foil and bake for another 20-25 minutes, or until the top is golden brown and bubbly.

Serve

  • Let cool slightly before serving. Serve hot as a main course or a side dish. Enjoy!

Recipe Notes

Expert Tips for the Perfect Spinach and Corn Au Gratin

  • For extra flavor, add a pinch of nutmeg to the white sauce.
  • If using frozen corn, thaw and drain it thoroughly before adding it to the spinach mixture.
  • To prevent the potatoes from becoming soggy, ensure the white sauce is thickened before layering.
  • For a richer flavor, use a combination of cheeses, such as Gruyere, Fontina, and Parmesan.
