Key Ingredients and Substitutions

Potatoes

Potatoes are the star of this recipe, providing a creamy and tender base. You can use Yukon Gold or russet potatoes for their creamy texture and ability to hold their shape when cooked.

Spinach

Fresh spinach adds a nutritious and flavorful element to the gratin. You can use frozen spinach, but be sure to thaw and drain it well to remove excess moisture.

Heavy Cream

Heavy cream adds richness and creaminess to the sauce. You can substitute it with half-and-half or milk for a lighter version, but keep in mind that the texture and flavor may vary.

Cheese

Gruyère cheese adds a rich, nutty flavor to the gratin. You can substitute it with other types of cheese like cheddar, Gouda, or Swiss cheese for a different flavor profile. Parmesan cheese provides a salty and nutty flavor that complements the Gruyère.

How to Make Creamy Potato and Spinach Gratin (Step-by-Step)

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). This step ensures that the oven is hot and ready for baking the gratin.

Step 2: Sauté the Onions and Garlic

Melt the Butter: In a large skillet, melt the butter over medium heat.
Add the Onions: Add the chopped onions and sauté until translucent.
Add the Garlic: Add the minced garlic and cook for another minute. This step creates a rich and flavorful base for the gratin.

Step 3: Wilt the Spinach

Add the fresh spinach to the skillet and cook until it wilts, about 2-3 minutes. Remove from heat and set aside. This step ensures that the spinach is fully wilted and ready to be added to the gratin.

Step 4: Prepare the Cream Sauce

In a saucepan, combine the heavy cream, milk, salt, and black pepper. Heat over medium heat until the mixture just begins to simmer. Do not let it boil. This step creates a rich and creamy base for the sauce.

Step 5: Assemble the Gratin

In a greased 9×13-inch baking dish, layer the sliced potatoes, wilted spinach, and cream sauce. Sprinkle the grated Gruyère and Parmesan cheeses over the top. This step ensures that the gratin is evenly layered and ready to be baked.

Step 6: Bake the Gratin

Cover and Bake: Cover the dish with aluminum foil and bake for 30 minutes.
Uncover and Bake: Remove the foil and bake for an additional 15-20 minutes, or until the top is golden and bubbly. This step ensures that the gratin is fully cooked and achieves a perfect golden and bubbly texture.

Step 7: Rest and Serve

Let the gratin rest for 5-10 minutes before serving. This step allows the flavors to settle and makes it easier to serve. This step adds a delightful contrast of flavors and textures, making the gratin even more enjoyable.
