1/4 cup all-purpose flour – Helps thicken the sauce for that ultimate creamy texture.

1/4 tsp fresh grated nutmeg – Adds a warm, aromatic flavor that complements the spinach beautifully.

3 cups 2% milk – The main liquid for the sauce, providing creaminess and richness.

3 lbs frozen chopped spinach, defrosted – This gives you a hearty, satisfying green element that’s both nutritious and flavorful.

3/4 cup Parmesan cheese, freshly grated – Contributes a salty, nutty flavor that enhances the gratin’s richness.

1 tbsp kosher salt – Essential for bringing out all the other flavors.

How to Make Ina Garten Spinach Gratin

Follow these simple steps to prepare this delicious Ina Garten Spinach Gratin:

Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). This temperature is key to achieving that glorious golden brown crust on top that will make your mouth water just thinking about it.

Step 2: Sauté the Onions
In a heavy-bottomed pan, melt the whipped butter over medium heat. Once it’s melted and slightly bubbling, add the finely chopped onion. Sauté them for about 10 to 12 minutes until they’re translucent and fragrant, making your kitchen smell just divine.

Step 3: Create the Roux
Add the all-purpose flour and freshly grated nutmeg to the pan with the onions. Cook this mixture for an additional 2 minutes, stirring occasionally. This step is essential for creating a thick, creamy sauce to envelop your spinach.

Step 4: Thicken the Sauce
Gradually whisk in the milk, stirring constantly until the mixture thickens, roughly 5 to 7 minutes. You’ll know it’s ready when it coats the back of a spoon, thick and smooth like a soft hug.

Step 5: Add the Spinach and Cheese
Once the sauce is thickened, squeeze as much liquid as you can from the defrosted spinach and fold it into the sauce. Next, add in 1/2 cup of the Parmesan cheese, mixing everything well. Season with kosher salt and freshly ground black pepper to your liking.

Step 6: Assemble and Bake
Transfer the delicious spinach mixture into a large baking dish. Top it off with the remaining 1/4 cup of Parmesan cheese and the Gruyere cheese, distributing evenly. Bake for 20 minutes until hot and bubbly, and that top is a beautiful golden brown that you can’t help but admire.

Now, you’re ready to serve this delightful Ina Garten Spinach Gratin!
