Rich in flavor and easy to prepare, this dish combines tender spinach with a smooth, cheesy béchamel sauce, seasoned to perfection.

Instructions:

1. Prepare Spinach:
- Begin by thawing the frozen spinach. After it's thawed, drain and squeeze out as much excess water as possible. Set aside.
2. Preheat Oven:
- Preheat your oven to 375°F (190°C).
3. Cook Onions:
- In a large saucepan, melt the butter over medium heat.
- Add the finely chopped onions and cook until they become translucent, about 5-7 minutes.
4. Make Roux:
- Add the all-purpose flour to the saucepan with the cooked onions, stirring constantly to form a smooth paste. Cook for about 2-3 minutes to remove any raw flour taste, but make sure it doesn't brown.
5. Create Béchamel Sauce:
- Slowly pour in the milk, whisking continuously to avoid lumps. Continue to cook and whisk until the sauce thickens and coats the back of a spoon, about 5-7 minutes.
- Stir in the ground nutmeg, salt, and black pepper to season the sauce.
6. Combine Spinach and Sauce:
- Add the drained spinach to the saucepan and stir well to combine. Make sure the spinach is evenly distributed throughout the creamy sauce.
7. Transfer to Baking Dish:
- Pour the spinach mixture into a greased baking dish, spreading it out evenly.
8. Add Cheese:
- Sprinkle the grated parmesan cheese evenly over the top of the spinach mixture.
- Finish with a layer of grated swiss cheese over the parmesan.
9. Bake Gratin:
- Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the top is golden brown and bubbly.
10. Serve:
- Remove from the oven and let it sit for a few minutes before serving. Enjoy your delicious Spinach and Parmesan Gratin as a wonderful side dish or a main course.

With its creamy texture and cheesy goodness, this spinach and parmesan gratin is sure to become a family favorite.

Spinach and parmesan gratin FAQ:

How long should I bake the spinach and parmesan gratin?

Bake the gratin in a preheated oven at 375°F (190°C) for about 25-30 minutes, or until the top is golden brown and bubbly.

What pan size is recommended for this gratin?

A standard 9x13 inch baking dish works well for this recipe, allowing enough space for the spinach and cheese mixture to spread evenly.

Can I use fresh spinach instead of frozen?

Yes, you can use fresh spinach. You would need about 1 pound of fresh spinach. Cook it down to reduce moisture, then proceed with the recipe as directed.

How do I store leftovers of the spinach and parmesan gratin?

Cool the gratin to room temperature, then store in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven until warmed through.

What can I use as a substitute for Swiss cheese?

If you don't have Swiss cheese, you can substitute with Gouda or Gruyère for a similar flavor and melting quality.

Cooking Tips:

- Feel free to add herbs like thyme or basil for an extra layer of flavor.

- If you don't have Swiss cheese, Gruyère or mozzarella can be good substitutes.

- To create a crispy topping, you can sprinkle some breadcrumbs mixed with melted butter over the gratin before baking.
