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.

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.

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:
