Spinach Gratin
From McGough's Recipes
Ingredients
- 3 tbsp whipped butter, I used Land O Lakes
- 1 cup finely chopped onion
- 1/4 cup flour, use Gluten free AP flour for GF
- 1/4 tsp fresh grated nutmeg
- 3 cups 2% milk
- 3 lbs frozen chopped spinach, defrosted, I used 3 16-oz packages
- 3/4 cup freshly grated Parmesan cheese
- 1 tbsp kosher salt
- 1/2 tsp freshly ground black pepper
- 1/2 cup shredded Swiss or Gruyere cheese
Instructions
- Preheat the oven to 425F°.
- In a heavy-bottomed saute pan melt the butter over medium heat. Add the onions and sauté until translucent, about 10 - 12 minutes.
- Add the flour and nutmeg; cook 2 more minutes, stirring occasionally.
- Add the milk and cook until thickened, about 5 - 7 minutes.
- Squeeze as much liquid as possible from the spinach and add the spinach to the sauce.
- Add 1/2 cup of the Parmesan cheese and mix well. Season to taste, with salt and pepper.
- Transfer the spinach to a large baking dish and sprinkle the remaining 1/4 cup Parmesan and the Swiss cheese on top. Bake for 20 minutes until hot and bubbly. Serve hot.
