Ingredients
- 3 tbsp whipped butter (or 2 tbsp regular butter)
- 1 cup finely chopped onion
- 1/4 tsp freshly grated nutmeg
- 1/4 cup all-purpose flour (or gluten-free flour mix)
- 3 cups 2% milk
- 3 lbs frozen chopped spinach, defrosted (about 3 16-oz packages)
- 3/4 cup Parmesan cheese, freshly grated
- 1 tbsp kosher salt (adjust if using a different salt)
- 1/2 tsp freshly ground black pepper
- 1/2 cup Gruyere cheese, shredded (Swiss works too)
Instructions
- Preheat oven: Set to 425°F.
- Cook onions: In a heavy-bottomed pan, melt butter over medium heat. Add onions and sauté until translucent, about 10–12 minutes.
- Make roux: Stir in flour and nutmeg; cook 2 minutes.
- Add milk: Pour in milk, cooking and stirring until thickened, about 5–7 minutes.
- Prepare spinach: Squeeze out as much liquid as possible from the spinach. Add it to the milk mixture.
- Add cheese & seasoning: Mix in 1/2 cup Parmesan. Season with salt and pepper to taste.
- Bake: Transfer spinach mixture to a large baking dish. Sprinkle remaining 1/4 cup Parmesan and all Gruyere on top. Bake 20 minutes until hot and bubbly. Serve immediately.
Tips & Variations
- Fresh Spinach: Use 1.5–2 lbs; sauté lightly in olive oil and squeeze out liquid.
- Cheese Alternatives: Swiss or mozzarella can replace Gruyere.
- Less Cheese: Skip the melted top layer for a lighter creamed spinach.
- Gluten-Free: Use a gluten-free flour mix like Cup4Cup.
- Make Ahead: Prepare a day in advance; cover and refrigerate. Bake when needed.
Storage
- Refrigerate leftovers in an airtight container up to 4 days; reheat in microwave.
- Freezing not recommended due to dairy content.
