Ingredients
- 2 tablespoons butter
- 1 small onion finely chopped
- 2 cloves garlic minced
- 2 tablespoons all-purpose flour
- 1 ½ cups whole milk
- ½ cup heavy cream
- ½ teaspoon salt
- ¼ teaspoon freshly ground black pepper
- ¼ teaspoon nutmeg
- 1 cup Gruyère cheese shredded, or Swiss
- ½ cup Parmesan cheese grated, divided
- 20 ounces frozen chopped spinach thawed and very well squeezed dry
- ½ cup panko breadcrumbs
- 1 tablespoon olive oil
Instructions
- Preheat oven to 400 °F (200 °C). Lightly butter or spray a medium baking dish.
- In a large skillet, melt 2 tablespoons butter over medium heat. Add 1 finely chopped onion and cook for 3 to 4 minutes until softened. Stir in 2 minced cloves of garlic and cook 30 seconds more.
- Sprinkle in 2 tablespoons flour and whisk for 1 minute. Gradually pour in 1 ½ cups milk, whisking until smooth. Add ½ cup heavy cream, ½ teaspoon salt, ¼ teaspoon pepper, and ¼ teaspoon nutmeg. Cook 3 to 4 minutes until slightly thickened.
- Stir in 1 cup shredded Gruyère and ¼ cup grated Parmesan until melted and creamy.
- Fold in 20 ounces chopped spinach (squeezed dry) until fully combined. Taste and adjust seasoning if needed.
- Transfer the mixture to the prepared baking dish. In a small bowl, combine ½ cup panko breadcrumbs, ¼ cup Parmesan, and 1 tablespoon olive oil. Sprinkle evenly over the top.
- Place in the oven for 20 to 25 minutes, or until the topping is golden brown and the edges are bubbling.
Notes
- Squeeze the spinach thoroughly. Any moisture left behind will thin the sauce.
- Freshly grated Gruyère and Parmesan melt smoother and give better flavor.
- Season the cream mixture to taste before adding the spinach.
- Add a pinch more nutmeg if you like a warmer, sweeter finish.
- If the topping browns too quickly, cover lightly with foil during baking.
- Leftovers reheat well in the oven or microwave. It is great with eggs the next morning.
