Ingredients
2 (10-ounce) packages frozen chopped spinach, thawed and drained
1/4 cup unsalted butter
1 small yellow onion, finely chopped
2 cloves garlic, minced
2 tablespoons all-purpose flour
1 1/2 cups whole milk
1/2 cup heavy cream
1/2 teaspoon salt
1/4 teaspoon ground black pepper
1/4 teaspoon ground nutmeg (optional)
1 1/2 cups shredded sharp cheddar cheese
1/2 cup grated Parmesan cheese
1 cup seasoned breadcrumbs (or panko)
Cooking spray or butter for greasing the baking dish
Instructions
1. Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. In a large skillet over medium heat, melt the butter. Add the chopped onion and cook until translucent, about 3–4 minutes. Add minced garlic and cook for 30 seconds.
3. Sprinkle in the flour and stir constantly for 1 minute to make a roux.
4. Gradually whisk in the milk and then the heavy cream. Stir until the sauce thickens slightly, about 4–5 minutes.
5. Season with salt, pepper, and nutmeg if using. Reduce heat and stir in cheddar and half the Parmesan until smooth.
6. Add the drained spinach and stir until fully combined and creamy.
7. Transfer the mixture to the prepared baking dish and spread evenly. Top with remaining Parmesan and breadcrumbs.
8. Bake uncovered for 25–30 minutes until bubbly and golden.
9. Let rest for 5–10 minutes before serving for best texture and flavor.
Notes
Be sure to squeeze all excess water from the spinach to avoid a watery casserole.
Letting the casserole rest after baking helps it set for easier serving.
Swap cheddar with Gruyère or mozzarella for a fun flavor twist.
