How to Make Spinach Gratin
-
Prepare the spinach
Sauté fresh spinach (or thaw frozen spinach) until wilted, then squeeze out any excess liquid. This step prevents a watery gratin. -
Make the sauce
In a saucepan, melt butter and whisk in flour to form a roux. Slowly add milk or cream, stirring until thickened. Season with garlic, onion, salt, pepper, and a pinch of nutmeg. -
Combine and layer
Fold the spinach into the creamy sauce and transfer the mixture into a buttered baking dish. -
Top and bake
Sprinkle generously with cheese and breadcrumbs, then bake until golden and bubbling.
Tips for the Perfect Spinach Gratin
-
Use fresh spinach for a brighter flavor, but frozen works if drained well.
-
Gruyère is the classic choice for gratins, but Parmesan or mozzarella can be used for variation.
-
Make it ahead – Assemble the gratin a day in advance and bake just before serving.
-
Add-ons – Mushrooms, caramelized onions, or a sprinkle of crispy bacon can elevate the dish further.
Serving Suggestions
