How to Make Spinach Casserole
- Cook garlic in butter, whisk in cream cheese and heavy cream until the sauce is smooth.
- Stir in spinach, Gruyere, half the cheddar, and seasonings.
- Transfer mixture to baking dish and top with remaining cheese and breadcrumbs.
- Bake until the cheese is golden and bubbly.
Spinach Casserole Secrets
- It is important to remove as much water as possible from the spinach so the dish doesn’t get watery. Place frozen spinach in a strainer to drain while you prep the rest of the recipe, then press any remaining liquid out. Alternatively spread it on a clean dish towel, roll the towel up, and twist it to squeeze the liquid out.
- Allow the casserole to rest for a few minutes after baking so it can firm up a bit.

From Oven to Fridge
- Refrigerate spinach casserole in a covered container for up to 4 days.
- Reheat leftovers in the microwave or in a low temperature oven covered with foil, until warmed through.
- Freeze portions in zippered bags for up to 2 months, and be sure to label with the date. Thaw in the refrigerator, drain, and reheat as desired.
