Cheesy Spinach Casserole

Martha Stewart’s Spinach Cheese Puff; a casserole made with spinach, Gruyere cheese, half & half and eggs. Baked to a bubbly golden brown, this spinach side dish will go great alongside just about anything.

I’m not sure why Martha calls it a puff because there’s nothing puffy about it. . . it’s dense, creamy and rich without being overly so.

It’s a cinch to throw together with some planning. The recipe calls for thawed, frozen, chopped spinach with the water squeezed out of it. It’s best to do it overnight in a colander placed over a bowl in your refrigerator, or the morning of, as it does take a few hours for the spinach to thaw.

You can use any good melting cheese – I used mozzarella. This isn’t super cheesy so if that’s what you’re looking for toss in some extra.
