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.

    This looks amazing, Reeni!  And with healthy things like spinach and eggs, I’m thinking it would even be perfect for a holiday brunch!  ;)

    This is a delicious way to eat your vegetables! Thank you for whetting my appetite. Now I don’t want to go to work tomorrow, I just want to get in the kitchen and cook! I hope you have a blessed week, my friend!

    I love this dish.  

    I am not online Saturdays and Sunday, I am busy doing lesson plans and marking papers.  I usually remember this linky on Tuesdays when it is already closed.  I want to participate especially with sides.  Since we have cut back on our meat, I have been making some really good ones.

    I would tell you that I will remember, this week, but it is Chanukah and I probably will not get online for much time.

    I am thinking of you.  Happy Holidays.     Chaya

      No  worries Chaya! I am thinking of moving it to another day or maybe I will just leave the linky open longer. Not many people seem to be participating on Saturday. Enjoy your holiday! xoxo

      No it’s not Jenn! Did you squeeze your spinach dry? It probably released some water as it cooked. You can try cooking it a little longer or it may set up a little as it cools down. Thanks for making it!
