Creamy Spinach Gratin

Teresa

2013 – Gluten Free Living

Creamy Spinach Gratin is so mouthwatering. I’ve finally found an amazing spinach casserole recipe that really tastes the way I want it to taste! I’ve been hunting for years for just the right recipe. I wanted a superb “go-to recipe” for spinach. I think it’s safe to say I’ve finally found one I really LOVE! Creamy Spinach Gratin is S-P-E-C-T-A-C-U-L-A-R!!!

There’s lots of spinach in a really thick creamy sauce. I used half-and-half, heavy whipping cream, Parmesan cheese and Gruyere cheese. Wow did this casserole burst with flavor. Creamy Spinach Gratin also has onion, leeks and garlic which add delicious, savory flavors as well. I made this recipe using gluten free flour, too, so it’s gluten free for those with gluten intolerance. (But you can always use regular flour if you don’t have gluten allergies). Creamy Spinach Gratin is irresistible, sumptuous, heavenly!

I was looking through my Pinterest boards a couple of weeks ago. I was trying to come up with some ideas for side dishes for a large dinner party we had a week and a half ago. I had seen this recipe and pinned it so I could go back and look it over more carefully.

All I can say is this recipe is special. Even all my guests thought it was a wonderfully tasting spinach dish. While this dish does have several steps it’s not overly difficult. The hardest thing is squeezing out all the water from the spinach. No kidding.

It probably took me every bit of 10 minutes pressing the spinach in order to get all the excess moisture out it. I used a potato masher. This is a super important step. Otherwise, the recipe will not set up and will be soupy. Anyway, I am so glad I found this recipe. I think you will be too if you try it as well.

Creamy Spinach Gratin would be a great casserole for the holidays. You can do as I did and make it up in advance, refrigerate it, and then bake it later in the day when you’re ready to cook everything. I’m sure you could also heat it up in the crockpot if your oven is too full of other things.

If you’re looking for a “to die for” spinach recipe, then Creamy Spinach Gratin should be included in that quest. It’s rich, creamy, cheesy, with one of the best combinations of flavors, textures, and eye appeal I’ve ever found in a spinach recipe before. I loved it and our guests raved over it! Yay.

I initially posted this recipe in October 2013. I recently remade this recipe twice (March 2020) during the coronavirus outbreak. I made it once when we had my son and his wife over for lunch on Sunday. I made it the second time for just my husband and me. The first time I served it with Baked Parmesan Chicken and my daughter-in-law brought a salad. The second time I served it with Grilled Peppered Steaks. It’s really a fantastic side dish for any kind of entree.

I used these ingredients.

Saute onions and leeks in a stick of butter over medium heat for about 5 minutes.  Stir occasionally.

Add the garlic and cook until fragrant, but not more than a minute or two or it will scorch and become bitter.

Thaw spinach. Squeeze-squeeze-squeeze until as much moisture as possible is released from the spinach. I found it easiest to use a potato masher to press out the water.

Cover with foil. Bake at 350 for about 30-40 minutes or until bubbly and heated through. You will probably need to tent the foil after 20-25 minutes so it doesn’t stick to the cheese.
