NOTE: Use as much spinach as you can pack into your baking dish because spinach does shrink quite a bit.

1. First, pack spinach onto the bottom of a baking dish. Top with butter slices and layer the fish fillets over the top

    Can you use frozen spinach instead of fresh?

    • A Reed

    This recipe is both super easy and delicious! I tried it once with thin cut chicken breasts and it was just as wonderful! I also add a few extras sometimes, like mushrooms and onions, to give it even more substance. This has been added to my regular menu rotation.

      • Alyona Demyanchuk

      That is wonderful!

    Love this recipe. It is easy and delicious. I did spray the spinach with olive oil spray and left out the butter. Sprinkled extra grated Parmesan on top. Served it over brown rice. Yummy!

      • Alyona Demyanchuk

      Sounds delish, Cheryl!

    • Jennifer

    This was really good! I used Mahi Mahi as that’s what I had. Aside from adding Panko on top, I followed the recipe as written. The panko added a nice crunch, so I’d do it again. Thanks!

      • Alyona Demyanchuk

      Good to know it works with other fish!

    • Marilyn

    I cut the sauce in half and spread it around on top. I still used the same amount of seasonings and cheese. We felt like we were dining in the FINEST restaurant. Absolutely DELICIOUS!!!
    Only reason I made half the cheesy sauce is, unfortunately, lactose issues. Surprised it was still plenty and creamy
