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

    Thinking about subbing greek yogurt for mayo or uaing less mayo and more sour cream… I’m not a huge mayo fan. Can’t wait to try

      • Alyona’s Cooking

      I wouldn’t really say theres a harsh distinctive mayonnaise taste as the sour cream and mayo are a 1 to 1 ratio in this recipe. After baking Im not even sure if you will be able to detect any mayonnaise. But if you strongly prefer to substitute, I would probably just use less of mayo instead of omitting it altogether as sour cream and greek yogurt are both dairy products. Mayonnaise does contain some grease so the results might be slightly different if substituting with something else.

        I love this recipe just as is. What about using the mayo & sour cream & spices as a deviled egg recipe? Please let me know what you think? Sincerely Donna Williams.

          • Alyona’s Cooking

          I’m not sure about this being a filling inside eggs, but perhaps a mustard or more of a vinegary combo would fit better to devilled eggs.

          • Domna

          I used the seasoning part with a bit of mustard and mayo as a deviled egg filling & everyone loved it. Just added a nice zippy flavor.
          The Tilapia & spinach is a new favorite in our house. Thank you! Donna.

            You are welcome, Donna.

      What can u substitute for the Adobe and old bay??

        • Alyona’s Cooking

        Try 1/8 tsp garlic powder, 1/4 tsp salt, pinch of oregano, 1/4 tsp black pepper and 1/4 tsp paprika for the Adobe & Old Bay seasoning. Turmeric and celery salt could be additions just use at your discretion.

      Made this dish tonight with some slight modifications due to a lack of certain items. It was delicious. Even my husband had seconds. Thank you for sharing.

        • Alyona’s Cooking

        Thank you for the kind feedback, sue

      • Barb Coulter

      Good recipe. Changed it up a bit by substituting Sriracha mayo for regular. Didn’t have Old Bay or Adobo seasoning so added Korean red pepper seasoning (Shichimi Togarashi) and capers. We enjoy highly seasoned foods and this was really great.

        • Alyona’s Cooking

        Thank you for the kind feedback, Barb.

      • Katy | Her Cup of Joy

      Wow this recipe sounds so delicious and healthy with the addition of spinach!

        • Alyona’s Cooking

        Thank you Katy:)

        • Audrey

        My husband just said this is great and with spinach no less

        • Kat

        Great recipe. I used cod fish instead and under spinach added veggie rice type of mix creation. Came out delicious
