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

    Very delicious recipe‼️ Seasoned the fish with other seasonings instead of the sauce and didn’t make it as creamy. Looking forward to making it again. Truly enjoyed by family❣️Thanks

      I agree there’s much flavor going on, Meghan! Have you tried the chicken version? It’s even more simpler but yet so much flavor!

    I loved it, and didn’t change a thing

      • Alyona’s Cooking

      I’m glad to hear, Randle! Thank you for the feedback!

    • Lisa Diaz

    Super yummy recipe! The bag of tilapia I used only had 4 pieces of fish in it. Instead of mayo, I used 1 whole avocado and I didn’t use any black pepper or salt (the adobo seasoning recipe I used had both salt & pepper). Will definitely be making this again!

      • Alyona’s Cooking

      What a healthy alternative using avocado for the mayo, Lisa!

    • Katrin Gruzmark

    came out amazing! did it with cod it it was amazing.
    a second time i added white button mushrooms beneath the fish and it came out good as well!

      • Alyona’s Cooking

      Thank you for the feedback, Katrin!
