Are you ready to try something new for dinner? This very best fish recipe ever is bursting with savory flavors and is foolproof. Wow your family tonight!
I was always intimidated by fish until I stumbled upon this amazing recipe, and I have been meaning to share it for ages. I got the original version from my dear friend, Jenny, during a mom’s-night-out recipe swap back when we both lived in Seattle. We were so chatty that night that I only ended up writing down two recipes, but this was one of them.
In the years since, I have tweaked it just a bit. It is one of my family’s very favorite meals and it is also a fantastic—and super easy—dish to serve guests (provided they eat seafood).
The really great thing about this recipe is that it works with pretty much any type of fish or seafood. The original recipe called for halibut, which I love, but it’s very hard to get here in Florida. I have used tilapia, mahi-mahi, salmon, flounder, cod and shrimp with this recipe, and they have all turned out wonderful. Another easy fish recipe that has become a family favorite during the warmer months is this Fish Taco recipe.

This was super simple and really good! I made it before and did not read all the instructions. So, the first time, I dried the fillets and used the mayo/butter/parm mixture as a coating – both sides. I also flipped half way to try and get the coating to crisp/brown just a bit on both sides. This time, I did as suggested – both ways work and both ways were truly tasty!! Thanks for a lovely, easy recipe for fish!
This was amazing! I have made it before with tilapia and last night tried it with salmon. I don’t know how it happened, but there was about half a filet of salmon left over, so today, I flaked it into a bowl with all the rest of the creamy cheese mixture from the baking dish, added a little more mayonnaise, a little sour cream and a squeeze of lemon. It became the Best Ever Salmon Dip Recipe!
This is a GREAT Recipe!! We love it! I never cared for fish before. I leave out the onions. I would serve this to company!! I usually serve rice, or baked potato with it and a vegetable. Yummy!!
Really easy and yummy. I didn’t have any green onions but it was still good. Leftovers will be fish tacos for tomorrow
It looks so delicious and mouth-watering. Got to try it as soon as possible.
I’ve made this several times over the last couple of years and it’s always a hit with my family!
Yay!! So glad you and family like this recipe. Thanks for letting us know. 🙂
