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.

Making for a second time tonight. Great recipe
Can I use the powdered parmesan cheese since that is what I have or does it need to be the shredded kind? I am going to try this tonight. My husband and I like fish but my boys hate it. Hoping they will eat this.
You can try it with what you have on hand. It just might not have the full flavor of shredded Parmesan.
Do you think it would taste the same if I halved the recipe? We won’t eat 2 lbs of fish and my husband won’t eat leftover seafood…..
I would decrease the rest of the ingredients! 🙂
I’m looking fit a great fish recipe for my whole family. Is this spicy? Hoping to try it tonight. Thanks!
No, this recipe is not spicy. I hope your family enjoys it. 😉
::: DISCLAIMER:::
I absolutely can’t stand Hellman’s style mayo, the lemon in it smells and tastes horrid to me; and I’m actually not a mayo eater in general, we’re a Whip family.
That being said…
I gave this a whirl using Heinz mayo. For anyone wondering what the dish tastes like: It tastes like fish baked with a cheesy Lemon Dill Tartar Sauce.
I enjoyed it much more than I thought I would by the smell after I mixed the lemon juice into the mayo. But it will definitely need some tweaking to suit our family’s tastes if I make it again.
Like cutting the lemon in half, tripling the hot sauce, and reducing the butter a bit.
One thing I added this time that was a definite bonus was Capers and Pimentos, they worked VERY well in it and made the presentation very lovely.
