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 recipe seemed too simple to be seriously delicious – but it’s seriously delicious! I didn’t have a couple of the ingredients so had to improvise. It *still* turned out amazing.
Instead of lemon juice, 1 T. Dijon mustard worked great. It also compensated for not having tabasco sauce, this time. Hopefully I’ll have it handy for next time – and there WILL be a next time.
We are Floridians and know good seafood. This was restaurant quality.
I’m on a Keto diet and I don’t see the nutrition breakdown.
I made this for dinner tonight and talk about good!!! I didn’t have any lemon juice, so I added lemon pepper seasoning and used yellow onion diced. I must say that it was sooo delicious!! I also used parmesan cheese in the green can. Thank you so much for posting this!! I can’t wait to try this again with the ingredients you included in this recipe.
When you broil the fish, do you keep the oven rack in the middle or do you move it up closer to the coils? My broil setting gives me temp options, (500 degrees is high) am I going for a lower temp or the higher temp? Also, I’ve never cooked with fish, so I don’t know how it fares as a leftover dish. It’s just me and my husband so I often have leftovers from recipes I make. Has anyone tried this reheated? Thanks! Looks amazing!
This is by far the best!! This comes from someone who thinks fish is boring. Thanks!!!
