Oh-so-crisp fish sandwiches with melted cheese, soft brioche buns and homemade tartar sauce! Seriously so so good.
This right here is a classic fish sandwich. There’s no frills, no fuss. All you need is a simple coating, yielding the lightest, crispiest exterior (thank you to Panko breadcrumbs), some good old fashioned American cheese slices, soft, toasted brioche buns and a homemade tartar sauce.
Fish-wise, I prefer orange roughy or petrale sole fish filets but you can also use flounder or cod. You can also add in a slaw, although personally, I think simple is best here. And this homemade tartar sauce is truly all you need to round out this perfect sandwich (and don’t worry – it doesn’t require too many ingredients).
You can keep your fish warm and cozy in a 200 degree F oven for up to 30 min before assembling all your sammies. For sides, you can serve with fries or chips and some ice cold beers for a well rounded out meal.

I made this in the air fryer (390 for 10 minutes give or take) and the fish turned out great! I added some leftover shredded cabbage and put the mayo, sriracha, and pickles on the bun.
I made this recipe tonight. I had some buttermilk I wanted to use up. It was fantastic. Easy instructions. Not too many ingredients and very delicious. I used cod fillet and I even made some shrimp. This recipe is a keeper!
Everything you make looks amazing and I want to try. Just wondering if you would be able to post the calories per serving. I know that is extra work, just looking for recipes under a certain calorie amount. Thanks!
I absolutely love when you say to add fries, chips, and beer for a well-rounded meal – you and I could be best friends!!!
Is there a way to use an air fryer? I’m afraid of large amounts of hot oil.
