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.

Crispy Fish Sandwiches: Frequently Asked Questions

What is Panko?

Panko is a Japanese-style breadcrumb and can be found in the Asian section of your local grocery store. While both panko and breadcrumbs can be used as a coating for fried foods, panko is much more flakier and yields a crunchier, crispier texture.

What can I substitute for buttermilk?

A quick and easy buttermilk substitute is creating your own buttermilk with whole milk and something acidic such as lemon juice or distilled white vinegar.

You can add 1 tablespoon acid (lemon juice or vinegar) to 1 cup milk, letting it stand for 5-10 minutes.
