Air Fryer Fish Sandwich

by Karly

Our AIR FRYER FISH SANDWICH is crispy outside, tender inside, and loaded with tartar sauce and pickles. We used flounder, but you can use almost any white fish for a great sandwich!

Fish sandwiches are a total thing right? You either love them or hate them.

I am in camp love them! When paired with a good tartar sauce and a sweet bun they are so dang good!

The air fryer is a great way to cook your fish fillets and can make that crispy fish sandwich so quickly!

Crispy breading, tender and moist fish, loads of pickles, plenty of tartar sauce, all sandwiched betweeen a soft bun. Who else is ready for lunch??

Ingredients for the fish:

Flounder – Any firm white fish will work well here.

Buttermilk – No buttermilk? Make your own by stirring together 1/2 cup of milk and a tablespoon of vinegar. Let sit for 5 minutes to thicken up.

Panko Breadcrumbs – Panko is a Japanese breadcrumb that is light, airy, and so crispy!

Old Bay Seasoning

Salt

Paprika – We love smoked paprika, but regular will also work just fine.

How to make a homemade tartar sauce:

You should make the tartar sauce before cooking the fish! Store it in the fridge to chill before adding to your sandwich.

Start by mincing your capers. You will need two teaspoons when all is said and done.

Then add the capers to a small bowl with mayo (not miracle whip, please), sweet relish, Dijon mustard, lemon juice, salt and pepper.

Stir to combine and store covered in the fridge until ready to serve.

How to make the fish:

Cut your fish fillets into roughly four ounce pieces.

Get a couple shallow dishes and pour buttermilk into one. Add panko, old bay seasoning, salt, and paprika to the other.

Dip each fillet into the buttermilk, then the panko mix. Flip the fillet and be sure to coat all sides.

Brush your air fryer basket with oil or spritz some oil on the basket with a pump spray bottle.

Place your fillets in the air fryer basket spread out so that they don’t touch. Spritz the fillets with oil and cook for 5 minutes.

Flip the fillets and cook for an additional 3-5 minutes until the fillets are crispy and golden in color.

Add to the bun, and top with your favorite toppings.

Substitutions:

We’re partial to a soft, buttery brioche bun, but any type of bun you like will work great!

Swap out the flounder for cod, halibut, or haddock, if you like. My husband loves to fish, so we’ve used fresh caught bass as well!

Notes

You can use store bought tartar sauce or any other condiments you want. We just love our homemade sauce.

The fish can be substituted for any white fish.

We like to top our sandwiches with loads of pickles, but lettuce and tomato are also delicious.
