What kind of fish should I use for a copycat Filet-O-Fish sandwich?

Cod is the most authentic for a McDonald’s fish filet, but any mild white fish works.

Can I use store-bought tartar sauce?

Yes, but the homemade version really makes this filet sandwich stand out.

Does McDonald’s use a full slice of cheese?

No - McDonald’s uses half a slice, but you can use a whole slice of cheese if you like more melty cheese.

Can I make this ahead?

You can prep everything ahead, but fry just before serving for the crispiest fish filet sandwich.

Instructions

In a bowl whisk together your egg, mayo, mustard, cornstarch and flour and ½ teaspoon of the kosher salt.
In a food processor pulse your panko breadcrumbs a bit just to get them a little finer.
Combine the breadcrumbs with the paprika and remaining salt.
Heat about an inch of oil in a large skillet over medium high heat.
Dredge the filets in the wet mixture then in the dry and set aside.
Once all the filets are breaded add them to the oil, careful not to overcrowd.
Fry them about 3-4 minutes per side until crispy golden brown on each side.
Meanwhile make your tartar sauce.
Combine the mayo, relish, sugar and onion.
Set on a wire rack or paper towel lined plate to drain any excess grease.
To assemble your sandwiches place a slice of cheese on the bottom of each bun and top with a hot filet.
Spoon your homemade tartar sauce on top of each sandwich and top with the top bun.
Serve!
