Frozen minced fish patties have got nothing on the golden and crispy fillets you’ll cook up with this quick and easy recipe!

As a kid, I loved fish sticks. There were also these rectangular fish filets from a box in the freezer, just big enough to fit on a bun. My mom would heat them up and slather the whole thing in store-bought tartar sauce. Oh, and don’t forget the frozen crinkle fries. That was dinner some nights—a feast worthy of any school cafeteria. And you know what? I thought it was delicious.
Fast-forward to today, and I still have a soft spot for fish sandwiches. However, I’ve graduated from those boxes of frozen patties to a more grown-up version.
This fish sandwich recipe delivers the classic flavors I remember with an elevated twist: panko crust. Your standard breadcrumbs just can’t match the crunch panko provides, a perfect contrast to the flaky white fish. Plus, the paprika, garlic, and onion powder bring savory depth to the mild flavor of the white fish. And don’t get me started on the homemade tartar sauce! It takes mere minutes to prepare, but it tastes way fresher than the store-bought stuff. And you can control the balance of ingredients to your personal tastes.
Whether it’s for a weeknight dinner or a special occasion, this fish sandwich brings flavor and nostalgia to the table.

Panko—breadcrumbs perfected
Whether deep-fried, blackened, or grilled, there’s no shortage of ways to make a proper fish sandwich. Regular breadcrumbs are one option for coating your fillets— but panko breadcrumbs reign supreme. In this recipe, they make all the difference. Here’s what makes panko breadcrumbs a home cook’s best friend.
These staples of Japanese cuisine are bigger and lighter than traditional breadcrumbs, giving fried or baked foods a crispier, crunchier coating. They’re made from crustless white bread and create an airy texture and a deliciously golden appearance that adds true plate appeal. Not only that, but panko crumbs soak up less oil than regular breadcrumbs, helping your fish fillets stay crunchy on the outside while the fish inside remains moist and flaky. For that perfect bite and extra crunch, panko is hard to beat.

How do I store leftovers?
Storing a fully assembled fish sandwich is not a great idea, as the bun will quickly become soggy, the lettuce will wilt, and the fish fillet will lose its crispiness. But you can refrigerate your fillets separately in an airtight container for up to 4 days, and the tartar sauce will keep in a mason jar or other airtight container in the fridge for up to 7 days. Reheat the fish in your oven or air fryer at 350°F for about 5–7 minutes, or pan-fry it over medium-low heat for roughly the same time. Then enjoy the fish on its own or assemble a sandwich with a fresh bun and toppings.

Serving suggestions
Stick with the classics, folks. Serve the fish sandwich with a side of Homemade French Fries or Baked Onion Rings. Also, no fish sandwich is complete without a Coleslaw. For a lighter take, Vinegar Coleslaw offers a tangy twist. Speaking of light, these Air-Fryer Carrot Fries are a nutritious alternative to standard fries—serve them with some Garlic Parmesan Sauce!


Ingredients
For The Fish Sandwiches:
- 4 white fish fillets about 6 ounces each
- Salt to taste
- Black pepper to taste
- 1/2 teaspoon paprika
- 3/4 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 cup all-purpose flour
- 2 eggs beaten
- 1 cup panko breadcrumbs
- Neutral oil for frying, vegetable or canola

For The Tartar Sauce:

Instructions
Make The Fish Fillets:
- Pat the fish fillets dry and season them evenly with salt, pepper, paprika, garlic powder, and onion powder. Set up a breading station of three bowls: one with flour, another with beaten eggs, and a third with panko breadcrumbs.

- Dredge each fillet in the flour, dip it into the egg, then coat it completely with panko breadcrumbs. Set aside on a plate.

- Heat a thin layer of oil in a large skillet over medium-high heat (about 350°F). Fry the breaded fish until golden and cooked through, about 3-4 minutes per side. Lightly toast the buns.

Make The Tartar Sauce:
- In a separate bowl, combine the light mayonnaise, sweet pickle relish, lemon juice, salt, and pepper. Stir well and set aside.

Assemble The Sandwiches:
- Spread a generous layer of tartar sauce on the bottom bun, add a lettuce leaf if desired, and place a fried fish fillet on top. Cap with the top bun and serve immediately.
