- 2 tablespoons sweet pickle relish

How to Make a Filet Fish Style Sandwich
Step 1: Make the Tartar Sauce
Add mayonnaise, sweet pickle relish, lemon juice, and Dijon mustard to a small bowl. Stir until the mixture is smooth and evenly combined.
Taste the sauce and add a small amount of salt and black pepper as needed. Cover and refrigerate it while you prepare the fish. Chilling the sauce gives the flavors time to blend.
Step 2: Prepare the Fish
Pat each fish fillet dry with paper towels. Removing excess moisture helps the breading stick better and prevents the coating from becoming soggy.
Set up three shallow bowls. Place flour in the first bowl, beaten eggs in the second, and panko breadcrumbs in the third.
Mix the panko with garlic powder, onion powder, paprika, salt, and black pepper. This seasoned coating gives the fish a savory flavor and crisp texture.
Step 3: Bread the Fillets
Coat one fish fillet in flour and shake off the excess. Dip it into the beaten egg, making sure the surface is covered.
Transfer the fillet to the seasoned panko mixture. Press the breadcrumbs gently onto the fish so the coating sticks evenly.
Repeat the process with the remaining fillets. For a cleaner coating, keep one hand for the dry ingredients and the other for the egg.
Step 4: Cook the Fish
Choose one of the following methods based on the texture and convenience you want.
Pan-Frying: Heat about 1 inch of vegetable oil in a skillet over medium heat. Carefully add the breaded fillets and cook for about 3–4 minutes per side, or until golden brown and cooked through. Transfer them to a paper towel-lined plate.
Oven-Baking: Heat the oven to 425°F (220°C). Place the breaded fish on a parchment-lined baking sheet and lightly spray the coating with cooking oil. Bake for 12–15 minutes, turning halfway through cooking.
Air-Frying: Preheat the air fryer to 400°F (200°C). Lightly spray the breaded fillets with cooking oil and cook for about 10–12 minutes, turning them after 6 minutes. Cook until the coating is crisp and the fish is fully cooked.
Fish is ready when it flakes easily with a fork and reaches a safe internal temperature of 145°F (63°C).
Step 5: Warm the Buns
Warm the hamburger buns just before assembling the sandwiches. For soft, steamed-style buns, wrap them in a damp paper towel and microwave for about 15–20 seconds.
You can also place the buns in a steamer basket for 1–2 minutes. If you prefer a little crunch, lightly toast the cut sides instead.
Step 6: Assemble the Sandwiches
Place one slice of American cheese on each bottom bun. Add a hot fish fillet directly over the cheese so the heat softens and melts it slightly.
Spoon tartar sauce over the fish. Add lettuce or shredded cabbage if you want extra freshness and crunch.
Finish with the top bun and serve immediately. The sandwich tastes best while the fish is hot and the coating is crisp.
Tips for the Best Fish Sandwich
Use fish fillets that are similar in thickness so they cook at roughly the same rate. Patting the fish dry before breading is especially important because excess moisture can weaken the crispy coating.
Do not overcrowd the skillet or air fryer. Too many fillets at once can reduce airflow or oil temperature and leave the breading less crisp.
For extra crunch, press the panko firmly onto each fillet before cooking. If you are baking or air-frying, a light coating of cooking spray helps the breadcrumbs brown evenly.
Prepare the tartar sauce ahead of time for an easier meal. Homemade sauce can be refrigerated for up to 3 days when stored properly.
What Fish Is Best for This Sandwich?
Cod, haddock, and pollock are excellent choices because they have a mild taste and flaky texture. Cod gives you a thicker, tender fillet, while pollock is a budget-friendly option with a slightly lighter texture.
Fresh or frozen fish can both work. If using frozen fillets, thaw them completely in the refrigerator and pat them dry before breading.
How to Store and Reheat Leftovers
For the best quality, store cooked fish separately from the buns and tartar sauce. Refrigerate leftovers in an airtight container and use them within 2–3 days.
To restore some of the crisp texture, reheat the fish in an air fryer or oven rather than the microwave. Avoid assembling the sandwich until the fish is hot.
Nutrition Information
The fried version provides approximately 550–600 calories per sandwich, depending on the size of the fish fillet, amount of oil absorbed, bun, cheese, and sauce.
Each sandwich contains about 28 grams of protein, 45 grams of carbohydrates, and 30 grams of fat. Baking or air-frying can reduce the amount of added cooking fat compared with deep or pan frying.
For a lighter sandwich, use a smaller amount of tartar sauce, choose a lean fish fillet, and air-fry the breaded fish.
Frequently Asked Questions
Can I use frozen fish for this recipe?
Yes. Thaw frozen fish completely in the refrigerator, then pat it very dry before adding the flour and breadcrumb coating.
What is the best fish for a filet-style sandwich?
Cod, haddock, and pollock are great choices because they have a mild flavor, flaky texture, and firm enough flesh for breading.
Can I bake the breaded fish instead of frying it?
Yes. Bake the fillets at 425°F (220°C) for 12–15 minutes, turning halfway through and lightly spraying the coating with oil.
Can I make this fish sandwich in an air fryer?
Yes. Air-fry the breaded fillets at 400°F (200°C) for about 10–12 minutes, turning them halfway through cooking.
How do I make soft steamed-style hamburger buns?
Wrap each bun in a damp paper towel and microwave it for about 15–20 seconds, or steam the buns for 1–2 minutes.
Can I prepare the fish ahead of time?
Yes. Bread the uncooked fillets and refrigerate them for up to 12 hours before cooking, while keeping the tartar sauce refrigerated separately.
Can I make this recipe gluten-free?
Yes. Replace the regular flour and panko with certified gluten-free alternatives and use gluten-free hamburger buns and condiments.
How do I keep the fish coating crispy?
Pat the fish dry, coat it evenly, avoid overcrowding during cooking, and serve it immediately after cooking for the best crunch.
