How to Make the Best FISH FILET SANDWICH in Your City
Your City: There's nothing like a fish filet sandwich where the coating actually shatters when you bite it, the fish steams out hot and flaky underneath, and cold tartar sauce is already running toward your wrist by the second bite.
What Most People Don't Know About Making a Fish Filet Sandwich
- Dry-brine the fish before you bread it. Season the raw fillets and let them sit 15 minutes, then pat them bone-dry. The salt pulls surface moisture out and firms the flesh, so you get a tighter, meatier flake instead of a mushy one — and a dry surface is the single biggest factor in whether your coating crisps or steams.
- Chill the breaded fillets before they hit the oil. Twenty minutes in the fridge lets the coating "set" onto the fish. Skip this and the breading slides off in the oil and fries up soft; do it and it welds on and shatters like glass.
- Steam the buns — don't toast them. The pillowy, cloud-soft bun is what separates a great fish sandwich from a dry one. A toasted bun fights the delicate fish for texture; a steamed bun gives way and lets the fish be the crunch.
Ingredients
For the fish:
- 4 skinless cod fillets (haddock or pollock also work), 4–5 oz each, about ¾-inch thick
- 2 tsp Bald Buck Seasoning
- 1 cup all-purpose flour
- ¼ cup cornstarch
- ½ tsp black pepper
- 2 large eggs
- 2 tbsp water
- 2 cups panko breadcrumbs
- Neutral oil, for frying (about 1 quart)
For the tartar sauce:
- ¾ cup mayonnaise
- 2 tbsp dill pickles, finely chopped
- 1 tbsp capers, chopped
- 1 tbsp shallot, finely minced
- 1 tsp fresh lemon juice
- 1 tsp fresh dill, chopped (or ½ tsp dried)
- ½ tsp Bald Buck Seasoning
To assemble:
- 4 soft potato or white burger buns
- 4 slices American cheese
Instructions
- Dry-brine the fish. Pat the fillets dry, season both sides evenly with 2 tsp Bald Buck Seasoning, and set on a rack for 15 minutes. When you see beads of moisture on the surface, blot them off completely with paper towels. Dry fish is crispy fish.
- Make the tartar sauce. Stir together the mayonnaise, pickles, capers, shallot, lemon juice, dill, and ½ tsp Bald Buck Seasoning. Refrigerate while you cook — even 20 minutes lets the flavors marry.
- Set up the breading station. In the first dish, whisk the flour, cornstarch, and black pepper. In the second, beat the eggs with 2 tbsp water. In the third, add the panko.
- Bread the fillets. Dredge each fillet in the flour mixture (shake off excess), then the egg, then press firmly into the panko so it fully coats and sticks. Set the breaded fillets on a rack.
- Chill the coating. Refrigerate the breaded fillets, uncovered, for 20 minutes. This sets the crust so it won't slough off in the oil.
- Heat the oil. Bring 1½ inches of oil to 350°F in a heavy pot or deep skillet. Use a thermometer — too cool and the coating soaks up grease, too hot and the outside burns before the fish cooks.
- Fry the fish. Fry the fillets 3–4 minutes, turning once, until deep golden and the internal temperature hits 145°F. Don't crowd the pot — fry two at a time so the oil holds temperature. Drain on a rack, not paper towels, so the bottoms stay crisp.
- Melt the cheese. Lay a slice of American cheese on each hot fillet the moment it comes out of the oil; the residual heat will half-melt it into the crust.
- Steam the buns. Set the buns cut-side up in a covered steamer or a dry pan with a tight lid over low heat for 30–60 seconds, until soft, warm, and pillowy.
- Assemble. Spread tartar sauce on both cut sides of each bun. Set the cheese-topped fillet on the bottom bun, add a little extra tartar sauce on top if you like it messy, and cap it. Serve immediately.
Make-Ahead Option
The tartar sauce is better made ahead — mix it up to 3 days in advance and keep it refrigerated; the pickle and caper flavor deepens as it sits. You can also bread the fillets and hold them chilled on a rack for up to 4 hours before frying.
