The Ultimate Fish Fillet Sandwich Recipes

Steps:

• For the tartar sauce: Mix together the mayonnaise, relish, capers, dill, lemon juice, salt, pepper, sugar and onion in a bowl and refrigerate.
• For the fish: Sprinkle the lemon juice over the fish fillets. Combine the milk, eggs, salt and pepper in a shallow bowl. Put the flour on a large plate. Combine the panko and seafood seasoning on another.
• Heat 2 inches oil to 350 degrees F in a large Dutch oven.
• One at a time, dip the fish into the flour, then the egg and milk mixture, then the panko. Set on another plate or small baking sheet. Place the fish in the oil and fry, turning once, for 3 to 4 minutes total (if you are using the shallow-frying method, cook both sides until golden brown, 2 to 3 minutes). Transfer the fish with tongs to a plate lined with paper towels or a wire rack set in a baking sheet. (I like to hit my fish with a little salt and lemon juice while it's hot.)
• Meanwhile, toast the buns, by melting the butter in a pan and cooking them in it or by buttering the buns and broiling them until slightly golden.
• Top the bun bottoms with the cheese and the fish, then spread the bun tops with tartar sauce and top your sandwiches.

Steps:

• Combine onion, pickles, and pickle brine in a small bowl.
• Mix mayonnaise, dill, hot sauce, pepper, 2 tsp. lemon juice, and 1/2 tsp. salt in another small bowl.
• Place eggs, panko, and flour in 3 separate shallow medium bowls. Season each fish fillet with 1/2 tsp. salt. Working one at a time, dredge fish in flour, shaking off excess. Coat evenly with egg, allowing excess to drip back into bowl. Coat with panko, pressing to adhere. Transfer fish to a plate.
• Heat oil in a large skillet over medium. Cook fish until breading is golden brown and cooked through, 2-3 minutes per side. Transfer fish to a paper towel-lined plate. Season fillets with 1/2 tsp. salt total.
• Spread 1 heaping Tbsp. mayonnaise mixture on one side of each slice of bread. Pile each bottom slice with 3/4 cup lettuce, 1 fish fillet, a small handful of potato chips, and 1/4 cup onion mixture. Close sandwich with second slice of bread, mayo side down, and push down lightly to crush potato chips. Transfer to a platter. Repeat with remaining sandwiches. Serve with lemon wedges and more potato chips alongside.
• Do Ahead: Pickled onions and dill sauce can be made 1 day ahead. Cover and chill.

Steps:

• Mix 2 tsp of each Old Bay seasonings, 1 tsp salt, and 1 tsp pepper in a small bowl.
• Set aside.
• Season both sides of fish fillets with the remaining seasonings left in the bowl.
• Mix mayo and remaining seasonings and the lemon juice.
• Set aside.
• Grill fish on a George Foreman grill, panini maker or griddle til done. About 4 minutes in a Foreman grill.
• Put sandwiches together by layering the fish, cheese, tomato and mayo mixture when the fish is cooked.

Steps:

• Prepare the tartar sauce: In a medium bowl, whisk together mayonnaise, pickles and pickle brine, shallot, dill, capers and soy sauce. Season with salt to taste and set aside. (Makes 3/4 cup.)
• Prepare the fried fish: Heat oil in a large, straight-sided skillet over medium. Place flour, eggs and panko in 3 separate medium shallow bowls. Season flounder on both sides with salt and dredge in flour, dusting off excess, then transfer to egg wash, allow excess to drip off, then coat with panko.
• Working in batches, fry about 4 breaded fillets at a time until golden brown and cooked through, about 1 1/2 minutes per side. Transfer to a wire rack and season with salt. Repeat with remaining fish.
• Assemble the sandwiches: Spread tartar sauce on both sides of each bun. Place 1 piece of fried fish on each bottom bun, then add a slice of cheese on top and another piece of fish on the cheese. The residual heat from the fish will help melt the cheese. Sandwich together and serve immediately.

Steps:

• Preheat grill or broiler. Brush cod with lime juice; sprinkle with lemon pepper. Place on an oiled grill rack over medium heat or in a greased 15x10x1-in. pan. Grill, covered, or broil 4 in. from heat until fish just begins to flake easily with a fork, 4-5 minutes per side., Meanwhile, mix mayonnaise, mustard and honey; spread onto bun bottoms. Top with fish, lettuce, tomato and bun tops.
