    30 minutes

  • Yield

    Makes 4

Ingredients

1 small red onion, thinly sliced into rounds
4 oz. bread-and-butter pickles, plus ½ cup brine
¾ cup mayonnaise
⅓ cup chopped dill
2 tsp. hot sauce
1 tsp. freshly ground black pepper
2 tsp. fresh lemon juice, plus wedges for serving
1 Tbsp. kosher salt, divided
2 large eggs, lightly beaten
1½ cups panko (Japanese breadcrumbs)
½ cup all-purpose flour
2 flounder fillets (about ⅔ lb. total), cut in half crosswise on a diagonal
⅔ cup vegetable oil
3 cups shredded iceberg lettuce
8 slices Pullman bread
1 cup potato chips, plus more for serving

Preparation

  1. Step 1

    Combine onion, pickles, and pickle brine in a small bowl.

    Step 2

    Mix mayonnaise, dill, hot sauce, pepper, 2 tsp. lemon juice, and ½ tsp. salt in another small bowl.

    Step 3

    Place eggs, panko, and flour in 3 separate shallow medium bowls. Season each fish fillet with ½ 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.

    Step 4

    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 ½ tsp. salt total.

    Step 5

    Spread 1 heaping Tbsp. mayonnaise mixture on one side of each slice of bread. Pile each bottom slice with ¾ cup lettuce, 1 fish fillet, a small handful of potato chips, and ¼ 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.

    Step 6

    Do Ahead: Pickled onions and dill sauce can be made 1 day ahead. Cover and chill.
