Grouper Sandwich Recipe

Preparation Steps

1. 1

   Prepare the Tartar Sauce

   In a bowl, mix together mayonnaise, dill pickles, capers, lemon juice, hot sauce, and salt. Set aside.

2. 2

   Marinate the Onions

   Soak the thinly sliced onions in buttermilk for at least 30 minutes.

3. 3

   Prepare the Onion Straws

   In a separate bowl, mix flour, cornstarch, salt, and black pepper. Drain the onions from the buttermilk and toss them in the flour mixture until well-coated.

4. 4

   Fry the Onion Straws

   In a deep pan, heat vegetable oil over medium heat. Fry the coated onion straws in batches until golden brown and crispy. Drain on paper towels.

5. 5

   Cook the Grouper

   Season the grouper fillets with salt and black pepper. Heat olive oil in a grill pan over medium-high heat. Cook the grouper for about 4-5 minutes on each side, or until cooked through and flaky.

6. 6

   Assemble the Sandwich

   Toast the brioche buns lightly. Place lettuce on the bottom bun, then add the cooked grouper. Top with the tartar sauce and a generous amount of onion straws. Close the sandwich with the top bun.
