Instructions

Step 1: In a shallow dish, combine 3/4 cup all-purpose flour, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Dredge 4 cleaned soft-shell crabs in the flour mixture, shaking off excess.

Step 3: In a small bowl, mix 1/3 cup mayonnaise with 1 teaspoon lemon zest, 1 tablespoon fresh lemon juice, and 1 minced garlic clove until smooth and fragrant.
Step 4: Spread lemon aioli evenly on the cut sides of 4 toasted brioche buns.
Step 5: On the bottom bun, layer 1/4 cup baby arugula and 1 slice of tomato, then place one crispy soft-shell crab on top.
Step 6: Cover with the top bun and serve immediately while warm.
