Ingredients

Instructions

  1. 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.
  2. Step 2: Heat 1/4 cup canola oil in a large skillet over medium-high heat until shimmering. Add the crabs and cook for 3-4 minutes per side until golden brown and crispy. Transfer to paper towels to drain.
  3. 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.
  4. Step 4: Spread lemon aioli evenly on the cut sides of 4 toasted brioche buns.
  5. 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.
  6. Step 6: Cover with the top bun and serve immediately while warm.

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
