Gather the ingredients.
Drain the crabmeat and pick through it, discarding any shells and cartilage. Put the crabmeat in a bowl and set it aside.
Crush the saltine crackers until very fine and mix with the egg, mayonnaise, Dijon mustard, Old Bay, Worcestershire sauce, and salt.
Fold in the crab gently. Only mix enough to combine ingredients (take care not to break up the crab into fine shreds).
Shape into 6 crab cakes, cover, and refrigerate for at least 1 hour.
Heat the vegetable oil in a large nonstick skillet over medium-high heat. Cook the crab cakes until golden brown, 3 to 5 minutes per side. Transfer to a plate.
Serve the crab cakes with tartar sauce, rémoulade , or simply with a squeeze of lemon.
