Make the crab cake mixture: In a large bowl, whisk together the mayonnaise, egg, Dijon mustard, Old Bay seasoning, lemon zest, Worcestershire sauce, and salt until smooth.
Add the crab: Gently fold in the crab meat, crushed saltine crackers, and parsley. Try not to overmix, as this can break apart the crab.
Chill: Cover the bowl and refrigerate the mixture for at least 30 minutes. This helps the crab cakes firm up and makes them easier to shape.
Shape the crab cakes: Form the mixture into 7-8 patties, about 1/2-inch thick. Lightly coat each crab cake in breadcrumbs, if using.
Preheat the oven: Preheat the oven to 375°F. Lightly spray a baking sheet with nonstick cooking spray and set it aside.
Pan-fry: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Working in batches, cook 2-3 crab cakes at a time for 4-5 minutes per side, or until golden brown. Add the remaining oil as needed between batches.
Bake: Transfer the browned crab cakes to the prepared baking sheet. Bake for 10 minutes, or until heated through.
Make the sauce: While the crab cakes bake, whisk together the mayonnaise, lemon juice, honey, Dijon mustard, garlic, and salt in a small bowl. Taste and add more lemon juice, if needed.
Serve: Serve the crab cakes warm with lemon wedges, fresh parsley, and the honey Dijon sauce.
