Start by dicing the celery and red onion into small, even pieces. Chop the imitation crab into bite-sized chunks so the texture stays nice and balanced. The smaller the cuts, the better each bite will taste.
In a mixing bowl, whisk the mayonnaise with Old Bay seasoning and fresh lemon juice. This creamy dressing will coat the salad perfectly. Add salt and pepper little by little so you can adjust the seasoning to your taste.
Add the chopped crab, celery, onion, and dill into the dressing. Stir everything gently, making sure the crab stays in chunks. This way, the salad holds both flavor and texture.
Sprinkle some extra dill on top for garnish. You can serve it right away, but I personally like chilling it for 30 minutes. It helps all the flavors blend together beautifully.
