Whisk together mayo, egg, red onion, garlic, dijon mustard, Worcestershire sauce, old bay seasoning, hot sauce, and parsley.
Check the crab meat to make sure there aren’t any lingering shells. Add the crab meat and breadcrumbs to the mayo mixture and fold together.
Use a ⅓ measuring cup to scoop out mixture and form crab cakes. Place on a baking sheet and cover with plastic wrap. Refrigerate for 40 minutes.
Allow a pan to warm over medium heat. Melt butter and olive oil together. Place 1-2 patties in the pan at a time.
Cook for 3-4 minutes on each side, until golden brown.
To make the tartar sauce, simply whisk together all of the ingredients.
Notes
Finely dice garlic and onion as much as possible.
Use quality lump crab meat, such as crab meat from blu crabs or dungeness crabs. If you can only find jumbo lump crab meat, break the meat into small pieces.
Chilling the crab cakes prior to cooking prevents them from falling apart. If you’d like to cook them immediately, you can - just be very gentle with the patties.
