Preheat the oven to 350 degrees.
In a medium bowl, combine the crab meat and minced onion together.
In a separate bowl, combine the mayonnaise, lemon juice, worcestershire and seasoning.
Using your hands or a spoon, combine the wet mixture into the crab and onion mixture.
Add and combine the panko bread crumbs into the mixture and form into 6, 5 oz. crab cakes.
Bring a large saute pan to medium high heat.
Add 2 T. of olive oil to the pan and allow the oil to heat up.
Add 3 crab cakes to the pan and sear on each side for 2-3 minutes (sear enough to get a golden brown crust). Place half of your crab cakes onto a sheet pan.
Sear and assemble the remaining crab cakes in the rest of the olive oil.
Bake for 7-9 minutes or until done.
