Line a baking sheet with parchment or spray with nonstick cooking spray. Heat oven to 350°F.
In a large sauté pan, over medium heat, add 2 tablespoons olive oil. Add red pepper and onion/shallot and cook until softened. Add garlic and cook for about 1 more minute. Set aside to cool.
In large bowl, combine bell pepper onion mixture, egg, Worcestershire sauce, parsley, mustard, seasonings, and mayonnaise. Blend well and add crab and ½ cup panko. Blend gently, but do not over mix as you want crab meat to retain small chunks.
Test to see if the crab cakes will hold together in a small patty. If too dry, add a small amount of extra mayonnaise. If too loose, add a bit more panko.
In a shallow bowl add remaining ½ cup of panko or breadcrumbs.
Wipe sauté pan clean and add remaining 2 Tablespoons of olive oil to coat pan. Heat to medium.
Scoop about 2 tablespoons of mixture for mini’s and about ¼ cup for large crab cakes and form it into a thick patty. Roll lightly in remaining panko to coat.
Sauté on medium heat until lightly browned, about 3-5 minutes per side.
Transfer crab cakes to the prepared baking sheet. Bake crab cakes in the oven for about 12-15 minutes. They should be lightly browned and firm on the outside.
Let cool slightly, remove to a serving platter and serve with cocktail sauce.
