In a large mixing bowl stir together 1/2 cup panko bread crumbs, parsley, green onions, garlic, mayonnaise, lemon zest, dijon mustard, old bay seasoning, egg yolk, 1/4 tsp salt (or to taste) and 1/4 tsp pepper.

Add salmon then toss well to evenly coat with mixture. Scoop mixture 1/3 cup at a time creating 4 equal portions.

Pour remaining 1/2 cup panko into a shallow dish. Press and shape portions into 3-inch patties.

Pour the oil into a large non-stick skillet. Add four salmon patties (if needed carefully tilt pan for oil to run under salmon if it isn't already). Let fry until golden brown on bottom, about 2 minutes. Carefully flip and continue to cook until second side is golden brown and patties are just cooked through, about 2 minutes longer.

Let drain on paper towel. Serve warm with lemon wedges for spritzing over and tarter sauce if you’d like.
