Season the beef with the salt and freshly ground pepper. Set aside at room temperture while preparing other ingredients.
Preheat the oven to 350°F degrees and line a baking dish with aluminum foil, unless you are using a cast iron or oven safe skillet, then this is unnecessary.
In a medium bowl, whisk together the mayonnaise, bread crumbs, egg white, parsley, lemon juice, Worcestershire sauce and Old Bay seasoning. Gently fold in the crab meat. Place in the refrigerator until ready to use.
If using a well-seasoned cast iron pan, no additional oil is needed, but if using stainless steel or another type of pan, heat the oil over medium-high heat. When hot, carefully add the beef. Depending on preference, sear for 2-4 minutes on each side. Remember, the steak will continue cooking in the oven, so you want it to be undercooked, just nicely seared on the outside. If you like your steak well done, cook for longer.
Remove the steaks and place onto prepared baking dish. Top each generously with crab imperial mixture. Place in the hot oven for 12 minutes, or until crab imperial turns golden brown on top.
Remove and spoon clarified butter or beurre blanc sauce over each filet mignon. Top with parsley and serve with lemon wedges, if desired.

Notes
You can prepare the crab topping ahead of time, but it is really best enjoyed fresh from the oven.Store leftovers in an airtight container in the refrigerator for up to 4 days. It can probably go longer, but I’m always careful with seafood. Reheat in the oven or microwave.
