This is my mom's recipe that she's been making for special occasions for as long as I can remember. These directions will produce meat that is medium-rare in the very center of the tenderloin. If you want your meat more well done, add on 10 minutes and check it by cutting a small nick in the center of the meat - keep repeating until the meat is done to your liking.
02Combine the salt, pepper, garlic powder, onion powder, Worcestershire sauce & mustard.
03Spread this spice paste over the tenderloin, coating the whole exterior.
04Place on a broiler pan and drizzle half of the melted butter over the tenderloin. Broil for 5 minutes. Turn tenderloin over to other side & drizzle with the remaining butter. Broil for another 5 minutes.
05NOTE - BEGIN MAKING SAUCE NOW, SEE INSTRUCTIONS BELOW.
06Set the oven to 350 degrees and bake the tenderloin at this temperature for 45 minutes.
07Remove from the oven and let sit for 10 minutes before slicing. Serve with Gorgonzola Sauce.
08GORGONZOLA SAUCE:.
09Bring the cream to a full boil in a medium saucepan over medium-high heat, then continue to simmer rapidly for 35 to 40 minutes, until it's thickened like a white sauce, stirring occasionally.
10Remove the pan from the heat & add the gorgonzola, parmesan, horseradish, salt, and pepper. Whisk rapidly until the cheeses melt, add parsley, and serve.
