Instructions
Marinating The Beef:
In a bowl, combine soy sauce, olive oil, minced garlic, black pepper, paprika, thyme, and rosemary to create the marinade.
Place the beef tenderloin tail medallions in a shallow dish and pour the marinade over them. Ensure each piece is evenly coated.
To allow the flavors to mingle, cover the dish with plastic wrap and place it in the refrigerator for at least half an hour.
Cooking The Beef:
After marinating, remove the beef from the refrigerator and let it sit at room temperature for about 10 minutes.
Season the beef with salt to taste.
Heat olive oil and butter in a skillet over medium-high heat.
Add the beef medallions to the skillet and cook for 3-4 minutes on each side for medium-rare doneness, adjusting the cooking time according to your preference. Remove the beef from the skillet and set it aside to rest.
Making The Sauce:
In the same skillet, pour in the beef broth, red wine, Worcestershire sauce, and Dijon mustard. Mix well, making sure to scrape away any browned bits from the pan’s bottom.
Allow the sauce to simmer and reduce by half, about 5-7 minutes.
If preferred, make a slurry out of cornstarch and a tablespoon of water and stir it into the sauce to thicken. Cook for an additional 1-2 minutes until the sauce coats the back of a spoon.
