Preheat your oven to 425 degrees F (220 degrees C).
Season the beef tenderloin with salt and generously coat with the crushed black peppercorns, pressing them into the meat to adhere.
Heat olive oil in a large ovenproof skillet over high heat. Sear the tenderloin on all sides until well browned, about 2-3 minutes per side.
Transfer the skillet to the preheated oven and roast the tenderloin to the desired level of doneness, about 20-25 minutes for medium-rare. Use a meat thermometer to check for an internal temperature of 135 degrees F (57 degrees C).
While the beef is roasting, start preparing the Béarnaise sauce. In a small saucepan, combine the egg yolks and tarragon vinegar over low heat, whisking constantly until the mixture thickens and doubles in volume.
Remove the saucepan from heat and slowly drizzle in the melted butter, continuing to whisk until the sauce is thickened and smooth.
Stir in the chopped tarragon and minced shallot, then season with salt to taste. Keep the sauce warm until ready to serve.
Once the beef tenderloin is cooked, remove it from the oven and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute throughout the meat.
Slice the beef tenderloin into thick medallions and serve with the warm Béarnaise sauce drizzled over the top or on the side for dipping.
