Prepare the garlic butter; in a small bowl, combine butter, minced garlic, fresh rosemary and fresh thyme. Mash with a fork until well combined. Set the butter aside.
Prepare the beef; preheat your oven to 425℉.
Pat dry beef with paper towels.
Season the beef with salt and pepper, then rub with the prepared garlic butter. The ideal way to do it is with clean hands.
Place the beef in a roasting pan. Roast the beef, on the middle rack, for 15 minutes. Then, reduce heat to 325℉ and roast the beef until the inner temperature reaches between 135 and 140℉ degrees. It usually takes about 20 minutes per pound of beef for medium-rare.
Remove the beef from the oven and cover loosely with aluminum foil. Allow the beef to rest for 10 minutes before slicing.
Notes
When you season your beef with salt and pepper, smear it with garlic butter immediately. If you leave your beef seasoned on the counter for a longer time, the salt will remove all its moisture. This is a general rule to follow with any meat cut.
For this recipe use unsalted butter. The salted butter will deliver too much salt to your beef.
