3 1/2 - 4
pounds beef tenderloin roast, trimmed
stick unsalted butter, softened but not melted
whole head of garlic
small shallot, minced
tablespoon Worcestershire sauce
teaspoon dijon mustard
1 1/2
tablespoons red wine reduction
tablespoons fresh rosemary, minced
tablespoon canola oil
1 1/2
teaspoons salt
teaspoon fresh ground pepper
cooking twine



Preheat the grill to around 400 degrees. Take an entire head of garlic and cut the top third completely off. Place the garlic on a piece of aluminum foil. Drizzle with extra-virgin olive oil and sprinkle with salt. Wrap tightly in foil and place over indirect heat on the grill for 35 to 40 minutes. Carefully remove and unwrap, and squeeze the softened cloves out of the blub and into a bowl. Mash with a fork and set aside.


Meanwhile, in a small saucepan bring 1/3 cup red wine to a low simmer. Simmer uncovered until thickened and reduced to 2 tablespoons or so.


With paper towels, pat the tenderloin dry. Fold the tapered ends of the tenderloin under itself then secure tightly with cooking twine. Continue to tightly tie the tenderloin in sections so it forms a uniform shape. This will guarantee even cooking.


Cream together the butter, roasted garlic, 1 ½ tablespoons red wine reduction, Worcestershire sauce, shallot, rosemary, Dijon mustard, salt and pepper together until well combined.


Using cold wet hands to keep the butter from sticking to your hands, pat the butter all over the tenderloin. Cover in plastic wrap and chill in the refrigerator for 1 hour or up to a day.


Let tenderloin come to room temperature while you heat the grill to 250 degrees.


Remove the tenderloin from the plastic wrap and carefully wrap it in aluminum foil, making sure the juices and melted butter will not leak out when rotating while on the grill. Remember, you’re basically making a buttery, herbaceous flavor packet for your tenderloin to slow roast inside.


Place the tenderloin in the Char-Broil Roast and Grill Rib Rack on the center of your grill, and slow cook for 2 to 3 hours until the desired internal temperature has been reached. Flip tenderloin every 30 minutes or so, for a flavorful butter-baste. Start checking at 2 hours, as ours was done at 2 hours and 20 minutes.


Remove at 125 for rare or130 for medium rare. Keep in mind we are reverse-searing the tenderloin, so it will continue to cook a bit then. Let sit at room temperature for 10 minutes and increase the heat on the grill to medium-high heat.


Carefully remove the tenderloin from the foil, reserving all of the juices that have collected inside. Sear tenderloin on the grill until the meat is well-browned on all sides.


Transfer tenderloin to a cutting board and allow to rest for 5 minutes. Slice into ½ inch slices and drizzle with reserved cooking juices. Serve.

    Just to preface, I did this all with a sirloin roast instead of tenderloin. It was way to heavy on the rosemary, I would use about half or maybe even a quarter of the listed amount. Rosemary is good flavor, but like anything, too much just overpowers everything else.
