  • Wrap in plastic wrap and place in the refrigerator until ready to put on the grill or smoker.

Setup and Start the Grill or Smoker

  • Start or light your smoker and bring the temperature up to 225°F. If using a gas or charcoal grill, only light one side and set the grill up for indirect heat.

  • If not using a pellet grill, add wood to the smoker using either chunks or a smoker box or pellet tube smoker placed over the hot charcoal or burners on a gas grill.

Smoke the Sirloin Tip Beef Roast

  • Place the sirloin tip beef roast in the cooking chamber away from any direct heat. Place a temperature probe into the deepest center part of the roast.

  • Smoke for about 2 hours or until the internal temperature reaches about 120°F. This may take longer on cold days or larger roasts.

Prepare the Rosemary Cream Sauce

  • While the sirloin tip roast is smoking, you can prepare the rosemary cream sauce.
  • Place a saucepan over medium heat and melt the butter into the olive oil.
    1 tablespoon Salted Butter, 1 teaspoon Olive Oil
  • Add the shallot and stir and cook for about 3-4 minutes until soft. Stir in the wine for about 1 minute and then the beef stock and the sprig of rosemary.
    1 Shallot, ¼ cup Beef Stock or Broth, ¼ cup Dry White Wine, 1 sprig Fresh Rosemary
  • Simmer for about 10 minutes until or until the liquid has reduced by a quarter to half. Remove from heat or turn to very low and set aside until serving time.

Reverse Sear the Smoked Sirloin Tip Roast

  • Prepare to move the smoked sirloin tip to the hot side of the grill for reverse searing, or, prepare a hot skillet with cooking oil or Grill Grate on a pellet grill to sear the roast when it is ready.
  • Once the internal temperature of the smoked sirloin tip reaches 120°F, move the beef roast to the selected place for reverse searing. Rotate about 2 minutes on each side until it is fully seared on all edges and the internal temperature has reached 125-130°F.

Rest the Smoked Sirloin Tip Roast and Finish Rosemary Cream Sauce

  • Let the smoked sirloin tip rest on a cutting board, uncovered, for about 20-30 minutes.
  • Place the rosemary cream sauce "broth" back on medium heat and stir in the whipping cream. Heat and stir until hot and the desired consistency. Remove the rosemary sprig before serving. Add additional salt and pepper to taste.
    ¼ cup Heavy Whipping Cream, Salt and pepper to taste
  • Using a good meat slicing knife, slice the smoked sirloin tip roast in about ¼" thick slices. Only slice what you plan to eat so the meat does not dry out.
