Step 1

Preheat. Preheat your grill to 350 degrees F for two-zone grilling.

Step 2

Season. Season the tri tip on all sides with Beef Rub and place it on the indirect heat on your grill.

Step 3

Warm the sauce. Place the butter and BBQ sauce in a medium saucepan and onto your grill to heat through.

Step 4

Grill the tri tip. Grill the tri tip on indirect heat, flipping every 6-7 minutes. Close the lid in between each flip.

Step 5

Add sauce. Mop liberally with BBQ butter sauce after each time you flip the roast. Continue to grill the tri tip until the internal temperature reads one of the following: 115 degrees F for a rare roast (about 30 minutes), 125 degrees F for a medium-rare roast (about 35 minutes), or 135 degrees F for a medium roast (about 40 minutes).

Step 6

Finish grilling. When the roast reaches the desired internal temperature for the doneness you prefer, move it over to direct heat and grill for 2-3 minutes per side or until internal temperature reaches your desired finished doneness: 125 degrees F for rare, 135 degrees F for medium-rare, or 145 degrees F for medium.

Step 7

Rest, slice, and serve. Transfer the roast to a cutting board and let the roast rest for 10-15 minutes. Slice against the grain and serve with additional BBQ sauce.
