Rub the marinade on the roast, making sure the entire roast is covered.
Let the Tri-Tip Roast marinade in the fridge for at least 12 hours, no more than 24 hours. I put my roast in a zip top bag, and it works great. You can also leave it in a glass or ceramic dish, covered.
Smoking the Tri-Tip Roast
Heat smoker accordingly. I set mine on the "Smoke" setting and let it heat for 5-10 minutes with the lid open.
Raise temperature on smoker to 225 degrees. Remove roast from zip top bag or dish. If using a probe thermometer, or other type of thermometer that stays in the meat when it cooks, insert it into the thickest part of the meat. (If it is not an electronic digital read, make sure you can see the face of the thermometer when you place it on the grill). Place roast on the smoker. I place it right on the grill, no pan underneath.
Shut the lid of the smoker (make sure you have enough pellets in the smoker), and let it smoke for 1 1/2 - 2 hours. Check the meat temperature at 90 minutes. You want it to read anywhere from 130-145 degrees, depending on what you like. 130 degrees, after resting will be rare, and 145 will be medium-rare (perfect to me!). If you do not have a meat probe that will give you a digital read, do not open the lid and check the meat, until is has cooked for 90 minutes (one hour and a half). Then start checking the meat and let it smoke until it reaches your desired temperature.
Once the roast has reached your desired temeprature, pull the meat off the grill and cover with foil and let it rest 20 minutes.
When you are ready to slice/cut it, take note of the fibers. The fibers will run in two different directions. You need to cut each section against the grain. The easiest way to do this, is cut the roast in two where the fibers change dierction. This will make it easier to cut each piece against the grain.
I eat mine on a toasted hoagie bun with mayo, BBQ sauce, and yellow onion. But you can slice it up and eat with a baked potato, roasted veggies, rice or a side salad.
