Simple to make, this tri-tip marinade adds incredible flavor to any tri-tip roast. Most of the time, I make my tri-tip with the simple olive oil, garlic, and rosemary marinade listed; however, I do have an extra barbecue version to share with you as well that is great in the summer months.
For the Rosemary Garlic Marinade, mix all the ingredients. Pour the marinade over the tri-tip roast and turn to coat evenly. Cover and refrigerate up to 24 hours. If you don't use the vinegar, you can marinate for up to 2 days.
For the BBQ Marinade, mix the olive oil with the spices and pour the mixture over the tri-tip, turn to coat evenly, and refrigerate up to 24 hours. Brush with the BBQ sauce in the final minutes of cooking.
Once your tri-tip has marinated, choose your favorite method of cooking. For oven-roasted tri-tip, heat the oven to 425ºF and allow 10-15 minutes per pound for cooking + 20 minutes for resting.
To smoke your tri-tip, heat the smoker to 225ºF and smoke the tri-tip about 2 hours or until your desired temperature is reached. Rest 20+ minutes and slice against the grain.

Notes
The nutrition facts were calculated for the Rosemary Garlic Marinade.Beef Temperature Guide:
Rare – 125ºF most of the meat will be red with a little pink around the edges.
Medium rare – 135ºF looks like the beef tenderloin pictured here with a good amount of red in the center, turning to pink, then brown near the edges.
Medium – 145ºF has just a bit of red in the center but is mostly light pink with brown edges.
Medium well – 150ºF barely a hint of pink in the center and mostly brown throughout.
Tri-tip is at its best tender and juicy at medium-rare, but medium has pretty good results too. I personally don't recommend medium-well.
