What Exactly Is A Tri-Tip Roast?
A tri-tip is actually part steak and part roast and absolutely beefy delicious. Where is the tri tip roast cut from? It’s a cut taken from the bottom of the sirloin.
The top sirloin produces cuts great for grilling, while the bottom sirloin produces cuts like the tri-tip roast and the sirloin bavette, which are good for roasting or grilling.
Tri tip roasts may be labeled as bottom sirloin roast.
It’s a lean triangular muscle with plenty of beefy flavor. Tri-tip roasts are most famous grilled as the Santa Maria Tri-Tip.
How To Cook Tri-tip In The Oven
I’m no stranger to tri-tips. I’ve reverse seared them, and I’ve Santa-Maria’d them on the grill. I’ve also cooked them in a crockpot for a long roast. They’ve always been full of flavor and tender in texture.
Tri-tips are good candidates for the grill, for the oven, or even a smoker.
I usually opt for to cook a beef tri-tip roast in the oven. It’s the best way to cook a tri-tip roast during colder months. This oven roasted tri-tip is easy, hands off, and it fills the house with mouthwatering aromas.
Tri-tip roasts usually weigh in at 2 pounds, with a thickness of about 2 inches. Even though it’s considered a lean cut, it should be nicely marbled. The beauty of a tri-tip roast is it takes less time to cook than other roast beef cuts.
How to cook a tri-tip roast in the oven, slow or fast? Simple.
- Step 1: Preheat the oven to 425 degrees. A hot oven like this will sear the outside of the meat quicker leaving the meat tender and juicy on the inside.
- Step 2: Let the tri-tip roast come to room temperature. Some say to slice off the layer of fat from the roast, but I prefer to leave it on for flavor and to keep the roast juicier.
- Step 3: Place the tri-tip roast on a roasting pan fitted with a rack. Using a basting brush, liberally coat the top of the roast with Dijon mustard.If you don’t have a roasting pan, you can use a baking dish, or better yet, a cast-iron skillet.
- Step 4: Cover the roast with fresh stalks of rosemary and thyme, gently pressing the fresh herbs into the mustard. The sticky mustard helps them stay in place.
- Step 5: Place the meat in the oven and roast for 10 minutes. Turn the heat down to 350 and continue roasting to desired doneness. About 20 minutes longer.
- Step 6: Remove the beef tri-tip roast from the oven and tent it with foil. Let is rest for 10 minutes. This will allow the meat to continue to cook while drawing the juices into the meat so they don’t spill out all over the cutting board.
- Step 7: Remove the fresh rosemary and thyme, slice the tri-tip against the grain and serve.

Tips and FAQ’s
There’s really no reason to trim or cut the fat from a tri-tip roast. Leaving the fat will lock in the natural juices and add flavor as it bakes in the oven.
With a cut of meat like a tri-tip, always cut against the grain. Why against the grain? It shortens the muscle fibers and makes it easier to chew. With its triangular shape, the grain of the meat changes direction. Be aware of this and follow the pattern of the meat. Look for the direction the grain is running, and then cut the meat against that pattern. To make it easier, cut the roast in half where the grain changes direction, then carve.
