Tri Tip Roast

This grilled Tri Tip Roast is perfectly tender. The marinade gives the tri-tip so much flavor, there is no need for steak sauce.  *Please note that the roast will need to marinade 6 to 12 hours before grilling.

Notes

*Prep and cooking time does not include the 6 to 12 hours the roast will need to marinate in the refrigerator.
*Use a meat thermometer to cook tri tip to your preference. We cooked it to rare at 140 degrees F then covered it with foil to rest and it cooked to a perfect medium rare. 
To cut tri tip roast:
  • Start with a very sharp knife and cutting board.
  • Notice the shape of the tri tip. Close to the center of the cut, or the boomerang shape, there is a seam of fat. On each side of the seam, the grain of the meat runs a different direction. The "grain" is the direction that the muscle fibers run. It looks like lines or stripes in the meat.
  • The first cut of the tri tip should be along the seam at the center of the meat. This is the point where you can see that the grain of the meat goes one direction on one side, and another direction on the other side.
  • Look at both halves and determine which way the grain is going. Slice the meat in thin slices that go against (across or perpendicular to) the grain. Slicing meat against the grain cuts through the muscle fibers and makes the meat more tender and easier to chew.
  • Layer the slices on a serving platter.
