What is a Tri-Tip Roast?

A tri-tip roast is a lean and tender cut of beef from the bottom sirloin of a steer.  It has a triangular shape, which is where it gets it’s name.  The same cut can also be called bottom sirloin roast or triangle roast.  It is a small roast usually weighing 1 1/2 to 2 pounds.

How to Cook Tri-Tip

Tri-tip is a versatile cut of beef with great flavor.  Rubs, seasonings, and marinades all enhance the tenderness and the flavor of the roast.  A tri-tip roast is delicious roasted or broiled in the oven, or cooked on the grill as in this recipe.  The grill gives the roast an extra smoky flavor and slightly crispy exterior while keeping the inside tender and juicy.

How to Cut Tri-Tip

• Start with a sharp knife and cutting board
• Notice the shape of the tri-tip.  It is shaped kind of like a boomerang.  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.
