To Grill… Heat grill to medium-high (for tri-tip, heat to medium). Oil the grate to prevent sticking (swipe with an oil-moistened paper towel, held with tongs). Grill the steak to the desired doneness. (See How to Cook Beef for more details.)
Or Sear… Heat 1 teaspoon oil in a large skillet over medium-high heat. Cook the steak to the desired doneness. (For tri-tip, you will also need to roast for the suggested time.)
Or Broil…* Heat broiler to high. Broil the steak to the desired doneness.
Then Let It Rest Whichever method you use, let your steak rest on a cutting board, loosely tented with foil, for about 5 minutes before slicing. That time allows the meat fibers to relax and plump with juices that would spill onto the board if you sliced too soon.
*Unless broiling instructions are given for a cut of meat, broiling is not recommended. Why? Thinner cuts of meat won’t brown, and if you have a gas broiler, the fattier cuts can start a fire.
