Ingredients
Directions
Heat sesame oil in a small skillet over medium-high heat. Add sesame seeds; cook and stir until golden brown, about 1 minute. Transfer seeds and oil immediately to a large glass or ceramic baking dish.
Add onions, soy sauce, lemon juice, sugar, garlic, and peppercorns to sesame mixture; stir until marinade is combined. Add steak to marinade and toss to evenly. Cover the baking dish with plastic wrap; marinate in the refrigerator, flipping often, 4 hours to overnight.
Preheat an outdoor grill for medium-high heat and lightly oil the grate.
Remove steak from marinade, shake off excess, and discard remaining marinade.
Cook on the preheated grill until steak starts to firm and turns reddish-pink and juicy in center, about 10 minutes per side. An instant-read thermometer inserted into center should read 130 degrees F (54 degrees C) for medium-rare. Transfer steak to a plate, cover with aluminum foil, and rest before slicing against the grain, about 10 minutes.
Cook's Note:
My wife takes the onions from the marinade, cooks them in a skillet over low heat until caramelized, and serves them over the sliced London broil.
