Ingredients

Steak

2½ pounds beef top sirloin or flank steak

Marinade

½ cup low-sodium soy sauce (or tamari for gluten-free)
2 tablespoons olive oil
1 teaspoon minced garlic
¼ teaspoon freshly ground black pepper

Teriyaki Sauce

⅓ cup low-sodium soy sauce (or tamari for gluten-free)
⅓ cup mirin (sweet rice wine)
2 tablespoons sugar
1 tablespoon sesame oil
½ teaspoon finely grated fresh ginger
½ teaspoon minced garlic
⅓ cup water
2 teaspoons cornstarch

Garnish

2 tablespoons sesame seeds
3–4 green onions, thinly sliced

Instructions

Marinate the Steak

Place the steak in a large resealable plastic bag.
In a small bowl, combine the marinade ingredients and pour over the steak. Seal the bag and refrigerate for 1 to 6 hours.

Grill the Steak

Preheat the grill to medium-high heat. Grill the steak for 6–7 minutes per side, or until the internal temperature reaches 145°F for medium-rare to medium. Cooking times may vary depending on the steak’s thickness.
Transfer the steak to a cutting board and let it rest for 10 minutes before slicing.

Prepare the Teriyaki Sauce

In a small saucepan, combine soy sauce, mirin, sugar, sesame oil, ginger, and garlic. Heat over medium-low heat.
Mix cornstarch with water until smooth and add to the sauce. Cook, stirring constantly, until slightly thickened. Remove from heat and set aside.

Serve

Slice the steak thinly across the grain. Drizzle with some Teriyaki Sauce, then garnish with sesame seeds and green onions. Serve with remaining sauce on the side.
