Whisk together 1 cup low-sodium beef broth, ½ cup low-sodium soy sauce, ⅓ cup dark brown sugar, 1 tablespoon sesame oil, and 3 teaspoons minced garlic in a medium bowl.

Place 1 ½ pounds boneless beef chuck roast (cut into ¼-inch strips) in a 4-7-quart slow cooker and pour the sauce over it. Toss to coat the meat thoroughly.

Set the slow cooker to LOW and cook for 2.5-3.5 hours.

About an hour before the cook time is finished, remove ¼ cup of the cooking liquid and whisk it with 2 tablespoons of cornstarch in a small bowl. Slowly stir this mixture back into the slow cooker.

At the final 30 minutes of cook time, add 1 (12-ounce) bag of frozen broccoli florets to the slow cooker and stir to incorporate. Cover and continue cooking. For firmer broccoli, partially thaw it before adding, or add closer to 1 hour left in the cooking process.

Garnish with green onions and sesame seeds if desired, and serve with white rice.
