Method
Marinate the beef
- Combine 2 tablespoons soy sauce, 1 tablespoon brown sugar, and cornstarch, then mix until uniform. Toss with the thin-sliced flank steak and let it marinate for 30 minutes.
Sear the beef on the Blackstone
- Heat the Blackstone griddle to high heat until hot. Add 2 tablespoons oil and spread it into an even layer.
- Cook the beef in batches for 2-3 minutes per side, flipping only once or twice, until deeply seared. Transfer the beef to a plate and repeat with any remaining slices.
Cook the broccoli and sauce
- Add the remaining oil to the griddle, then cook the broccoli for 4-5 minutes until tender-crisp. Keep it moving so the florets stay vibrant green.
- Push broccoli to one side, add garlic and ginger, and cook for 30 seconds until fragrant. Stir to combine.
- Add the remaining soy sauce, oyster sauce, brown sugar, and beef broth to the griddle. Bring to a quick bubble and stir to dissolve any glaze.
- Return the seared beef to the griddle and toss everything for 2 minutes until glossy and coated. Finish by sprinkling with sesame seeds and serve immediately.
Notes
Pro tip: Slice the flank steak thin against the grain so it stays tender during high-heat griddling. Refrigerate leftovers in a sealed container for up to 3 days; reheat in a hot skillet or on the griddle until warmed through. Freezing isn’t recommended because broccoli texture softens. For a gluten-free swap, use tamari instead of soy sauce.
