In a mixing bowl, whisk together all of the marinade ingredients until combined.
Add the sliced steak to the marinade mixture and toss until fully coated. Cover with plastic wrap and refrigerate for at least 30 minutes or up to 2 hours.
Preheat the oven to 435°F. Line a 9x13” or larger baking sheet with parchment paper.
Using tongs, transfer the steak to the baking sheet.
Add the broccoli to the marinade and toss until well coated. Transfer the broccoli to the baking sheet and spread the steak and broccoli in a single layer.
Spoon any remaining marinade over the entire pan.
Bake for 12 to 14 minutes, or until the steak is cooked through.
Switch the oven to broil and cook for an additional 2 minutes. Watch to ensure it does not burn.
Remove from the oven. Serve with rice, and garnish with sesame seeds, if desired. Pour any remaining juices over the plated steak and broccoli. Enjoy!
Notes
Baking time may vary depending on the thickness of the steak.
Flank steak works great for this recipe!
Store leftovers in an airtight container for up to 3 days or 3 months in the freezer.
When storing, make sure the beef and broccoli cools completely before sealing to prevent condensation.
