Ingredients
- 12 oz (340 g) flank steak, thinly sliced against the grain
- 2 cups (150 g) broccoli florets
- 2 tablespoons vegetable oil, divided
- 3 cloves garlic, minced
- 1 tablespoon fresh ginger, minced
- 3 tablespoons soy sauce (use tamari for gluten-free)
- 1 tablespoon oyster sauce
- 1 tablespoon cornstarch
- 1/2 cup (120 ml) beef broth or water
- 1 teaspoon sesame oil
- 1 tablespoon brown sugar
- 1/4 teaspoon crushed red pepper flakes (optional)
- Salt and pepper to taste
Instructions
- Prepare the beef and sauce In a medium bowl, toss the sliced flank steak with cornstarch, salt, and pepper. In a separate bowl, mix soy sauce, oyster sauce, beef broth, brown sugar, sesame oil, and red pepper flakes; set aside.
- Cook the broccoli Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add broccoli florets and stir-fry for 3-4 minutes until bright green and crisp-tender. Remove broccoli and set aside.
- Stir-fry the beef Add the remaining 1 tablespoon of oil to the skillet. Add minced garlic and ginger; stir-fry until fragrant, about 30 seconds. Add the beef and cook for 2-3 minutes, stirring frequently, until no longer pink and browned.
- Combine and finish Return the broccoli to the skillet with the beef. Pour in the prepared sauce mixture. Stir well and cook for 2-3 minutes until the sauce thickens and coats beef and broccoli. Remove from heat.
Helpful Tips
- Slice the beef thinly against the grain to ensure tenderness.
- Use a high smoke point oil like vegetable or canola for stir-frying.
- Adjust the garlic and ginger amounts to taste for more or less pungency.
- Serve immediately for the best texture; broccoli will soften if reheated too long.
- For gluten-free, use tamari instead of soy sauce and check oyster sauce ingredients.
Storage and Make-Ahead
Cool leftovers promptly within 2 hours and store in an airtight container in the refrigerator for up to 3 days.
