🛒 Ingredients
- 1/2 cup low-sodium soy sauce
- 1/4 cup beef broth (or water)
- 2 tablespoons brown sugar (adjust to taste)
- 1 tablespoon oyster sauce
- 1 tablespoon hoisin sauce (optional, for sweetness and depth)
- 2 teaspoons sesame oil
- 2 tablespoons cornstarch
- 3 tablespoons cold water (to mix with cornstarch)
- 2 cloves garlic, minced
- 1 teaspoon fresh ginger, grated (or 1/4 tsp ground ginger)
- Pinch of red pepper flakes (optional, for heat)
🧑🍳 Instructions
- Make cornstarch slurry: In a small bowl, mix cornstarch and cold water until smooth.
- Combine sauce: In another bowl, whisk together soy sauce, beef broth, brown sugar, oyster sauce, hoisin sauce (if using), sesame oil, garlic, ginger, and red pepper flakes.
- Add slurry: Stir the cornstarch mixture into the sauce until well combined.
- Cook: Add the sauce to your stir fry pan with beef and broccoli. Simmer until thickened and glossy (about 2–3 minutes).
💡 Tips
- Slice the beef thinly against the grain for the most tender result.
- Don’t overcook the broccoli – blanch it or steam briefly for vibrant color and a crisp-tender texture.
- Use cold water for the cornstarch slurry to avoid lumps.
- For a glossy, thick sauce, cook it for a minute or two after adding to your pan.
