Why These Ingredients Work So Well Together

This classic stir-fry combo creates bold flavor and perfect texture:

  • Beef sirloin: Lean and tender when thinly sliced—cornstarch “velvets” it for silky softness.
  • Soy sauce & cornstarch: Marinade tenderizes beef and helps create glossy sauce.
  • Vegetables (bell peppers, broccoli, carrots, onions): Colorful mix—harder veggies add crunch, softer ones sweetness.
  • Garlic & ginger: Aromatic base that infuses everything with savory warmth.
  • Sauce (oyster sauce, soy sauce, sesame oil, sugar): Umami-rich, glossy coating—oyster adds depth, sesame nutty aroma, sugar balances.
  • Rice: Soaks up all the delicious sauce.

High heat + quick cooking = vibrant colors, crisp veggies, and juicy beef.

Ingredients

  • 1 lb (450g) beef sirloin or flank steak, thinly sliced against the grain
  • 2 tablespoons soy sauce (for marinade; plus 2 more for sauce)
  • 1 tablespoon cornstarch (for marinade)
  • Vegetables (about 4–5 cups total):
  • 1 bell pepper (red, yellow, or green), sliced
  • 2 cups broccoli florets
  • 2 medium carrots, thinly sliced
  • 1 large onion, sliced into wedges
  • 3 cloves garlic, minced
  • 1-inch piece fresh ginger, thinly sliced or minced
  • Sauce:
  • 2 tablespoons oyster sauce
  • 2 tablespoons soy sauce
  • 1 teaspoon sesame oil
  • 1 teaspoon sugar (or honey)
  • 2–3 tablespoons neutral oil (like vegetable or avocado) for stir-frying
  • Cooked rice (white, brown, or cauliflower rice) for serving
  • Optional: green onions or sesame seeds for garnish, red pepper flakes for heat

Step-by-Step Instructions

  1. Marinate the beef — In a bowl, toss sliced beef with 2 tablespoons soy sauce and cornstarch until coated. Let marinate 15 minutes while prepping veggies.
  2. Prepare the sauce — In a small bowl, whisk together oyster sauce, remaining 2 tablespoons soy sauce, sesame oil, and sugar. Set aside.
  3. Heat the wok — Place a wok or large skillet over high heat. Add 1 tablespoon oil and swirl to coat. When smoking hot, add beef in a single layer (in batches if needed). Stir-fry 1–2 minutes until browned. Remove to a plate.
  4. Stir-fry aromatics & hard veggies — Add another tablespoon oil if needed. Toss in garlic, ginger, carrots, and broccoli. Stir-fry 3–4 minutes until bright and starting to soften.
  5. Add softer veggies & beef — Add bell pepper and onion. Stir-fry 2 minutes, then return beef and any juices to the pan.
  6. Finish with sauce — Pour in the prepared sauce. Toss everything 2 more minutes until sauce thickens, coats evenly, and veggies are crisp-tender. Serve immediately over hot rice!

Pro Tips for Restaurant-Quality Stir-Fry

  • Slice beef thinly against the grain—partially freeze for easier cutting.
  • High heat is essential—get your pan smoking hot for wok hei flavor.
  • Prep everything before starting—stir-frying moves fast!
  • Cook beef in batches—overcrowding steams instead of sears.
  • Don’t overcook veggies—crisp-tender is the goal.
  • Taste sauce and adjust—more sugar for sweeter, soy for saltier.
