A great stir fry is all about high heat and fast cooking. The beef gets a quick sear while the peppers stay crisp-tender, and a simple sauce ties everything together in minutes.

This is the weeknight dinner you will come back to again and again. Prep everything before you start cooking, because once the wok is hot, things move fast.

Why This Recipe Works

Velveting the beef with a touch of cornstarch and soy sauce before cooking creates a silky coating that keeps the meat juicy even at high heat.

Ingredients

  • 1 lb flank steak, thinly sliced against the grain
  • 2 bell peppers (any color), sliced
  • 1 small onion, sliced
  • 3 tbsp soy sauce
  • 1 tbsp cornstarch
  • 1 tbsp sesame oil
  • 2 cloves garlic, minced
  • 1 tbsp fresh ginger, minced

Instructions

  1. 1

    Toss sliced beef with 1 tbsp soy sauce and cornstarch. Let sit 10 minutes while you prep vegetables.

  2. 2

    Mix remaining 2 tbsp soy sauce, 1 tbsp rice vinegar, 1 tsp sugar, and sesame oil in a small bowl for the sauce.

  3. 3

    Heat 1 tbsp vegetable oil in a wok or large skillet over high heat until smoking. Sear beef in a single layer for 1-2 minutes. Remove.

  4. 4

    Add another tbsp oil. Stir fry peppers and onion for 2-3 minutes until crisp-tender. Add garlic and ginger, cook 30 seconds.

  5. 5

    Return beef to the wok, pour sauce over, and toss everything together for 30 seconds until glazed.

  6. 6

    Serve immediately over steamed rice.

Serving Suggestions

Ways to Serve This Dish

  • Serve over steamed jasmine or sticky rice

  • Pair with a side of pickled vegetables or kimchi

  • Add a drizzle of sesame oil and toasted sesame seeds for extra flavor

Substitutions

Flank steakSirloin

Sirloin is a good budget alternative. Slice it thin against the grain.

Soy sauceCoconut aminos

Coconut aminos are less salty and soy-free.

Fresh gingerGround ginger

Use 1/2 tsp ground ginger in place of 1 tbsp fresh.

Tips & Storage

Pro Tips

  • Freeze the steak for 20 minutes before slicing for paper-thin cuts.

  • Have everything prepped and ready before turning on the heat.

  • Do not overcrowd the wok — cook beef in batches if needed.

  • Use the highest heat your stove can produce for proper wok char.

Storage

Store in an airtight container for up to 3 days. Keep rice separate.

Reheating

Reheat in a hot skillet or wok for 2-3 minutes. Avoid the microwave for best texture.

Frequently Asked Questions

What is velveting?
Coating meat in cornstarch and soy sauce before cooking. It creates a protective layer that keeps the beef tender and juicy.
Can I use other vegetables?
Snow peas, broccoli, zucchini, and snap peas all work well. Cut everything to a similar size.
Can I use a regular skillet?
Yes, just make sure it is very hot. A cast iron skillet holds heat well for stir frying.
