Ingredients You’ll Need

For the Marinated Beef

• Beef flank steak: The star of the show, with excellent flavor and texture that stands up well to stir-frying. Sliced thinly against the grain for maximum tenderness.
• Cornstarch: Creates a protective coating on the beef that keeps it tender and helps thicken the sauce.
• Soy sauce: Adds that classic umami flavor and helps tenderize the meat.
• Rice vinegar: Adds brightness and helps break down the proteins in the beef for extra tenderness.
• Egg white: The secret ingredient! Creates a velvety, protective coating on the beef during cooking.
• Sesame oil: Adds a nutty aroma and flavor that’s distinctive in Asian cooking.
• Garlic: Provides aromatic depth to the marinade.
• Ginger: Adds a warm, spicy note that pairs perfectly with beef.

For the Vegetables

• White onion: Provides sweetness and texture once cooked.
• Bok choy: Adds a delightful crunch and freshness to balance the rich beef.

For the Sauce

• Oyster sauce: The foundation of the sauce, delivering deep umami flavor and natural sweetness.
• Light soy sauce: Enhances the savory notes without overpowering the dish.
• Sugar: Balances the saltiness with a touch of sweetness.
• Sesame seeds: Optional garnish that adds a pleasant crunch and visual appeal.
• Green onions: Adds color, freshness, and a mild oniony bite as a garnish.

Variations

Want to customize this dish? Here are some delicious options:

• Protein Swap: Use chicken breast, pork tenderloin, or even firm tofu instead of beef.

• Extra Umami: Add a tablespoon of hoisin sauce for a deeper, more complex flavor.

How to Make Beef in Oyster Sauce

Step 1: Marinate the Beef

Slice your beef thinly against the grain and place in a resealable bag. Add cornstarch, soy sauce, rice vinegar, beaten egg white, sesame oil, diced garlic, and grated ginger. Seal the bag and massage the marinade into the beef until evenly coated. Refrigerate for at least 20 minutes while you prep the other ingredients.

Step 2: Cook the Beef

Heat a large skillet over medium-high heat and add a generous drizzle of vegetable oil. When hot and shimmering, add the marinated beef in a single layer (work in batches to avoid overcrowding). Cook for just one minute on each side until the outside is browned but the inside remains tender. Transfer to a paper towel-lined plate.

Step 3: Cook the Vegetables

Add another drizzle of oil to the same pan. Toss in the chopped white onion and stir-fry for 1-2 minutes until slightly softened. Add the bok choy and continue cooking for 2-3 minutes until the vegetables are crisp-tender with bright green leaves and slightly softened stalks.

Step 4: Combine and Sauce

Return the beef to the pan with the vegetables. Pour in the oyster sauce, soy sauce, and sugar. Toss everything together quickly, cooking for just about a minute until the sauce thickens slightly and coats all ingredients evenly.

Step 5: Serve

Transfer to a serving platter or individual plates over steamed rice or stir-fried noodles. Sprinkle with sesame seeds and sliced green onions for an extra pop of color and flavor.

Pro Tips for Making the Recipe

• Freeze the beef for 20 minutes before slicing to make it easier to cut into thin, even strips.
• Don’t skip the marinade time – those 20 minutes are crucial for developing flavor and tenderness.
• Cook in batches to ensure your beef gets a nice sear instead of steaming in an overcrowded pan.
• Have everything prepped and ready before you start cooking – this dish moves quickly once you begin.
• Cut bok choy stalks and leaves separately – add the stalks first as they take longer to cook than the leaves.

How to Serve

This versatile dish pairs beautifully with several sides:

Main Pairing

Serve over steamed jasmine rice or stir-fried noodles to soak up all that delicious sauce.

Side Dishes

Complement with simple sides like steamed broccoli, a clear Chinese soup, or spring rolls.

Drink Pairing

This goes wonderfully with a light jasmine tea or a crisp lager beer that won’t overpower the delicate flavors.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors often develop and taste even better the next day!

Freezing

This dish can be frozen for up to 2 months. For best results, slightly undercook the vegetables before freezing, as they’ll continue cooking when reheated.

Reheating

Gently reheat in a skillet over medium heat with a splash of water to revive the sauce. Microwave on 70% power, stirring halfway through, to prevent the beef from becoming tough.

FAQs

Can I use a different cut of beef for this recipe?
Absolutely! While flank steak is traditional, ribeye or sirloin work beautifully too. The key is cutting the meat thinly against the grain and not overcooking it. For budget options, chuck steak can work if sliced very thin and not overcooked.

What can I substitute for oyster sauce if I don’t have it?
If you don’t have oyster sauce, mix 2 tablespoons of hoisin sauce with 1 teaspoon of soy sauce as a substitute. It won’t be identical but provides a similar savory-sweet profile. For vegetarians, look for mushroom-based “vegetarian oyster sauce” in Asian markets.

How do I prevent my beef from becoming tough?
Three key steps: marinate with cornstarch and egg white (this technique is called “velveting”), slice thinly against the grain, and cook quickly at high heat for just about a minute per side. Overcooking is the enemy of tender beef in stir-fries.

Is this recipe gluten-free?
Standard oyster sauce and soy sauce contain wheat. For a gluten-free version, use tamari instead of soy sauce and look for gluten-free oyster sauce (available at specialty stores). Also double-check your cornstarch is processed in a gluten-free facility.
