- 1 tablespoon oyster sauce
- 1 tablespoon Shaoxing wine (or dry sherry)
- 1 teaspoon cornstarch
- 1/2 teaspoon baking soda
Stir Fry:
- 2 tablespoons vegetable oil (divided)
- 2 medium yellow onions, sliced

- 1/4 cup beef broth or water
- 1 teaspoon sesame oil

How to Make Chinese Beef and Onion Stir Fry Recipe:
Step-by-Step Instructions:
Step 1: Prepare the Marinated Beef Place the thinly sliced flank steak in a medium bowl. Add soy sauce, oyster sauce, Shaoxing wine, cornstarch, and baking soda. Mix thoroughly with your hands or a fork, ensuring every piece of beef is well-coated. Let the beef marinate for at least 15 minutes at room temperature, or up to 2 hours in the refrigerator for deeper flavor penetration.
Step 2: Prepare Your Ingredients While the beef marinates, slice your onions into thin half-moons and mince the garlic. Having everything prepped and ready is crucial for successful stir-frying, as the cooking process happens very quickly.
Step 3: Heat Your Wok or Pan Heat 1 tablespoon of vegetable oil in a large wok or heavy-bottomed skillet over high heat until it begins to smoke slightly. This high temperature is essential for achieving the characteristic “wok hei” or breath of the wok flavor.
Step 4: Cook the Beef Add the marinated beef to the hot oil in a single layer. Let it sear undisturbed for 1-2 minutes to develop a nice crust, then stir-fry for another 2-3 minutes until the beef is just cooked through. Remove the beef from the pan and set aside on a plate.
Step 5: Stir-Fry the Onions Add the remaining tablespoon of oil to the same pan. Add the sliced onions and stir-fry for 3-4 minutes until they begin to soften and develop some caramelization around the edges. The onions should still retain some crunch.
Step 6: Add Aromatics Push the onions to one side of the pan and add the minced garlic to the empty space. Stir-fry the garlic for 30 seconds until fragrant, then mix it with the onions.
Step 7: Combine and Season Return the cooked beef to the pan along with any accumulated juices. Add the sugar, beef broth, and a generous grinding of black pepper. Stir everything together for 1-2 minutes until the liquid reduces slightly and coats the ingredients.
Step 8: Finish and Serve Remove the pan from heat and drizzle with sesame oil. Toss everything together one final time. Transfer to a serving platter and garnish with chopped green onions if desired. Serve immediately while hot.
Helpful Tips:
Beef Preparation: Always slice flank steak against the grain to ensure maximum tenderness. The baking soda in the marinade is a professional technique that breaks down proteins, creating incredibly tender beef that won’t become tough during high-heat cooking.
Temperature Control: Maintain high heat throughout the cooking process. If your pan isn’t hot enough, the ingredients will steam rather than stir-fry, resulting in soggy vegetables and tough meat.
Timing is Everything: Don’t overcook the beef. It should be just cooked through and still slightly pink in some areas when you remove it from the pan. It will finish cooking when you return it to the pan with the onions.
Oil Selection: Use oils with high smoke points like vegetable, canola, or peanut oil for stir-frying. Avoid olive oil as it will burn at the high temperatures required.
Onion Texture: Cook the onions until they’re tender but still have some bite. Overcooked onions will become mushy and lose their sweetness.

This Chinese Beef and Onion Stir Fry Recipe showcases the fundamental techniques of Cantonese cooking. The key to success lies in the preparation and timing. The baking soda marinade is a restaurant secret that home cooks often overlook, but it makes an enormous difference in the final texture of the beef. The sugar added to the onions helps accelerate caramelization, creating deeper flavors in a shorter cooking time.
Notes:

Ingredient Substitutions: If Shaoxing wine isn’t available, dry sherry or even rice wine vinegar works well. For a gluten-free version, use tamari instead of soy sauce and check that your oyster sauce is gluten-free.
Beef Alternatives: While flank steak is ideal, you can substitute with sirloin, ribeye, or even beef tenderloin. Just adjust cooking times accordingly, as more tender cuts may cook faster.
Make-Ahead Tips: The beef can be marinated up to 24 hours in advance. All vegetables can be prepped earlier in the day and stored in the refrigerator.
Scaling the Recipe: This recipe doubles easily for larger crowds. Just make sure not to overcrowd your pan, or cook in batches to maintain proper temperature.
Frequently Asked Questions:
Q: Why is my beef tough despite following the recipe? A: The most common cause is not slicing against the grain or cooking at too low a temperature. Also, ensure you’re not overcooking the beef in the initial searing stage.
Q: Can I make this recipe with frozen beef? A: Fresh beef works best, but if using frozen, ensure it’s completely thawed and patted dry before marinating. Excess moisture will prevent proper searing.
Q: What’s the best way to slice beef for stir-fry? A: Partially freeze the beef for 30 minutes to firm it up, making it easier to slice thinly. Always cut against the grain at a slight angle for maximum tenderness.
Q: Can I add other vegetables to this recipe? A: Absolutely! Bell peppers, snap peas, or broccoli work well. Add harder vegetables first and softer ones later to ensure even cooking.
Q: Is this recipe spicy? A: This base recipe isn’t spicy, but you can add sliced chilies or chili oil to taste during the cooking process.
Storage Instructions:
Refrigerator Storage: Store leftover Chinese Beef and Onion Stir Fry in an airtight container in the refrigerator for up to 3 days. The flavors actually develop more overnight, making leftovers quite delicious.
Reheating: Reheat in a hot skillet or wok over medium-high heat for 2-3 minutes, stirring frequently. Avoid microwaving as it can make the beef tough and the onions mushy.
Freezing: While possible, freezing isn’t recommended as the texture of both beef and onions deteriorates significantly when thawed.
Meal Prep: This dish works well for meal prep when stored separately from rice or noodles. Combine just before reheating for best results.
