Scallion Beef

My son has a completely different palate than us. While I cook mostly chicken for dinner, little G avoids it every time I try to sneak some into his rice. He loves beef, and his favorite is Korean Kalbi, so he naturally prefers beef stir fries like my Ginger and Scallion Beef or this scallion beef. Other than everyone’s favorite Mongolian Beef, I often change my recipe to incorporate onion into the mix to make this super yummy scallion beef.

I think it makes the overall dish so much tastier. Onion imparts a sweet flavor once it is caramelized, adding extra texture to this scallion beef recipe. For Chinese recipes, it is very important to velvet the protein so every bite is silky smooth, just like Sesame Beef and Beef and Broccoli. A simple cornstarch marinade seals in the juices so every bite is inviting.

Sidenote: This recipe is a classic of Cantonese home cooking, often referred to as Cong Bao Niurou (葱爆牛肉). In Mandarin, Cong (葱) means scallion, Bao (爆) refers to the high heat explosive stir-frying technique, and Niurou (牛肉) is beef. This method flash cooks the meat to keep it tender while charring the aromatics.

Secrets To Extra Tender And Juicy Beef

I have made this stir-fry hundreds of times and these specific steps are what ensure every single slice of beef is incredibly juicy and tender.

• The Grain Direction: To get that signature tenderness, I always look at the lines in the beef and slice strictly against the grain. This shortens the fibers so the meat stays delicate and easy to bite, even after being seared in a hot wok.
• The Velveted Texture: The real secret to that silky restaurant feel is the cornstarch in the marinade. It creates a thin barrier that protects the beef from the high heat, keeping it moist and preventing it from becoming tough or dry.
• The Searing Phase: I always sear the beef in a very hot wok first. You want to see the edges brown quickly while the center stays slightly pink. This locks in the juices and creates a savory crust that helps the sauce cling to every piece of meat.
• The White Pepper Kick: I never skip the white pepper in this dish. It provides a distinct, floral heat that is much more traditional for this flavor profile than black pepper. It enhances the savoriness of the beef without overpowering the aroma of the scallions.
• The Scallion Layering: I cut my scallions into long strips to match the shape of the beef. Adding them at the very end keeps them bright and snappy, providing a fresh contrast to the rich, tender meat.

Ingredients You’ll Need

• Beef
• Cornstarch
• Shaoxing wine
• Onion
• Scallions

Pro Tip #1: Why I Use Beef Tenderloin
I go for beef tenderloin because it is the most premium, lean cut for quick cooking. It does not have tough connective tissue, which makes it ideal for high heat stir-frying where you want the meat to stay juicy. If you want a more affordable option, flank steak or sirloin are great substitutes as long as you slice them very thin against the grain.

Pro Tip #2: Shaoxing Wine vs. Dry Sherry
I use Shaoxing wine because it is the secret to that authentic restaurant aroma. It helps tenderize the meat and adds a nutty depth. If you cannot find it, dry sherry is the best substitute. Avoid “cooking wines” from the grocery store as they contain too much salt.

Pro Tip #3: Why I Use Yellow Onion
I prefer yellow onion because it has a high sugar content that caramelizes beautifully. I do not recommend using red onion for this dish; it tends to bleed color into the sauce and has a sharper bite that distracts from the scallions.

Chinese Brown Sauce

• Oyster sauce
• Soy sauce
• Dark soy sauce
• Sesame oil
• White pepper

Pro Tip #1: The Best Soy Sauces And Dark Soy Sauce
I recommend using a high quality light soy sauce like Lee Kum Kee or Kikkoman. These provide a clean, salty punch without a chemical aftertaste. For the dark soy sauce, I always reach for Lee Kum Kee Premium Dark Soy Sauce. It provides that deep, mahogany restaurant look and a hint of caramel sweetness.

Pro Tip #2: Why White Pepper Is Best
I never skip white pepper because it provides a sharp, floral heat traditional in Chinese cooking. Avoid using black pepper in this dish; it has a woody flavor that can make the sauce look “dirty” and muddles the clean, authentic flavors of the beef and scallions.

Pro Tip #3: Don’t Skip The Sugar
I add a small amount of sugar to the sauce to bridge the flavors. It rounds out the saltiness of the soy sauce and oyster sauce, creating a well balanced glaze that is not overly salty.
