Ingredients
For this recipe, you’ll need:
- Thinly sliced beef, such as flank steak or sirloin, for tenderness and flavor
- Cornstarch, to create the signature crispy coating on the beef
- Soy sauce, for a savory umami punch
- Egg, to help bind the coating to the beef
- Vegetable oil, for frying
- Fresh garlic and ginger, finely minced for aromatic depth
- Red chillies, thinly sliced to add heat and color
- Green onions, sliced for freshness and garnish
- Brown sugar, to balance the heat with sweetness
- Rice vinegar, adding a bright acidity to the sauce
- Sesame oil, for a nutty, fragrant finish
Feel free to tweak this list by adding vegetables like bell peppers or adjusting the chili quantity to suit your heat preference.
Preparation
Begin by slicing the beef thinly against the grain to maximize tenderness. Marinate the beef in a blend of soy sauce, cornstarch, and beaten egg for about 30 minutes. This process not only flavors the meat but also tenderizes it and prepares it for frying by ensuring the cornstarch coating sticks well. While the beef marinates, prepare the sauce by mixing minced garlic, ginger, sliced red chillies, soy sauce, brown sugar, rice vinegar, and sesame oil, adjusting ingredients as needed for your desired balance of sweetness and spice.
Once marinated, lightly dust each beef slice with cornstarch to create a crispy outer layer. Be sure to shake off any excess to prevent clumping during frying.
Making the Sauce
Heat a splash of vegetable oil in a pan and sauté the minced garlic, ginger, and red chillies until they release their fragrant aroma. Next, add the pre-mixed sauce ingredients to the pan. Cook the mixture, stirring regularly, until the brown sugar dissolves completely and the sauce thickens just slightly, becoming glossy and ready to coat the beef perfectly.
Cooking Process
Heat oil in a deep fryer or a deep pan to around 350°F (180°C). Fry the cornstarch-coated beef slices in small batches, making sure not to overcrowd the pan, for approximately 2 to 3 minutes or until the beef turns golden brown and crunchy. Drain the fried beef on paper towels to remove excess oil.
Once all the beef has been fried, toss it immediately in the warm sauce to ensure every piece is evenly coated. Finish the dish with a garnish of sliced green onions, which add a fresh, crisp contrast to the rich, saucy beef.
Serving Suggestions
Serve your Spicy Crispy Beef Stir-Fry piping hot for the best experience. It pairs wonderfully with steamed jasmine rice or stir-fried noodles to soak up the flavorful sauce. For a full meal, combine it with classic Chinese appetizers like spring rolls, dumplings, or steamed vegetables for a delightful and satisfying feast.
Health Considerations
While undeniably indulgent, Spicy Crispy Beef is best enjoyed in moderation due to the frying process and the sugar content in the sauce. To lighten the dish, opt for lean cuts of beef and reduce the amount of oil used when frying. Alternatively, consider shallow frying or air frying for a lower-fat option.

Tips and Tricks
- Ensure your frying oil is hot enough before adding the beef to get that perfect crispy crust.
- Avoid overcrowding the pan to maintain the oil temperature and prevent soggy beef.
- For a thicker sauce, incorporate a cornstarch slurry (a mixture of cornstarch and water) and simmer until the sauce coats the beef beautifully.
- Control the spiciness by adjusting the number of chillies or removing seeds to tone down the heat.
- Marinating the beef for longer than 30 minutes can enhance tenderness and flavor even more.
FAQs
Can I use chicken instead of beef?
Yes! Thinly sliced chicken breast or thighs work well and absorb the sauce beautifully for a delicious variation.
How do I store leftovers?
Keep any leftovers in an airtight container in the fridge for up to 2 days. Reheat gently in a pan or microwave to maintain texture and flavor.
Is this dish gluten-free?
It can be made gluten-free by substituting soy sauce with tamari or another gluten-free soy sauce alternative.
How spicy is the dish?
The heat level can be adjusted by varying the amount of chillies used or by removing their seeds for a milder taste.
Can I freeze Spicy Crispy Beef?
Freezing is possible, but the texture might soften slightly after thawing and reheating. It’s best enjoyed fresh for optimal crunch.
