This Szechuan Beef brings authentic Chinese restaurant flavor right to your kitchen with perfectly tender beef slices and a sauce that balances sweet, savory, and spicy notes. The marinade is the secret to creating meat that's both flavorful and melt-in-your-mouth tender, while the vibrant sauce delivers that distinctive Szechuan heat.
I first developed this recipe after trying to recreate my favorite Chinese takeout dish that my local restaurant stopped serving. After several attempts, my family now requests this homemade version over any takeout option.
Ingredients
- Flank steak: the ideal cut for stir fry thanks to its rich flavor and tender texture when sliced thinly across the grain
- Soy sauce: provides the foundation of umami flavor that penetrates the meat
- Cornstarch: the secret to creating that tender restaurant style texture by protecting the meat during cooking
- Rice wine: adds subtle sweetness and helps tenderize the beef further
- Asian chili sauce: begins building the signature Szechuan heat profile
- Sesame oil: adds a nutty aroma that elevates the entire dish
- Garlic and ginger powder: delivers convenience without sacrificing flavor
For the Szechuan Sauce
- Oyster sauce: creates rich umami depth that forms the sauce base
- Soy sauce: enhances the savory notes throughout the dish
- Brown sugar: balances the heat with necessary sweetness
- Asian chili sauce: adjust to your desired spice level
- Szechuan peppercorn powder: the critical ingredient providing that distinctive numbing tingle
- Chinese five spice: adds complex aromatic notes that make this authentically Szechuan
- Red pepper flakes: provides visual appeal and additional heat dimension
For the Stir Fry
- Bell pepper and onion: adds color, texture and sweetness to balance the spicy sauce
- Fresh ginger and garlic: provides aromatic foundation that cannot be matched by dried versions
- Vegetable or peanut oil: high smoke point oils perfect for stir frying
Step-by-Step Instructions
- Prepare the Marinade:
- Combine all marinade ingredients in a freezer bag, making sure the cornstarch is fully dissolved with no lumps. Add thinly sliced beef and massage the mixture into the meat, ensuring each piece is coated. Allow to marinate for at least 30 minutes at room temperature or up to 8 hours in the refrigerator for deeper flavor development.
- Mix the Sauce:
- Whisk together all sauce ingredients in a small bowl until the cornstarch is completely incorporated. The sauce should have a uniform color without any white streaks. This can be prepared simultaneously with the marinade and refrigerated until needed, or made just before cooking.
- Sear the Beef:
- Heat your wok or large skillet until it is smoking hot before adding oil. This step is crucial for achieving that coveted restaurant style sear. Cook the beef in batches to prevent overcrowding, which would cause steaming instead of searing. The beef should develop a slight caramelization in just one minute per side. Remember it will continue cooking later, so resist the urge to cook it through now.
- Sauté the Vegetables:
- Using the same hot pan with all those flavorful beef bits, sauté the onions first to develop sweetness. Add the bell peppers next, followed by fresh garlic and ginger at the end to prevent burning these delicate aromatics. The vegetables should remain slightly crisp for textural contrast.
- Combine and Thicken:
- Return the seared beef to the pan with the vegetables. Give your sauce a final whisk before pouring it over everything. The cornstarch will activate in the hot pan, thickening the sauce within minutes as you stir constantly. The sauce should coat the beef and vegetables with a glossy finish when properly thickened.
- Taste and Adjust:
- Before serving, taste the dish and adjust the heat level by adding more chili sauce if desired. The final dish should have a balance of flavors with noticeable heat and that signature Szechuan tingle.

You Must Know
The Szechuan peppercorns are truly what makes this dish special. The first time I served this to my husband, he was amazed by the unique tingling sensation these create on your tongue. It is not just heat but a fascinating numbing quality that makes Szechuan cuisine so distinctive from other Chinese regional cooking styles.
Finding Szechuan Ingredients
Most ingredients for this recipe can be found in the international aisle of standard grocery stores. For specialty items like Szechuan peppercorns and Chinese five spice, Asian markets offer the best quality and value. Online retailers also carry these ingredients if you cannot source them locally. Look for whole Szechuan peppercorns that you can grind yourself for the freshest flavor, or purchase pre-ground for convenience.
Perfect Rice Pairing
This bold and flavorful beef deserves the right rice companion. Jasmine rice works beautifully with its slight floral aroma complementing the spicy beef. For optimal texture, rinse your rice until the water runs clear before cooking to remove excess starch. Allow cooked rice to rest covered for 10 minutes after cooking for fluffy individual grains that will soak up that delicious Szechuan sauce.
Managing the Heat Level
The beauty of making Szechuan beef at home is controlling exactly how spicy you want it. For a mild version that still delivers authentic flavor, reduce the Asian chili sauce to just one teaspoon and eliminate the red pepper flakes. For heat lovers, increase the chili sauce up to three tablespoons and double the red pepper flakes. Remember that the Szechuan peppercorns contribute sensation rather than traditional spicy heat, so adjust accordingly.

Frequently Asked Questions
- → Can I substitute another cut of beef for flank steak?
Yes, you can substitute sirloin, ribeye, or skirt steak. The key is slicing the meat thinly across the grain. For an even more tender result, freeze the beef for 20-30 minutes before slicing to make cutting easier.
- → How can I adjust the spice level?
Control the heat by adjusting the amount of Asian chili sauce (Sambal Oelek) and red pepper flakes. Start with half the recommended amount for milder heat, or increase by 50% for extra spicy. The Szechuan peppercorns provide a numbing sensation rather than heat, so adjust accordingly.
- → What can I substitute for rice wine or sherry?
If you don't have Japanese rice wine (mirin) or dry sherry, you can substitute with an equal amount of dry white wine, apple juice with a splash of vinegar, or chicken broth with a teaspoon of sugar added.
- → Where can I find Szechuan peppercorns and Chinese five spice?
Both ingredients are available in the international aisle of well-stocked supermarkets, Asian grocery stores, or online. If you can't find Szechuan peppercorns, substitute with freshly ground black pepper and a pinch of coriander, though the distinctive numbing quality will be missing.
- → Can I make this dish ahead of time?
You can prepare the marinade, sauce, and slice the vegetables up to 24 hours in advance. The beef can marinate for 2-8 hours in the refrigerator. For best texture, cook just before serving as reheating can make the beef tough and the vegetables soggy.
- → What vegetables can I add to this stir-fry?
This versatile dish works well with broccoli, snow peas, mushrooms, zucchini, or carrots. Just adjust cooking times based on vegetable density - add firmer vegetables earlier and quick-cooking ones later to maintain texture and color.
