Lamb Stir Fry Recipe: Quick, Savory and Full of Vegetables

This lamb stir fry pairs tender strips of lamb with crisp vegetables in a glossy ginger, garlic, and soy sauce. It is Chinese-inspired rather than a claim to one regional or family style, and its quick cooking keeps the vegetables lively while the savory sauce brings everything together.

Ingredients

1 lb (450 g) boneless lamb leg or loin, trimmed of excess fat
1 tbsp (15 ml) light soy sauce, for seasoning the lamb
1 tbsp (15 ml) Shaoxing wine or dry sherry, for seasoning the lamb
2 tsp (5 g) cornstarch, divided between the lamb and sauce
¼ tsp (0.5 g) ground black pepper
2 tbsp (30 ml) light soy sauce, for the stir-fry sauce
1 tbsp (15 ml) oyster sauce
1 tbsp (15 ml) water
1 tsp (4 g) packed brown sugar
½ tsp (2.5 ml) toasted sesame oil
2 tbsp (30 ml) neutral high-heat oil, such as canola or peanut oil, divided
1 medium red bell pepper, about 5 oz (150 g), cored and thinly sliced
1 small yellow onion, about 4 oz (110 g), thinly sliced
2 cups (180 g) small broccoli florets
3 scallions, about 1½ oz (45 g), cut into 1-inch (2.5 cm) pieces; separate white and green parts
1 tbsp (6 g) finely grated or minced fresh ginger
3 garlic cloves, about 9 g, finely chopped
¼ tsp (0.5 g) red pepper flakes, optional

Instructions

Prepare the lamb and vegetables. Pat the lamb dry and cut it across the grain into strips about ½ inch (1.3 cm) thick. Cutting across the grain shortens the muscle fibers, making each bite easier to chew. In a bowl, toss the lamb with 1 tablespoon (15 ml) soy sauce, the Shaoxing wine, 1 teaspoon (2.5 g) cornstarch, and black pepper. Leave it while you prepare the vegetables; this is a brief seasoning step, not a required long marinade. Mix the remaining 1 teaspoon (2.5 g) cornstarch with the sauce ingredients in a separate small bowl.
Finish the prep before heating the pan. Slice the pepper and onion, cut the broccoli into small, fairly even florets, and separate the scallion whites from the greens. Combine the ginger, garlic, and optional pepper flakes in a small dish. Have the sauce and vegetables beside the stove: stir-frying moves quickly, and leaving the pan to chop an ingredient can cause the aromatics to scorch.
Sear the lamb in batches. Set a large wok or heavy skillet over high heat until very hot, then add about 1 teaspoon oil. Spread half the lamb in a single layer and sear, turning the pieces, for about 2–3 minutes; transfer them to a clean plate and repeat with another teaspoon of oil and the remaining lamb. Avoid crowding the pan, which traps steam and makes the meat pale rather than browned. Check several of the thickest strips with a thin-tip food thermometer: the USDA FSIS safe minimum for whole cuts of lamb is 145°F (63°C), followed by a 3-minute rest. Let the cooked lamb rest on the plate while you cook the vegetables.
Stir-fry the vegetables. Add the remaining oil to the hot pan. Add the broccoli and onion and stir-fry for 2 minutes, tossing often. Add the bell pepper and scallion whites and cook for another 1–2 minutes. The broccoli should be bright green and just tender, with a little bite; if the pan becomes dry before it softens, add 1 tablespoon (15 ml) water and toss for 30 seconds.
Add the aromatics, sauce, and lamb. Stir in the ginger, garlic, and pepper flakes and cook for about 20 seconds, just until fragrant. Give the sauce a quick stir to redistribute the cornstarch, pour it into the pan, and toss until it bubbles and thickens, about 30–60 seconds. Return the lamb and any juices to the pan, add the scallion greens, and toss for about 30 seconds to coat and warm everything through. Serve promptly while the vegetables are still crisp.

Tips

Slice evenly and against the grain. Strips of similar thickness cook at about the same rate. Look for the direction of the visible muscle fibers and cut across them, rather than along them. If the lamb is very soft and difficult to slice, chill it in the freezer for 15–20 minutes first; it should firm up but not freeze solid.
Use a hot, uncrowded pan. A wok is useful but not essential; a wide, heavy skillet works well. Cook the lamb in batches so it has contact with the hot surface. If the pan is small, divide the lamb into three batches rather than squeezing it all in at once.
Adjust the sauce thoughtfully. Light soy sauce is salty, so taste the finished sauce before adding extra salt. If using regular soy sauce instead, start with a little less and add more only if needed. Shaoxing wine is sold in many Asian grocery stores; dry sherry is a convenient substitute, though it gives the dish a slightly different, less distinctly Chinese-style aroma.
Make a useful oyster-sauce swap. For a vegetarian alternative, use vegetarian mushroom stir-fry sauce in the same amount. It keeps a similar savory quality, though the finished sauce may taste earthier. If you do not have either, add another teaspoon of soy sauce and a small pinch of sugar, knowing that the sauce will be less rounded.

Serving Suggestions

Serve the lamb stir fry straight from the pan over steamed jasmine rice, brown rice, or another plain grain that can soak up the sauce. For four servings, about 3 cups (570 g) uncooked rice, cooked according to its package directions, makes a generous base. If you prefer noodles, toss the stir fry with cooked wheat noodles or rice noodles just before serving; loosen the sauce with a spoonful of water if the noodles absorb it quickly.

For a lighter-feeling plate, serve it with additional steamed broccoli or blanched greens and keep the rice portion on the side. A simple cucumber salad dressed with rice vinegar makes a refreshing contrast to the warm, savory sauce. Set out extra sliced scallions or a little chili oil for people who want more heat, rather than increasing the spice in the whole pan.

Variations

Change the vegetables: Snow peas, sliced mushrooms, thin carrots, or shredded cabbage can replace some or all of the pepper and broccoli. Use about the same total volume, around 4 cups (350–450 g), so there is enough sauce to coat the panful. Add firm vegetables such as carrots first, and quick-cooking vegetables such as snow peas near the end. Watery vegetables can soften the sauce, so cook them over high heat and avoid overfilling the pan.

Make it hotter or more aromatic: Add a thinly sliced fresh red chili with the ginger and garlic, or increase the red pepper flakes to ½ teaspoon (1 g). For a more fragrant finish, add another ½ teaspoon (2.5 ml) sesame oil after turning off the heat; sesame oil is best used as a finishing flavor rather than as the main high-heat cooking oil.

Adjust for what is available: Lamb leg and loin are tender choices for a fast stir-fry. If you have a tougher cut, such as shoulder, slice it very thinly across the grain and expect it to need more careful cooking; it is not a direct one-for-one substitute if the pieces are thick. You can also use boneless lamb steaks, trimmed and sliced into strips. Keep the pieces evenly sized so you can check them reliably and avoid overcooking the thinner ones.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in a shallow, covered container. They keep for 3–4 days in the refrigerator. The vegetables will soften during storage, and the sauce may thicken as it chills; that is normal. For longer storage, freeze the cooled stir fry in a well-sealed container for up to 2 months for best quality. Thaw it overnight in the refrigerator rather than on the counter.

Reheat only the portion you plan to eat. Warm it in a skillet over medium heat with 1–2 tablespoons (15–30 ml) water, tossing until steaming hot, or microwave it in a covered, microwave-safe dish, stirring partway through. USDA guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer. Avoid reheating the same portion more than once, since repeated heating further softens the vegetables and makes the lamb less tender.

Frequently Asked Questions

What cut of lamb is best for stir fry?
Boneless leg or loin is a good choice because it is tender enough for quick cooking. Trim away thick pieces of surface fat, which can render into the pan and make the sauce greasy. Slice the meat across the grain and keep the strips evenly sized. Shoulder can work when sliced very thinly, but it is less forgiving if cut into thick pieces.

Can I prepare the ingredients ahead of time?
Yes. Slice the vegetables and mix the sauce up to a day ahead, storing them separately in covered containers in the refrigerator. You can also cut and season the lamb a few hours ahead and keep it chilled. For the best texture, cook the stir fry just before serving; fully cooked vegetables lose their crispness as they sit.

Why is my lamb stir fry tough?
Common causes are slicing with the grain, using a cut that needs longer cooking, crowding the pan, or leaving the lamb over the heat after it is done. Cut across the grain, sear in batches, and use a thermometer rather than guessing. The required 3-minute rest after lamb reaches its safe temperature also gives you time to cook the vegetables before returning the meat to the pan.

Can I make this without a wok?
Absolutely. Use the widest heavy skillet you have, preheat it thoroughly, and cook the lamb in small batches. A narrow pan holds less food in contact with the hot surface, so crowding is especially likely to make ingredients steam. If you are doubling the recipe, cook in separate rounds and combine everything with the sauce at the end.

Can I make this recipe gluten-free?
Use soy sauce labeled gluten-free, and check that the oyster sauce or vegetarian substitute and Shaoxing wine are also suitable for your needs. Some cooking wines and prepared sauces contain ingredients that may not be gluten-free. If you cannot find a suitable Shaoxing wine, dry sherry is an option only when its label meets your requirements; water can be used instead, though the sauce will have less depth.
