Chinese Bean Sprout Stir-Fry with Garlic and Scallions

This Chinese-style mung bean sprout stir-fry cooks crisp sprouts quickly with garlic, scallions, ginger, and a light soy-and-vinegar sauce. It is a savory, flexible side dish; home and regional versions vary, and this simple version keeps the sprouts at the center.

Ingredients

1 lb (450 g) fresh mung bean sprouts
1 tbsp (15 ml) neutral oil, such as canola or peanut oil
3 medium garlic cloves (about 9 g), finely minced
1 tsp (2 g) finely grated fresh ginger
3 scallions (about 30 g), thinly sliced; keep the white and green parts separate
1 tbsp (15 ml) light soy sauce
1 tbsp (15 ml) Shaoxing cooking wine
1 tsp (5 ml) Chinese black vinegar, such as Chinkiang vinegar; use rice vinegar for a lighter, less malty flavor if needed
½ tsp (2 g) sugar
¼ tsp (0.5 g) ground white pepper
1 tsp (5 ml) toasted sesame oil
⅛ tsp (0.75 g) fine salt, optional, to taste

Instructions

Rinse and dry the sprouts. Pick through the mung bean sprouts and discard any that are slimy, bruised, or unpleasant-smelling. Rinse them under cool running water, then drain very thoroughly and spread on a clean towel or spin gently in a salad spinner. Wet sprouts tend to steam and water down the seasoning instead of stir-frying. Trim long root tails only if you prefer; it is not necessary for the recipe.
Prepare the aromatics and sauce. Mince the garlic, grate the ginger, and slice the scallions, separating their white and green parts. In a small bowl, stir together the soy sauce, Shaoxing wine, black vinegar, sugar, and white pepper until the sugar dissolves. Have the bowl and sprouts beside the stove before you begin: once the pan is hot, the cooking moves quickly.
Heat the pan. Set a large wok or a 12-inch (30 cm) skillet over high heat for about 1 minute. Add the neutral oil and swirl to coat the bottom. The oil should look fluid and shimmer, but it should not smoke heavily. If your pan is smaller than 12 inches, plan to stir-fry the sprouts in two batches so they can make good contact with the hot surface.
Cook the aromatics. Add the garlic, ginger, and scallion whites. Stir constantly for about 30 seconds, just until fragrant. Keep them moving so the garlic does not scorch; burnt garlic can make the whole dish bitter. If the pan seems dry, move straight to the sprouts rather than adding extra oil.
Stir-fry the sprouts. Add the well-drained sprouts and toss continuously for about 2 minutes. Use a spatula to lift and turn them from the bottom of the wok. They will soften slightly and shrink, but should still have a lively crunch. Avoid pressing them into a heap or covering the pan, since trapped steam makes them limp.
Season and finish. Pour the sauce around the hot sides of the pan, then toss for 1 minute so it coats the sprouts. Continue cooking for another minute, tossing, until the sprouts are steaming hot throughout and crisp-tender. Turn off the heat, add the scallion greens and sesame oil, and toss for about 30 seconds. Taste before adding the optional salt, since soy sauce is already salty. Serve right away.

Tips

Drying matters. Water clinging to the sprouts lowers the pan temperature and thins the sauce. After rinsing, drain well and blot them dry if needed. If you are washing sprouts ahead, keep them refrigerated and dry them again just before cooking.
Use a wide, hot pan. A wok is useful but not essential; a broad skillet works well. Crowding is the more common problem. If the sprouts mound above the pan or stop sizzling when added, cook in batches and return everything to the pan for the sauce.
Adjust the seasoning thoughtfully. Light soy sauce gives salt and savory flavor without darkening the sprouts too much. If you only have regular soy sauce, use 2 teaspoons (10 ml) and add a teaspoon of water. Shaoxing wine can be replaced with dry sherry; omitting it and using 1 tablespoon (15 ml) water gives a simpler flavor. Rice vinegar works in place of black vinegar, though it is brighter and less complex.
Cook sprouts rather than serving them raw. Fresh sprouts are perishable, and rinsing does not remove every possible food-safety risk. Keep them refrigerated until cooking, discard sprouts that seem spoiled, and cook them until steaming hot throughout. People at higher risk from foodborne illness should avoid raw or lightly cooked sprouts.

Serving Suggestions

Serve the stir-fry as soon as it leaves the pan, while the sprouts are still crisp. It pairs naturally with steamed rice, congee, or plain noodles, and its savory, lightly tangy sauce works well alongside dishes with a richer or more deeply seasoned flavor. For a simple meal, serve it with rice and a bowl of clear vegetable soup. It can also be placed on the table as one of several shared dishes, where its fresh crunch provides contrast to braised vegetables or roasted tofu.

If serving rice, start it before you prep the sprouts so both are ready together. Keep the bean sprouts in a serving bowl rather than leaving them in the hot wok; residual heat continues to soften them. A final sprinkle of scallion greens is enough garnish, though a few sesame seeds can be added if desired. The recipe is seasoned as a side, so taste it with the rest of the meal before adding more salt or soy sauce.

Variations

Make it spicy: Add ½ teaspoon (2.5 ml) chili crisp or chili oil at the table, or stir ¼ teaspoon (about 0.5 g) red pepper flakes into the garlic and ginger. Adding the heat at serving lets each person choose a level and keeps the base dish balanced.

Add tofu: Use 8 oz (225 g) firm tofu, patted dry and cut into small cubes. Brown it in the hot oil first, remove it to a plate, then cook the aromatics and sprouts as directed. Return the tofu when you add the sauce. This adds substance, so the sprouts may need a little more tossing to heat through.

Use soybean sprouts: Soybean sprouts are thicker and have a nuttier taste than mung bean sprouts. They can take an extra 1–2 minutes to become hot and tender-crisp, so judge by texture rather than relying only on the clock. Very thick stems may remain firmer, which is normal.

Add another vegetable: A small carrot cut into fine matchsticks or 1 cup (70 g) thinly sliced napa cabbage can go into the pan just before the sprouts. Cook the carrot for about 1 minute first; cabbage releases more water, so use a wide pan and keep the heat high. Avoid adding a large quantity of vegetables, which can crowd the pan and soften the sprouts.

Storage and Reheating

This stir-fry is best freshly cooked because sprouts lose their crunch as they cool and sit. If you have leftovers, transfer them to a shallow airtight container and refrigerate within 2 hours. Keep them refrigerated for 3–4 days, but expect a softer texture after storage. Do not leave the cooked dish at room temperature for an extended period.

Reheat only the amount you plan to eat, either in a hot skillet for a few minutes or in the microwave in short intervals, stirring between intervals. Reheat leftovers to 165°F (74°C), as measured with a food thermometer. The sprouts will be softer than when first cooked, so avoid repeatedly reheating the full batch. Freezing is not recommended for the best texture: thawed sprouts tend to become watery and limp.

Frequently Asked Questions

Can I make Chinese bean sprout stir-fry ahead?

It is better to prepare the sauce and chop the aromatics ahead, then cook the sprouts just before serving. If you cook the full dish in advance, it will still be usable, but the sprouts soften as they stand. Keep prepped ingredients covered and refrigerated, and do not leave washed sprouts sitting wet in a bowl.

Do I need to remove the roots from bean sprouts?

No. Root trimming is optional and mostly affects appearance and texture at the ends. For a quick weeknight side, sort the sprouts, rinse them, and leave the roots on. If the sprouts have unusually long, dark, or damaged tails, you can pinch those off while checking the batch.

Why did my sprouts turn watery?

The pan may have been too cool, the sprouts may have gone in wet, or too many may have crowded the pan. Dry them well, preheat the wok or skillet, and cook in batches if needed. Add the sauce near the end and keep tossing over high heat so it clings instead of collecting at the bottom.

Can I make this recipe gluten-free?

Yes, use a gluten-free tamari in place of soy sauce and check the labels on the Shaoxing wine and vinegar. If you cannot confirm the wine is gluten-free, omit it and add 1 tablespoon (15 ml) water instead. The flavor will be a little less rounded, but the garlic, ginger, and vinegar still season the sprouts well.

Can I use canned bean sprouts?

Fresh sprouts give this dish its characteristic crisp texture, while canned sprouts are already softened and usually packed in liquid. They can be used in a pinch: drain and rinse them thoroughly, dry as well as possible, and shorten the stir-fry so they do not fall apart. The finished dish will be softer and less fresh-tasting.

Can I eat mung bean sprouts raw?

Raw sprouts are sometimes used in dishes, but they can carry foodborne bacteria, and washing alone cannot eliminate that risk. This recipe is intended to cook the sprouts until steaming hot. For children, older adults, pregnant people, and anyone with a weakened immune system, cooked sprouts are the safer choice.
