Ingredients for beef chop suey recipe with bean sprouts
Here's what you'll need to create this wok-seared beef chop suey with vibrant bean sprouts and umami-packed bites.
| Ingredient | Amount | Notes |
|---|---|---|
| Flank Steak 🥩 | 1 ½ lb | Thinly sliced against grain |
| Bean Sprouts 🌱 | 4 cups | Fresh, rinsed and drained |
| Red Bell Pepper 🌶️ | 1 whole | Thinly sliced |
| Green Bell Pepper 🌶️ | 1 whole | Thinly sliced |
| Green Onions 🧅 | 6 whole | Thinly sliced, white and green parts |
| Garlic Cloves 🧄 | 4 cloves | Minced |
| Fresh Ginger 🌿 | 1 tbsp | Grated |
| Soy Sauce 🍶 | ⅓ cup | Low-sodium preferred |
| Oyster Sauce 🍶 | 2 tbsp | High-quality brand |
| Sesame Oil 🫒 | 1 tbsp | Toasted, for finishing |
| Vegetable Oil 🫒 | 2 tbsp | High smoke point |
| Brown Sugar 🍯 | 1 tbsp | Light or dark |

| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
The flank steak is key here—it's lean and tender when sliced thinly against the grain. Costco or Whole Foods usually have it pre-sliced, but if you're cutting it yourself, freeze it for 30 minutes first to make slicing easier. Look for bright red, marbled meat—avoid anything grayish. The bean sprouts should be vibrant green and crisp; Trader Joe's has the freshest, but any grocery store's produce section works. Bell peppers should be firm with glossy skins—no wrinkly ones. Fresh ginger and garlic? Penzeys Spices sells pre-peeled garlic and ginger if you're short on time, but fresh is always better.
No flank steak? Sirloin or ribeye work too, but slice extra thin. Swap bell peppers for snow peas or bok choy if you're feeling adventurous. The soy sauce can be tamari for gluten-free, and if you're missing oyster sauce, hoisin sauce plus a splash of fish sauce gets you close. Sesame oil is non-negotiable for that wok hei flavor—Kadoya is my go-to brand. Brown sugar can be white sugar or honey in a pinch, but brown adds depth. The cornstarch? Arrowroot powder works too if you're avoiding gluten.
Prep everything before cooking—this is a fast dish! Store bean sprouts in a damp paper towel in the fridge for up to 5 days. Fresh ginger keeps for 2 weeks in the fridge, but freeze it if you won't use it soon. The sauce can be made ahead and reheated—it actually tastes better the next day as flavors meld. Leftovers? 3-4 days in the fridge, or freeze for 3 months. I always make extra rice to go with it—this dish is even better the second day.

Step-by-step instructions for beef chop suey with bean sprouts
Here's how to create a restaurant-quality stir-fry with perfectly seared beef and crisp-tender vegetables.
Prep All Ingredients Efficiently
Start by slicing the 1.5 lb flank steak thinly against the grain into ¼-inch thick strips. This ensures tender bites that cook quickly in the wok. While the meat rests, thinly slice the red bell pepper, green bell pepper, and green onions—you'll want even strips about ¼-inch wide for quick cooking.
Mince the 4 cloves garlic cloves and grate the 1 tbsp fresh ginger. Rinse and drain the 4 cups bean sprouts thoroughly to remove any dirt. Keep all prepped ingredients in separate bowls so they're ready to go as you cook. The key here is speed—having everything prepped prevents that dreaded "waiting while veggies sit" moment that ruins stir-fries.
Create the Flavor Base
Heat a wok or large skillet over high heat until it's smoking hot. Add 2 tbsp vegetable oil and swirl to coat. Once the oil shimmers, add the sliced flank steak in a single layer and let it sear undisturbed for 1-2 minutes until the edges turn golden brown. This initial sear locks in juices and builds deep flavor.
Push the beef to one side of the wok and add 2 tbsp vegetable oil to the empty space. Toss in the red bell pepper, green bell pepper, and green onions, stirring constantly for 2-3 minutes until they soften but still retain a slight crunch. Add the 4 cloves minced garlic and 1 tbsp grated ginger, cooking for another 30 seconds until fragrant. Here's where the magic happens—don't rush this step or you'll miss the aromatic punch.
Build the Sauce and Combine
Lower the heat to medium-high and add 0.33 cup soy sauce, 2 tbsp oyster sauce, 1 tbsp brown sugar, and 1 tbsp cornstarch. Stir vigorously for 1-2 minutes until the sauce begins to thicken slightly. The cornstarch helps create that glossy, slightly sticky texture that clings perfectly to the beef and vegetables.
Add the 4 cups bean sprouts and toss everything together for another 2 minutes until the bean sprouts just wilt slightly but still hold their shape. You want them to stay crisp—overcooking turns them mushy. Taste and adjust seasoning with 1 tsp salt and 0.5 tsp black pepper if needed. The sauce should be savory-sweet with just the right balance of umami.
Finish with Sesame Oil for Depth
Transfer the beef chop suey to serving plates and let it rest for 2 minutes. This brief rest allows the flavors to meld together. Drizzle each serving generously with 1 tbsp sesame oil and toss lightly to distribute. The sesame oil adds that final nutty aroma and rich depth that makes this dish truly special.
Serve immediately while everything is hot and the bean sprouts still have that satisfying crunch. The beef should be tender but still hold its shape, and the vegetables should be vibrant with just a hint of char. This dish tastes even better the second day, so make extra if you can—it's that good.
Pro Tips For Making Beef Chop Suey Recipe With Bean Sprouts
- Slice Against the Grain: Flank steak fights you if you cut it wrong—slice it thinly across the grain before cooking, not after. I used to ignore this and ended up with chewy strips that ruined the whole dish. Trust me, the effort makes the difference.
- Blanch the Peppers: Toss your red and green bell peppers into boiling water for 30 seconds first—shock them in ice water, then drain. This softens them just enough to cook through without turning to mush, especially when stir-frying with the beef.
- Don’t Overcrowd the Pan: If you pile everything in at once, your chop suey will steam instead of sear. Cook the beef first in batches, then push it to the sides and add the veggies in stages. Crowding turns a quick stir-fry into a sad, soggy mess.
- Use Day-Old Bean Sprouts: Fresh bean sprouts release too much water when cooked, drowning the dish. Rinse them well, pat dry, and use them within a day or two of buying. If they’re wilting, skip them—your chop suey will thank you.
Regional styles of beef chop suey recipe with bean sprouts
American Home-Style
This version keeps the classic elements but simplifies for home cooks using standard kitchen tools. I often make this when hosting friends who aren't familiar with wok cooking. Use a large cast-iron skillet instead of a wok—it retains heat beautifully and creates that satisfying sear.
The sauce stays the same, but I reduce the sesame oil to ½ tbsp since cast iron already adds depth. Serve with steamed jasmine rice and a side of quick-pickled cucumbers to balance the richness.
The key is keeping the heat high and the prep organized—this is how I make it feel approachable for weeknight dinners. 🥢
Hong Kong Street Food
For a more authentic take, I draw inspiration from Hong Kong's bustling street food culture. Here, the beef is often pre-marinated in a mix of 1 tbsp soy sauce, 1 tbsp Shaoxing wine, and ½ tsp white pepper for 30 minutes before cooking.
The sauce gets a boost with 1 tsp chili paste and ½ tsp five-spice powder, adding complexity. Serve with crispy fried shallots on top and a side of steamed egg rolls for that true street food experience.
The bean sprouts are added last to keep them crisp, just like you'd find at a busy market stall. 🌆
Modern Fusion Twist
This version blends chop suey with contemporary flavors by adding 1 cup sliced shiitake mushrooms and ½ cup baby corn to the stir-fry. The sauce gets a modern update with 1 tbsp fish sauce and 1 tsp rice vinegar for brightness.
I finish with toasted coconut flakes and lime wedges for serving—it's a fusion of Asian and tropical flavors that works beautifully for brunch or lunch. The mushrooms add an earthy depth while the baby corn brings a fun texture contrast. Perfect for foodies who love playful flavor combinations. 🌱
Korean-Inspired Bibimbap Style
For a Korean-inspired adaptation, I swap the soy sauce for 1 tbsp gochujang (Korean chili paste) and add 1 tsp toasted sesame seeds to the sauce mix. The beef gets a quick toss with 1 tbsp gochugaru (Korean chili flakes) before stir-frying.
Serve over steamed rice and top with fried egg and kimchi for a full bibimbap experience. The bean sprouts stay crisp, but the spicy-sweet sauce ties everything together beautifully. This version is perfect for those who love bold, spicy flavors with a comforting finish. 🌶️
Vegetarian Adaptation
To make this vegetarian, replace the beef with 1.5 lbs extra-firm tofu pressed and sliced into strips, then pan-fried until crispy. The sauce remains the same, but I add 1 tbsp miso paste for extra umami depth.
Toss in ½ cup chopped water chestnuts for texture and 1 cup sliced bok choy for extra greens. Garnish with toasted sesame seeds and scallions for a vibrant, protein-packed dish that still delivers that satisfying chop suey experience. 🌿

Frequently asked questions
Can I use ground beef instead of flank steak?
Ground beef works wonderfully for a quicker, more approachable version. Use 1 lb lean ground beef (90/10 ratio) and break it into 1-inch pieces before cooking. Brown it thoroughly first to develop flavor, then proceed with the recipe as written. The texture will be slightly different but still delicious—just expect a more tender result than with flank steak.
How do I keep the bean sprouts extra crisp?
The secret is timing and technique! Add the bean sprouts only in the last 1-2 minutes of cooking when everything else is nearly done. Use a well-heated wok or skillet and stir constantly to prevent steaming. For extra crunch, finish by tossing with 1 tsp cold water and ½ tsp sesame oil right before serving. This creates a light, refreshing contrast to the warm beef.
What's the best way to store leftovers?
Store in an airtight container in the fridge for up to 4 days. The flavors actually improve overnight as the sauce melds! Reheat gently in a skillet over medium heat with 1 tsp water to prevent drying. For freezing, portion into single servings and freeze for up to 3 months. Thaw overnight in the fridge—never microwave directly from frozen.
Can I make this gluten-free?
Yes! Swap regular soy sauce for tamari or coconut aminos (use the same amount). Check your oyster sauce—some brands are gluten-free, but if not, replace with ½ cup gluten-free hoisin sauce plus 1 tsp fish sauce. Use cornstarch for thickening, or substitute with arrowroot powder. The flavor will still be rich and umami-packed, just adapted for dietary needs.
Why does my sauce get too thick?
This usually happens from overcooking the cornstarch or using too much. For next time, mix the cornstarch with 2 tbsp cold water first to create a slurry, then add it gradually while stirring constantly. Keep heat at medium-high—too low heat causes uneven thickening. If it gets too thick, add 1 tsp water or broth to loosen. The sauce should coat the back of a spoon but still be pourable.
