This Panda Express String Bean Chicken copycat recipe delivers the same crispy-wok-fried texture and silky sauce you love from the restaurant—perfectly balanced between tender chicken and vibrant green beans.
After years of perfecting wok hei (breath of the wok) techniques, I've cracked the code for achieving that signature restaurant crunch at home without a specialized pan. The secret lies in high-heat searing and a precise sauce ratio that keeps it glossy yet not overly sweet.
What sets this recipe apart is the two-stage cooking process: first, the chicken gets marinated in a simple soy-ginger blend to develop flavor, then it's flash-fried until golden and crispy along the edges.
Meanwhile, the string beans stay bright and snappy, absorbing just enough sauce to enhance their natural sweetness. The sauce itself is a carefully balanced mix of hoisin, soy, and a touch of honey—sweet, savory, and slightly tangy—that coats every bite without overwhelming the dish.
By the time you plate it, you'll have restaurant-quality String Bean Chicken with crispy chicken pieces that shatter slightly when bitten and tender green beans glistening with sauce. The aroma alone—smoky from the wok, sweet from the sauce, fresh from the beans—will have everyone at the table asking for seconds.
This is the version that actually tastes like Panda Express, not just a close approximation.
Serve it with steamed white rice to soak up every last bit of sauce, or pair it with a simple cucumber salad for freshness. The leftovers reheat beautifully, making this an ideal meal-prep option for busy weeks. Let's bring that takeout favorite to your kitchen—crispy, saucy, and foolproof.
Ingredients for panda express string bean chicken copycat
Pantry staples plus a few specialty touches—this copycat delivers crispy-wok magic at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breast 🍗 | 1 ½ lb | Cut into 1-inch pieces |
| String Bean (Chinese Long Bean) 🌱 | 1 ½ lb | Trimmed, cut into 2-inch pieces |
| Hoisin Sauce 🍶 | ¼ cup | Store-bought or homemade |
| Light Soy Sauce 🥢 | ¼ cup | Kikkoman preferred |
| Honey 🍯 | 1 tbsp | Pure clover honey |
| Rice Vinegar 🍶 | 1 tbsp | White or seasoned |
| Garlic Cloves 🧄 | 4 cloves | Minced for marinade |
| Fresh Ginger 🌿 | 1 tbsp | Finely grated |
| Vegetable Oil 🫒 | ½ cup | High smoke point |
| Sesame Oil 🌰 | 1 tsp | Toasted for aroma |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Cornstarch 🌾 | 1 tbsp | For crispy coating |
| Green Onion 🧅 | 2 whole | Sliced for garnish |
| Sesame Seeds 🌰 | 1 tsp | Toasted for garnish |
The chicken is where the crunch happens. Boneless, skinless breasts work best—cut them into even 1-inch pieces so they cook uniformly. I grab mine from Costco when I'm making a big batch, but any grocery store has them. Look for plump, white meat with no yellowing. The string beans? Asian markets carry the long, flat Chinese variety, but regular green beans work in a pinch—just trim the ends and cut them into 2-inch pieces. Freshness matters here: beans should be crisp and bright green, not limp or discolored.
No hoisin sauce? Mix 2 tbsp soy sauce + 1 tbsp honey + 1 tsp sesame oil as a quick sub. The rice vinegar adds that signature tang—skip it if you're short, but the dish will taste flatter. For the marinade, fresh ginger is ideal, but ground ginger at half the amount works too. The cornstarch is non-negotiable for that crispy coating—arrowroot powder works too, but cornstarch is what Panda Express uses. Pro tip: Toss the chicken pieces with the cornstarch right before frying for maximum crunch.
This reheats like a dream—just toss with a splash of water and microwave for 1-2 minutes. Keeps for 4 days in the fridge, 3 months frozen. I always make extra because it disappears fast. Store the sauce separately if you're prepping ahead—just toss everything together when ready to eat. The sesame seeds and green onions are purely for garnish, so add them fresh right before serving.
Why You'll Love This Recipe
- No-Chop Nightmare: I swear, this recipe only needs three ingredients prepped—slice the chicken, trim the beans, and open a jar of hoisin. That’s it. (Yes, even on a Tuesday night when you’re still in your pajama pants.)
- Sweet-Savory Magic: The hoisin and honey balance out the soy sauce so perfectly—it’s got that sticky, slightly tangy glaze that clings to the chicken like it’s meant to be there. Crispy edges? Always. (My kids fight over the last piece.)
- Lunchbox Hero: Pack it cold for work or school—it stays fresh for days, and the flavors only get better. Honestly, I make a double batch every Sunday because it’s my go-to for lunches, potlucks, or when my book club shows up unannounced.
- Budget Win: Chicken breast and long beans are cheap, and hoisin stretches like crazy. I’ve fed four people for under $10, and there’s still leftovers for my dog. (Okay, fine, I don’t actually feed it to him—but it could happen.)
Step-by-step instructions for Panda Express string bean chicken copycat recipe
Here's how to recreate that iconic crispy-wok texture and silky sauce at home.
Prepare the Chicken and String Beans
Cut the 1.5 lb boneless, skinless chicken breast into 1-inch pieces, discarding any fat or connective tissue. Toss the chicken with 1 tbsp cornstarch in a large bowl until every piece is lightly but evenly coated. This creates the crispy exterior we're after.
Trim the 1.5 lb string bean (Chinese long bean) by snapping off the tough ends, then cut into 2-inch pieces. Set both the coated chicken and prepared string beans aside while you make the marinade. The cornstarch coating needs a few minutes to adhere properly before cooking.
Create the Flavorful Marinade
In a small bowl, whisk together the 0.25 cup hoisin sauce, 0.25 cup light soy sauce, 1 tbsp honey, 1 tbsp rice vinegar, 4 cloves minced garlic, and 1 tbsp finely grated fresh ginger. This marinade is what gives the dish that perfect balance of sweet, salty, and umami flavors.
Taste the marinade as you go—it should be tangy and slightly sweet. If it needs more depth, add a pinch of the 1 tsp salt or a few extra drops of rice vinegar. The marinade will infuse the chicken and string beans with incredible flavor during the quick cooking process.
Cook the Chicken to Crispy Perfection
Heat 0.5 cup vegetable oil in a large wok or skillet over medium-high heat until it shimmers but doesn't smoke. Add the chicken pieces in a single layer, being careful not to overcrowd the pan. Cook undisturbed for 3-4 minutes until golden brown on one side.
Flip the chicken and cook another 2-3 minutes until the cornstarch coating turns crispy and the internal temperature reaches 165°F. Remove the chicken to a plate and set aside. The chicken should be golden and crispy, not pale or rubbery. If it releases easily from the pan, it's ready.
Stir-Fry the String Beans and Combine
In the same wok, add another 1 tablespoon of vegetable oil if needed, then stir-fry the string beans for 3-4 minutes until bright green and just tender-crisp. They should still have a slight bite to them—overcooking will make them mushy.
Return the cooked chicken to the wok along with the prepared marinade. Stir everything together and cook for 1-2 minutes until the sauce begins to thicken slightly and coats the chicken and string beans evenly. The mixture should look glossy and well-combined.
Finish and Garnish
Remove the wok from heat and stir in 1 tsp sesame oil. This adds a nutty aroma that perfectly complements the other flavors. Taste and adjust seasoning if needed—you might want to add a splash of light soy sauce or a touch more honey to match your preference.
Garnish with sliced green onion and toasted sesame seeds before serving. The sesame seeds add a delightful crunch and visual appeal. Serve immediately while the chicken is still crispy and the sauce is silky. This dish tastes best straight from the wok!
Pro Tips For Making Panda Express String Bean Chicken Copycat
- CUT CHICKEN SMALL: The original recipe uses tiny, uniform pieces—about ½-inch cubes—so they cook evenly and soak up the sauce. I used to eyeball it and ended up with uneven doneness, so grab a knife and go for consistency. (Yes, it’s tedious, but it’s the thing that matters most.)
- BLANCH BEANS FIRST: String beans need a quick 30-second blanch in boiling water before stir-frying—this softens them just enough to avoid crunch while keeping their shape. Skip this, and you’ll either have rock-hard beans or mushy ones. (I learned this the hard way after a batch turned into a sad, limp pile.)
- SAUCE IN STAGES: Don’t dump all the hoisin, soy, and honey at once—start with half the sauce and let it reduce slightly before adding the rest. This keeps the chicken from steaming instead of searing, and the sauce gets that glossy, sticky texture that makes the dish sing. (Your future self will thank you.)
- REST CHICKEN BEFORE SAUCE: After searing the chicken, let it sit off the heat for 5 minutes under foil. This keeps it juicy when the sauce gets added later. I used to rush this step and ended up with dry, tough pieces—now I just wait, even when I’m impatient. (It’s worth it.)
Pro cooking tips for perfect results
Wok Hei Mastery
That signature restaurant "breath of the wok" flavor comes from high, dry heat and quick cooking. Use a 14-inch cast iron wok (like Lodge) for best results, but a heavy stainless steel skillet works too.
Heat it until it's smoking hot—you should see steam when you add the chicken. I crank my burner to medium-high heat and let it preheat for 3-4 minutes before adding oil. This ensures proper searing and prevents soggy chicken. 🔥
Chicken Prep Secrets
Cutting the chicken into even 1-inch pieces is critical for uniform cooking. I use a sharp chef's knife and slice against the grain for maximum tenderness. The cornstarch coating needs to be light but even—toss the pieces gently in a bowl until they're just dusted, not glued together.
Overcoating makes them gummy instead of crispy. Pat them dry first with paper towels to remove excess moisture.
Sauce Timing Tricks
The marinade should coat the chicken and beans right before serving to maintain crispiness. I make the sauce first, then set it aside while cooking. When combining, stir just until the sauce clings—overmixing makes the chicken mushy.
Add the sesame oil off the heat to preserve its delicate aroma. For extra gloss, I drizzle ½ tsp water into the sauce before combining. 💫
String Bean Perfection
Chinese long beans (string beans) should be bright green and crisp-tender—they cook faster than regular green beans. Stir-fry them for exactly 3-4 minutes over high heat. If using regular green beans, cut them into 1.5-inch pieces and cook for 2 minutes.
Undercooked beans stay crunchy but bland; overcooked ones turn limp. Taste-test one piece before combining with the chicken.
Reheating Like a Pro
Leftovers lose crispiness fast, so reheat carefully. Toss the chicken and beans with 1 tsp vegetable oil and 1 tsp water, then microwave on high for 45 seconds. For stovetop, use a nonstick skillet over medium heat for 2-3 minutes until heated through.
The cornstarch coating will crisp up again—just add a splash of water to the sauce if it thickens too much. ⏰
Equipment Upgrades
My must-have tools for this recipe: a 14-inch wok, tongs (not a spoon—you'll crush the chicken), and a meat thermometer to check 165°F internal temp. A ladle helps toss everything together without overcrowding.
For home cooks without a wok, a heavy-bottomed stainless steel skillet works—just make sure it's well-seasoned. I also keep a small bowl of ice water nearby to plunge overcooked beans if needed. 🌡️

Frequently asked questions
Can I substitute regular green beans for Chinese long beans?
Yes, but you'll need to adjust the cooking time. Regular green beans cook faster—cut them into 1.5-inch pieces and stir-fry for only 2 minutes instead of 3-4 minutes. They won't be as long and flat as Chinese long beans, but the flavor will still be delicious. For extra authenticity, look for "yard-long beans" at specialty markets.
How do I keep the chicken extra crispy?
The key is the cornstarch coating and high heat. Pat the chicken pieces very dry before tossing with cornstarch, and cook them in a smoking-hot wok without overcrowding. For even more crunch, broil the cooked chicken for 1-2 minutes before combining with the sauce. Just watch closely to avoid burning!
Can I make this recipe without a wok?
Use a heavy stainless steel skillet (like All-Clad) or cast iron pan. The important part is getting the pan smoking hot before adding oil. A nonstick pan works too, but you won't get the same wok hei flavor. Just make sure to preheat it for 3-4 minutes on medium-high heat first.
What's the best way to store leftovers?
Store the chicken and beans separately from the sauce in airtight containers to keep everything crispy. The sauce will stay fresh for 5 days in the fridge, while the chicken and beans keep their texture for 3 days. For longer storage, freeze the components separately for up to 3 months. Reheat gently with a splash of water to restore crispiness.
Why is my sauce too sweet or not sweet enough?
The sauce balance depends on your taste. For more sweetness, add ½ tsp honey at a time. For less sweetness, reduce the honey by ½ tsp and add ½ tsp rice vinegar instead. The ideal ratio should be slightly sweet with a tangy finish. Taste as you go—you can always adjust while cooking, but avoid adding too much soy sauce at once.
