Panda Express String Bean Chicken Copycat Recipe: Crispy-Tender Bites With Silky Sauce

This Panda Express String Bean Chicken copycat recipe delivers the exact crispy-tender texture and silky sauce that made it a restaurant favorite. After years of perfecting restaurant-style stir-fries, I've cracked the code for replicating that signature combination of perfectly seared chicken and glossy sauce at home.

The secret lies in a precise marinade and high-heat stir-frying technique that creates that signature caramelized crust while keeping the chicken juicy inside.

The recipe begins with a simple yet effective marinade that tenderizes the chicken while building flavor—just soy sauce, brown sugar, and a touch of garlic.

Stir-frying in a hot wok or skillet ensures the chicken develops that signature crispy exterior, while the sauce, made with a blend of hoisin, oyster sauce, and a hint of ginger, clings beautifully to both the chicken and string beans.

The result is a dish that's restaurant-quality without requiring any special equipment.

By the time you plate this dish, you'll have perfectly balanced bites of crispy chicken, tender string beans, and that signature glossy sauce that ties everything together. The sauce is sweet, savory, and just slightly tangy—exactly how it should be.

This recipe serves four and comes together in under 30 minutes, making it perfect for busy weeknights when you crave takeout flavors without the wait.

Serve over steamed jasmine rice to complete the experience, just like at Panda Express. The combination of textures and flavors is what makes this dish so addictive—crispy chicken, tender vegetables, and that perfect sauce. Let's get started on recreating this classic at home.

Ingredients for panda express string bean chicken copycat

Fourteen ingredients, all easy to find—just check the Asian aisle for the secret sauce ingredients.

The chicken is the star, so pick boneless, skinless breasts—thighs work too but stay juicier. Pound them to even thickness so they cook perfectly. For the string beans, fresh is best but frozen works in a pinch. Trim the ends and cut into 2-inch pieces—no need to peel. The soy sauce and brown sugar marinade needs time to work its magic, so let the chicken soak for at least 20 minutes. I grab my soy sauce and oyster sauce from Kikkoman—their brands are consistent and reliable for copycat recipes.

No hoisin sauce? Substitute 1 tbsp soy sauce plus 1 tsp brown sugar—it won’t be identical but close enough. Fresh ginger is a must (powdered lacks punch), but if you’re out, 1 tsp ground ginger plus 1 tsp sugar gets you close. The sesame oil is for aroma—use sparingly, or the dish will taste bitter. For the crispy coating, cornstarch is key—flour won’t give the same texture. The green onions and sesame seeds are just for garnish, so don’t stress if you skip them.

This dish reheats beautifully—just toss the chicken and beans with a splash of water and warm through. Keeps for 3 days in the fridge, or freeze for 3 months if you’re prepping ahead. I always make extra rice—it’s the perfect side for leftovers. The sauce thickens as it cools, so thin with a splash of water if needed.

Step-by-step instructions for Panda Express string bean chicken copycat recipe

Here's how to nail the perfect crispy-tender chicken with that signature sweet-savory sauce.

Start by cutting the 1.5 lb boneless skinless chicken breast into 1-inch strips—keep them even in thickness so they cook uniformly. Place each strip between two sheets of plastic wrap and pound gently with a meat mallet until about ¼-inch thick. This ensures the chicken cooks through quickly without drying out.

While the chicken rests, trim the ends off the 1.5 lbs string beans and cut them into 2-inch pieces. Rinse them under cold water to remove any dirt, then drain well. The beans will absorb flavors better when they're clean and dry. I like to keep them whole for that classic Panda Express texture, but if you prefer softer beans, you can cut them into smaller pieces.

In a shallow bowl, mix the 2 tbsp cornstarch with 1 tbsp sesame oil and 1 tbsp neutral oil. This combination creates the perfect crispy coating while adding that signature sesame aroma. Toss the chicken strips in this mixture until they're fully coated—you should see an even, golden layer on each piece.

Let the coated chicken rest for 5 minutes while you heat 1 tbsp neutral oil in a large skillet over medium-high heat. The cornstarch needs time to adhere properly, and this resting period prevents the chicken from steaming instead of searing. When the oil is shimmering and hot, add the chicken in a single layer—don't overcrowd the pan or the temperature will drop.

Cook the chicken for 2-3 minutes per side until golden brown and crispy. You'll know it's ready when the edges are deeply browned and the chicken releases easily from the pan. If any pieces stick, gently lift them with a spatula and let them cook until they release naturally. Transfer the cooked chicken to a plate and tent loosely with foil to keep warm.

In the same skillet, add the 2-inch string bean pieces and cook for 3-4 minutes until they're bright green and slightly softened. You want them to stay crisp with just a hint of tenderness—overcooking will turn them mushy. Remove the beans and set them aside with the chicken.

Return the skillet to medium heat and add the 6 minced garlic cloves and 1 tbsp grated fresh ginger. Sauté for 30 seconds until fragrant—this builds the aromatic foundation of the sauce. Pour in the 0.5 cup extra-flight soy sauce, 0.25 cup light brown sugar, 0.25 cup hoisin sauce, and 0.25 cup oyster sauce. Stir well to combine, scraping up any browned bits from the bottom of the pan.

Bring the sauce to a gentle simmer and let it reduce for 3-4 minutes until it thickens slightly. You're aiming for a glossy, syrupy consistency that coats the back of a spoon. If it thickens too quickly, add 1-2 tablespoons of water to loosen it. The sauce should be sweet, savory, and just slightly sticky—this is what makes the dish so addictive.

Return the chicken and string beans to the skillet with the sauce. Toss everything together gently to coat the chicken and beans evenly. Cook for an additional 1-2 minutes just to heat through and let the flavors meld. The chicken should be tender with a crispy exterior, and the beans should be bright green with just a hint of bite.

Serve immediately over 1.5 cups cooked jasmine rice. Garnish with sliced green onion and toasted sesame seeds for that restaurant-quality finish. The contrast of crispy chicken, tender beans, and silky sauce over fluffy rice is what makes this dish so irresistible. Enjoy while it's hot—this copycat recipe delivers all the comfort of Panda Express right at home.

Dietary considerations for this panda express string bean chicken copycat

Gluten-Free Adaptation

This recipe is naturally gluten-free if you use certified gluten-free soy sauce and oyster sauce. I recommend Kikkoman Gluten-Free Tamari for soy sauce and Lee Kum Kee Gluten-Free Oyster Sauce to maintain authenticity.

The cornstarch coating can be replaced with gluten-free cornstarch (like Bob's Red Mill) or arrowroot powder for a crispy texture without gluten. Always check labels—some brands process products in gluten-containing facilities. 🌱

Low-Carb Option

For a lower-carb version, skip the rice and serve over cauliflower rice (about 2 cups cooked) or a bed of sautéed shirataki noodles. Reduce the brown sugar in the sauce to 1 tbsp and add 1 tsp erythritol or monk fruit sweetener for a sugar-free alternative.

The chicken and beans will still be the star, but with fewer carbs. This keeps the dish under 10g net carbs per serving.

Vegetarian Swap

Replace the chicken with extra-firm tofu pressed for 20 minutes to remove excess water. Cut into 1-inch cubes, then toss in the cornstarch mixture before cooking. For extra flavor, marinate the tofu in 2 tbsp soy sauce and 1 tbsp sesame oil for 15 minutes before coating.

The texture will be slightly different but still crispy and satisfying. 💫

Spicier Kick

Add ½ tsp red pepper flakes or 1 tsp sriracha to the sauce for heat lovers. For a smoky-spicy twist, stir in ½ tsp smoked paprika with the ginger. If you prefer fresh heat, toss in 1 tbsp chopped Thai basil or cilantro at the end for brightness.

The sauce will still be sweet and savory but with a fiery edge.

Allergen-Friendly Notes

For nut allergies, confirm all sauces (hoisin, oyster) are nut-free—some brands use peanuts in processing. Sesame allergies? Skip the sesame oil and seeds, or use toasted pumpkin seeds for garnish instead.

If shellfish is a concern, substitute oyster sauce with ½ cup coconut aminos plus 1 tsp fish sauce (or soy sauce for vegan versions). Always double-check labels for hidden allergens.
