String Bean Chicken Breast: Allergens at a Glance
The honest verdict
String Bean Chicken Breast · Panda Express
String Bean Chicken Breast is a Panda Express stir-fry dish featuring chicken breast pieces and string beans in a savory soy-based sauce. The primary allergens are soy (from soy sauce) and wheat (from soy sauce and possible thickeners). Milk, egg, peanut, tree nut, fish, shellfish, and sesame are not standard ingredients in the dish itself. The dish is not breaded or deep-fried — it is wok-tossed, which reduces the cross-contact risk from shared fryers but introduces wok cross-contact from other stir-fry dishes cooked on the same surface. This is a different allergen profile from Panda Express's Orange Chicken (breaded + fried) or Beijing Beef (breaded + fried + soy). Always confirm with your specific Panda Express location before ordering.

Key facts
String Bean Chicken Breast is a wok-tossed stir-fry, not breaded or deep-fried, reducing the shared-fryer cross-contact risk found in Orange Chicken or Beijing Beef.
Soy sauce, the base of this dish, typically contains both soy and wheat — making it a dual-allergen source for those with soy or wheat allergies.
FDA — Food Allergen Labeling and Consumer Protection Act (FALCPA)
Shared wok surfaces at Panda Express create cross-contact risk between dishes — particularly from Kung Pao Chicken (peanuts) and Beijing Beef (wheat).
Every major allergen, one clear grid
Each of the nine major allergens marked for String Bean Chicken Breast at Panda Express — Contains, May contain (cross-contact or varies), or Free. Anything we couldn't confirm defaults to "may contain," because a shared kitchen can't be ruled out without the restaurant's official menu.
| Allergen and notes | Status |
|---|---|
Milk Milk is not a listed ingredient in the standard String Bean Chicken Breast recipe. The sauce is soy-based, not cream-based. No cheese or dairy components are typical. | Free |
Egg Egg is not a standard ingredient in this dish. Some stir-fry sauces may use egg as a thickener, but this is not typical for Panda Express's String Bean Chicken Breast recipe. | Free |
Wheat / Gluten Soy sauce, the base of the stir-fry sauce, is traditionally made from wheat and soybeans. Some chains use tamari or wheat-reduced soy sauce — Panda Express's standard soy sauce contains wheat. Confirm the specific soy sauce type with the restaurant if you have celiac disease or wheat allergy. | Contains |
Soy Soy sauce is the primary seasoning base for this dish, making soy a definite allergen. The dish also uses soybean oil for cooking. For those with soy allergy, this dish is not a safe option unless the restaurant can confirm a soy-free preparation. | Contains |
Peanut Peanuts are not an ingredient in String Bean Chicken Breast. Unlike Kung Pao Chicken (which contains peanuts), this dish uses string beans and chicken only. Cross-contact from shared woks is possible if the same wok is used for peanut-containing dishes. | Free |
Tree Nut Tree nuts are not a listed ingredient in this dish. No cashews, almonds, or other tree nuts are used in the standard recipe. | Free |
Fish Fish is not an ingredient in String Bean Chicken Breast. The dish uses chicken breast and vegetables, not fish or fish sauce. Some Asian sauces use fish sauce as a base — this dish uses soy sauce instead. | Free |
Shellfish Shellfish is not an ingredient in this dish. No shrimp, crab, or other shellfish components are used in the standard recipe. | Free |
Sesame Sesame oil is not a standard ingredient in String Bean Chicken Breast at Panda Express. Some locations may use sesame oil in their wok cooking — confirm with your specific location if sesame allergy is a concern. | Free |
“May contain” means cross-contact is possible or the answer varies by location — not that the allergen is a listed ingredient. For a severe allergy, treat “may contain” the same as “contains” until the restaurant confirms otherwise.
Small changes that remove an allergen
Simple modifications that can take an allergen off your string bean chicken breast. Always name your allergy when you order and ask staff to confirm — a modification only helps if the kitchen prepares it separately.
Request preparation in a wok not used for peanut-containing dishes (Kung Pao Chicken)
Ask if the restaurant can use a wheat-free soy sauce (tamari) for the sauce base
Request no added soy sauce and a simple oil + vegetable stir-fry instead
Verify the cooking oil used — some locations may use peanut oil for wok cooking
A modification lowers exposure but doesn't erase cross-contact from shared fryers, grills, or prep surfaces. For a severe allergy, confirm the prep with a manager before you eat.

Cross-contact & severe allergies
A “free of” mark on the grid above means the allergen isn't an ingredient — it doesn't mean the item was made in an allergen-free kitchen. Two things matter most:
Shared fryers & equipment
String Bean Chicken Breast is stir-fried in a wok, and Panda Express cooks multiple dishes on the same wok line throughout the day. Cross-contact from other dishes — particularly Kung Pao Chicken (peanuts), Beijing Beef (wheat breading), or Orange Chicken (wheat breading + shared fryer) — is possible. The wok surface and utensils are shared unless a dedicated wok is requested. Cross-contact risk is lower than deep-fried items but still present for severe allergies.
If your allergy is severe
For anaphylactic allergy to soy, wheat, or peanut, confirm wok preparation practices with the specific Panda Express location before ordering. String Bean Chicken Breast is not guaranteed safe for any of these allergens without restaurant-level confirmation. Carry your epinephrine auto-injector. If you cannot confirm preparation details, consider a simpler steamed rice or vegetable side instead.
This guidance is general and can't account for how any single location prepares your food. The restaurant's staff and official allergen menu are the final word — when in doubt, ask, or choose something else.
Avoidance is not the only option for wheat allergy
There is no FDA-approved immunotherapy for wheat allergy, and options are narrower here than for peanut or milk. Xolair is approved to reduce the severity of reactions to accidental exposure across IgE-mediated food allergies. A wheat allergy is also a different condition from coeliac disease, which immunotherapy does not treat.
Beyond that, oral immunotherapy in a specialist clinic raises reaction thresholds the most of any current approach, and sublingual immunotherapy raises them less but causes markedly fewer reactions and is easier to keep up over years. Neither makes any particular dish safe to eat, and an epinephrine auto-injector stays with you throughout.
A history of anaphylaxis, or severe or poorly controlled asthma alongside the food allergy, means this belongs with an in-person allergist rather than any remote service.
Frequently Asked Questions
Yes. Soy sauce is the primary seasoning in this dish, making soy a definite allergen. The dish also uses soybean oil for cooking. For those with soy allergy, this dish is not a safe option unless the restaurant can confirm a soy-free preparation using an alternative oil and no soy sauce.
No, not in its standard preparation. The soy sauce used at Panda Express contains wheat. Some locations may offer a gluten-free soy sauce alternative (tamari) upon request, but this is not standard. The dish itself has no breading, which is a difference from Orange Chicken or Beijing Beef, but the wheat in the sauce remains unless substituted.
No, peanuts are not an ingredient in String Bean Chicken Breast. This is a key difference from Kung Pao Chicken, which contains peanuts. However, cross-contact from shared woks is possible if the same wok is used for peanut-containing dishes without proper cleaning between orders.
Yes, based on standard ingredients. Milk and egg are not listed in the recipe. The sauce is soy-based, not cream-based, and no egg is used as a thickener. As always, confirm with your specific location, as recipes can vary by region or change over time.
String Bean Chicken Breast is one of the simpler allergen profiles at Panda Express. It contains soy and wheat from the sauce but lacks the breading (wheat) found in Orange Chicken and Beijing Beef, and lacks the peanuts found in Kung Pao Chicken. It is also not deep-fried, reducing the shared-fryer cross-contact risk. The main concern is wok cross-contact from other dishes cooked on the same surface.
