What Oil Does Panda Express Use?
The short answer: soybean oil. Panda Express uses highly refined soybean oil for all wok cooking. Here is what that means in practice — for peanut allergies, soy allergies, and the one item that does contain actual peanuts.
Quick Answer
Panda Express uses soybean oil — not peanut oil, canola, or a vegetable blend. The oil is highly refined, which means soy proteins are removed and it is generally safe for soy-allergic diners. The only item that contains peanuts as an actual ingredient is Kung Pao Chicken.
The Confirmed Cooking Oil
Panda Express cooking oil: Soybean oil
Soybean oil is used consistently across Panda Express locations for wok cooking. It has a high smoke point (approximately 450°F / 232°C), which makes it well-suited for the high-heat stir-frying used at Panda Express. It is also significantly less expensive than peanut oil at the volume a large chain operates.
Why People Assume Peanut Oil
The belief that Panda Express uses peanut oil is widespread and comes from two sources:
The Chinese-American cooking association
Traditional Chinese stir-fry recipes frequently call for peanut oil because of its high smoke point and neutral-to-light flavor. Many diners assume that a Chinese-American chain uses the same oil. Panda Express standardized on soybean oil instead — a common choice for food-service operations managing cost and consistency at scale.
Kung Pao Chicken contains peanuts
Kung Pao Chicken lists peanuts as an ingredient. Customers who ask about peanuts and hear "yes, Kung Pao Chicken contains peanuts" sometimes extrapolate this to mean the cooking oil is peanut-based. The peanuts in Kung Pao Chicken are whole peanuts added as a component of the dish — entirely separate from the cooking oil used in the wok.
Refined Soybean Oil and Soy Allergy
Knowing the cooking oil is soybean oil raises an important question for soy-allergic diners.
Why refined soybean oil is generally safe for soy allergies
Soy allergic reactions are triggered by soy proteins. The refining process used to produce food-grade soybean oil removes those proteins. The FDA recognizes this: highly refined soybean oil is specifically exempted from soy allergen labeling requirements under US law. Most allergists advise that highly refined soybean oil is safe for soy-allergic patients.
The actual soy allergen at Panda Express
Soy sauce contains soy proteins and is used in the cooking sauces for nearly every Panda Express entree. This is the primary soy allergen source — not the cooking oil. Almost all Panda Express entrees are listed as containing soy because of the soy sauce in their preparation.
Individual variation
A small percentage of people with soy allergies do react to highly refined soybean oil. If you have a severe soy allergy, consult your allergist about your specific sensitivity level before making assumptions about what is safe for you personally.
Peanut Allergy — What Actually Matters
Since the cooking oil is not peanut oil, the relevant peanut risk at Panda Express is different from what most people assume.
| Source | Peanut present? | Details |
|---|---|---|
| Cooking oil (soybean) | No | Soybean oil contains no peanuts or peanut proteins |
| Kung Pao Chicken | Yes — direct ingredient | Whole peanuts are an ingredient in the dish |
| All other entrees | Not as ingredient | No peanut ingredients — cross-contamination possible |
| Shared woks | Cross-contamination risk | Woks used for Kung Pao Chicken may be used for other dishes |
For peanut-allergic diners: the cooking oil itself poses no risk. The one item to strictly avoid is Kung Pao Chicken. The shared-wok environment creates a cross-contamination pathway — the severity of this risk depends on your individual allergy and should be assessed with your allergist.

Not every Panda Express item is cooked the same way. The amount of oil used varies significantly by dish:
Deep-fried (higher oil)
Orange Chicken, Hot Orange Chicken, Beijing Beef, Sweetfire Chicken Breast, Sweet & Sour Chicken Breast, Honey Walnut Shrimp — battered and deep-fried before being finished in sauce. These entrees have higher fat content from the oil absorbed during frying.
Wok stir-fried (less oil)
Grilled Teriyaki Chicken, Broccoli Beef, Black Pepper Sirloin Steak, Kung Pao Chicken, String Bean Chicken Breast, Mushroom Chicken, Black Pepper Chicken — cooked in a wok with soybean oil. Less total fat than deep-fried items.
Grilled (minimal oil)
Grilled Teriyaki Chicken — the only grilled entree at Panda Express. Has 10g fat per serving — the lowest among chicken entrees and one of the lowest overall.
Frequently Asked Questions
What oil does Panda Express use for cooking?
Panda Express uses soybean oil for all wok cooking. This is a highly refined soybean oil — not peanut oil, not canola oil, not a vegetable oil blend. The soybean oil is used across all Panda Express restaurants for stir-frying entrees and sides.
Does Panda Express cook in peanut oil?
No. Panda Express uses soybean oil, not peanut oil. The assumption that Panda Express uses peanut oil is common — it comes from the association between Chinese-American cooking and peanut oil — but it is incorrect. Panda Express has confirmed soybean oil as its cooking oil.
Is Panda Express soybean oil safe for soy allergies?
For most people with soy allergies, yes. Highly refined soybean oil has the soy proteins removed during processing — those proteins are what trigger allergic reactions. The FDA exempts highly refined soybean oil from soy allergen labeling requirements for this reason. However, a small subset of people with soy allergies react even to refined oil; consult your allergist if unsure.
What items at Panda Express actually contain peanuts?
Only one item: Kung Pao Chicken. It contains whole peanuts as a direct ingredient. All other Panda Express entrees do not list peanuts as an ingredient. However, shared woks mean cross-contamination from Kung Pao Chicken peanuts is possible for any dish prepared in the same kitchen.
Why does Panda Express use soybean oil instead of peanut oil?
Soybean oil has a high smoke point similar to peanut oil, making it suitable for high-heat wok cooking. It is also less expensive than peanut oil at the volume a large chain requires. From a practical standpoint, soybean oil delivers similar cooking performance at lower cost — a common choice for fast-food chains that need consistent results at scale.
Does the cooking oil at Panda Express affect soy allergy?
Typically not. Highly refined soybean oil has soy proteins removed, so it does not trigger soy allergic reactions in most people. The primary soy allergen exposure at Panda Express comes from soy sauce, which is used in the cooking sauces for nearly every entree. If you have a soy allergy, the soy sauce — not the cooking oil — is the meaningful allergen to be aware of.
Is Panda Express food fried in oil?
Panda Express uses wok frying rather than deep frying for most dishes. Entrees like Orange Chicken are battered and deep-fried before being tossed in sauce. Other entrees are stir-fried in a wok with soybean oil. The cooking method varies by item — battered items (Orange Chicken, Sweetfire Chicken Breast, Beijing Beef) involve more oil than stir-fried entrees (Grilled Teriyaki Chicken, Broccoli Beef).
Does peanut oil use at restaurants affect peanut allergy?
Highly refined peanut oil (like soybean oil) has peanut proteins removed and is generally safe for peanut allergies. Unrefined or cold-pressed peanut oil retains peanut proteins and is a real allergen risk. Since Panda Express does not use peanut oil at all, this distinction is moot for Panda Express specifically — the relevant peanut risk is Kung Pao Chicken as a direct-ingredient item and cross-contamination in shared woks.
