Does Panda Express Cook in Peanut Oil?
No — Panda Express uses soybean oil, not peanut oil. This is one of the most common misconceptions about Panda Express ingredients. Here is what oil is actually used, what it means for peanut and soy allergies, and the one item that does contain real peanuts.
Quick Answer
Panda Express uses soybean oil — not peanut oil. The only item that contains peanuts as a direct ingredient is Kung Pao Chicken. Soybean oil is highly refined, which means the soy proteins that cause allergic reactions are removed — most people with soy allergies tolerate it safely. The main soy allergen at Panda Express comes from soy sauce in cooking sauces, not the cooking oil.
What Oil Panda Express Uses — Confirmed
Panda Express uses soybean oil for wok cooking across its restaurants. This is not vegetable oil blend, canola oil, or peanut oil — it is specifically soybean oil.
Why people assume peanut oil
The association between Chinese-American restaurant cooking and peanut oil is strong. Many traditional Chinese recipes call for peanut oil because of its high smoke point and mild flavor. Panda Express is a large chain operation that standardized on soybean oil, which has similar properties at lower cost. The taste confusion is real — high-heat wok cooking in soybean oil can produce similar flavor notes to peanut oil cooking.
| Oil type | Allergy proteins | Allergy risk | At Panda Express |
|---|---|---|---|
| Peanut oil (unrefined) | Contains peanut proteins | High peanut allergy risk | Not used at Panda Express |
| Peanut oil (refined) | Proteins mostly removed | Generally lower risk | Not used at Panda Express |
| Soybean oil (refined) | Soy proteins removed | Generally safe for soy allergy | ✓ Used at Panda Express |
| Soy sauce | Contains soy proteins | Soy allergy risk | Used in cooking sauces |

What Items Actually Contain Peanuts
There is exactly one Panda Express entree that lists peanuts as a direct ingredient.
| Item | Peanuts as ingredient? | Notes |
|---|---|---|
| Kung Pao Chicken | Yes — direct ingredient | Whole peanuts in the dish |
| All other entrees | No — not an ingredient | Cross-contamination possible from shared woks |
| Honey Walnut Shrimp | No — not peanuts | Contains tree nuts (walnuts) — different allergen |
| All sides | No — not an ingredient | Cross-contamination possible |
| All appetizers | No — not an ingredient | Cross-contamination possible |
Source: official Panda Express allergen data
Note on Honey Walnut Shrimp: it contains tree nuts (walnuts), which is a separate allergen from peanuts. Tree nuts and peanuts are different food groups — a peanut allergy does not automatically mean a tree nut allergy, though both are common. If you have a peanut allergy, Honey Walnut Shrimp is safe from a peanut standpoint (though not from a tree nut standpoint).

Soybean oil being the cooking oil at Panda Express is often alarming to soy-allergic diners. The reality is more nuanced:
Highly refined soybean oil is generally safe for soy allergies
The refining process removes soy proteins — the components that trigger allergic reactions. The FDA permits highly refined soybean oil to be excluded from soy allergen labeling for this reason. Most allergists consider highly refined soybean oil safe for soy-allergic patients.
Soy sauce is the real soy allergen at Panda Express
Soy sauce contains soy proteins and is the primary soy allergen at Panda Express. It is used in the cooking sauces for most entrees. This is why nearly every Panda Express entree is listed as containing soy — not because of the oil, but because of the soy sauce.
Individual sensitivity varies
A small subset of people with soy allergies react to highly refined soybean oil. If you have a severe soy allergy, consult with your allergist about your individual sensitivity to refined soybean oil before eating at Panda Express.
What This Means for Peanut Allergy
The key facts for peanut-allergic diners at Panda Express:
Cooking oil is soybean oil — not peanut oil
Only Kung Pao Chicken contains peanuts as an ingredient
All other entrees are peanut-free by ingredient
Cross-contamination from Kung Pao Chicken is possible in shared woks
Panda Express does not maintain a peanut-free kitchen
Cross-Contamination Risk at Panda Express
All Panda Express dishes are cooked in shared woks. Kung Pao Chicken — which contains whole peanuts — is cooked in the same woks used for other dishes. This creates a realistic cross-contamination pathway for peanuts.
Practical guidance by allergy severity
Mild peanut sensitivity
Avoid Kung Pao Chicken. Ordering other entrees carries low but non-zero cross-contamination risk.
Moderate peanut allergy
Avoid Kung Pao Chicken and inform staff of your allergy. Cross-contamination risk from shared woks is real and should be factored in.
Severe peanut allergy (anaphylactic)
The shared-wok kitchen environment is a significant risk factor. Contact Panda Express directly about allergen protocols at your specific location. This is a personal medical decision to make with your allergist.
Frequently Asked Questions
Does Panda Express cook in peanut oil?
No. Panda Express uses soybean oil for wok cooking — not peanut oil. This is the confirmed oil used across Panda Express restaurants. The widespread belief that Panda Express uses peanut oil comes from the association between Chinese-American food and peanut oil, but Panda Express specifically uses soybean oil.
Does Panda Express have peanuts in their food?
Only one item contains peanuts as a direct ingredient: Kung Pao Chicken. All other Panda Express menu items do not contain peanuts as an ingredient. However, because peanuts are present in the kitchen for Kung Pao Chicken, cross-contamination in shared woks is possible for all dishes.
Is Panda Express safe for peanut allergies?
This depends on allergy severity. Panda Express uses soybean oil (not peanut oil), so the cooking oil itself is not a peanut risk. However, Kung Pao Chicken contains whole peanuts, and all dishes are cooked in shared woks. Cross-contamination is possible. For mild peanut sensitivities, avoiding Kung Pao Chicken and ordering carefully may be sufficient. For severe peanut allergies, the shared-wok environment poses real cross-contamination risk.
What oil does Panda Express use?
Panda Express uses soybean oil for wok cooking. This is a highly refined oil, which means the protein structures that cause soy allergic reactions have been removed during processing. Most people with soy allergies tolerate highly refined soybean oil without reaction. The soy allergen exposure at Panda Express primarily comes from soy sauce used in cooking sauces, not the soybean oil itself.
Does soybean oil at Panda Express cause soy allergic reactions?
Typically not. Highly refined soybean oil undergoes processing that removes soy proteins — the component responsible for allergic reactions. The FDA exempts highly refined oils from soy allergen labeling for this reason. Most people with soy allergies can consume highly refined soybean oil safely. The meaningful soy allergen at Panda Express comes from soy sauce used in cooking, not from the oil.
Why do people think Panda Express uses peanut oil?
The assumption comes from two sources: the association between Chinese-American cooking and peanut oil, and Kung Pao Chicken containing peanuts as an ingredient. Some customers taste what they interpret as 'peanutty' flavor in the wok cooking, which is actually the Maillard reaction and high-heat soybean oil cooking — not peanut oil. Panda Express has confirmed soybean oil as its cooking oil.
Does Kung Pao Chicken at Panda Express have peanuts?
Yes. Kung Pao Chicken is the only Panda Express entree that contains peanuts as a direct ingredient. The peanuts are whole or coarsely chopped and are visible in the dish. Anyone with a peanut allergy should strictly avoid Kung Pao Chicken and should note that peanut cross-contamination is possible in shared woks used for other dishes.
Is the cooking oil at Panda Express vegan?
Yes. Soybean oil is plant-derived and vegan. The cooking oil itself is not an animal product. However, many Panda Express dishes contain non-vegan ingredients (meat, eggs, dairy in some items), so the cooking oil being vegan does not make the dishes vegan overall.
