Contrary to a common misconception, Chick-fil-A does not use peanut oil to cook its signature Waffle Potato Fries. While the company has long been associated with cooking in peanut oil, this practice is specifically for its fried chicken menu items. For consumers with peanut allergies, this is a crucial detail, though it's not the end of the story when considering food safety.
The Short Answer: Canola Oil for Fries, Refined Peanut Oil for Chicken
Chick-fil-A's official website clarifies that its waffle-cut potatoes are cooked in canola oil. This distinguishes the process from the company's trademark fried chicken, which is pressure-cooked in 100% refined peanut oil. The use of different oils for different products is a key part of their food preparation strategy, but it introduces an important layer of complexity for allergy awareness.
Understanding Chick-fil-A's Frying Practices
To ensure both consistency and flavor, Chick-fil-A uses specific oils for its different fried offerings. For decades, the chain has relied on refined peanut oil for its chicken. Refined oil has a high smoke point, which is ideal for achieving a crispy exterior without burning, and provides a clean, neutral flavor that enhances the chicken's seasoning. For the waffle fries, canola oil serves a similar purpose, yielding a crispy exterior and fluffy interior without interfering with the potato's taste. The decision to use different oils reflects a precise approach to food preparation, but it does not eliminate all risks related to allergens.
Important Considerations for Customers with Peanut Allergies
While the fries themselves are not cooked in peanut oil, individuals with severe peanut allergies should still proceed with caution. The FDA exempts highly refined oils, like the one used for Chick-fil-A's chicken, from being labeled as major food allergens because the refining process removes the proteins that cause allergic reactions. However, this does not mean the restaurant is entirely risk-free. Here's why:
- Cross-Contamination: Chick-fil-A locations use shared cooking and preparation areas. While the fryers for the chicken and fries are separate, the risk of cross-contamination exists in any shared kitchen environment. Allergens can be transferred through hands, utensils, or airborne particles, making it impossible for the company to guarantee that any item is completely free from all allergens.
- Individual Sensitivity: Not all individuals with peanut allergies react the same way to refined peanut oil. Some may be more sensitive than others, and it is always recommended that anyone with a severe allergy consult a healthcare professional before consuming food from a restaurant with known allergen presence.
- Recent Recipe Changes: As of early 2025, Chick-fil-A has reportedly changed the recipe for its waffle fries to include pea starch. For people with certain legume allergies, this is a new and significant concern. Pea protein can cause cross-reactivity with peanuts for some individuals, adding another potential risk factor.

Comparison of Frying Oils at Chick-fil-A
| Feature | Chick-fil-A Fried Chicken | Chick-fil-A Waffle Fries |
|---|---|---|
| Primary Cooking Oil | 100% Refined Peanut Oil | Canola Oil |
| FDA Allergen Status | Exempt (highly refined) | Not an allergen concern for peanuts |
| Associated Allergens | Peanuts (in refined oil, but risk is low) | Peas (due to new pea starch additive) |
| Cross-Contamination Risk | Yes, due to shared kitchen environment | Yes, due to shared kitchen environment |
| Flavor Impact | Neutral, allowing chicken's seasoning to shine | Neutral, allowing potato's flavor to be primary |
| High Smoke Point | Yes, ideal for high-temperature pressure cooking | Yes, suitable for frying purposes |
Conclusion
While Chick-fil-A does use peanut oil, it's crucial to remember that it is reserved for the chicken and not the fries. The waffle fries are cooked in canola oil, a different fryer. However, the use of different oils in the same kitchen and the potential for cross-contamination means that no menu item can be guaranteed allergen-free. For customers with peanut allergies, the highly refined nature of the oil used for chicken means the risk of a reaction from the oil itself is minimal, but risks still exist, especially with the recent addition of pea starch to the fries. It is always best for individuals with food allergies to be vigilant, communicate their concerns to restaurant staff, and consult with a medical professional regarding their specific sensitivities. You can find more information about refined peanut oil's allergen status on the National Peanut Board's website.
