Direct Answer (AEO / Fast Answer): Chick-fil-A uses 100% refined peanut oil for all pressure-fried breaded chicken and 100% canola oil for Waffle Potato Fries and Hash Browns. According to the FDA, highly refined oils do not contain allergenic protein, but those with severe peanut allergies must exercise caution. Standard breaded chicken contains wheat, milk, egg, and soy. Sesame is present on standard toasted white buns.
Navigating fast food with food allergies can be stressful. Whether you or a family member is allergic to peanuts, dairy/milk, eggs, wheat/gluten, soy, tree nuts, or sesame, understanding how Chick-fil-A prepares its food is critical for dining safely.

2. The Peanut Oil Policy: What You Must Know
Chick-fil-A has cooked its pressure-fried chicken in 100% refined peanut oil since founder Truett Cathy opened the Dwarf Grill in 1946.
Why Refined Peanut Oil Is Different
- Refining Process: Highly refined peanut oil undergoes a rigorous bleaching and deodorizing process that extracts almost 100% of the peanut protein (the specific component that triggers IgE-mediated anaphylactic allergic reactions).
- Medical Consensus: The American College of Allergy, Asthma & Immunology (ACAAI) states that most peanut-allergic individuals can safely consume refined peanut oil.
- Cold-Pressed / Unrefined Peanut Oil: Chick-fil-A does NOT use unrefined or cold-pressed peanut oil.
- Safety Precaution: If your allergist has advised you to strictly avoid all peanut-derived oils, stick to Grilled Chicken, which is cooked on dedicated cast-iron grills without peanut oil.
3. Dedicated Fryer Separation (Canola Oil for Potatoes)
A major point of safety for potato and allergen lovers:
- Canola Oil Only: Waffle Potato Fries and morning Hash Browns are cooked in dedicated open fryers using 100% canola oil.
- No Shared Fryers with Breaded Chicken: Chick-fil-A kitchen standards prohibit frying breaded chicken or nuggets in the waffle fry vats.
4. Top Allergen breakdowns
Dairy & Milk Allergies
- Items to Avoid: All breaded chicken (milk wash in batter), buttermilk biscuits, cheese slices, mac & cheese, creamy dressings, milkshakes, and Icedream.
- Safe Options: Grilled Nuggets, Grilled Chicken on Gluten-Free Bun (without cheese), Waffle Potato Fries, Fruit Cup, and BBQ / Polynesian / Sweet & Spicy Sriracha sauces.
Egg Allergies
- Items to Avoid: Breaded chicken (egg wash used before breading), breakfast scrambled eggs, mayonnaise, Garden Herb Ranch, and Avocado Lime Ranch.
- Safe Options: Grilled Nuggets, Grilled Chicken Sandwich, Waffle Fries, Honey Mustard Sauce, Polynesian Sauce, and Barbeque Sauce.
Sesame Allergies
- Following the FASTER Act, Chick-fil-A updated its supplier notifications: standard toasted white buns contain sesame flour.
- Sesame-Free Breads: The Multigrain Brioche Bun, the English Muffin, and the Certified Gluten-Free Bun do not contain sesame ingredients.
5. How to Place an Allergy Order (Step-by-Step)
- In-Store / Drive-Thru: Inform the order taker: “I am ordering for a guest with a severe [Allergen] allergy. Please mark this as a Red Flag Allergy.”
- Kitchen Response: The register flags the ticket in bright red. The kitchen team washes hands, changes into fresh food-safety gloves, wipes down the prep station, and prepares the order using clean tongs and packaging.
- Mobile App: In the Chick-fil-A One app, tap on any menu item $\rightarrow$ click Nutrition & Allergens $\rightarrow$ select individual allergen filters before placing your order.
