Eating at Zaxby’s with celiac disease, IBS or food allergies

It depends on what you need to avoid and on what Zaxby’s current allergen guide says, which you should read yourself. As of October 2026, Zaxby’s US menu page links to a document labeled Nutrition/Allergens. We tried to open that guide for this article and couldn’t, so this guide doesn’t describe which Zaxby’s items contain which allergens. Nothing here should be read as a menu fact about Zaxby’s.

Instead, this guide explains what usually matters at a fried chicken restaurant, the questions worth asking at Zaxby’s, and how to read an allergen chart when you get it. The general principles come from the Celiac Disease Foundation, NIDDK, FARE and Monash University.

When we checked Zaxby’s US menu page in October 2026, it was organized into Chicken Fingerz and wings meals, sandwich meals, Zalads (salads), sides and extras, treats, kids meals, sauces and dressings, and drinks, plus limited-time items such as flavored wings, quesadillas and loaded fries. For each of these, the questions are a little different.

Those are questions, not answers. Zaxby’s own allergen guide and the staff at your restaurant are where the answers come from.

At fried chicken restaurants, the most common gluten sources are the breading on the chicken and the bun on sandwiches. The other big one is the fryer. The Celiac Disease Foundation lists fried foods cooked in oil shared with breaded products, and French fries in particular, as common cross-contact risks.

• Ask whether an item is breaded, and with what. Wings may or may not be breaded depending on the restaurant and style.
• Ask whether fries share oil with breaded chicken at that location.
• Ask about grilled chicken if it’s offered: what the seasoning or marinade contains, and whether it’s cooked on a surface shared with breaded items.
• Ask about salad toppings like croutons or crispy toppings, which are often wheat-based.

The NIDDK explains that cross-contact can happen when food is prepared or served, and suggests checking the menu online, telling staff about celiac disease and asking about preparation. A chain allergen chart describes ingredients; it usually can’t tell you what happens in the fryer at one location. How much risk is acceptable is a decision to make with your gastroenterologist or dietitian. Our guides to eating out with celiac disease and what gluten-free does and doesn’t mean go further.

Monash University lists garlic, onion, wheat-based breads, honey, high fructose corn syrup and cow’s milk among higher-FODMAP foods, and plain cooked poultry and potato among lower-FODMAP ones. It also notes that marinated or processed poultry can be different, which describes most fast-food chicken.

• Wing sauces and dry rubs: seasoning blends often include garlic and onion powder. Honey-based sauces add honey. Ask what’s in the specific sauce or rub.
• Dipping sauces and dressings: creamy dressings often contain milk, egg, garlic and onion. Ask for them on the side so you control the amount.
• Breading: usually wheat-based, which matters for fructans as well as gluten.
• Cheese and shakes: if lactose is one of your triggers, note where cheese, ranch-style dressings and shakes appear.

With FODMAPs, portion size matters too, so a few pieces with sauce on the side may sit differently from a large platter. Our guides to hidden garlic and onion, FODMAP portion sizes and eating out with IBS explain more.

When you open Zaxby’s current Nutrition/Allergens guide, a few things are worth checking:

1. Find the date. Allergen guides are revised, so make sure you’re reading the current one.
2. Check which allergens it covers. In the US, the FDA’s nine major food allergens are milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame. If you have an allergy outside those, such as mustard or celery, you’ll need to ask.
3. Read the fine print. Look for any statement about shared fryers, shared equipment, frying oil or items not listed, such as limited-time offers.
4. Look at sauces and toppings separately. A meal’s allergens are the sum of its parts.
5. Remember the limits. A blank cell means the item isn’t listed as containing that allergen. It doesn’t mean it’s free from cross-contact.

FARE explains that cooking doesn’t remove an allergen and that shared utensils can carry it from one food to another. Its dining-out advice also says the grill and frying oil are ripe for cross-contact, and suggests avoiding fried foods unless you know how they’re prepared. Our guide to food allergies and the major allergens explains the US and EU/UK allergen lists.

1. Read Zaxby’s current allergen guide online ahead of your visit, including the notes at the bottom.
2. Tell staff at the start of the order about your allergy or celiac disease, and ask for a manager if you have questions.
3. Ask about the fryer for anything fried, including fries and wings.
4. Order sauces and dressings on the side, and change items from the start rather than asking for something to be removed later.
5. Go at a quieter time if you can. FARE suggests choosing times when the kitchen is less busy.
6. If an answer isn’t clear, skip it. It’s fine to eat something you’ve brought or choose somewhere else.

Helpful phrases: "I have celiac disease. Are the fries cooked in the same oil as the breaded chicken?", "I have a milk allergy. Which sauces and dressings contain milk?" and "Is there garlic or onion in this dry rub?"
