Korean fried chicken is built on a few ingredients that happen to be common allergens wheat in the batter, soy in the sauces, sesame across the menu so if you’re managing a food allergy or intolerance, Bonchon takes a little planning. This Bonchon Allergens guide pulls together what Bonchon’s published allergen information tells us, organised by allergen and by dish, so you can order with more confidence. I’ve kept it honest about where things vary.
IMPORTANT – PLEASE READ
Please read this first. This guide is compiled from Bonchon’s published allergen information and typical recipes. Ingredients, preparation, and frying oils vary by location, and shared fryers create cross-contamination risk. If you have a serious allergy, always confirm directly with your specific restaurant and check Bonchon’s official allergen chart before ordering. This is general information, not medical advice.
The allergens Bonchon tracks
Bonchon’s official allergen chart lists each menu item against these allergens and dietary flags:
Peanut · Tree Nut · Milk · Dairy · Egg · Wheat/Grain · Soy · Shellfish · Seafood · Pork · Beef · Chicken · MSG · Sesame (seed/oil) — plus columns for Vegetarian, Kosher, and Halal.
That’s a thorough list, and it’s the single most useful document for allergy planning. The catch is that it’s published as a chart, so this guide turns the key parts into plain English.
Common allergens by dish (quick matrix)
Use this as a starting point, then confirm specifics with your location. Y = typically contains · — = typically free · ~ = varies, confirm.

Shellfish/seafood applies specifically to Shumai (shrimp), Takoyaki (octopus), the seafood protein options, and Kimchi (fish sauce). Always confirm.
Is Bonchon gluten-free?
Short answer: Bonchon is not a gluten-friendly restaurant, and there is no certified gluten-free menu. Two reasons:
- The batter contains wheat. Bonchon’s signature double-fried coating is wheat-based, so the fried chicken itself is not gluten-free.
- The sauces are soy-sauce-based, and standard soy sauce contains wheat so Soy Garlic, and most glazes, carry gluten too.
The items that are naturally free of gluten ingredients are limited think steamed rice, edamame, pickled radish, and usually kimchi and the cucumber salad. But here’s the honest caveat: shared fryers and prep surfaces mean cross-contamination risk is real, so even these are not safe for someone with celiac disease without confirming how your location prepares them.
If you’re strictly gluten-free, treat Bonchon as a “confirm everything” restaurant and lean on the naturally-GF sides rather than the chicken.
Dairy-free and egg-free at Bonchon
Better news here. The core fried chicken is reported to be dairy-free and egg-free — the allergens to watch on the chicken are wheat and soy, not milk or egg.
Where dairy and egg show up:
- Dairy: anything with mozzarella (Tteokbokki, Bulgogi Fries), parmesan (Seasoned Fries, Fried Zucchini), and the Korean Donuts.
- Egg: mayo-based components — spicy mayo, Kewpie mayo, buttermilk ranch — so Chicken Katsu, Korean Tacos, Takoyaki, Bao Buns, and Coleslaw. Also Bibimbap (scrambled egg) and the donuts.
So a dairy- and egg-free order is very doable: stick to the plain sauced chicken (Soy Garlic, Spicy, Classic Crunch) and skip the cheese- and mayo-topped items.
Nuts and peanut oil – read this if you have a nut allergy
This is the most important section for nut-allergy diners, because it varies by location.
Bonchon’s official chart specifically flags items “manufactured in facilities using peanut oil” with a marker — meaning some locations and supply chains involve peanut oil. At the same time, some individual restaurants have stated they fry in soybean oil and don’t use whole or chopped peanuts. In other words, there is no single nationwide answer on peanut oil.
If you have a peanut or tree-nut allergy, do not rely on a general guide call your specific location and ask directly which oil they fry in and whether any items involve peanut oil, and check the official chart’s peanut-oil notation. This is exactly the kind of question Bonchon staff are used to answering.
Vegetarian and vegan options
Bonchon is chicken-forward, but there are meat-free choices:
- Vegetarian: Edamame, Steamed Rice, Pickled Radish, Kimchi (note fish sauce — see below), Coleslaw, the fries, Onion Rings, Fried Zucchini, the Vegetable Potstickers, and Bibimbap with the tofu or plain option.
- Vegan: the cleanest picks are Edamame, Steamed Rice, Pickled Radish, and the Korean Cucumber Salad. Watch out: Kimchi often contains fish sauce, Coleslaw contains egg, and cheese/parmesan sides contain dairy.
For a fuller breakdown, see our dietary notes on each item page.
Halal and kosher
Bonchon’s chart includes Halal and Kosher columns, but status is decided location by location there’s no nationwide certification. We cover this in depth in our Bonchon halal guide; the short version is to verify meat sourcing, alcohol-based sauce ingredients, and pork cross-contamination with your specific branch.
The two allergens that are almost everywhere: soy and sesame
If you’re allergic to soy or sesame, Bonchon is genuinely difficult:
- Soy is in the sauces, the soy-garlic glaze, the marinades, and the frying oil at many locations it’s hard to avoid across the menu.
- Sesame (seeds and oil) appears across the Korean dishes Bibimbap, Bulgogi, Japchae, House Fried Rice and more.
For severe soy or sesame allergies, this is a confirm-every-item situation, and your safest options are the plainest sides.
How I order when allergens matter
My own approach, from years of doing this for friends and family with allergies:
- Tell the staff first, before ordering — not after. Bonchon staff field allergy questions regularly.
- Ask the three oil-and-prep questions: what oil do you fry in, are fryers shared, and is this item prepped separately?
- Pull up the official allergen chart on your phone and point to the specific item.
- When in doubt, default to the plainest options — plain sauced chicken for wheat/soy-tolerant diners, or naturally-free sides otherwise.
- Re-confirm at each location, because oils and suppliers differ.
Allergen management at Bonchon is absolutely possible — it just rewards asking questions rather than assuming.
