Let’s start with the blunt truth: McDonald’s UK does not have a certified gluten-free menu. The kitchens are shared, the equipment is shared, and the company itself says it cannot guarantee that any item is completely free from cross-contamination. If you have coeliac disease, that sentence matters more than anything else in this guide — please read the coeliac section below before ordering anything.
That said, “no certified gluten-free menu” is not the same as “nothing you can eat.” Several items on the UK menu are made without gluten-containing ingredients, and McDonald’s UK publishes a list of them. The UK picture is also notably better than the American one: in the US, McDonald’s fries contain wheat-derived ingredients, while in the UK they don’t. So if you’ve read American articles telling you the fries are off-limits, that advice doesn’t apply here.
This guide is practical information, not medical advice. Menus change, recipes change, and practices can vary between restaurants. When in doubt, ask the crew in the restaurant — they have access to the current allergen information for everything they serve.
McDonald’s UK’s official position
McDonald’s UK is fairly transparent about this. Its official help pages state that the following items are made without wheat-containing ingredients: French Fries, Hash Browns, Shaker Side Salad, Carrot Sticks and Fruit Bags. It also says plainly that because of how its kitchens work, it cannot guarantee that cross-contamination won’t happen.
There is a meaningful distinction hiding in that wording: “wheat-free” is not quite the same as “gluten-free.” Gluten comes from wheat, barley and rye, so something can be wheat-free while still containing traces of barley or rye. In practice, for the items listed above, the risk is about kitchen cross-contact rather than hidden barley — but it’s worth knowing the difference when you’re reading labels and FAQs.
The most reliable sources for current information are the allergen booklet available in every UK restaurant and McDonald’s UK’s online nutrition calculator, which carries full ingredient declarations. Both are updated when recipes change, which makes them more trustworthy than any third-party guide — including this one.
Fries and hash browns: the dedicated fryer question
The fries question comes up constantly, so let’s settle it properly. In the UK, McDonald’s fries are cooked in dedicated fryers using a non-hydrogenated vegetable oil — they are not fried in the same vats as breaded chicken or fish products. Hash browns are treated the same way. This is the single biggest reason the UK gluten-free picture is better than the US one.
Practical takeaway: if you’re avoiding gluten as a preference or have a mild sensitivity, the fries and hash browns are widely considered the safest hot items on the UK menu. If you have coeliac disease, the decision is yours to make with proper caution — see the coeliac section below.
What you can order
With all of the above in mind, here are the items most commonly considered suitable when avoiding gluten in the UK:
- French fries (small, medium or large) — small from around £1, medium around £1.10–£2.20, large around £1.70–£2.70. The headline gluten-free-friendly item. Cooked in dedicated fryers; cross-contamination risk exists but is considered low.
- Hash brown — under £1. Breakfast-only, cooked the same way as the fries. One of the cheapest items on the menu.
- Fruit bag — usually around £1. A bag of apple slices and grapes. Naturally gluten-free and the safest thing on this list.
- Carrot sticks — usually around £1. Another naturally gluten-free option, popular with kids and available in Happy Meals.
- Pineapple stick — usually around £1. A simple fruit option with nothing to worry about.
- Shaker Side Salad — from about £1.09. The salad itself is made without gluten-containing ingredients; order it with the balsamic dressing and skip any extras you’re unsure about.
- Plain burger patties — prices vary. You can order beef patties on their own, without the bun — the kiosks and app both allow customisation. The patties themselves are 100% beef with salt and pepper, but they’re cooked on shared grills, so cross-contact is possible.
- Bacon, sausage patties and eggs — customise a breakfast order to drop the muffin. A sausage patty or a fried egg on its own is made without gluten-containing ingredients, though again from shared cooking equipment.
- A few McFlurry flavours — around £1.49–£2.60. Some flavours, such as Crunchie, are made without gluten-containing ingredients, while biscuit-based ones like Oreo and Maltesers-style toppings contain wheat. Toppings rotate frequently, so always confirm in the restaurant before ordering.
Gluten-free breakfast options
Breakfast runs until 11:00am every day, and the morning menu is actually one of the easier places to eat gluten-free:
- Hash brown — under £1. The star of the gluten-free breakfast. Cooked in the dedicated fryers like the fries.
- Customised McMuffin without the muffin — roughly the price of the standard item (around £3–£4). Order a Bacon & Egg or Sausage & Egg McMuffin with no muffin and you get the egg, meat and cheese in a box. It’s not glamorous, but it works.
- Porridge — around £1. Made with oats, which are naturally gluten-free but very often contaminated with wheat during growing and processing unless certified. McDonald’s UK does not advertise its porridge as gluten-free, so treat this one with caution and ask in the restaurant.
- Fruit bag — usually around £1. Available at breakfast too, and the safest choice on the board.
What to avoid
Just as important as what you can order is what you can’t. These all contain gluten as a core ingredient:
- All buns, muffins, tortilla wraps and pancakes. The obvious ones — every burger bun, McMuffin, breakfast wrap and pancake contains wheat.
- Chicken McNuggets and Chicken Selects. All breaded or battered. (The old Veggie Dippers were also breaded, but they were removed from the UK menu in February 2026.)
- Breaded chicken burgers — the McCrispy, Mayo Chicken, McChicken Sandwich and similar all have wheat in the coating.
- Mozzarella Dippers and Cheese Melt Dippers. Breaded, so they contain wheat.
- Apple pie. The pastry contains wheat.
- Oreo, Smarties and Maltesers McFlurrys. The biscuit and chocolate toppings in these contain wheat. A couple of other flavours may be fine — check in the restaurant.
- Milkshakes. The shakes themselves are generally made without gluten-containing ingredients, but they’re prepared on shared equipment and McDonald’s doesn’t list them among its wheat-free items, so coeliacs should be cautious.
- Most sauces and dips. Some are fine, some aren’t, and recipes change. The allergen booklet in the restaurant is the definitive source.
How to check allergen information
McDonald’s UK gives you several ways to check what’s in your food:
- The allergen booklet. Every UK restaurant has one, and staff can show it to you on request. This is the most authoritative in-restaurant source.
- The online nutrition calculator. McDonald’s UK publishes full ingredient declarations for everything on the menu. Check it before you visit if you’re planning an order.
- The app and kiosks. The McDonald’s UK app and self-service kiosks carry allergen information for menu items, which is handy for checking before you commit to an order.
- Ask the crew. Staff are trained to help with allergen questions. If you’re unsure about anything — a rotating McFlurry flavour, a limited-edition item, how something is cooked — ask. That’s what the information is there for.
One more tip: limited-edition and promotional items are the highest-risk category. The core menu items in this guide have stable recipes that McDonald’s has documented, but a brand-new burger or dessert might contain allergens you’d never expect. Always check limited editions separately.
A note for coeliacs
If you have coeliac disease, please read this carefully. Coeliac disease is an autoimmune condition, not a preference, and even tiny amounts of gluten can cause damage. McDonald’s UK states clearly that it cannot guarantee any item is free from cross-contamination because of shared cooking and preparation areas, shared equipment and shared utensils.
Some coeliacs in the UK do eat McDonald’s fries and other items from the wheat-free list and are comfortable with the small residual risk. Others aren’t, and both positions are reasonable — it depends on your own sensitivity, your dietitian’s advice, and your comfort level. What you shouldn’t do is treat this guide, or any third-party guide, as a safety guarantee. Talk to your doctor or dietitian, check the current allergen information in the restaurant, and make your own informed decision.

Frequently Asked Questions
Are McDonald’s fries gluten-free in the UK?
Not certified, but they’re the closest thing to it: UK fries are cooked in dedicated fryers with non-hydrogenated vegetable oil and contain no wheat ingredients. McDonald’s won’t guarantee zero cross-contamination, so coeliacs should weigh the small residual risk themselves.
Is anything at McDonald’s safe for coeliacs?
McDonald’s UK says it can’t guarantee any item is completely free from cross-contamination. Some coeliacs choose to eat items from the wheat-free list (fries, hash browns, salads, fruit); others avoid the chain entirely. It’s a personal decision to make with your dietitian.
Are Chicken McNuggets gluten-free?
No. The batter coating contains wheat, and they’re cooked in shared fryers.
Does McDonald’s UK have gluten-free buns?
No. There are no gluten-free bun, muffin or wrap options on the UK menu. The workaround is ordering patties or fillings without the bread.
Are hash browns gluten-free?
They’re made without wheat-containing ingredients and cooked in the dedicated fryers, like the fries. Same cross-contamination caveat as everything else applies.
Why do American guides say the fries aren’t gluten-free?
Because in the US, McDonald’s fries contain wheat and milk-derived ingredients. The UK recipe is different — UK fries don’t contain wheat. Always follow UK-specific guidance for UK restaurants.
Where can I see McDonald’s UK allergen information?
In the allergen booklet available in every restaurant, in the online nutrition calculator, and in the app and kiosk allergen information.
Final thoughts
Eating gluten-free at McDonald’s UK is entirely possible, but it requires going in with your eyes open. The fries, hash browns, salads and fruit options give you a workable meal, the customisation options on kiosks help, and the company’s allergen information is genuinely useful. What you can’t get is a guarantee — and if you’re coeliac, that missing guarantee is the whole conversation. Check the current information, ask in the restaurant, and never let a third-party guide (this one included) overrule your own medical advice.
