In this article I compared 7 major supermarkets and their gluten free ranges to find out which were offering the best range in terms of costs, selection and quality.
Check out each individual supermarket using the relevant links below – this is handy if you have a favourite but want to compare it to other supermarkets out there.
In the 2023 comparison of UK’s largest supermarkets, we found Asda to be the best supermarket for shopping gluten free when considering pricing, the range of gluten free items available and the viewability of products due to their frozen, chilled and ambient gluten free sections.
To see the details for each supermarket, head below and click a link to be taken to the supermarket you want to find out more about.
AND if you want to find out which supermarket is cheapest for shopping gluten free, you can read this comparison article of mine which compared prices for 40 everyday products that are gluten free in 7 major supermarkets.
Be sure to read it after this article if not before!
Asda are well-known for their special deals and generally being able to beat the prices on a lot of products in comparison to other major supermarkets, and when it comes to their gluten free options, there’s no exception.
Asda have 86 products in their own free from range, plus an additional 200 or so products which are marketed gluten free and provided by other brands.
Of course, there are plenty more gluten free products to be found in Asda that are “accidentally gluten free” or naturally gluten free too.
You may have seen in the price comparison article of mine that many of Asda’s “Just Essentials” range are “accidentally gluten free”, meaning they have no gluten ingredients in them and no may contain warnings for gluten either.
Buying products that are outside of the designated free-from zones that fall into this “accidentally gluten free” category, means saving extra money because you’re not buying specifically marketed gluten free products.
Asda also have a brilliant dry goods free-from section in all of their supermarkets, as well as a free-from chilled section and a free-from frozen section.
This makes the search for Asda’s range of free from foods very easy. Not all major supermarkets have the 3 of these free from sections!
In addition, Asda have a Free From category on their website for those shopping online which some of the other supermarkets don’t have yet.
This makes it super easy to see everything free from in one click from Asda’s homepage, unlike other supermarkets where you’ll be making 3-5 clicks to see those free from products.
Remember to use the chart in this article to find some deals OUTSIDE of the free from zones too, because there’s loads of bargains on those “accidentally gluten free” foods at Asda to be had.
Check out this article of mine to see all of the soups Asda have that are gluten free
(including all those “accidentally gluten free” ones that can save you money!).
Tesco have 96 products in their own free from range, which is pretty respectable and also pretty reasonable when it comes to pricing.
They regularly have these products on offer with the clubcard too, so if you don’t already have a clubcard, now is the time to get one and reap those extra savings on any gluten free items.
There’s also another 150 or so products which are marketed gluten free and available in Tesco’s stores.
Just be mindful that the smaller shops will always have a smaller selection of these gluten free products, so shopping online or only in the superstores will provide the best number of options!
In comparison to Asda, there’s a few products such as own-brand gluten free plain and self-raising flour which tesco don’t make while Asda do (Asda own is much cheaper than branded!).
Fancy knowing which branded and non-branded ice-creams are gluten free?
I made this A-Z list for all the ice-creams out there so you don’t always have to buy the marketed gluten free ones!
There’s also a noticeably bad supply of gluten free ready made pastry in Tesco’s I find!
I cannot tell you the amount of times I’ve looked for either frozen or fresh gluten free puff and shortcrust pastry and have either not been able to get it at all at Tesco’s or it’s always been out of stock.
For your pastry needs, I’ve always found Asda to be the cheapest and have the most options (frozen and fresh).
As always, look outside of the designated free from zones in Tesco stores because there’s many “accidentally gluten free” products to be found which are cheaper than marketed gluten free products.
It’ll show which items (depicted by a * next to the product name) are available outside of the free from aisles, as part of the standard, everyday items, just without a specific gluten free label.
Morrisons have 82 products in their supermarket own range of gluten free products, which is along the same lines as Asda and Tesco.
Their pricing as a whole is generally about the same too, with a few differences here and there on branded gluten free goods.
In addition, they stock about 250 more products which are gluten free from other brands.
In the price comparison I did in this article they were missing 3 items out of the 40 products compared.
These included a gluten free version of coco pops or similar breakfast cereal, a gluten free shortcrust pastry option and also gluten free steak pies of any sort.
Morrisons also have plenty of naturally gluten free and “accidentally gluten free” products in their supermarkets too, meaning you can save some money by buying these and not the marketed gluten free items all the time.
Morrisons are also one of the only supermarkets to offer gluten free breadcrumbs in a ready made form, alongside Ocado!
Fancy finding out which soups at morrisons are gluten free?
Including all those “accidentally gluten free” ones which can save you money compared to buying labelled gluten free items?
Like Asda and Morrisons, Sainsbury’s make it easy for you to find their free from sections online with just a couple clicks from their homepage.
Within their gluten free section both online and in supermarkets, you’ll find 71 products within Sainsbury’s own gluten free range, plus a further 150 or so gluten free products provided by other brands.
Of course, there is more naturally gluten free foods or “accidentally gluten free” foods to be found in the normal aisles of Sainsbury’s too, just as I’ve mentioned with all the other supermarkets above.
By “accidentally gluten free”, we mean a product which is not marketed as or labelled as being gluten free, but instead, one that has no gluten ingredients listed and no may contain warnings for gluten either.
These accidentally gluten free products are not only gluten free but are generally much cheaper because they don’t market themselves as specific gluten free products in a free from range.
Sainsbury’s are a good choice for gluten free and one way to make the most of your shop is to apply for and use a nectar card with them.
When you shop regularly, the nectar card prices and offers available will become tailored to you and so you’ll no doubt see some of your gluten free products at a lower price!
Compared to the other supermarkets in the price and availability comparison of 40 gluten free products at 7 supermarkets in this article, Sainsbury’s had 37/40 products and came in as second best after Asda.
If you factor in the price of the 37 products plus what you might expect to pay for the 3 missing ones.
Waitrose have 28 products in their own range of gluten free items, which is a lot less than the other supermarkets out there.
Within the 28 products you’ll find staples like bread, pasta, porridge oats, muesli and some treats like cakes, cake slices and biscuits.
Aside from their own brand, there’s also many premium products and branded gluten free items to choose from, although some of these are generally priced higher.
You definitely can’t shop Waitrose own-brand ONLY, if you need more than the items listed above which (lets face it) most people are going to if they’re living gluten free!
Like the other supermarkets, you’ll find many things outside of the designated free from aisle which are either naturally gluten free, or “accidentally gluten free”.
This simply means a product which has not been marketed as being gluten free but which has no gluten ingredients listed and allergen warning of any sort for gluten either.
In the 40 product comparison in this article, Waitrose had 36/40 items.
Those that were missing were gluten free shortcrust pastry, gluten free chicken nuggets, gluten free chicken pies of any kind and gluten free ready made breadcrumbs.
One of the best things about shopping gluten free at Waitrose is their own brand gluten free oats because (unlike all the other supermarket own brands) Waitrose uses jumbo oats rather than the small rolled oats.
They’re also pretty cheap for 1kg (£4.30) and with the added health benefits of eating jumbo oats, it makes for a good choice of product if you like porridge!
Aldi and Lidl have a huge selection of products which are gluten free, but in both stores they are often not in a designated “free-from” aisle.
This is the case in many supermarkets as they all have “hidden” gluten free items. Aldi’s gluten free products are scattered through-out the stores, some of which are labelled gluten free and others which are not.
