Co-op brings back Roast Potato crisps for Christmas 2026
Co-op has confirmed the line-up for its 2026 Christmas crisps range, and it is one of the more interesting festive snack stories of the year so far. Three flavours make up the collection: the returning Irresistible Ultimate Roast Potato Crinkle Cut Crisps, the returning Irresistible Pigs in Blankets Crinkle Cut Crisps, and a genuinely new addition, Irresistible Wagyu Beef & Caramelised Onion Flavour Crisps. All three are part of the Co-op Irresistible range, sold in 150g bags at £1.75 each, and all use British potatoes hand-cooked in small batches according to Co-op.

For anyone who has been searching for roast dinner flavour crisps every December without luck, this is genuinely good news. The Roast Potato flavour first launched back in 2019, built up what Co-op describes as a cult following, then quietly disappeared from shelves in 2023. According to Natalie Dawe, Crisps, Snacks and Nuts Development Manager at Co-op, the comeback is a direct response to customer requests, with shoppers repeatedly asking “where did your roast potato crisps go” and pushing for their return. That kind of grassroots demand is unusual for a supermarket own label crisp, and it is a decent reminder that discontinued flavours do sometimes come back if enough people ask.
What is in the 2026 range
Here is the full breakdown of what Co-op is putting on shelves this Christmas, based on details confirmed by Co-op and UK trade press coverage:
- Irresistible Ultimate Roast Potato Crinkle Cut Crisps (150g, £1.75) – returning after being discontinued in 2023, seasoned with Cornish sea salt, extra virgin olive oil, garlic, rosemary and black pepper
- Irresistible Pigs in Blankets Crinkle Cut Crisps (150g, £1.75) – a returning favourite from previous festive ranges
- Irresistible Wagyu Beef & Caramelised Onion Flavour Crisps (150g, £1.75) – brand new for 2026, the first time this flavour has appeared in the Co-op Irresistible line-up
All three come in the same crinkle cut format and the same 150g pack size, which makes them easy to line up on a table for a festive sharing spread alongside Christmas crisps multipack options if you are catering for a bigger group.
Why roast dinner flavour crisps keep coming back
Roast dinner flavours are one of the more reliable seasonal trends in UK crisps and snacks. Retailers and manufacturers return to the theme every autumn and winter because it taps into something shoppers already associate with the time of year, without needing much explanation on pack. Co-op is not alone in leaning into this territory. Other supermarkets and crisp brands have run their own versions of turkey dinner, pigs in blankets, and roast potato flavoured snacks over the past few Christmases, and the format tends to sell well as a novelty for parties, work do’s, and Boxing Day leftovers spreads.
What makes the Co-op story slightly different is the “comeback by demand” angle. Most seasonal flavours are simply relaunched on a yearly cycle because they performed well the previous year. Roast Potato had actually been dropped entirely for three years before Co-op brought it back, which suggests the retailer saw enough ongoing customer requests to justify reviving a line rather than just refreshing an existing one. If you want to compare how it stacks up against other beef flavoured crisps already available, the new Wagyu Beef & Caramelised Onion flavour is a useful place to start, since caramelised onion crisps tend to be a consistently popular combination across UK brands.
Ingredients and allergen information
Co-op has confirmed the seasoning for the Roast Potato flavour as Cornish sea salt, extra virgin olive oil, garlic, rosemary and black pepper, and states that all three Christmas varieties use British potatoes, hand-cooked in small batches. Co-op has not published full allergen or vegan and vegetarian status for the new range at the time of writing, so if any of those matter to you, check the pack or Co-op’s own product page before buying, since ingredients and allergen advice can change between batches. We will not guess at dietary status here, but if you are specifically after crisps confirmed as suitable for vegans, that guide is a safer starting point until Co-op confirms the details for this particular range.
Where to buy the Co-op Christmas crisps range
The range is rolling out in Co-op stores nationwide now, priced at £1.75 per 150g bag. Co-op crisps, including previous Irresistible limited edition flavours, have also shown up on Amazon UK through Co-op’s own grocery storefront, so it is worth checking Co-op Irresistible crisps if your nearest store has not stocked the new flavours yet or you would rather order online. Availability of specific new flavours on any online marketplace can lag behind in-store rollout by a few weeks, so if you cannot find the exact Wagyu Beef or Pigs in Blankets listing straight away, it is worth checking back closer to December.
If you are stocking up for a party rather than just picking up one bag for yourself, it is worth browsing more widely for sharing bags of crisps so you can mix the new Co-op flavours in with other festive and classic options.
How the range fits into the wider festive crisp calendar
Christmas crisp ranges from UK supermarkets typically land between late September and November, giving shoppers a good couple of months to try flavours before the big day. Co-op’s timing this year fits that pattern, with the range described as rolling out through September 2026. That gives plenty of time to try all three flavours, decide which one is going on the table for Christmas Day itself, and stock up again if a particular flavour proves popular with family or guests.
A few practical points worth keeping in mind if you are planning around this release:
- All three flavours are 150g bags, so four bags gives you 600g, a reasonable amount for a small gathering
- Pricing is consistent across the range at £1.75 per bag, so there is no need to hunt for a “best value” flavour among the three
- The range is Co-op exclusive as an own label product, so you will not find identical flavours from other supermarkets, though similar themed crisps do exist elsewhere
- Because Roast Potato was previously discontinued, stock levels and how long it stays on shelves this time round are not guaranteed, so do not assume it will still be there in January
Closing summary
Co-op’s 2026 Christmas crisps range brings together a genuine comeback in Roast Potato Crinkle Cut, a returning Pigs in Blankets Crinkle Cut, and a brand new Wagyu Beef & Caramelised Onion flavour, all at 150g and £1.75 a bag. The Roast Potato return in particular is a nice example of a supermarket actually listening to repeated customer requests rather than just running a yearly refresh. If you have missed roast dinner flavoured crisps since 2023, or you fancy trying something new alongside familiar festive favourites, this range is worth adding to your Christmas shopping list, in store or via Co-op’s own listings on Amazon crisps and snacks.
