Updated 12 September 2026 · price from a third party listing
Cheese & Caramelised Onion Toastie sits 2nd of 7 on price in Greggs’ Hot Food section, at £4.65 and 548 kcal. Updated 12 September 2026.
Caramelised onion chutney, sliced mature Cheddar cheese and red onion sandwiched between white bread made with sourdough, topped with béchamel sauce and grated mixed cheese. Guaranteed to be loved by dads, divas and Donna down the street – and all for a good reason.
The £4.65 figure came from a third party listing rather than from Greggs, which means it may reflect a delivery menu. Delivery prices sit above in restaurant prices before any fee is added, so treat this as the ceiling rather than the till price.

Everything You Need to Know About Greggs Cheese & Caramelised Onion Toastie
How to order Cheese & Caramelised Onion Toastie at Greggs
Cheese & Caramelised Onion Toastie is available at the till, on the kiosk screens and through the Greggs app, for collection or for delivery. It is filed under Hot Food. Not every branch stocks it, and the app is honest about that before you pay.
Greggs Cheese & Caramelised Onion Toastie price in 2026
The Greggs Cheese & Caramelised Onion Toastie price in 2026 is £4.65 on the figures we hold. The figure came from a third party listing rather than from Greggs, so read it as a ceiling. Within the Hot Food section that puts it 2nd of 7 on price. Expect more at airport, motorway and station branches than on a high street, and more again through a delivery app.
More protein for similar money
Ham & Cheese Toastie costs about the same at £4.65 and carries 31g of protein against this item's 25g. If the point of the order is to be full for longer, that is the better buy of the two.
Protein for the calories
It gives 4.6g of protein per 100 kcal, against a menu average of 3.9g across everything we hold for Greggs. That is a little better than the menu average, which matters more than the raw protein figure when you are comparing two items of different sizes. On raw protein it ranks 25th of 30 in its section.
A lighter choice in the same section
Southern Fried Chicken Goujons sits in the same part of the menu at 400 kcal, which is 148 fewer than this. That swap is the single biggest change available inside this section, and it needs no substitution or special request at the counter.
What 548 kcal means here
548 kcal is well below the Hot Food average. That is a full meal's worth on its own, before anything else goes on the tray. The 2,000 kcal figure printed on UK menus is a reference intake for an average adult, not a target, and it is the number these percentages are worked against.
Pro Tips for Ordering Cheese & Caramelised Onion Toastie
Built to order
Items like this are assembled to a standard build, and the published figure describes that build. A swap or a dropped filling changes it, and at Greggs that is a normal counter request rather than a special one.
Where it sits on price
1 item costs less than this one in the Hot Food section and 5 cost more, out of 7 we hold a price for. The closest thing to it on price is Ham & Cheese Toastie at £4.65, so those two are the real comparison when you are deciding.
Finding it near you
We list 174 Greggs branches across 4 of the four UK nations, with the Glasgow postcode area holding the most at 27. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Greggs app confirms it in seconds.
