Greggs Cheese & Onion Bake
Greggs Cheese & Onion Bake: Price, Calories & Is It Vegan?
Prices & nutrition checked: September 2026
The Greggs Cheese & Onion Bake — sometimes called a cheese and onion slice or pasty — costs £1.60 at standard high-street stores, rising to £1.80 in City/London branches and £2.15 at franchise locations like airports. Each 141.4g bake packs 436 kcal, making it one of the higher-calorie savoury options, and 25p more expensive than a Steak Bake or Chicken Bake. It’s vegetarian but definitely not vegan — the filling uses a blend of cheeses including mature Cheddar, and the pastry contains milk. If you’re tracking, it’s 22 Slimming World Syns or 18 WW Points.
Let’s talk about one of Greggs’ most straightforward but beloved bakes. The Cheese & Onion Bake has been quietly doing its thing on the shelf for years — no flashy marketing campaigns, no limited-edition hype, just a proper, cheesy, oniony pastry that does exactly what it says on the tin. I’ve had it more times than I can count, usually when I’m after something simple that won’t break the bank.
Here’s the thing though: a lot of people get confused about whether it’s vegan (it’s not), and the price varies quite a bit depending on where you buy it. So I’ve pulled together everything you need to know — current 2026 prices across all store types, the full nutritional breakdown, and whether it fits into common diet plans. Let’s get into it.
How much does a Cheese & Onion Bake cost at Greggs in 2026?
Greggs doesn’t do one flat price nationwide — they run a three-tier system based on location and operating costs. Here’s what you’ll actually pay in 2026:
| Store Type | Price | Where You’ll Find This |
|---|---|---|
| Standard (High Street) | £1.60 | Typical high-street and retail-park Greggs — the majority of the 2,759 UK outlets |
| City / London | £1.80 | City centres, major shopping centres, central London branches |
| Franchise / Airport | £2.15 | Airports, motorway services, large train stations |
The jump from standard to franchise pricing is about 34% — which sounds steep until you remember that airport rent and staffing costs are in a completely different league. Even at £2.15 though, it’s still cheaper than most airport food options.
If you’re grabbing a Cheese & Onion Bake with a hot drink, ask for the Savoury Bake & Hot Drink Deal — it starts from £3.35 and gets you any savoury bake plus any regular hot drink. Buying them separately would cost closer to £4.00–£4.50, so you’re saving at least 65p.
Calories and full nutrition breakdown
Each Cheese & Onion Bake weighs 141.4g and contains 436 kcal — that’s 22% of the reference intake for an average adult on a 2,000 kcal diet. Here’s the complete nutritional profile per portion:
| Nutrient | Amount | % of Reference Intake |
|---|---|---|
| Energy | 436 kcal (1,831 kJ) | 22% |
| Fat | 30g | 43% |
| — of which saturates | 16g | 80% |
| Carbohydrates | 33g | — |
| — of which sugars | 1.4g | 2% |
| Protein | 8.6g | — |
| Salt | 1.6g | 27% |
⚠️ Heads up on saturated fat: At 80% of your daily reference intake, the saturated fat content is the main nutritional consideration here. That’s not unusual for a puff-pastry bake, but it’s worth knowing if you’re watching your saturates across the day.
Compared to other savoury bakes, the Cheese & Onion sits toward the higher end calorie-wise. The Steak Bake (411 kcal) and Chicken Bake (420 kcal) are both slightly lighter, while the Vegan Sausage Roll is noticeably lower at 308 kcal.
Is the Greggs Cheese & Onion Bake vegan?
No, it’s not vegan. The Cheese & Onion Bake is vegetarian but contains dairy throughout — both in the cheese filling and in the pastry itself.
The filling uses a blend of cheeses including mature Cheddar, and the puff pastry contains milk-derived ingredients. If you’re following a vegan diet, this isn’t an option for you.
If you’re after a vegan savoury bake, your best bets are:
- Vegan Sausage Roll — 308 kcal, £1.35 standard
- Vegan Lattice (Steak-Free) — 372 kcal, £2.10 standard
Both are confirmed permanent menu items and available at most stores. Check our full vegan menu guide for the complete list.
Slimming World Syns and Weight Watchers Points
If you’re tracking on a diet plan, here’s where the Cheese & Onion Bake sits:
| Diet Plan | Value | Context |
|---|---|---|
| Slimming World | ~22 Syns | Calculated from Greggs’ 436 kcal using the standard 20 kcal per Syn guide |
| Weight Watchers (WW) | 18 Points | WW’s published Greggs guide (last updated Jan 2024) |
⚠️ Important note: Slimming World doesn’t officially publish Syn values for Greggs items — the 22 Syns figure is calculated using the standard public conversion of roughly 20 kcal per Syn. For WW, the 18 Points comes from WeightWatchers UK’s official Greggs guide, though it’s worth checking the app for the most current figure as recipes can change.
Both figures put the Cheese & Onion Bake as one of the higher-value items in the savoury bakes range. If you’re budgeting your daily allowance, it’s definitely a treat-food rather than an everyday pick.
What’s actually in a Greggs Cheese & Onion Bake?
Here’s the full ingredient list from Greggs’ official product page:
Ingredients: Fortified Wheat Flour (Wheat Flour, Calcium Carbonate, Iron, Niacin, Thiamin), Palm Oil, Cheese (20%) [Milk], Onion (7%), Water, Skimmed Milk Powder, Wheat Gluten, Cream Powder (Milk), Stabiliser (Xanthan Gum), Mustard Powder, Salt, Black Pepper, Parsley, Yeast.
The cheese blend includes mature Cheddar, which gives it that proper tangy kick. The onion content is 7% — enough to taste without overpowering the cheese. And yes, it’s freshly baked in shops every day, which is why it smells so good when you walk in.
Allergen information
The Greggs Cheese & Onion Bake contains the following allergens:
- Wheat (Gluten-containing cereal)
- 🥛 Milk (Dairy — from cheese and pastry)
- 🌻 Mustard
⚠️ Cross-contamination warning: Greggs stores are high-volume, shared baking environments with open preparation areas and shared ovens. While the Cheese & Onion Bake doesn’t contain nuts, sesame, or eggs as direct ingredients, there’s always a risk of cross-contamination. If you have a severe or life-threatening allergy, always speak to store staff directly and check Greggs’ official allergen guide before ordering.
How it compares to other Greggs bakes
Let’s put the Cheese & Onion Bake in context with the rest of the savoury bakes range — on both calories and price:
| Bake | Standard price | Calories | vs Cheese & Onion Bake |
|---|---|---|---|
| Cheese & Onion Bake | £1.60 | 436 kcal | — |
| Steak Bake | £1.85 | 411 kcal | 25p more, 25 kcal fewer |
| Chicken Bake | £1.85 | 420 kcal | 25p more, 16 kcal fewer |
| Sausage Roll | £1.30 | 348 kcal | 30p cheaper, 88 kcal fewer |
| Vegan Sausage Roll | £1.35 | 308 kcal | 25p cheaper, 128 kcal fewer |
So the Cheese & Onion Bake is actually the cheapest of the hot savoury bakes by a clear margin — both the Steak Bake and Chicken Bake cost 25p more, despite having fewer calories. If budget is your main concern rather than calorie count, it’s the better-value pick of the three.
Calories per portion. The Cheese & Onion Bake is the highest-calorie option in the core savoury bakes range — but also the cheapest of the three hot bakes.
My honest take: The Cheese & Onion Bake is proper comfort food — flaky pastry, generous cheese filling, and that classic Greggs bake texture. It’s not the lightest option on the menu, but it’s never pretended to be. If you’re after something simple, filling, and under £2 at a standard store, it’s a solid pick — and it’ll cost you 25p less than reaching for a Steak Bake or Chicken Bake instead. Just don’t expect it to be vegan, and maybe pair it with a side salad if you’re watching the calories.
