A humble sheet of pastry could carry your next get‑together.
Across Britain, home cooks are rescuing neglected puff pastry and turning it into warm, flaky swirls that feel pub‑snack posh. The formula is simple: blue cheese for depth, walnuts for snap, and an oven hot enough to bronze the edges before the first guests knock.
Why this speedy bake is trending
Many households face a familiar scene: a single pastry round left from a weekend pie, a nub of blue cheese near the back of the fridge, and a handful of nuts. Instead of wasting them, people are baking bite‑size rolls that sit neatly beside a glass of red, a pint, or a pot of tea.
The timing suits the season. Evenings draw in. Bonfire Night plans loom. Football gatherings return. A tray of warm, buttery spirals can appear in 20 minutes. No mixer. No faff. Just a sharp knife and a hot oven.
Ready in 20 minutes at 200°C. Slice to 1 cm. Use about 100 g blue cheese and 50 g walnuts for one 260 g pastry sheet.
The method at a glance
Gather simple kit and ingredients
- 1 sheet puff pastry, all‑butter, about 260 g
- 100 g blue cheese (Fourme d’Ambert for mildness, Roquefort for bite, or a British Stilton)
- 50 g walnut halves, roughly chopped
- 1 egg yolk mixed with 1 tbsp milk for gloss
- Black pepper, optional
- Baking paper and a sharp knife
Shape, slice and bake
Bring the pastry out of the fridge for five minutes so it unrolls without cracking. Lay it on baking paper. Lightly pass a rolling pin over the surface to even thick spots without crushing the layers.
Crumble the blue cheese into a thin, even layer, leaving a 1 cm border at one short edge. Scatter the walnuts over the top. Add a turn of pepper if you like more fragrance.
Roll up from the filled short edge to the border, keeping the log snug yet gentle. Brush the bare border with cold water and press to seal. Trim the ends if messy. Slice into 1 cm rounds with a clean, sharp blade, wiping between cuts.
Space the spirals on a lined tray. Brush with the egg‑milk mix for a rich sheen. Bake at 200°C (180°C fan) for about 20 minutes until crisp, layered and golden, with a creamy centre.
Don’t overload the filling. Seal the seam with water. Wipe the knife after each cut for a neat spiral.
Cost, time and yield
| Item | Amount | Typical UK price | Note |

From a single sheet you can plate 16 to 20 pieces, enough for four to six people with drinks or as a side to soup.
Flavour that punches above its weight
Blue cheese does the heavy lifting by melting into the pastry, seasoning every layer. If you prefer mild notes, pick a creamy Fourme d’Ambert or a young Stilton. For more tang, go with Roquefort. Walnuts bring balance, with woody sweetness and gentle crunch that survives the bake.
Toast the walnuts for five minutes in a dry pan if they taste flat. The aroma deepens, the texture sharpens.
Pairings and smart swaps
Sweet‑savoury contrasts that work
- A teaspoon of runny honey brushed on the hot swirls
- Fig chutney or onion relish on the side
- Thin pear slices tucked into the roll before baking
- Poppy seeds sprinkled over the glaze for speckled tops
- Swap walnuts for hazelnuts or pistachios if preferred
For a cheese board alternative, set the swirls with grapes, whole walnuts and a few rosemary sprigs on a wooden board. It looks generous without extra effort.
Make‑ahead, freezing and reheating
Bake, cool and store in an airtight tin for 24 hours. Reheat at 180°C for three to four minutes to revive the flake and flow. Or freeze the raw slices: lay flat on a tray until solid, then bag. Bake from frozen at 200°C for about 22 minutes until the pastry is fully puffed and the centre bubbles gently.
Nutrition and safety notes
- Allergens: contains gluten, milk and tree nuts. Check labels if serving guests.
- Blue cheese is salty. If salt intake matters to you, skip extra seasoning and serve with fresh fruit.
- Pregnancy guidance varies by cheese style. Cook until steaming hot throughout and use a firm, pasteurised blue to reduce risk.
- Walnut sensitivity is common. Offer a nut‑free tray baked with pumpkin seeds for mixed groups.
Where this fits in your week
Serve with a velvety broccoli soup on a Monday, or pass a tray during a Saturday match. Pack two or three for a lunchbox with crisp apples. They also make a quick nibble before a late supper when friends arrive unannounced.
From waste to value
Britain throws away millions of tonnes of edible food each year, with households responsible for the majority. A single leftover pastry sheet might look trivial, yet repeated small saves add up to real money. For many families, that figure runs to several hundred pounds annually, mostly from forgotten or half‑used items.
One pastry sheet. One nub of cheese. One handful of nuts. A warm tray in 20 minutes—and nothing wasted.
Keeping a short “use‑it‑soon” list on the fridge door helps. So does a standing plan for pastry offcuts: swirls, cheese straws, palmiers or jam pinwheels. The habit reduces bin trips and gives you a ready answer when hunger strikes.
Beyond blue and walnut
Three fast variations to keep on rotation
- Goat’s cheese, walnut and a thread of honey for a tangy, mellow finish
- Feta and pistachio with lemon zest and chilli flakes for a sharper edge
- Brie and chopped dried apricots for a rich, fruity bite
Use the same 1 cm slice rule and the same temperature. The technique remains identical, so you can adapt to whatever the fridge yields.
Practical extras you will actually use
Knife test: when the blue bubbles gently and the pastry layers separate cleanly, you are done. Greaseproof paper prevents sticking and keeps trays clean. If your oven runs hot, start checking at 16 minutes.
Serving trick: for a party, bake two trays staggered by eight minutes. The first tray hits the table while the second finishes. Guests get hot swirls without waiting, and you avoid crowding the oven.
