Choose a clearly labelled sourdough croissant when sourdough is a genuine requirement and you can confirm the ingredients, allergen information and collection or delivery timing. For a larger, less specialised spread, all-butter multipacks or frozen bake-at-home croissants can be more practical, but frozen pastries need freezer space, oven capacity and clear allergen details for guests.
You are planning a small or curated street-party pastry table and want a croissant sold specifically as sourdough, rather than a standard croissant from a retailer that also sells sourdough bread. Hunnypot Cottage Bakery and Robert Andrew Low-Carb Sourdough list specialist sourdough-croissant options.
You need familiar, portionable croissants in multipacks and can accept conventional all-butter croissants when specialist sourdough options are not practical at the quantity required. M&S, Tesco and Waitrose list conventional croissant ranges.
You are supplying food to other people and need to retain packaging or obtain accurate ingredient and allergen details before guests serve themselves. Food Standards Agency guidance covers allergen information for food supplied at community events and by food businesses.
Choose it when: Sourdough is a firm requirement and you can confirm the exact product, ingredients, quantity and collection or delivery window.
Consider: A sourdough label does not establish that a croissant is gluten-free, dairy-free or suitable for every guest.
Choose it when: You need familiar, portionable multipacks and do not specifically require sourdough.
Consider: A retailer selling sourdough loaves does not mean its croissants are sourdough.
Choose it when: You have dependable freezer space, an oven and time to bake close to serving.
Consider: This route depends on cold storage, oven throughput and following the pack instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Sourdough identity | Check that the exact croissant title and product description say “sourdough croissant”. Read the ingredient list and bakery description rather than relying on a retailer’s separate sourdough-bread range. | I want the requested sourdough product, not a conventional all-butter substitute with a similar-looking bakery label. |
| Serving timing | For frozen pastries, confirm freezer storage needs, cooking instructions and oven batches. Compare pack counts when working out how many pastries to put out at a time. | I need croissants that can be served at the right time without overloading the freezer or oven just before the party. |
| Allergen information | Keep the original packaging or an accurate ingredient and allergen record at the serving table. Check each exact product, especially filled or almond-topped pastries. | I want guests to be able to identify ingredients they need to avoid before choosing a pastry. |
M&S, Tesco and Waitrose list conventional croissants while sourdough appears separately within bread ranges or other bakery products. That distinction matters if sourdough has been specifically requested.
Read the exact croissant title and product description. If the croissant itself is not labelled sourdough, treat it as a conventional alternative.
Croissants commonly contain cereals containing gluten, milk and egg, and filled varieties can add nuts or other allergens. Guests need usable information before choosing food.
Keep product packaging or a clear ingredient and allergen record with the serving table. If you prepare or repackage food as a registered business, follow the applicable allergen-information rules.
Frozen pastries need continuous frozen storage and enough oven time close to serving. Pret frozen croissant listings specify frozen storage and cooking before serving.
Count trays and oven batches before ordering, check delivery availability for the event postcode and follow the exact pack storage and cooking instructions.

For England, Northern Ireland and Wales, the Food Standards Agency says a person selling or supplying food may be considered a food business and may need to register, although a local authority may consider registration unnecessary for very limited and infrequent activity. Food Standards Scotland says occasional handling, preparation, storage or serving is unlikely to require registration, while regular and organised provision may require it. Ask the relevant local authority if the event’s status is unclear.
Keep the original packaging with prepacked croissants where possible so guests can check ingredients. For registered food businesses, Food Standards Agency guidance requires allergen information for prepacked, PPDS and non-prepacked food under the applicable rules. A product described as vegan is not automatically free from gluten or other allergens.
Yes, if you can keep them frozen and bake them according to their instructions. Pret’s all-butter frozen croissants state storage at -18°C or cooler, say not to defrost or refreeze once thawed, and state a 20-minute bake from frozen. Check the exact pack because cooking guidance and availability vary by product.
No. M&S, Tesco and Waitrose list conventional croissants alongside separate sourdough-bread ranges or products. Choose a croissant as sourdough only when the exact croissant product itself is labelled and documented that way.
