If you have a food allergy, first choose a croissant whose current allergen information matches what you need to avoid; only then consider whether you can fill it. A gluten-free croissant may still contain egg, milk or soya, while a plant-based croissant may contain wheat and carry a milk warning. For a generously filled snack, the preparation instructions and how easy the croissant is to handle after baking are more useful than the description ‘thickly sliced’.
Look for a product explicitly labelled gluten-free, and check the other allergens too. According to the Netherlands Nutrition Centre, even a small amount of gluten, such as a bread crumb, can cause symptoms in people with coeliac disease.
If you are allergic to, for example, milk, egg, soya, nuts or sesame, ‘plant-based’ or ‘gluten-free’ doesn’t tell you enough. Check the ingredients and warnings on the packaging of the specific croissant.
If you want to enjoy a filled croissant as a snack, choose one based on its allergen information first. Then check the preparation instructions and whether you can slice the baked croissant open without it falling apart.
Start with the allergen you need to avoid and check the information on the current packaging. Portion size and preparation method only become relevant for a filled snack once you’ve made the right choice on allergens.
| What to consider | What to check before buying | Who it matters to |
|---|---|---|
| Gluten and wheat | Check the gluten-free label and the full allergen information for the variant you’ve chosen. | If I need to avoid gluten or wheat, I don’t want to judge a croissant by its appearance. For around 40% of consumers making this choice, avoiding these ingredients is the top priority. |
| Other allergens | Check which allergens are listed as ingredients and what warnings about possible cross-contamination appear on the packaging. | If I’m allergic to, for example, milk or egg, I need information about that specific product, even if it’s labelled plant-based or gluten-free. Around 40% of consumers put this check first. |
| Filling after baking | Check the preparation instructions and see whether the croissant can be sliced open after baking; use clean utensils to prevent cross-contamination. | Once I know the allergen profile is suitable, I want to be able to fill a croissant without it falling apart. Around 20% of consumers put this practical consideration first. |
Jumbo’s product information for Croissant Plantaardig lists wheat and gluten, and warns that the product may contain milk. So the name alone doesn’t answer your allergy question.
Read the ingredients and allergen information on the current packaging before choosing this variant.
According to Jumbo, Consenza gluten-free croissants contain egg, milk and soya. A gluten-free label doesn’t mean that other allergens are absent.
Check for all the other allergens you need to avoid, including warnings about possible cross-contamination.
If you’re buying a croissant from a bakery or fresh food counter, you may not have a pack with an ingredients list to hand.
Before buying, ask specifically about the allergens that matter to you and any information about possible cross-contamination.
According to the Netherlands Nutrition Centre, bakers aren’t required to use iodised baking salt. Nor does the word ‘croissant’ tell you how firm it will be after baking.
If you have questions about baking salt, check the ingredients list or ask the seller when buying an unpackaged product. Only assess how easy it is to handle for filling once you’ve confirmed its allergen profile is suitable.
AH offers both regular and explicitly gluten-free croissants. Allergen information varies by product.
Jumbo Croissant Plantaardig shows why a plant-based product name needs to be considered separately from its allergen profile.
Consenza has a gluten-free croissant variant, but you’ll need to check its other allergens too.
Albert Heijn describes Schär Croissant à la Française as a gluten-free croissant for people with gluten intolerance.
Délifrance butter croissants are a regular option to compare by ingredients with gluten-free or plant-based croissants.
For a pre-packed croissant, the allergen information is on the label. The Netherlands Food and Consumer Product Safety Authority provides guidance on labelling for 14 allergens. If the croissant is unpackaged, ask for its allergen information before buying.
No. Gluten-free doesn’t mean a croissant is free from other allergens. According to Jumbo, Consenza gluten-free croissants contain egg, milk and soya; Albert Heijn says AH gluten-free croissants may contain egg. So read the full allergen information on the packaging you’ve chosen.
No. A plant-based product name doesn’t rule out a milk warning. Jumbo states that Croissant Plantaardig may contain milk. Check the current packaging for both ingredients and warnings about possible cross-contamination.
It indicates a possible risk that an allergen listed in the warning could accidentally get into the product. According to the Netherlands Food and Consumer Product Safety Authority, new rules have applied in the Netherlands since 1 January 2026 on how and when businesses warn about this on labels. Check the warning on the current packaging in relation to the allergen you need to avoid.
Use clean hands, a clean knife, a clean chopping board and clean utensils to prevent cross-contamination. This is particularly important if you have coeliac disease: according to the Netherlands Nutrition Centre, even a stray bread crumb can cause symptoms.
