Crisps Buying Guide: Choosing Potato Crisps for Every UK Snacking Occasion

Whether you are filling lunchboxes, preparing party snacks or stocking the cupboard for everyday treats, choosing the right crisps involves more than picking a familiar flavour. Pack size, allergens, ingredients and serving format can make a noticeable difference to value and convenience.

Common crisps buying pitfalls to avoid

1. Assuming every multipack offers the same value

A large box may look economical, but check the number and weight of individual packs before comparing prices. A 20-pack of 25g bags provides 500g in total, while a six-pack of 25g bags contains 150g. Smaller packs may be more practical for portion control and lunchboxes, but a sharing bag can offer a different cost-per-100g calculation.

2. Treating dietary labels as a substitute for reading the ingredients

Terms such as vegetarian, vegan or baked do not automatically mean a product is suitable for every dietary requirement. Seasonings may contain milk, soya, wheat, barley or other allergens. Some crisps also carry a “may contain” statement because of the manufacturing environment.

Always check the ingredient list and allergen declaration on the packaging, particularly when buying international crisps or products containing flavour enhancers, sweeteners or seafood ingredients.

3. Choosing a flavour without considering the occasion

Strongly seasoned flavoured crisps may suit an evening snack or party platter but may not appeal to everyone in a family lunchbox. Sharing crisps are useful for entertaining, while individual crisp packs are easier to distribute at picnics, school lunches and office breaks. Consider whether you need classic British crisps, baked crisps, gourmet crisps or more adventurous international flavours.

Key specifications to check before buying crisps

Pack size and format

For individual snacking, look for clearly stated serving sizes such as 16g, 22g or 25g packs. Multipacks can reduce the need to portion a larger bag, while 100g to 150g bags are more suitable for sharing. A 400g bag may suit frequent household use, but it should be resealed properly after opening to help preserve texture.

Ingredients and allergen information

Potato crisps are commonly made with potatoes, vegetable oil and seasoning, but recipes vary considerably. Some products use wheat flour or potato starch rather than sliced potatoes. Check for:

  • Milk and cheese ingredients in cheese-flavoured crisps
  • Wheat, barley, oats or soya in seasonings and coatings
  • Crustaceans in prawn crackers or seafood-flavoured snacks
  • Sesame, celery, mustard or sulphites where listed
  • Sweeteners such as aspartame, including the required phenylalanine warning

For example, Morrisons Prawn Crackers contain prawns, while Lay’s Roasted Seaweed flavour contains wheat, soya, milk, crustaceans and sesame.

Nutrition and preparation style

Nutrition panels allow a more meaningful comparison between regular, baked and speciality snacks. The Walkers Oven Baked Cheese & Onion multipack lists 437 kcal and 13g of fat per 100g, while Walkers Ready Salted lists 519 kcal and 31g of fat per 100g. These figures describe the products as supplied and should not be interpreted as a health endorsement.

“Baked” describes the preparation method, not a guarantee that a snack is suitable for every diet. Compare salt, saturated fat, sugar and serving size as well as the cooking method.

Frequently asked questions about crisps

Which crisps are suitable for lunchboxes?

Choose sealed individual crisp packs, such as 22g to 25g multipack bags, when convenience and easy distribution matter. Check the allergen information before packing them for children or sharing with others.

Are baked crisps lower in fat?

Some baked crisps contain less fat per 100g than comparable regular crisps, but this varies by product. Compare the nutrition panels directly rather than relying only on the word “baked”.

How should opened crisps be stored?

Keep unopened crisps in a cool, dry place. Once opened, consume them promptly or reseal the bag tightly. Moisture can reduce the crisp texture, particularly in sharing crisps and prawn crackers.
