Households serving regular Sunday roasts
If chips appear at roasts and other meals, one bag can cover everyday quantities while a second offers a different cut for the roast. Check that both will be used before giving them freezer space.
Who is this for?
Households with limited freezer space
Two large bags may leave too little room for other frozen roast components. Compare pack sizes with the space available in your freezer drawers before choosing a pair.
Households with different dietary requirements
Ingredients vary by product: the McCain and M&S product information described below includes both simpler-ingredient chips and products containing wheat or beef fat. Choose by the exact pack, not by the assumption that all frozen chips are alike.
What matters when choosing two bags?
Give each bag a job: decide how much you need for repeat meals, then whether a different cut is useful for the roast. Check space, cooking instructions and ingredients for both.
| Priority | What to check | Your needs |
|---|---|---|
| Freezer space | Compare both bag sizes with the drawer space available. Leave room for any other frozen parts of the roast. | I need chips ready for several meals, but not two bags that crowd out the rest of dinner. |
| Quantity | Check each pack’s weight and whether you expect to use it at roasts, other meals or both. Retailer listings cited by Sainsbury’s and Tesco Groceries include bags from 1.2 kg to 2.1 kg; M&S describes a 600 g Gastropub pack. | For regular family meals, I want enough in the everyday bag; a smaller second bag may be sufficient when it has a separate role. |
| Cut and cooking | Choose between straight-cut, chunky and homestyle products by the meal you intend to serve. Read the instructions for your appliance and allow for oven space alongside the roast. | Will the second cut add something I want at a Sunday roast, and can I cook it alongside the other dishes? |
| Ingredients | Check the current ingredient and allergen panel for each exact variant. McCain UK lists wheat in Home Chips Straight Cut, while M&S lists beef fat in its Gastropub Triple Cooked Chips. | If guests avoid wheat or animal ingredients, I need a bag that suits them rather than assuming every potato product does. |
Common buying mistakes
-
Putting two large bags in the basket without checking freezer space
The bags may take up space needed for other frozen roast components.
Check the available drawer space first. If it is limited, consider one everyday bag and a smaller second bag rather than two large packs.
-
Assuming all frozen chips have the same ingredients
McCain UK lists wheat in Home Chips Straight Cut; M&S lists beef fat in its Gastropub Triple Cooked Chips. Neither detail can be assumed for every product in those brands’ ranges.
Read the ingredient and allergen panel on each pack, particularly when serving someone with an allergy or a vegetarian, vegan or gluten-free requirement.
-
Relying on a small roast-style bag for every meal
A 600 g pack holds less than the 1.2 kg and larger packs shown in retailer listings, which matters if several people will eat chips regularly.
Match pack weights to the number of meals planned. A smaller bag can serve a separate roast role while a larger bag covers more frequent use.
-
Giving every bag the same oven time
Cooking directions vary by product. Aunt Bessie’s gives a 20–25 minute oven time for its 1.3 kg Homestyle Chips and advises turning them during cooking.
Follow the directions on the chosen pack and plan oven space around the other roast dishes.
Brands and their frozen-chip ranges
These range examples show why the exact variant matters; they do not establish that every product from a brand has the same ingredients or cooking directions.
McCain
McCain UK describes Home Chips and Naked Oven Chips with different ingredient profiles, so the choice depends on the variant as well as the cut.
- McCain UK says Naked Oven Chips Straight Cut contain potatoes and sunflower oil and are vegan and gluten-free.
- McCain UK lists wheat in the batter of Home Chips Straight Cut. Do not apply the Naked Oven Chips description to coated Home Chips.
Aunt Bessie’s
Its 1.3 kg Homestyle Chips offer a roast-side option with published oven instructions.
- Aunt Bessie’s describes this Homestyle variant as vegetarian and gluten-free.
- Its stated 20–25 minute oven time needs to fit around the other dishes; check the pack for full cooking directions.
Tesco
Tesco Groceries lists 1.5 kg own-label chips as well as a 1.2 kg Finest British Chunky Oven Chips option.
- The listed pack weights offer different quantities for an everyday bag and a second roast-style bag.
- Check the chosen product’s own label for ingredients and cooking instructions; range listings do not establish suitability across all Tesco chips.
Sainsbury’s
Sainsbury’s lists branded frozen chips alongside its 1.2 kg Taste the Difference Chunky Chips.
- The listing includes different cuts and pack sizes that could fill separate everyday and roast roles.
- Check the exact product page and pack for ingredients, allergens and preparation rather than applying range-level information to one bag.
M&S
M&S describes its Gastropub Triple Cooked Chips as a chunky, beef-fat-coated option.
- The stated 600 g pack offers a different format from the larger everyday bags in the retailer listings.
- M&S lists beef fat in this product, so it is not suitable for vegetarian or vegan diners. M&S also states that it is raw and must be cooked.

Questions about stocking frozen chips
Which two types of frozen chips should I keep for Sunday roasts?
If chips feature in regular meals, an everyday bag plus a chunky or homestyle bag gives each a distinct role. Choose pack sizes that fit your freezer and the number of people you serve; one bag may be more practical if space is limited.
Should I choose the biggest bags?
Choose large bags only if they fit alongside your other frozen food and you expect to use them. Check the pack weights and available drawer space before buying two.
Are frozen chips always vegetarian, vegan or gluten-free?
No; suitability depends on the exact variant. McCain UK describes Naked Oven Chips Straight Cut as vegan and gluten-free, Aunt Bessie’s describes its Homestyle Chips as vegetarian and gluten-free, and M&S lists beef fat in its Gastropub Triple Cooked Chips. Check the current pack before serving someone with a dietary restriction or allergy.
Do I need to thaw frozen chips before cooking them?
Follow the instructions for the bag you choose. McCain UK’s Home Chips Straight Cut directions and Aunt Bessie’s oven-chip guidance call for cooking from frozen; do not assume every product uses the same time or method.
How should I store a bag after opening it?
Follow that product’s storage instructions and keep the chips frozen as directed. M&S specifies −18°C for its Gastropub Triple Cooked Chips and says not to refreeze them after thawing; Aunt Bessie’s gives a no-refreezing-after-defrosting instruction for its Homestyle Chips.
