Students stocking a shared or small freezer
Think about how two bags will fit alongside other food and whether their combined quantity suits the dinners you plan to make. Pack weight matters as much as the number of bags.
Who is this choice for?
Students cooking with an air fryer
Look for directions for the exact chips and check the stated appliance capacity, wattage and portion. In a 2022 survey of more than 2,000 UK adults by Leatherhead Food Research, 73% of the surveyed air-fryer owners said they cooked chips in theirs; that figure does not describe students specifically.
Shoppers checking ingredients
Check the current pack when sharing food or buying for a dietary requirement. McCain Home Chips Straight Cut lists wheat, while Aunt Bessie's describes its Homestyle Chips as made with gluten-free vegetarian ingredients. Neither statement applies to every product from those brands.
What should you check?
Start with the space and quantity you need, then check whether each bag has directions for the appliance you will actually use.
| Priority | What to check | Your needs |
|---|---|---|
| Freezer quantity | Check each bag's weight and whether both will fit. Two 1.5kg bags make 3kg; a smaller second bag gives you a different total. | I want enough chips for several dinners without taking up space needed for other food. |
| Cooking method | Match the pack's directions to your oven or air fryer. Tesco bases its Hearty Food Co air-fryer directions on a minimum 3.8L appliance; ASDA specifies a minimum 4L appliance and a 125g portion for its Straight Cut Chips. | If I mainly use an air fryer, I need instructions that fit its basket and the quantity I cook at once. |
| Cooking time | Check the portion and appliance behind any stated time. McCain gives 7 minutes at 2000W, 8 minutes at 1700W and 10 minutes at 1400W for its Air Fryer Deep Ridge Crinkle Cut Chips. | On a short evening, a separately packed air-fryer option may be useful, but I cannot apply one product's timing to another. |
| Ingredients and allergens | Read both current labels, including coating ingredients and precautionary allergen statements. A shared brand or chip shape does not establish that two products have the same ingredients. | When someone sharing dinner has a dietary requirement, I need to check each bag rather than assume the pair is interchangeable. |
What can catch you out?
-
Assuming all frozen chips cook at the same speed
Stated air-fryer times depend on the product, appliance and portion. McCain's Air Fryer Deep Ridge timings vary by wattage, while ASDA's Straight Cut Chips instructions specify a minimum basket capacity and a 125g portion.
Use the directions on the exact pack and check whether their appliance and portion assumptions match yours.
-
Judging allergens by how the chips look
A coating may contain ingredients that are not apparent from the chip shape. ASDA Groceries lists wheat in McCain Home Chips Straight Cut.
For an allergy or dietary requirement, read the current label on each bag before use.
-
Filling the air-fryer basket for one large batch
Pack timings may be based on a much smaller portion than the bag contains. ASDA's Straight Cut Chips air-fryer directions use a 125g portion and call for a single layer.
Follow the pack's loading and turning directions; plan for separate batches if the portion will not fit as instructed.
Batch cooking takes more time than preparing the stated portion once.

Questions about choosing and storing chips
Should both bags be the same frozen chips?
Choose two of the same bag if its quantity, ingredients and cooking method work for your repeat dinners. A different second bag makes sense when it serves a distinct need, such as directions for the air fryer you use or a particular dietary requirement. Check that both bags fit your freezer.
Can oven chips go in an air fryer?
Use air-fryer directions for the exact product rather than transferring its oven settings. Tesco Hearty Food Co Straight Cut Chips and ASDA Straight Cut Chips both have stated air-fryer instructions, but those instructions use different appliance-capacity and portion assumptions.
How should I store frozen chips after opening the bag?
Keep them frozen and follow the storage directions on the exact pack. M&S Straight Cut Chips and McCain Home Chips Straight Cut specify storage at -18°C or below and say not to refreeze after thawing.
Do frozen chips all have the same allergens?
No. ASDA Straight Cut Chips list potatoes, sunflower oil and dextrose, whereas McCain Home Chips Straight Cut lists wheat-containing coating ingredients. Aunt Bessie's describes its Homestyle Chips as made with gluten-free vegetarian ingredients. Read each current pack when an allergen or dietary requirement affects the choice.
