Weekly shoppers choosing single meals
If you are stocking the freezer for several dinners, check the calories for each prepared pack and how many servings it contains. A figure per 100g may not describe the amount you plan to eat.
Who is this for?
Shoppers comparing protein as well as calories
If protein matters to your choice, compare grams per prepared pack alongside calories and salt. Product information from Tesco Groceries and Asda Groceries gives examples with 23g to 25.5g protein per microwaved pack; those examples also have medium salt labels.
Shoppers checking ingredients and allergens
Check the exact meal’s current ingredient and allergen information before adding several different recipes to a weekly shop. Frozen meals in this selection include ingredients or warnings involving milk, barley, wheat and soya.
What should you check?
Start with the calories for the amount you will eat, then compare the other label details that matter to your choice and the way you will cook each meal.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-meal calories | Find kcal for the prepared pack or stated serving. Check the serving count and calculate the amount you intend to eat if it differs. | I want each meal I eat to stay under 500 kcal, not just each 100g of it. I will count any sides or additions separately. |
| Salt and saturates | Compare grams and any traffic-light labels on a consistent per-pack or per-serving basis. Tesco Groceries and Asda Groceries list under-500-kcal examples with medium salt labels. | A meal can meet my calorie limit while having a different salt or saturated-fat profile from another option. |
| Protein | Read protein grams for the prepared pack, using the same portion basis as the calorie figure. Tesco Groceries and Asda Groceries list examples with 23g to 25.5g per microwaved pack. | If I am comparing meals for lunch or dinner, I want to see how their stated protein figures differ without treating calories alone as the whole comparison. |
| Allergens | Read the current ingredient list and allergen statement for the exact recipe, including any may-contain warning. | I need to rule out ingredients that conflict with my requirements, regardless of the meal’s calorie figure or range name. |
| Cooking and storage | Check whether the meal uses a microwave or oven, its appliance-specific instructions and its frozen-storage directions. | For a week’s worth of meals, I want cooking methods and timings that fit the evenings when I plan to use them. |
Common buying mistakes
-
Assuming an under-500-calorie shelf guarantees every pack qualifies
Tesco Groceries shows The Gym Kitchen Chicken Katsu Curry 550g in its under-500-calorie category, while its product information states 580 kcal per microwaved pack.
Check the prepared-pack calories on the exact product before adding it to your weekly plan.
-
Using a per-100g figure for a whole tray
The portion used on a nutrition label may differ from the amount you intend to eat.
For a meal you will eat in full, use its prepared-pack figure; use per-100g figures when making a like-for-like comparison between products.
-
Stopping at the calorie figure
Tesco Groceries and Asda Groceries list frozen meals below 500 kcal per prepared pack with medium salt labels. Ingredients and allergens also differ between recipes.
Compare the current nutrient label and ingredient list after confirming the calories for your portion.
-
Stocking up before checking cooking instructions
Frozen meals can require different appliances, timings and preparation steps, which matters when planning several dinners.
Check each pack’s cooking and storage instructions before deciding how many meals to buy.
A meal you cannot prepare with the equipment or time available may go unused.
Retailer ranges to explore
A frozen-meal range can help you find candidates for the weekly shop, but the individual pack determines whether a meal meets your calorie limit.
Tesco
Tesco Groceries has a frozen category labelled “Under 500cal Meals” and product pages with prepared-pack nutrition.
- Its Chicken Tikka Masala 350g is listed at 353 kcal and 23.4g protein per microwaved pack.
- Check each item separately: a Chicken Katsu Curry 550g shown in the category is listed at 580 kcal per microwaved pack.
Asda
Asda Groceries has a frozen ready-meal category and individual product nutrition information.
- Its Protein Piri Piri Chicken with Spicy Rice 400g is listed at 332 kcal and 23g protein per microwaved pack.
- That meal is also listed with 1.3g salt, labelled medium; check its current ingredients and allergens.
M&S
M&S lists individual frozen dishes alongside larger meals and dishes suited to sharing.
- The range shown by Marks & Spencer includes 270g and 400g dishes.
- A pack’s weight or place in the range does not establish its calories per intended serving; check the exact label.
Waitrose
Waitrose & Partners lists frozen meals including 400g chilli con carne with rice and chicken tikka masala with rice.
- Named one-pack meals give you specific recipes to investigate for the weekly shop.
- Check each product’s calories and serving basis rather than treating a 400g pack as an under-500-kcal meal.
Sainsbury’s
Sainsbury’s lists frozen ready meals for one, including several 400g dishes.
- The range includes different recipes in a meal-for-one format.
- Confirm calories for the exact pack; “for one” and pack weight do not establish the calorie figure.
Iceland
Iceland Foods has frozen ready-meal and value-meal ranges that can be browsed when planning freezer meals.
- Separate range pages provide routes to finding frozen meal options.
- Use the selected meal’s nutrition table and serving size to assess the under-500-kcal requirement.
Joybuy product options
These Joybuy options cover a frozen chicken tikka meal and chicken soup dumplings. If you serve the dumplings with other food, count the whole meal you intend to eat against your 500 kcal limit.

Itsu Chicken Soup Dumplings 6Packs

Questions about choosing and cooking
Is an under-500-kcal figure enough to compare frozen meals?
No. First confirm that the figure covers the prepared amount you will eat, then compare other label information such as saturates and salt. Tesco Groceries lists a 327 kcal frozen meal with 1.5g salt, labelled medium.
Should I use calories per 100g or per pack?
If you will eat the whole one-person pack, use its prepared-pack calories to check your 500 kcal limit. A per-100g figure helps you compare products on the same weight basis, but check the stated servings before using it as your meal total.
How should I cook a frozen ready meal?
Follow the instructions for the exact meal and appliance, including any directions to stir or allow standing time. Cooking times for one product or microwave wattage should not be transferred to another.
Can I refreeze a ready meal after it has thawed?
Do not assume that you can: check the meal’s defrosting and refreezing instructions. GOV.UK advises checking packet instructions for freezing suitability and says a freezer should be around −18°C.
What should I check if I have a food allergy or intolerance?
Read the current ingredients, allergen statement and any may-contain warning for the exact meal before buying or cooking it. GOV.UK and the Food Standards Agency explain that UK food businesses must provide information when any of the specified allergens are ingredients; the calorie figure does not answer an allergen question.
