Calorie-aware weeknight diners
If your dinner needs to stay under 500 kcal, look for a figure covering the full meal or the amount you will actually eat, not just 100g.
Who is this for?
Shoppers short on preparation time
A meal designed for cooking from frozen may suit an evening when you do not want to prepare a recipe. Check its appliance instructions, including any stirring or standing steps, before choosing it.
Vegetarian or vegan shoppers
Plant-based frozen bowls are one format to consider. Check the dietary statement and allergens on the individual pack rather than assuming every dish in a range meets your requirements.
What should you check?
Start with the calories for the amount you will eat, then compare meals that fit your cooking time and dietary requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Meal calories | Find kcal per pack or stated portion. Check the pack weight and servings, then include any sides you plan to eat. The NHS notes that a manufacturer's portion may differ from yours. | I want the whole dinner I serve to stay under 500 kcal, not just a 100g quantity. |
| Cooking method | Check whether the meal cooks from frozen in your microwave or oven. Read the appliance setting and any stirring and standing instructions on the pack. | On a busy evening, I need a method that fits the equipment and time I have. |
| Dietary suitability | Read the individual product's ingredients, allergen information and dietary statement. Check the physical pack before cooking, as M&S advises that product information can change. | A vegan label or familiar range name is not enough for me if the individual meal does not meet my dietary requirements. |
| Other nutrition | Compare declared salt, saturated fat, fibre and protein for the same serving basis, alongside kcal. Read any traffic-light labelling against the product's stated portion. | Once a meal meets my calorie limit, I still want to see how its other nutrition figures compare. |
Common buying mistakes
-
Treating kcal per 100g as the dinner total
The full tray or an added side may take your dinner above 500 kcal even when the per-100g figure looks suitable.
Use the kcal for the pack or your actual portion, and include everything you intend to serve. The NHS cautions that stated portion sizes may differ from the amount eaten.
-
Checking calories but nothing else
Meals with similar calorie totals can have different nutrition profiles. Action on Salt & Sugar's 2025 review of 1,511 chilled and frozen ready meals from 11 major retailers classified 56% as high in salt, 42% as high in saturated fat and 71% as low in fibre.
Compare the declared salt, saturated fat, fibre and protein figures for the portion you will eat.
-
Building dinner plans around a listing
A product page does not guarantee that a particular meal will be available when you shop. Iceland Foods marked some of its Heinz frozen-bowl listings as unavailable.
Check the current listing and have another meal format in mind before relying on a particular bowl for the week.
-
Skipping the heating directions
The cooking method and appliance setting matter when deciding whether a frozen meal fits your evening routine.
Follow the individual pack's instructions for heating, stirring and standing rather than using a time from another product.

Questions about frozen meals
Does under 500 kcal refer to the figure per 100g?
No. For this dinner target, use the kcal for the full pack or the portion you will actually eat. The NHS notes that labels may show kcal per 100g or per portion, and that the manufacturer's portion size may differ from yours.
Is a meal under 500 kcal enough to make the choice?
No. Compare salt, saturated fat, fibre and protein as well as kcal. In its 2025 review of 1,511 chilled and frozen ready meals from 11 major retailers, Action on Salt & Sugar classified 56% as high in salt, 42% as high in saturated fat and 71% as low in fibre.
How should I cook a frozen ready meal?
Follow that product's pack instructions for the appliance setting, cooking time and any stirring or standing steps. Check that the stated method works with the equipment you have before buying.
Can I use an online listing to check allergens?
Use the listing to narrow your choices, then read the physical pack before cooking or eating. M&S advises that ingredients, dietary information, nutrition and allergen details can change.
