For a one-person winter meal, choose an individually portioned steam bag if you have a microwave and want a side dish without measuring it out. Choose a loose pack if you want to vary the amount going into a soup, stew or pie; either way, check the ingredients and follow the cooking instructions on the exact pack.
An individual steam bag gives you a separate vegetable side for a jacket potato, pie or ready meal without weighing vegetables from a larger pack. You need a microwave and should use the selected pack’s cooking instructions.
A loose pack lets you choose different amounts for soups, stews and pies. If you are using the NHS 5 A Day guide, 80g of frozen vegetables counts as one portion.
Compare the space a pack will take with the number of meals you expect to make from it. Separately packed bags offer fixed amounts; a loose bag lets you take out only the quantity needed for a recipe.
Start with how you will use the vegetables: as a separate side for one meal or as an ingredient whose quantity you want to adjust.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Compare total pack weight with the number and weight of any individual bags. The NHS counts 80g of frozen vegetables as one 5 A Day portion; that is not necessarily the weight of a steam bag. | I want a separate side without measuring it out, or a smaller amount that I can take from a loose pack. |
| Cooking method | Check whether the pack calls for microwave cooking or another method, including wattage, standing time and bag-handling instructions. Follow the directions for the selected product. | For a quick side, I have a microwave and can follow the steam-bag directions. For a cooked dish, I need vegetables that fit its preparation method. |
| Meal use | Choose fixed bags for separate portions or a loose pack when the amount needs to change between recipes. Check that the pack fits your freezer space. | A side for a single pie is different from vegetables going into several portions of soup or stew. |
| Ingredients | Read the exact pack’s ingredient, allergen and nutrition information rather than assuming every vegetable mix is plain. Check whether the product is raw and requires cooking. | I may want plain vegetables for a flexible ingredient, or a particular prepared mix for a separate side. |
The NHS uses 80g as its guide to one 5 A Day portion of frozen vegetables. Four-bag, 540g Birds Eye packs listed by Sainsbury’s work out at 135g per bag, while Waitrose lists some steamers at 160g per bag.
Check the pack weight and bag count. Decide whether a whole bag suits your meal or whether you would rather measure out vegetables from a loose pack.
Frozen vegetable ranges can include prepared or flavoured products, so the range name alone does not establish the ingredients of a particular pack.
Check the ingredient, allergen and nutrition information on the exact product, especially when you need plain vegetables for a soup or pie.

No. The NHS excludes potatoes and some other starchy foods from 5 A Day. If a jacket potato is the main part of your meal and 5 A Day is your aim, count a separate qualifying vegetable portion instead.
