Batch cooks
If you make soups, stews, casseroles or pies throughout winter, a loose bag lets you take the amount each dish needs and add your own seasoning or aromatics.
Who might choose each format?
Cooks looking to cut preparation
A casserole or soffritto mix can provide vegetables that are already chopped for a soup, stew or sauce. Check the blend before using it in place of your usual ingredients: soffritto can contain celery.
Households making quick sides
Microwave steam bags provide portioned vegetables to cook alongside a winter main meal. You will need a microwave and must follow the instructions for the particular bag.
What should you check before choosing?
Start with the dish: a vegetable base for a stew calls for a different blend from a side dish cooked just before serving.
| Priority | What to check | Your needs |
|---|---|---|
| Recipe fit | Read which vegetables are in the bag and whether they are chopped for the intended dish. A peas-only bag and a soffritto blend serve different purposes. | For a stew, I want a blend I can add to the pot; for a dish needing one particular vegetable, I would rather choose it separately. |
| Preparation | Check whether the pack gives hob or microwave instructions. For steam bags, check the microwave directions and whether the bag stays unopened during cooking. | On busy evenings, a portioned microwave side may be useful; when batch cooking, I can use a loose bag and my usual pan. |
| Ingredients | Read the current ingredient and allergen information. Marks & Spencer describes its soffritto mix as carrots, celery and onions. | I need to know whether a prepared base contains celery or another ingredient that does not suit the dish. |
| Portions and storage | Check the pack size, freezer instructions and how much you can use at once. Follow the product’s directions on cooking from frozen and refreezing. | A loose bag lets me add different amounts across meals; separate steam bags suit sides cooked one portion at a time. |
Common mistakes to avoid
-
Assuming every mix works as a stew base
A plain mixed bag, a casserole blend and a soffritto contain different combinations of vegetables. The wrong blend may leave you needing other ingredients for the recipe.
Read the ingredient list against the dish you plan to make. Marks & Spencer’s soffritto contains carrots, celery and onions, including the allergen celery.
-
Treating frozen vegetables as ready to eat
The Waitrose Essential peas and Birds Eye Steamfresh mix have cooking instructions for use from frozen. Steam bags also require care when handling their hot contents.
Follow the instructions on the pack you buy, including its cooking method and warnings about opening the bag or refreezing after thawing.
-
Relying on a familiar product name instead of the current label
Prepared blends can contain ingredients that matter to a particular recipe or an allergy, and pack instructions may differ between products.
Check the physical pack’s ingredients, allergens, storage directions and cooking instructions before use.

Frequently asked questions
Do frozen vegetables count towards 5 A Day?
Yes. The NHS says an 80g portion of frozen fruit or vegetables counts towards 5 A Day; vegetables cooked into dishes such as soups and stews can count too.
Should I use a plain mix or a casserole or soffritto blend?
Use a plain mix when you want to choose the other vegetables and flavourings yourself. A casserole or soffritto blend can reduce chopping, but check that its ingredients suit the dish; the M&S soffritto contains celery.
Can I cook frozen vegetables straight from the freezer?
Follow the instructions for the individual product. Waitrose Essential peas and Birds Eye Steamfresh Family Favourite Mix provide cooking directions for use from frozen; Birds Eye also says not to pierce its steam bag and warns that the contents will be very hot.
What should I check on a frozen-vegetable pack?
Check the ingredients and allergens against your recipe, then read the storage and cooking directions on the physical pack. The M&S soffritto is raw and must be cooked, while its product guidance says not to refreeze after thawing.
