Family roast cooks
If you need different amounts of each vegetable, separate bags or a loose unseasoned mix let you take out the portions you plan to cook.
Who each format suits
Cooks choosing a particular roast side
A cauliflower, broccoli and carrot mix puts those vegetables in one bag. Separate bags give you more control if someone wants more of one vegetable or none of another.
Cooks with a busy hob
Microwave steam pouches offer a portioned way to prepare vegetables while other parts of the roast are cooking. Check the named vegetables before relying on a pouch for the side you have planned.
What to check before choosing
Start with the vegetables you want on the plate, then choose a pack format that fits your portions and available cooking space.
| Priority | What to check | Your needs |
|---|---|---|
| Vegetable mix | Read the named ingredients. Waitrose & Partners describes its chunky mix as cauliflower, broccoli and carrot, but its standard mixed vegetables as carrots, peas, green beans and sweetcorn. | For a roast with broccoli and cauliflower, I want those vegetables named on the pack rather than assuming any mixed bag contains them. |
| Portion flexibility | Check pack size and whether the vegetables are loose or divided into pouches. Consider how much of each vegetable you will cook. | If people want different vegetables or portions, I would rather choose amounts from loose bags than prepare fixed pouches. |
| Cooking space | Check the exact pack's microwave, hob or steaming directions, including any appliance settings and handling instructions. | When the hob is occupied by the roast, a microwave method gives me another way to prepare the side. |
| Ingredients | Check the current pack for ingredients, allergens and any added seasoning, particularly if someone needs a specific product composition. | I want to know what is already in the vegetables before deciding how to season the meal. |
| Serving size | Plan the amount to cook for each person. The NHS states that 80g of frozen fruit or vegetables counts as one 5 A Day portion. | I want enough vegetables for the people eating, without treating a pack's stated servings as the only portion size I can use. |
Common buying mistakes
-
Assuming every mixed bag contains roast-dinner vegetables
A mix of carrots, peas, green beans and sweetcorn will not supply broccoli or cauliflower if those are part of your planned side.
Read the ingredients: choose a cauliflower, broccoli and carrot mix for that combination, or assemble it from separate bags.
-
Using one cooking time for every pack
Loose vegetables and steam pouches use different preparation methods, so a timing taken from another product may not suit the pack in hand.
Keep the packaging while cooking and follow its instructions for your appliance and the amount being prepared.

Questions about frozen vegetables
Do frozen vegetables count towards 5 A Day?
Yes. The NHS states that 80g of fresh, canned or frozen fruit and vegetables counts as one portion. Check how much you are preparing rather than assuming one pouch or serving suggestion equals 80g.
Will a mixed-vegetable bag contain broccoli and cauliflower?
Not necessarily. Waitrose & Partners describes its standard mixed vegetables as carrots, peas, green beans and sweetcorn, while its chunky mix contains cauliflower, broccoli and carrot. Read the ingredients for the particular bag you intend to serve.
Can I prepare a frozen vegetable side in the microwave?
Yes, if the product provides a microwave method. Steam pouches and loose vegetables can require different dishes or handling, so use the directions on the exact pack rather than transferring a method from another product.
What if someone needs to avoid a particular ingredient?
Check the current physical pack for its ingredient and allergen information before preparation. Do not rely on the general name of a vegetable mix to establish what it contains.
