White mushroom varieties

Button mushrooms 

These small white mushrooms are dense and subtle in flavour. They are harvested from the first stages of growth and are perfect for salads and stir-fries, or marinated and sautéed. These little gems are small but sure to please.

Cup mushrooms

Slightly larger than buttons, these white mushrooms add texture and take on the flavours of many meals. Cups are harvested from the second stage of growth, and can be sliced or cooked whole in a wide range of dishes from breakfast through to dinner.

Flat mushrooms

White open flat mushrooms have dark gills and a more intense flavour than the smaller varieties. Cook them whole on the barbecue, or stuff them with your favourite fillings and bake. They’re almost a meal in themselves!


There are so many ways to enjoy mushrooms. Whether simply sautéed with butter, salt and pepper; or stirred into a creamy risotto; or barbecued with a delicious dressing … there are endless possibilities.

Have you thought about eating mushrooms to boost your Vitamin D intake? 

One in four adults are Vitamin D deficient. Yet Vitamin D is essential for strong teeth and bones, normal growth and development, and a healthy immune system.  

You're at a high risk of Vitamin D deficiency if you:

  • Are naturally dark skinned, and need more UV exposure to produce adequate levels of Vitamin D, as the pigment in your skin reduces UV penetration
  • Cover your skin for religious or cultural reasons
  • Are older, housebound or in institutional care
  • Are a baby or infant of a Vitamin D-deficient mother (especially breastfed babies)
  • Have osteoporosis

If you may be Vitamin D deficient, you can easily boost your intake. Mushrooms naturally contain Vitamin D, and we expose our mushrooms to additional light to ensure they have plenty of this important vitamin. You only need to eat 100g of mushrooms – or about three per day – to reach 100% Recommended Daily Intake.

Selection and storage

To select:Look for mushrooms that are firm to touch with a fairly uniform colour. Mushrooms are extremely fragile and prone to bruising, so you may find some marks and blemishes. Stems are a good indication of freshness – look for strong, healthy stems when shopping for mushrooms.

To store: Mushrooms are best kept refrigerated. Keep them in their pre-packed punnet or brown paper bag.

To prepare: Simply wipe mushrooms clean with a damp cloth, or quickly immerse in cold water then pat dry if they have excess peat on them. Avoid peeling your mushrooms before eating, because the skin is packed with essential vitamins and minerals.
