Mushrooms: Storage, Freezing, Reheating and Pregnancy Answers
Written by Jordan Morley · Reviewed against NHS, FSA and USDA FoodKeeper guidance · Last updated 28 October 2026
This page pulls together the 6 mushrooms answers on the site: how long it keeps, whether you can freeze it, whether you can reheat it, where it stands in pregnancy and what applies while breastfeeding. The table gives the short answer for each; the page behind each row gives the full reasoning, the source and the exceptions.
In pregnancy: Yes — mushrooms are safe to eat during pregnancy and can be enjoyed as part of a healthy, balanced diet.
Worth knowing: Raw mushrooms release a lot of water as they freeze and go soggy. Sautéing them briefly in a little oil or butter before freezing gives a far better result, and they can then go straight into sauces and stews.
