How Many Mushrooms in a Pound? Mushroom Yield, Raw and Cooked
A pound is about 24 medium white mushrooms, 19 large or 44 small, going by USDA’s nutrient-database weights and its 3% for trimmings. Trimmed, a pound of whole mushrooms gives about 0.98 lb ready to cook. Cooking is where they shrink: the USDA Food Buying Guide gives 0.43 lb of cooked sliced mushrooms per pound.

Good to know
- The Food Buying Guide also lists 0.93 lb of cooked mushrooms per pound when they are trimmed and chopped, far above the 0.43 lb for sliced ones. The guide does not say why the two differ, so weigh a batch the way you cook it.
