Good to know

  • A cup of sliced white mushrooms (70 g) has about 15 calories and 2.2 g of protein. A large mushroom (23 g) has about 5.
  • Mushrooms shrink a lot as they cook and soak up the oil or butter in the pan. Weigh them raw, as this entry describes, and count the fat on its own line.
  • Because they are low in calories and add bulk, mushrooms can stretch a scramble, a stir-fry, or a meat sauce without adding much to the total.
