How Many Calories Are in a Serving of Sautéed Mushrooms?

A serving of sautéed button mushrooms, about 150 grams, cooked with 1 tablespoon of oil averages 120–140 calories. Most of that comes not from the mushrooms themselves but from the oil added to the pan. Since raw mushrooms are mostly water with a little carbohydrate, the same 150 grams cooked with no oil at all stays at just 35–40 calories, showing how decisive the amount of oil in the recipe really is. Why do mushrooms absorb so much oil? Mushroom's cell structure is naturally spongy; once heated, the water inside evaporates quickly and the emptied cells start soaking up the oil in the pan. Because of this, mushrooms can absorb far more oil relative to their weight than vegetables like potato or carrot do. How much does cutting the oil lower the calories? The same serving sautéed with half a tablespoon of oil instead of a full tablespoon drops to around 90–100 calories; halving the oil halves the calories that come from the oil. Cooked in a non-stick pan with just a few drops of oil, mushrooms can fall to 45–50 calories, quite close to the raw figure and a practical choice for anyone watching their calorie intake. Do different mushroom types change the calories? Button, oyster and beech mushrooms sit close together in calories when raw; all contain about 20–25 calories per 100 grams. Dried mushrooms can reach 250–300 calories per 100 grams once the water is gone, though recipes usually call for only a small amount of the dried form. What is mushroom's nutritional profile? Most of a raw serving's calories come from carbohydrate; protein is relatively high compared with other vegetables. Once sautéed, most of the calories come from the added oil, which changes the total count rather than the mushroom's own nutritional profile. Does garlic mushroom differ from plain sautéed mushroom? Garlic itself is low-calorie; a few cloves add no more than 10–15 calories to the serving. Garlic mushrooms sautéed in butter get their extra calories from the butter, making that version a touch higher than one made with olive oil. Where do the calories in mushroom soup come from? Mushroom soup's calories come largely from added cream or a flour-and-butter roux; the mushrooms themselves add very little to the bowl. A version made with milk instead of cream can carry 50–60 fewer calories per serving, a gap that comes entirely from the fat content of the liquid used. Does grilled mushroom differ from sautéed? Mushrooms grilled with little or no oil carry noticeably fewer calories than the same amount sautéed in a generous amount of oil. The same serving grilled stays around 45–55 calories, while a rich sauté can reach 140; the gap comes entirely from how much oil the cooking method uses. At a glance, a serving of sautéed mushrooms runs anywhere from 40 to 140 calories depending on the oil used. Raw mushrooms are nearly calorie-free on their own — it is the oil in the pan that really decides the total.
