How Many Mushroom Slices Is In a Pound?

It can seem frustrating to try a new recipe and not know how much of an ingredient to purchase at the store. Sometimes they give you a quantity of mushrooms in volume (2 cups), sometimes as a weight (8 ounces) and still others the mushrooms are given as a produce description (2 large portabellas). But what are they really talking about? So how much is in a mushroom? In order to help make cooking easier we did some experiments to help tell you exactly how many mushrooms you need to buy.

To answer How many mushrooms in a cup we went to the grocery store to check out the produce section. After surveying the selection we discovered that 1 pound is equal to 20 to 24 medium-sized fresh button mushrooms. We decided to use 1/2 pound of mushrooms or about 10 to 12 button mushrooms for our calculation sample.

We then started chopping and found it took about 3 ounces or 4 to 5 button mushrooms either sliced or chopped to reach the 1 cup mark. A half-pound of fresh button mushrooms yields about 2 ¾ cups chopped or 2 ½ cups sliced. In addition, If you sliced 1 pound of fresh button mushrooms, your resulting 5 cups of raw would turn into about 2 cups after cooking them. A typical portobello is 4 to 6 inches in diameter and weighs about 3 ounces (85 grams), with a darker flesh than the button mushroom.

Did you know that mushrooms are a fungus, not a vegetable plant? When cremini mushrooms got "old", dark and big, no one would buy them until someone gave them a new name and presto -- portobello mushrooms were born, with a premium price to boot.

Next time your recipe calls for a cup of whole, chopped or sliced mushrooms you'll feel confident knowing how many mushrooms you need. You can also use our conversion tool below for any custom how many mushrooms in a... measurements you need.

How to Store ½ Pound Mushroom Bag

General How to Store Mushroom Info

To start with the freshest mushrooms, purchase ones that are firm and evenly colored; avoid ones that have soft dark spots or are damp looking.

Short Term Mushroom Storage

Store fresh unwashed mushrooms in the humid environment of the crisper section, or wrap in paper towels and place in a plastic bag in the refrigerator. Enoki and oyster mushrooms will hold for 2 to 3 days; other fresh mushrooms will maintain their flavor and quality in the refrigerator for 5 to 7 days.

Mushroom Long Term Storage

Do not store raw mushrooms, they will turn mushy; blanched (most common) or sauteed mushrooms will freeze nicely for future use in cooked meals.

To prevent mushrooms from turning dark when thawing, add 1/4 teaspoon of citric acid or 1/4 teaspoon of orange, lime, or lemon juice to the pot of boiling water. Place sliced or chopped clean mushrooms, in boiling water for about 2 minutes. Immediately cool mushrooms in ice water to stop the cooking process. Once the mushrooms have cooled, place in an airtight container and freeze. When stored at 0°F (-17.8°C), the mushrooms will keep for 1 year.

Mushrooms may be dried or pickled.

Mushroom Side Notes

There are thousands of varieties of mushroom, some of the more common fresh mushrooms are: button, chanterelle, enoki, morels, oyster, Portobello, shiitake, and straw.
