A typical portobello mushroom weighs 85 grams
Portobello mushrooms, also known as brown mushrooms, are open-cup mushrooms that have been allowed to grow to a bigger size and open out. A typical portobello mushroom weighs 85 grams or 3 ounces, though weights can vary. Medium-sized portobellos weigh around 60 to 70 grams, while smaller ones weigh around 50 to 60 grams, and large portobellos can weigh 70 grams or more. These mushrooms are about 4 to 6 inches in diameter and have a darker flesh than button mushrooms.
When planning to serve portobello mushrooms to 75 people, it is important to consider the quantity required per person and the preparation method. As a reference, a typical serving of mushrooms is equivalent to one cup or 70 grams of raw chopped mushrooms. Additionally, mushrooms tend to shrink during cooking, losing about 25% of their original raw weight. For example, 200 grams of raw mushrooms may reduce to 150 grams after cooking.
To estimate the number of pounds of portobello mushrooms needed for 75 people, we can use the average weight of a medium-sized portobello, which is 65 grams (taking the midpoint of the 60-70 gram range). By dividing the total desired quantity by the average weight, we can approximate the number of pounds required. In this case, 75 people multiplied by a 65-gram serving equates to 4,875 grams. Dividing this weight by the number of grams in a pound (453.59 grams) yields approximately 10.75 pounds of portobello mushrooms needed for 75 people.
It is worth noting that this calculation assumes a raw preparation of portobello mushrooms. If they are to be cooked, the quantity may need to be adjusted to account for shrinkage. Additionally, personal preferences for portion sizes and specific recipe requirements may influence the final amount needed.
In summary, to serve 75 people with portobello mushrooms, a good estimate is to procure approximately 10.75 pounds of medium-sized portobellos. This calculation is based on an average weight of 65 grams per mushroom and a raw preparation method. Adjustments may be necessary depending on cooking methods and desired portion sizes.

Medium-sized portobellos weigh 60-70 grams
Portobello mushrooms, also known as brown mushrooms, are open-cup mushrooms that have been allowed to grow to a bigger size and open out. A typical portobello mushroom is 4 to 6 inches in diameter and weighs about 3 ounces (85 grams). However, medium-sized portobellos weigh 60-70 grams or 2.12-2.5 ounces.
To estimate how many pounds of medium-sized portobello mushrooms you would need for 75 people, you must first decide how many mushrooms each person will eat. Let's assume each person will consume one medium-sized mushroom.
Given that medium-sized portobellos weigh around 60-70 grams, you can estimate the total weight required by multiplying the expected number of mushrooms per person by the average weight of each mushroom. In this case, for 75 people, you would need 75 medium-sized portobello mushrooms.
Multiplying 70 grams (the upper estimate for the weight of each mushroom) by 75 mushrooms, you get a total weight of 5250 grams. To convert this to pounds, divide by 453.6 grams per pound, resulting in approximately 11.57 pounds of medium-sized portobello mushrooms needed to serve 75 people.
If you are using smaller or larger mushrooms, the total weight required may vary. Adjustments can also be made based on expected consumption rates and any other dishes being served alongside the portobello mushrooms.

Medium-sized flat mushrooms weigh around 60-70 grams, while large flat mushrooms weigh over 70 grams.
When it comes to serving size, a general rule of thumb is to allow for two portobello mushrooms per person. This means that for 75 people, you would need 150 large portobello mushrooms. At a weight of over 70 grams per mushroom, you would need approximately 7.5 kilograms or 16.5 pounds of portobello mushrooms.
Portobello mushrooms are a great option for large groups as they are not only delicious but also low in calories and fat. They are also a good source of plant-based protein, with each mushroom providing more than 2 grams of protein.

Portobellos are also known as brown mushrooms
Portobello mushrooms, or Agaricus bisporus, are cultivated edible mushrooms sold under a variety of names and at various stages of maturity. They are one of the most commonly consumed mushrooms in the world and are found naturally in grasslands worldwide.
Portobellos are often sold with their stems removed and are best prepared and served soon after purchasing. They can be stored in the fridge for 2-3 days, ideally in the crisper drawer of your refrigerator on the humid setting, with a clean paper towel underneath. They have a rich, savoury, meaty flavour and a dense texture, making them a popular meat substitute in vegetarian dishes.
Portobellos can be cooked in a variety of ways, including grilling, roasting, sautéing, baking, and broiling. They can be used as a substitute for meat in dishes like tacos, fajitas, and enchiladas, or grilled and served as a burger substitute. The caps can also be hollowed out, stuffed, and baked, or used as a base for toppings like a pizza crust.

Portobellos are similar to flat white mushrooms
Portobello mushrooms are often referred to as brown mushrooms. They are flat, open-cup mushrooms that have been allowed to grow to a larger size and open out. They are similar to flat white mushrooms, which are also known as common white mushrooms, or button mushrooms.
Portobellos are the mature form of the mushroom, with a diameter of 4-6 inches, and weighing about 3 ounces (85 grams). They are darker in colour than white mushrooms, with a darker flesh. White mushrooms are the immature form, with a milder taste. They are smaller, with a diameter of 1-3 inches.
Both types of mushrooms are edible and commonly consumed. Portobello mushrooms are often grilled, and they are also used in salads. White mushrooms are commonly cultivated and are the most popular mushroom in the United States.
When sliced, one pound of fresh white mushrooms yields about 5 cups of raw mushrooms, which reduces to about 2 cups after cooking. A typical portobello mushroom is larger, so one pound would yield fewer mushrooms and more cups of sliced mushrooms.
To serve 75 people with portobello mushrooms, you would need to consider the number of other foods being served, as well as the number of guests who may want seconds. As a rough estimate, if each person is served one medium-sized portobello mushroom, weighing 60-70 grams, you would need approximately 4.5 to 5.25 kilograms or 10 to 11.5 pounds of mushrooms.
