They are low in fat and calories, with 100 grams of raw mushrooms containing no fat and only 22 calories
Portabella mushrooms, also known as portobello mushrooms, are a type of Agaricus bisporus mushroom. They are the mature version of common mushrooms belonging to the Agaricaceae family. They are widely consumed and produced in over 70 countries. Portabella mushrooms are known for their rich, earthy, and meaty flavour, as well as their dense, firm texture. They are a popular meat substitute due to their texture and flavour.
Portabella mushrooms are low in fat and calories, making them a nutritious food option. Specifically, 100 grams of raw portabella mushrooms contain no fat and only 22 calories. This makes them an excellent choice for individuals who are conscious of their fat and calorie intake. The low-calorie content of portabella mushrooms also contributes to their popularity as a meat alternative.
The nutritional profile of portabella mushrooms extends beyond their low-fat and low-calorie content. They are a good source of vitamins, minerals, and antioxidants. For example, they provide B vitamins such as riboflavin, niacin, and pantothenic acid. Additionally, they contain dietary minerals like phosphorus and potassium. The antioxidants present in portabella mushrooms offer additional health benefits, such as reducing inflammation and potentially protecting against cancer.
Portabella mushrooms are versatile in the kitchen and can be prepared in a variety of ways due to their large size. They can be grilled, baked, sautéed, or broiled. The stems are edible but can be woody, so cooks often use them for making stock or chop them finely for use in various dishes. The caps are particularly popular as a meatless burger alternative, as they resemble the texture and flavour of a burger patty. Portabella mushrooms are best prepared soon after purchasing, but they can be stored in the refrigerator for 2 to 3 days.
Portabella mushrooms have a long history, with wild versions of the species growing in grasslands, forests, and near human dwellings since ancient times. They are native to Eurasia and North America and have been cultivated for over 300 years, with their commercial cultivation first described in the early 1700s. The name "portabella" or "portobello" likely originated from marketing campaigns in the 1980s, with potential linguistic roots in Italian or English.

Portobello mushrooms are commercially produced in rooms or warehouses with specific temperature and humidity requirements
Portobello mushrooms, botanically classified as Agaricus bisporus, are the larger, earthier, and more mature versions of a common mushroom belonging to the Agaricaceae family. They are widely cultivated edible mushrooms and are one of the most commonly consumed mushrooms in the world. They are known for their rich, earthy, meaty, and brothy flavor, a combination of flavors known as umami.
Portobello mushrooms are commercially produced in specially designed rooms or warehouses that maintain a temperature range of 15.5 to 21 °C (60 to 70 °F) and a humidity range of 65 to 80%. Insulation methods play a crucial role in achieving this optimal temperature range. Using insulated growing rooms or containers helps stabilize temperatures and minimizes external temperature fluctuations. Thermal mass is also important in maintaining stable temperatures, with materials like water or concrete helping to buffer temperature changes.
The temperature requirements for growing Portobello mushrooms are critical for successful cultivation. Research shows a direct correlation between temperature and mushroom production rates, with extreme temperatures significantly impacting the overall yield. For example, if temperatures rise above 21°C during the fruiting phase, there may be a noticeable reduction in the number and size of mushrooms produced. Temperature fluctuations not only affect yield but also the quality of the mushrooms, influencing their flavor profile, texture, and appearance.
Commercial composts used in the production of Portobello mushrooms typically consist of straw, gypsum, horse manure, dried poultry litter, and canola meal. These materials are blended with water and pasteurized. After about five to six weeks, the mycelium can be manipulated into producing its fruiting bodies, the mushrooms, by adjusting the room's oxygen, temperature, and humidity levels through a process called "pinning." After a few days of these altered conditions, tiny pinhead mushrooms emerge and rapidly increase in size. Once they reach the proper size, they are harvested by hand and placed directly into shipping boxes.

They are mature cremini mushrooms with a rich, earthy, meaty, brothy flavour, and a dense, firm texture
Portabella mushrooms are mature cremini mushrooms with a rich, earthy, meaty, brothy flavour, and a dense, firm texture. They are one of the most commonly consumed mushrooms in the world and are sold under a variety of names, including cremini, crimini, and portobello. They are also sometimes referred to as brown mushrooms.
Portabella mushrooms are large, with a circular cap that can range from 3 to 6 inches in diameter. The caps are firm, spongy, and flat, resting on a thick stem. The colour of the cap can range from deep brown to tan, and the gills are typically dark black or brown.
The meaty texture and flavour of portabella mushrooms make them a popular meat substitute, especially in burgers, tacos, fajitas, and pasta. They can be grilled, roasted, sautéed, baked, or cooked under a broiler. When preparing portabella mushrooms for cooking, it is important to check for a firm cap and stem, as shrivelled or soft caps are signs of deterioration. The gills are also edible but may be removed for aesthetic reasons, as they can alter the colour of the dish.
Portabella mushrooms are not only delicious but also nutritious. They contain a range of vitamins and minerals, including B vitamins, potassium, selenium, copper, and antioxidants. They are also a good source of umami flavour, making them a great option for those reducing their salt intake without compromising on taste.

Portobello mushrooms are versatile and can be grilled, roasted, sautéed, baked, or cooked under the broiler
Portobello mushrooms are a versatile ingredient with a rich, earthy, meaty, and brothy flavour. Their texture is more meaty and less spongy than button mushrooms, and they are low in calories and fat. They are also a good source of 15 different vitamins, minerals, and antioxidant phytonutrients, including copper, selenium, and B vitamins.
Portobello mushrooms are the mature version of cremini mushrooms, also known as baby bella, brown, or chestnut mushrooms. They are typically harvested when their caps measure 10 to 15 centimetres in diameter, and their colour ranges from tan to dark brown.
Because of their large size, Portobello mushrooms are very versatile and can be grilled, roasted, sautéed, baked, or cooked under the broiler. They can be stuffed, or the caps can be removed from the stem, grilled, and served as a meatless burger alternative. The stems are edible but can be woody, so cooks may prefer to use them for stock or chop them finely before cooking. The gills are also edible, but some cooks prefer to scrape them out before cooking, especially if they plan to stuff the caps.
To grill Portobello mushrooms, remove the stems and brush both sides with olive oil. You can marinate the caps for up to 30 minutes before grilling, if desired. Season with salt and grill over medium-high heat for 5 to 7 minutes per side, or 10 minutes top side down. Portobello mushrooms can also be sliced into thin strips and used as a meat substitute in dishes like tacos, fajitas, and enchiladas.
Portobello mushrooms are best prepared and served soon after purchasing, but they can be stored in the fridge for 2 to 3 days. When buying fresh Portobello mushrooms, choose firm, plump mushrooms and avoid those with soft spots or bruising, which can be a sign of spoilage.
