What You'll Learn
They're easy to grow
Portobello mushrooms are easy to grow and are cultivated in temperature- and humidity-controlled environments. The Agaricus bisporus species, from which portobellos are derived, is the most popular species of edible mushroom and is commercially produced worldwide. Portobellos are simply the mature form of this mushroom species, with white button mushrooms and cremini mushrooms being their immature counterparts.
To cultivate portobello mushrooms, compost is supplemented with nitrogen and gypsum and topped with soil, moss, and ground limestone. Commercial compost typically includes straw, moss, manure, soybean meal, and lime. Before mushrooms are spawned for safety, commercial compost is pasteurized. After about five to six weeks, the mycelium can be manipulated into producing its fruiting bodies, the mushrooms, by adjusting the oxygen, temperature, and humidity levels in the room, a process known as "pinning."
Within a few days of these altered conditions, tiny pinhead mushrooms will begin to appear on the surface of the soil and will double in size nearly every day. Portobello mushrooms are the largest of all cultivated mushrooms and are typically harvested by hand when their brown, slightly flaky caps reach a diameter of 10 to 15 cm (4 to 6 inches). At this stage, the caps are nearly flat, and their undersides reveal fully developed dark brown gills.
Portobello mushrooms are prized for their rich, savory, earthy taste and dense, meaty texture. They are versatile in cooking and can be grilled, pan-fried, or added to pasta, sauces, and stir-fries. Their large caps also make them an excellent meat substitute in vegetarian and vegan dishes.

They're expensive to buy
Portobello mushrooms are expensive to buy for several reasons. Firstly, they are sensitive to changes in the environment, which can lead to longer growth rates and impact their availability. They are also difficult to ship efficiently due to their fragile nature, and they spoil quickly, even when stored in the refrigerator. This means that the price can vary depending on where you shop.
Portobello mushrooms are also in high demand, which can drive up the price. They have a bold, earthy flavour that is often described as meaty, making them a popular ingredient for vegetarian and vegan dishes. They are also known for their nutritional value, including their status as a non-animal source of vitamin D, which can be enhanced through exposure to UV light by commercial growers.
The popularity of portobello mushrooms has also been influenced by their health benefits, particularly their contribution to intestinal health and a healthier immune system. This has led to an increase in demand for the product, which can result in higher prices. Portobello mushrooms are also one of the more common varieties of mushrooms that are considered gourmet, and specialty mushrooms tend to be more expensive.
In addition, the process of growing mushrooms can be challenging and unreliable, which can impact their availability and cost. Mushrooms require specific conditions to grow, including moisture, the right temperature, and the right amount of sunlight. They are also difficult to cultivate artificially, and their growth can be affected by changes in their environment. These factors can contribute to the higher price of portobello mushrooms compared to other produce.

Portobello mushrooms, or Agaricus bisporus, are the mature version of common white or brown mushrooms.

While Portobello mushrooms are a tasty and nutritious option for many, it is important to consider potential health concerns. Some studies have suggested that consuming raw Portobello mushrooms may be linked to an increased risk of cancer due to the presence of agaritine, a compound regarded as a possible carcinogen. However, conflicting evidence exists, and more research is needed to make conclusive claims. Additionally, Portobello mushrooms contain purines that can contribute to gout and kidney stone issues by increasing uric acid levels in the body.
Despite these concerns, Portobello mushrooms offer nutritional benefits, including being a source of B vitamins, potassium, copper, selenium, phosphorus, and fibre. They also contain vitamin D, which aids in calcium absorption, and provide other nutrients such as niacin and vitamin B6.
