What You'll Learn
Oyster mushrooms and garlic
Oyster mushrooms (Pleurotus ostreatus) are a type of edible mushroom that are shaped like oysters. They are one of the most popular mushrooms in the world and are commonly enjoyed in dishes like pasta and stir-fries. Oyster mushrooms are loaded with fibre, vitamins, minerals, and other important nutrients. They are also low in carbohydrates and calories, making them a good choice for people following low-carb dietary patterns.
Oyster mushrooms have a delicate texture and a nutty flavour. They are full of umami, which means they don't need much seasoning. However, oyster mushrooms are often paired with garlic to enhance their flavour. Garlic is known for its strong, pungent taste that can complement the mildness of oyster mushrooms.
One popular way to cook oyster mushrooms is to sauté them with garlic. This involves pan-frying the mushrooms with butter, garlic, and parsley. The mushrooms are cooked over medium-high heat until they develop a golden brown crust. The butter, garlic, and parsley are then added to the pan and cooked until melted and fragrant. This dish can be served as a side or over pasta.
Another way to enjoy oyster mushrooms and garlic is to make mushroom toast. This involves melting cheese over toasted slices of garlic bread and spooning sautéed oyster mushrooms on top. Oyster mushrooms can also be added to pasta sauce, along with cooked pasta and Parmesan cheese.
For a simple side dish, oyster mushrooms can be pan-fried with garlic butter. The mushrooms are cooked in a skillet over medium heat and tossed with soy sauce. Butter and garlic are then added to the pan and cooked until tender. This dish can be seasoned with salt and pepper to taste.

Oyster mushrooms in pasta
Oyster mushrooms are a delicious and healthy addition to any pasta dish. They are known for their impressive health-promoting properties and are loaded with fibre, vitamins, minerals, protein, and antioxidants. Oyster mushrooms also have a unique and delicate flavour, with a nutty, buttery taste and a pleasant umami flavour.
When preparing oyster mushrooms for pasta, it is important to first clean and trim them. Oyster mushrooms grow on tree bark, so they are usually quite clean, but it is best to gently wipe them with a soft towel to remove any debris. The hard base stem should be sliced off, as it can be tough to chew. It is also a good idea to trim the woody stem at the base of each clump of mushrooms, as it can be a bit chewy.
Once the mushrooms are cleaned and trimmed, they can be cooked in a variety of ways. Searing or pan-frying is a popular method, as it gives the mushrooms a tasty crust. Simply heat some oil in a large pan over medium-high heat and cook the mushrooms in a single layer until golden brown. You can also poach the mushrooms in butter and cream before tossing them with the pasta.
When making oyster mushroom pasta, any type of pasta can be used, from pappardelle to linguine to gluten-free options. The creamy mushroom sauce is a popular choice, made with fried oyster mushrooms, garlic, cream, and parsley. This sauce is easy to make and can be customised with various herbs and cheeses. Simply cook the mushrooms in butter until golden brown, then add the garlic, salt, and pepper. After a minute or two, add the cream, pasta water, and parsley, and simmer for a few minutes.
This creamy oyster mushroom pasta is a perfect weeknight dinner, full of flavour and packed with nutrients. It is also a flexible recipe, allowing for substitutions and additions to suit individual tastes. For example, the oyster mushrooms can be substituted with shiitake, cremini, or button mushrooms, or you can add ingredients like pancetta or green onions.

Oyster mushrooms in stir-fries
Oyster mushrooms are a versatile ingredient that can be used in stir-fries to create a range of tasty and healthy dishes. They are known for their delicate, mild flavour and slightly meaty texture, making them a popular meat substitute in vegan dishes.
Ingredients
Oyster mushrooms can be combined with a variety of vegetables to create a nutritious and colourful stir-fry. Some popular vegetable options include:
- Bell peppers
- Spinach
- Cabbage
- Snow peas
- Snap peas
- Baby corn
- Broccoli
- Carrots
- Bok choy
- Celery
- Green onions
- Ginger
- Garlic
Noodles
In addition to vegetables, oyster mushroom stir-fries can also include noodles. Here are some noodle options that pair well with oyster mushrooms:
- Soba noodles: Made from buckwheat flour, these noodles add an earthy flavour to the dish, but they can be tricky to cook as they tend to stick together.
- Udon noodles: Chewy Japanese udon noodles made from wheat are an ideal texture for a stir-fry.
- Cellophane noodles (glass noodles): Made from potato starch, these noodles hold up well in a stir-fry.
- Rice noodles: Rice noodles are neutral in flavour and softer in texture than wheat noodles, so they should be added at the end of the cooking process.
Marinade and Sauce
To enhance the flavour of your oyster mushroom stir-fry, you can marinate the mushrooms before cooking. Here is a simple marinade recipe:
- 1 tbsp tamari
- 2 tsp rice vinegar
- 1-2 tsp maple syrup
- 2 tsp sesame oil
- 1 tsp liquid smoke (optional)
For the sauce, a combination of oyster sauce and dark soy sauce is a popular choice. You can also add spices like Szechuan peppercorn powder or ground black pepper to add some heat.
Cooking Instructions
- Cut the oyster mushrooms into bite-sized pieces.
- Heat oil in a wok or skillet over medium-high heat.
- Stir-fry the mushrooms until they are golden brown, about 3-7 minutes.
- Add the vegetables and cook until tender.
- Combine the cooked noodles, sauce, and mushrooms in the wok or skillet.
- Garnish with ingredients like toasted sesame seeds, roasted peanuts, or fresh coriander.
- Serve hot with a bowl of fresh rice.
Tips
- It is recommended to clean the mushrooms with a damp paper towel or a pastry brush instead of rinsing them directly with water, as mushrooms tend to soak up water easily.
- When frying the mushrooms, avoid moving them too frequently. This helps remove extra water content and concentrate the flavour of the oyster sauce.

Oyster mushrooms in supplements
Oyster mushrooms, or Pleurotus species, are a group of edible gilled mushrooms. They are neither plants nor animals but a type of fungus. Oyster mushrooms are commonly enjoyed in culinary dishes and are also used in supplements.
Oyster mushrooms have been used in traditional medicine for centuries. They are known for their health-promoting properties and contain a variety of powerful compounds. They are rich in antioxidants, which are substances that help reduce or prevent cellular damage in the body. Oyster mushrooms contain higher amounts of antioxidants than other types of cultivated mushrooms. They are also a good source of ergothioneine, an amino acid with potent antioxidant activity.
Oyster mushrooms are also used in dietary supplements. Nammex, for example, produces organic oyster mushroom extract that is processed by hot water extraction into a fine powder suitable for encapsulation or beverages. Their mushroom extracts are commonly used as nutraceuticals, dietary, and nutritional supplements. They are also used as a component ingredient in nutritional supplements and vitamins. Oyster mushrooms are also used in many food products, including meal replacement and energy bars, snack bars, drinks, sauces, seasonings, chocolates, teas, and coffee.
Oyster mushroom supplements have been found to have several health benefits. They may support the immune system, as oyster mushroom extract has been shown to heighten the immune system by activating interferon-γ (IFN-γ), a molecule that protects against infection. Oyster mushrooms may also have antiviral and antibacterial effects. In one study, a combined pleuran, vitamin C, and zinc supplement improved symptoms of the herpes simplex virus type 1 (HSV-1) and reduced the duration and severity of respiratory symptoms. Oyster mushrooms may also have anti-inflammatory properties, as a 2020 rat study found that treatment with P. ostreatus extract significantly reduced induced paw inflammation.
In addition to their potential immune and anti-inflammatory benefits, oyster mushrooms may also have gut health benefits. A 2021 rodent study found that supplementing the diet of obese rats with oyster mushrooms decreased the growth of pathogenic bacteria and increased the production of beneficial short-chain fatty acids in their guts. Oyster mushrooms may also have anti-tumor properties, although more research is needed to confirm this.

Oyster mushrooms in traditional medicine
Oyster mushrooms, or Pleurotus ostreatus, are edible fungi widely available in North America and Europe. They are commonly used in traditional medicine to treat a variety of health conditions. Here are some ways oyster mushrooms are used in traditional medicine:
Cholesterol and Heart Health
Oyster mushrooms have been shown to improve cholesterol levels. They contain a molecule similar to the cholesterol-lowering drug Lovastatin, and beta-glucan, which aids in metabolizing fat. Additionally, oyster mushrooms may promote heart health by reducing risk factors such as high cholesterol and high blood pressure.
Diabetes and Blood Sugar Regulation
Oyster mushrooms may help regulate blood sugar levels. Studies have shown that consuming powdered P. ostreatus reduced post-meal blood sugar levels in people with and without type 2 diabetes. Oyster mushrooms have also exhibited hypoglycemic activity, which may be due to increased insulin secretion and improved glucose utilization.
Infections and Antifungal Properties
Oyster mushrooms are known for their antifungal properties. A compound called pleurostrin, derived from oyster mushrooms, has been found to decrease cholesterol biosynthesis. Additionally, oyster mushrooms have been suggested to have beneficial effects on infections, with potential anti-allergic effects in children with respiratory tract infections.
Cancer and Antitumor Activity
While oyster mushrooms have not been shown to treat cancer in humans, they have exhibited antitumor properties in preclinical studies. Oyster mushrooms contain compounds like pleuran, a beta-glucan, which has been linked to a reduced development of precancerous cells in mice.
Traditional Chinese Medicine (TCM)
In TCM, oyster mushrooms are known as ping gu or hao gu. They are classified as a warming food with sweet and pungent qualities, believed to support the liver and kidneys, and improve energy levels. TCM recommends oyster mushrooms for various ailments, including impotence, cold hands and feet, general weakness, low back issues, and low energy.
Oyster mushrooms have a long history of use in traditional medicine, and modern science continues to uncover and confirm their potential health benefits. However, it is important to note that further studies, especially in humans, are needed to fully understand and validate the medicinal properties of oyster mushrooms.
