Blue oyster mushrooms🍄, scientifically known as Pleurotus ostreatus var. columbinus, are a type of edible mushroom known for their vibrant blue-gray color and mild, earthy flavor.

They are commonly found in temperate and subtropical regions and have gained popularity in recent years due to their nutritional value and culinary versatility.

What are Blue Oyster Mushrooms?

Blue oyster mushrooms belong to the Pleurotus genus, which includes several species of oyster mushrooms. They typically have a fan-shaped cap with a smooth surface and gills that run down the stem.

While their natural habitat is on dead or decaying wood, they can also be cultivated indoors.

Selecting and Storing Blue Oyster Mushrooms

When selecting blue oyster mushrooms, look for ones that are firm and have a fresh appearance. Avoid mushrooms with slimy or discolored caps, as these may indicate spoilage. It’s also essential to choose mushrooms that have not been damaged or bruised.

To store blue oyster mushrooms, place them in a paper bag or wrap them in a paper towel to absorb excess moisture. Keep them in the refrigerator and use them within a week for optimal freshness.

Cleaning Blue Oyster Mushrooms

Before cooking blue oyster mushrooms, it’s crucial to clean them properly. Gently brush off any dirt or debris using a soft brush or cloth. Avoid washing them under running water as they can absorb moisture and become soggy.

How to Cook Blue Oyster Mushrooms: Basic Methods

Blue oyster mushrooms can be cooked using various methods, each bringing out unique flavors and textures. Here are three basic cooking methods you can try: 👇


Sautéing blue oyster mushrooms is a quick and simple way to bring out their natural flavors. Heat a pan over medium heat and add a small amount of oil or butter.

Once the oil is hot, add the mushrooms and sauté them for about 5-7 minutes until they are tender and lightly browned. Season with salt, pepper, and herbs of your choice.


Roasting blue oyster mushrooms gives them a rich, concentrated flavor. Preheat your oven to 400°F (200°C). Toss the mushrooms with olive oil, salt, and pepper, and spread them evenly on a baking sheet.

Roast for approximately 15 to 20 minutes until they are golden brown and slightly crispy.


Grilling blue oyster mushrooms adds a smoky and charred taste to their natural earthiness. Preheat your grill to medium-high heat. Brush the mushrooms with olive oil and season with salt and pepper.

Place them directly on the grill grates and cook for 3 to 4 minutes per side until they are tender and grill marks appear.
