Portobello mushrooms: The mature version of the chestnut mushroom, they are great for grilling and stuffing due to their large cap size and meaty texture.

Shiitake mushrooms: These East Asian natives offer a distinctive umami flavour, excellent for stir-fries, soups, and noodle dishes.

Porcini mushrooms: Also known as ceps in the UK, porcinis are a gourmet choice for their rich, nutty flavour. They’re often found dried rather than fresh.

How to Cook Mushrooms in the Microwave

mushrooms in bowl


250g mushrooms of your choice
2 tablespoons of olive oil or butter
Salt and pepper to taste
Optional: Garlic, parsley, or other herbs and spices


Clean your mushrooms by wiping them with a damp cloth or paper towel. Never soak them in water as they can become soggy, and who wants soggy mushrooms!

Slice your mushrooms if they are large, like Portobello or chestnut mushrooms. Smaller ones like button mushrooms can be left whole.

In a microwave-safe bowl, combine the mushrooms, olive oil or butter, salt, and pepper. Toss well to ensure all the mushrooms are evenly coated.

Cover the bowl with a microwave-safe lid or plate. If using cling film, make sure to pierce it in a few places for venting.

Microwave on high for 2-3 minutes. Stir the mushrooms, then microwave for another 2-3 minutes or until they’re cooked to your liking.

Carefully remove the bowl (it’ll be hot), and let the mushrooms stand for a minute or two. Then, they’re ready to be served!

Pros and Cons of Microwave Cooking Mushrooms

Microwave cooking your mushrooms offers several advantages:

Speed: Microwaving is quicker than conventional cooking methods, saving you time.

Efficiency: It uses less energy than an oven or stovetop, making it an eco-friendly option.

Nutrient retention: Microwaving can help retain more vitamins and minerals as the cooking time is shorter.

However, there are also some disadvantages:

Texture: Microwaving may not provide the same texture as other cooking methods. For example, you won’t get the same caramelisation as you would when sautéing mushrooms.

Taste: The quick cooking process might not allow flavours to develop fully, as they would with slow roasting or simmering.

Uneven cooking: Depending on your microwave’s power, mushrooms might cook unevenly, requiring occasional stirring.

In conclusion, while microwaving mushrooms might not be the traditional method, it’s a handy option for those moments when you’re short on time or lack access to other cooking methods.
