Cleaning and preparing portabella mushrooms

Portabella mushrooms are a versatile ingredient that can be used in a variety of dishes, from grilled vegetables to vegetarian burgers. Before cooking, it is important to clean and prepare them properly to ensure the best flavour and texture.

To start, choose mushrooms with a firm cap and stem, avoiding any with shrivelled or soft caps. Check the gill structure by flipping the mushroom over – it should be dry with a faint pinkish hue. If it is deep dark black or wet, it is past its prime.

Once you have selected the freshest mushrooms, it is time to clean them. Use a paper towel to gently wipe any dirt from the caps and stems. Then, with a small spoon, lightly scrape around the underside of the caps to remove the gills. While the gills are edible, they can turn your dish an unappetizing brown colour.

If you are cooking the caps whole, it is recommended to score the top side lightly. This allows steam to escape, preventing the mushroom from distorting as it cooks and ensuring even cooking. It also allows flavours to penetrate more deeply if you are marinating your mushrooms.

When preparing the mushrooms, you may choose to remove the stems, as they can be woody and fibrous, although they are technically edible. You can also use the stems to flavour stock. If you are marinating your portabella mushrooms, place them in a shallow dish with the marinade, coating both sides. Ten minutes is enough time to enhance the flavour, but you can leave them for up to 30 minutes.

Grilling portabella mushrooms

Grilled portabella mushrooms are a delicious and healthy treat, perfect for a summer barbecue. They are a great vegetarian option, offering a satisfyingly meaty texture. Before grilling, it is important to clean the mushrooms. Remove the stems and use a damp paper towel to gently wipe any visible dirt from the caps. With a small spoon, lightly scrape around the underside of the caps to remove the gills—this will extend the shelf life of the mushrooms.

When selecting portabella mushrooms, look for those with firm caps and stems. Avoid any that are shrivelled or soft. The gills should be dry, with a faint pinkish hue. Deep dark black or wet-looking gills indicate the mushrooms are past their prime.

To prepare the mushrooms for grilling, it is best to lightly score the top side of the cap. This allows steam to escape, preventing the mushrooms from distorting as they cook and ensuring even cooking. It also allows any marinade to penetrate more deeply. A simple marinade of oil, balsamic vinegar, garlic, and herbs will enhance the earthy, umami flavour of the mushrooms. You can also add onion, black pepper, cayenne, rosemary, or thyme.

Place the mushrooms in a shallow dish, gill-side up, and pour the marinade over them. Allow them to marinate for around 30 minutes to an hour. Preheat your grill to medium-high heat and grease the grate. Place the mushrooms on the grill and cook for 3-5 minutes on each side, or until tender and caramelized. Brush the mushrooms with the marinade as they cook, and continue cooking until they are soft and browned.

Grilled portabella mushrooms make a great side dish or can be served in a bun with toppings such as cheese, tomato, arugula, and avocado. They are a versatile and tasty option for any barbecue or grilled meal.

Marinating portabella mushrooms

Portabella mushrooms are a versatile ingredient that can be stuffed and roasted, grilled, or thinly sliced and sautéed. Before cooking, it is important to clean the mushrooms. Start by removing and discarding the stems, then use a paper towel to gently rub off any dirt from the caps. Next, use a small spoon to lightly scrape around the underside of the caps to remove the gills. While the gills are edible, they can turn your dish a dark, unappetizing colour.

When selecting portabella mushrooms, look for those with firm caps and stems. Avoid shrivelled or soft caps. Flip the mushroom over and examine the gill structure—it should be dry, with a faint pinkish hue. If it is deep dark black or wet-looking, the mushroom is past its prime.

When preparing portabella mushrooms, marinating is a great way to enhance their flavour. However, mushrooms are extremely porous, so avoid marinating them for too long, or they will become soggy and fall apart. About 30 minutes is usually sufficient.

To make a basic marinade, combine balsamic vinegar, olive oil, soy sauce, rosemary, garlic powder, black pepper, and cayenne in a shallow baking dish. Whisk the ingredients together, then add the mushrooms and turn to coat both sides. Allow the mushrooms to sit in the marinade for 5 minutes on each side, or up to 30 minutes for a more intense flavour.

After marinating, heat a grill or large skillet to medium heat (about 350 to 400 degrees F). Brush the grill with oil to prevent sticking. Remove the mushrooms from the marinade, shaking off any excess, and place them on the grill. Cook for 3-4 minutes on each side, or until caramelized and deep golden brown. Brush the mushrooms with the remaining marinade several times during cooking.

Your grilled portabella mushrooms are now ready to serve! They can be enjoyed on their own or with toppings such as herby avocado sauce, cheese, spinach, tomato, or avocado. Stack them on a bun for a delicious mushroom burger. Grilled mushrooms are best fresh but can be stored in the refrigerator for a few days.

Sautéing portabella mushrooms

Selecting and Cleaning Mushrooms:

Start by choosing fresh portabella mushrooms. Look for those with firm caps and stems, avoiding any with shrivelled or soft caps. Examine the gills, which should be dry with a faint pinkish hue in the light. Clean the mushrooms with a damp paper towel, removing any dirt. Optionally, you can remove the gills, as they can turn your dish an unappetizing hue.

Preparing the Pan:

Slice the mushrooms into strips about 1/4" thick. Use a large pan and heat it to medium-high. Add 1-2 tablespoons of olive oil, avocado oil, organic canola oil, or butter to the pan. You can also add some garlic-flavoured olive oil for extra flavour.

Sautéing the Mushrooms:

Add the mushrooms to the pan. Do not overcrowd the pan, and work in batches if necessary. Sauté the mushrooms until they release their water and it evaporates, then they will start to brown. If desired, add a pinch of kosher salt to encourage the mushrooms to release their water. Continue cooking until the mushrooms are golden brown.

Adding Flavour:

Once the mushrooms are browned, you can add additional ingredients to enhance their flavour. Add 2 tablespoons of butter to the pan and turn the heat down to medium. Include 2 tablespoons of balsamic vinegar, which will give the mushrooms a tangy flavour. You can also add some garlic and shallots, sautéing for about 30 seconds before adding the mushrooms.

Serving:

Season the mushrooms with salt and pepper to taste. You can also add herbs like parsley, thyme, or basil. Sprinkle with grated Parmesan cheese for an extra touch. Serve hot, warm, or at room temperature.

Enjoy your delicious and flavourful sautéed portabella mushrooms!

Buying and storing portabella mushrooms

Portobello mushrooms, also known as Portabello or Portabella, are medium to large in size, averaging 10 to 15 centimetres in diameter. They have a dense, meaty, sturdy, thick, and hearty texture and can be eaten raw or cooked. When buying portobello mushrooms, look for those with plump caps ranging in colour from tan to dark brown. The caps may have a smooth or slightly wrinkled texture and are sometimes covered in small flaky scales. The gills underneath the cap should be fully developed, dark brown, crowded, narrow, and free-standing. Some Portobello mushrooms may also be sold with their stems partially intact, with an ivory to white hue and a fibrous consistency.

Portobello mushrooms can be purchased from grocery stores or grown at home. If you choose to buy them, look for fresh mushrooms that are free from bruises and blemishes. Check the underside of the caps to ensure the gills are intact and not dried out. Select mushrooms with firm stems, avoiding any that appear slimy or shrivelled.

If you want to grow your own portobello mushrooms, you can purchase a mushroom growing kit online or from a local gardening store. These kits typically include a growing medium, spores, and instructions. Alternatively, you can create your own growing setup by purchasing the spores and preparing a growing medium yourself. Portobello mushrooms grow best in a warm and humid environment with indirect sunlight. They thrive in manure-based compost mixed with peat moss, and it takes a few weeks for the spores to develop into mushrooms.

When storing portobello mushrooms, keep them in a paper bag in the refrigerator for up to one week. Ensure the mushrooms are unwashed and whole to extend their shelf life. If you wish to store them for longer, cook the mushrooms and then freeze them, which will keep them fresh for several months.
