Preparing Portabello Mushrooms: A Simple Guide

Portobello mushrooms are a versatile ingredient that can be used in a variety of dishes. They are known for their 'meaty' texture and can be grilled, baked, roasted, sautéed, or pan-seared. Before cooking, it is important to clean and prepare the mushrooms properly, including removing the stems and gills if desired. When cooking the cap whole, it is recommended to score it lightly to allow steam to escape and prevent distortion. Portobello mushrooms can be marinated in various ingredients such as olive oil, garlic, soy sauce, and spices to enhance their flavour, but care should be taken not to marinate for too long as they are porous and can become too salty. Baking, roasting, or grilling brings out the best flavour in portobello mushrooms, and they can be served as a side or main dish, or used as a vegetarian alternative in dishes like burgers.

Cleaning portobello mushrooms

Portobello mushrooms are a cultivated variety of mushroom, usually grown in sanitized, composted peat moss. However, it is still important to clean them before cooking.

Firstly, remove and discard the stems. The stems are technically edible, but they can be woody and fibrous, and are therefore usually discarded. The stems should pop off when pulled with your fingers, but you may need to use a small knife to help remove them.

Next, use a damp paper towel, mushroom cleaning brush, damp cloth, or sponge to gently rub off any dirt from the caps. Be sure to get the underside of the caps and the stems until no dirt or debris remains.

Finally, remove the gills. The gills are edible, but they will turn your food a dark, unappetizing brown colour. Using a small spoon or knife, gently scrape around the underside of the caps to remove the gills. Be careful not to go too deep into the mushroom’s flesh.

Once cleaned, place the mushrooms in a colander and spray with water until any excess debris is gone. Lay the mushrooms out on clean dish towels and let them dry completely.

Marinating portobello mushrooms

Portobello mushrooms are a versatile ingredient with a "'meaty'" texture. They can be grilled, roasted, sautéed, or used in burgers. Before cooking, it is important to clean the mushrooms by removing the stems and gently rubbing any dirt off the caps with a paper towel.

When marinating portobello mushrooms, it is best not to leave them for too long as they are porous and will absorb the liquid. A quick 10-minute marinade will be enough, but you can leave them for up to 30 minutes if needed. A longer marinade will result in a more intense flavour, but be careful not to let them get too salty.

There are many different marinade recipes to try, but a basic combination of balsamic vinegar, olive oil, soy sauce, rosemary, garlic powder, black pepper, and cayenne will enhance the earthy, umami flavour of the mushrooms. You can also add Dijon mustard to the mix for an acidic kick. Place the mushrooms in a shallow dish with the marinade, coating both sides, or put them in a large resealable plastic bag with the marinade and toss to coat.

If you're cooking the cap whole, it's a good idea to score it lightly on the top side. This will allow steam to escape, preventing the mushroom from distorting as it cooks and providing channels for the marinade flavour to penetrate.

Grilled portobello mushrooms are a popular choice as there's very little clean-up afterward. Simply place the mushrooms on a grill and brush them with the marinade as they cook, cooking for 3-4 minutes on each side.

Grilled portobello mushrooms can be served on their own or as a burger. Stack the grilled mushroom on a bun with cheese, tomato, arugula, and avocado for a hearty, tasty meal.

Marinated portobello mushrooms can also be baked in the oven. Place the mushroom caps in a baking dish with the gills facing up, spoon in the marinade, cover with foil, and bake for 25 minutes at 400 degrees Fahrenheit.

Portobello mushrooms are a delicious and versatile ingredient that can be prepared in many different ways. Experiment with different marinades and cooking methods to find your favourite way to enjoy these "meaty" veggies!

Grilled, roasted, or baked, portobello mushrooms make a tasty and satisfying addition to any meal.

Happy cooking!

Grilling portobello mushrooms

Portobello mushrooms are a tasty, vegetarian-friendly treat, offering a meaty texture and a good size for a burger bun. They are also a versatile ingredient, working well as a side, a light main course, or as an addition to other recipes.

Preparation

Firstly, you will want to clean the mushrooms. Remove the stems and use a paper towel to gently rub off any dirt from the caps. Then, with a small spoon, lightly scrape around the underside of the caps to remove the gills. The gills are edible, but they will turn your dish an unappetizing dark colour.

Marinade

To enhance the flavour of the mushrooms, you can use a basic portobello mushroom marinade. This will bring out the earthy, umami taste of the mushrooms. You can make a marinade with balsamic vinegar, soy sauce, garlic powder, black pepper, cayenne, rosemary, and thyme. You can also add 2 ounces of shredded Parmesan cheese to your marinade, for a little extra flavour.

Place the mushrooms in a shallow dish and add the marinade, coating both sides. Leave to marinate for 10 minutes, or up to 30 minutes if you are busy. However, do not leave them for longer than 30 minutes, as the mushrooms will become too salty.

Grilling

Preheat your grill to 450 degrees Fahrenheit. Place the mushrooms on the grill and brush them with the marinade as they cook. Grill for 3-4 minutes on each side, or 4-5 minutes if you prefer them softer. You can also grill them gill-side up with the lid closed, grilling for around 6-8 minutes. The mushrooms will darken as they cook and will relax and open slightly.

Serving

Portobello mushrooms can be served on their own, or with a topping like Herby Avocado Sauce. They can also be used as a burger, stacked with cheese, tomato, arugula, and avocado.

Storage

If you have leftover mushrooms, let them cool and then place them in an airtight container in the fridge. They will stay fresh for an additional 3-4 days and can be reheated in the microwave or oven.

Baking portobello mushrooms

Portobello mushrooms are a versatile ingredient that can be used in a variety of dishes, from appetizers to mains. They are a mature version of the common white mushroom or crimini, and have a meaty texture that makes them a popular vegetarian and vegan option.

When preparing portobello mushrooms for baking, it is important to first clean them. Remove and discard the stems, then use a paper towel to gently wipe away any dirt from the caps. If the mushrooms are very dirty, you can lightly rinse them with water, but be careful not to soak them as they can become mushy.

To enhance the flavour of the mushrooms, you can create a marinade. A simple combination of balsamic vinegar, soy sauce, garlic, and ginger is a popular choice, but you can also experiment with other seasonings like rosemary, thyme, or black pepper. Coat the mushrooms in the marinade for at least 10 minutes, but no longer than 30 minutes, as they may become too salty.

Preheat your oven to 200°C. Place the marinated mushrooms on a lightly oiled baking sheet, gill-side up. Bake for 15 minutes, then remove from the oven and top with cheese. Return to the oven for another 5 minutes, or until the cheese is melted and golden.

For a stuffed portobello mushroom, you can remove the gills with a small spoon and fill the cavity with your desired ingredients before baking. Fresh basil, thyme, Italian seasoning, goat cheese, parmesan, and mozzarella are all popular choices. You can also use portobello mushrooms as a base for mini "pizzas" or as a bun for a vegan burger.

Baked portobello mushrooms are a delicious and versatile dish that can be served as a main course or a side. They are easy to prepare and can be customised to your taste preferences.

Selecting portobello mushrooms

Selecting the right portobello mushrooms is key to a successful dish. Here are some tips to help you choose the best ones:

First, check the caps and stems of the mushrooms. Look for firm caps and stems, avoiding any that are shrivelled or soft. Portobellos are large mushrooms, so choose bigger ones if you can. A little bit of breakage is okay, but avoid caps with large chunks missing or that fall apart at the touch.

Next, examine the gill structure by flipping the mushroom over. The gills should be dry, with a faint pinkish hue when held up to the light. If they appear deep dark black or wet, the mushrooms are past their prime. You can choose to keep the gills intact or remove them with a spoon, depending on your preference and the recipe.

When buying portobellos, opt for loose mushrooms instead of pre-packaged caps so you can inspect them more closely. Before cooking, wipe the mushrooms clean with a damp paper towel or a damp cloth. Avoid rinsing them directly with water, as they can become mushy. If they are very dirty, you can lightly rinse them, but be sure to cook them immediately afterward to prevent spoilage.
