How to Trim and Cut Mushrooms in Three Methods

Mushrooms are our fungal friends, and they’re not tricky to chop, trim or dice. In this article we’re going to put the fun into mushroom slicing and prep with easy-to-follow instructions on choosing good mushrooms, cleaning, preparation, and cooking/seasoning. We’ve also got some stunning recipes to get your tastebuds dancing!

Preparation

Choosing mushrooms

Depending on where you live, there can be many different varieties of mushrooms to choose from. Here are our pointers on getting a good mushroom regardless of the species:

  • Look for firm and plump texture
  • Even color
  • No damp spots, wetness, or slime
  • Dry but not dried up in appearance
  • Some dirt on the mushroom is fine
  • Buy loose mushrooms if you can, this allows you to pick the best
  • If your mushrooms have plastic packaging, it should have holes in the plastic to allow air flow – this prevents botulism
  • Mushrooms shrink a lot on cooking – choose small varieties for cooking whole in soups or stews, and large ones for stuffing
  • Portion size – for fresh mushrooms you’ll need about 4 ounces per person

Cleaning mushrooms

Fresh mushrooms should only be cleaned as you’re about to use them. Cleaning them in advance will lead to them losing freshness. The recommended way to clean mushrooms without them absorbing any water content is to wipe them off with a cloth/paper towel or alternatively brush them off gently with a soft brush to remove dirt.

Step 1 patting mushrooms dry

If you’re in a hurry, quick exposure to water isn’t the end of the world with mushrooms, so you can put them into a colander or sieve and quickly spritz them with water from a tap to easily get rid of any dirt.

After rinsing, pat the mushrooms dry gently, or air dry on the counter until you’re going to use them.

Clean dried mushrooms

For dried mushrooms, cover the mushrooms with hot water so that it covers them by about an inch.

Leave them to soak for an hour, then remove the mushrooms from the hot water and keep that hot water, that’s where all the flavor is!

Take the dried mushrooms and rinse them gently under cold running water just to remove any ingrained dirt in the gills, and then pat them dry gently or air dry on the counter until you’re ready to use them.

Preparing tools

For slicing, dicing, and chopping your mushrooms you’ll need the following tools:

  • A sharp knife – we recommend a utility knife but a chef’s knife or paring knife can also be used. A utility knife is a good medium sized tool with a blade of 5 or 6 inches, perfect for mushrooms, but use what you have available and what feels comfortable in your hand. A non – serrated blade is best to avoid damaging the delicate mushroom flesh
  • A chopping/cutting board or firm surface that you can cut on
  • A bowl for putting the chopped mushrooms into
  • A small sealable container for offcuts and remnants you’d like to use or freeze later

How to quarter mushrooms

Quartered mushrooms are perfect to be Sautéed or roasted, and served in a big plate. The size of quartered mushrooms provide a meaty, chewy mouthful that make them excellent as a savory side dish.

Step 1. Trim the stems. Balance the mushroom cap on its side and cut straight down through the top of stem, where it goes into the mushroom. This will sever the stem from the mushroom without damaging the cap, and you can put it aside.

Step 2. Cut in quarter. Simply cut the mushroom at the middle of the cap in half, then cut in another direction in half again.

How to slice mushrooms

Mushroom slices are the most common form of mushroom in the culinary word. You’ll find them on top of pizza, in pasta, on soup, etc.

Step 1. Trim the stems. Place your mushrooms sideaways and use your knife to cut the stems off. It’s the same procedure when quartering the mushrooms.

Step 2. Slice the mushroom into even pieces. Once the stems are removed, take a mushroom and place it cap side down on your cutting surface – the ‘gills’ of the mushroom will be facing downwards. Now, holding it gently but firmly with your fingers so that it doesn’t move, slice with your knife through the mushroom cap widthways, making the gaps between the slices as big or small as you like. Small gaps will give you fine slices, whereas bigger gaps mean chunkier slices. Always chop bigger than you need to allow for shrinkage during cooking!

Pro tip

Mushrooms stems are wonderful, they’re both high in fiber and high in flavor. Instead of discarding them, consider using them chopped as part of the mushroom in your next dish. Alternatively, keep your mushroom stems in the freezer for quick and easy use in soups, stews, and stocks.

Chopping/dicing mushrooms

 To cut mushrooms into little blocks or dice is another interesting way to serve them and is often done for dishes like omelets, or perhaps for topping a pizza or savory pastry.

Here’s how:

Step 1. Trim the stem. We will use a different method this time. Simply grip the base of the mushroom stem firmly and twist it while pulling it off, it will come off easily.

Step 2. Slice the mushroom, cut them into smaller pieces. Once you’ve sliced your mushrooms into slices as above, stack the slices and rotate the pile 90 degrees. Now chop across the mushrooms again, this will give you dice or cubes of mushroom. You can chop the blocks of mushrooms as chunky or as small as you like, depending on what you’re using them for.

Step 3. Mince mushrooms. For minced mushrooms, you’re going to cut the blocks VERY fine, so that you end up with tiny blocks. This will mean cutting across the mushroom flesh from different directions to give a fine texture.

Seasoning your mushrooms for cooking

Many herbs, spices and seasoning liquids pair beautifully with mushrooms and here are some suggestions for you to try:

  • Garlic
  • Black and white pepper
  • Lemon
  • Ginger
  • Chili – either dried or fresh
  • Coriander/Cilantro
  • Sage, rosemary, thyme, oregano, and dill
  • Parsley – parsley butters take mushrooms to the next level

When to season mushrooms

Herbs and other seasonings can be used throughout the cooking process for mushrooms, you season as you see fit! However, salt should be added only at the end of the cooking process. Why?

Salt leaches moisture from mushrooms as they cook, meaning that instead of frying or roasting nicely along, they’ll be sitting in and steaming in their own liquid, which is not the texture that you want. Prevent this problem and preserve their firmness and flavor by only salting the mushrooms right before serving.
