Mushrooms add big flavor to so many dishes with their earthy freshness. Before you toss them into a recipe, you need to know how to clean mushrooms properly, especially because the best way to clean mushrooms depends on the variety.
With the wide variety of mushrooms available, it's easy to add those nutrient-rich, heart-healthy fungi to our diets as vegetarian main dishes or stuffed for an easy party food for guests. Since mushrooms grow so low to the ground, they tend to still be a bit dirty when you buy your cartons at the grocery store. The keys to great-tasting mushrooms is to buy them fresh and clean mushrooms without letting them get waterlogged. Follow these tips on purchasing quality mushrooms and how to clean, store, and prep them, including directions on how to clean morel mushrooms when you're lucky enough to get some of these highly-sought-after mushrooms.
How to Clean Mushrooms
The only "tool" you'll need is a paper towel.
For All Mushrooms (Except Morels)
Use a damp paper towel or a soft mushroom brush (Joie Mushroom Brush, $6.10, Walmart) to wipe each mushroom, one at a time, to remove any dirt. We can imagine the follow-up question now: How do you clean mushrooms when you don't have time to individually wipe each one? We grant you permission to lightly rinse the mushrooms with cool water and pat dry with paper towels. Don't soak the mushrooms. Because they absorb water like little sponges, mushrooms won't brown nicely when cooked if they are full of water.

How to Clean Morel Mushrooms
Cut a thin slice off the bottom of each stem and, if desired, cut the mushrooms in half from stem to tip. Rinse in cool water to remove any dirt and insects. If the mushrooms look clean, this may be enough; if not, a short soak in lightly salted water brings out any remaining insects and dirt. If soaking, change the water as needed until dirt and debris are removed. Rinse the morels well, pat dry, and use in place of other mushrooms in recipes.

How to Clean Sliced Mushrooms
Most of the time, pre-sliced mushrooms at the store will say they've been washed already, but if you see some dirt, you may want to clean again. To clean sliced mushrooms, give them a shake in a colander to loosen any dirt, then give them a quick rinse just before you're ready to cook. Dry them off with paper towels or a clean tea towel.
How to Clean Mushrooms for Stuffing
- For portobello mushrooms, clean as directed above. Gently twist off or cut off the stem of each mushroom. You can reserve the stems to use in the stuffed mushroom filling, if desired. Holding a mushroom in one hand, use a spoon to gently scrape the gills from the underside of the portobello mushroom cap; discard the gills. Repeat with remaining mushrooms. Now they are ready to stuff.
Test Kitchen Tip: Gills do not have to be removed from portobello mushrooms to eat them, but if you're planning to stuff them, the gills will be in your way. For grilled portobello burgers and other nonstuffed mushroom recipes, you may leave the gills for richer flavor.
- For white mushrooms and cremini mushrooms, choose fairly large mushrooms for stuffing. Clean as directed above. Gently twist off or cut off the stem of each mushroom. You can reserve the stems to use in the stuffed mushroom filling, if desired. Use a teaspoon to fill each mushroom with desired filling.
How to Cut Mushrooms
- After cleaning mushrooms, trim thin slices from the ends of the stems.
- Using a sharp knife, non-serrated knife (Wusthof Gourmet Chef's Knife, $51.96, Sur La Table), cut the mushrooms into halves or quarters, or slice or chop as needed.
Test Kitchen Tip: If a mushroom stem is tough, trim it. Always remove shiitake mushroom stems before cutting; they are very tough and not pleasant for eating.
Selecting and Storing Mushrooms
- Mushrooms are fresh if they are firm, plump, and free from bruises with no visible moisture on the outside. Avoid slimy or spotted mushrooms.
- For white mushrooms, also called button mushrooms, the gills on the underside should be tightly closed.
- Store mushrooms (except morels) unwashed in the refrigerator for up to two days in a paper bag or in the original packaging. Because they need to breathe, mushrooms shouldn't be stored in a plastic bag.
- To store morel mushrooms, clean and wrap mushrooms loosely in damp paper towels or damp clean cotton cloth, and place the bundle in a bowl. Store in the refrigerator for up to three days, keeping towels damp so the mushrooms don't dry out.
