Portobello mushrooms are a delicious and nutritious addition to many dishes, but their tendency to become soggy during cooking can be frustrating. Follow these tips to help keep your portobellos from getting waterlogged and limp.
Dry the Mushrooms Thoroughly
Before cooking portobello mushrooms, it’s important to make sure they are as dry as possible. Give them a quick rinse or wipe with a damp paper towel to clean them. Then gently pat them dry with paper towels or a clean kitchen towel. Allow the mushrooms to air dry for 10-15 minutes before cooking. This helps remove any excess moisture on the surface that would cause steaming and sogginess.
Remove the Gills
The underside gills on portobello mushroom caps can trap moisture and lead to a wet, slimy texture. Use a spoon to gently scrape out the black gills before cooking. This opens up the underside, allowing steam to escape and air to circulate instead of getting trapped inside making the mushrooms waterlogged.
Salt the Mushrooms
Sprinkling the portobello caps and stems with salt can help draw out excess moisture through osmosis. The salt will pull water to the surface of the mushroom where it can then evaporate off. Salting about 10-15 minutes before cooking gives time for this moisture-absorbing effect to take place. Just be sure to pat away any beads of water that appear on the surface.
Cook Without Crowding
When sautéing, grilling, or roasting portobello mushrooms, be sure not to crowd too many into the pan or baking sheet. Overcrowding causes the mushrooms to steam in their own juices rather than brown. Leave space between each one so air can circulate and moisture can evaporate.
Use an Absorbent Cooking Surface
Line the pan or baking sheet with something absorbent that will soak up moisture released by the mushrooms as they cook. Good options include paper towels, clean kitchen towels, parchment paper, or aluminum foil with the shiny side down. The absorbent material wicks away excess liquid rather than letting it pool under the mushrooms.
Cook Mushrooms Thoroughly
Don’t stop cooking as soon as the mushrooms begin to brown. Continue sautéing, grilling, or roasting them until they’ve released all their internal moisture and the surface looks dry. The longer cooking time helps the moisture fully cook off so it doesn’t linger inside and make the interior soggy.
Cook Mushrooms Fully Before Adding to Other Ingredients
If adding portobello mushrooms to soups, stews, pasta dishes, or grain bowls, resist the urge to mix them in raw. Sauté or roast them first until cooked through and moisture has evaporated before combining them with other ingredients. This prevents them from leaching liquid into the finished dish.
Pat Mushrooms Dry After Marinating
Marinades are great for adding flavor to portobellos, but the liquid can make them turn out soggy. After marinating, pat the mushrooms with paper towels to remove excess marinade clinging to the surface before cooking.
Remove Mushrooms from Canned Liquid
When using canned portobello mushrooms, drain them well and pat dry. Don’t use any of the canning liquid in the recipe or it can make the mushrooms slimy.
Don’t Wash Mushrooms Before Cooking
Washing portobello mushrooms right before cooking adds extra unnecessary moisture. Brush or wipe away any dirt instead. Save rinsing just for cleaning mushroooms after harvest.
Use Oil for Sautéing
Oil is less likely than butter to cause steaming and sogginess when sautéing. The oil coats the mushrooms and helps moisture evaporate rather than getting trapped.
Add Acid for Cooking Liquid
If braising portobello mushrooms or cooking them in liquid, add an acid like lemon juice, vinegar, or wine. The acid helps inhibit the release of moisture. Just avoid overdoing it as too much acid can make the mushrooms mushy.
Lower the Heat
High heat causes portobello mushrooms to release moisture faster than it can evaporate away. Cook them over medium or medium low heat instead to give the liquid time to cook off gradually as the mushrooms brown.
Skip Wet Marinades
Marinades containing lots of oil or other liquids can make portobellos slimy. Opt for dry spice rubs or drier marinades instead of very wet, saucy ones.
Pat Before Breading
If breading or battering portobello mushrooms, be sure to pat them very dry first. Any residual moisture on the surface will turn the coating gummy or soggy.
Bake Portobellos on a Rack
When roasting portobello mushrooms in the oven, place them gill-side up on a rack over a baking sheet. The rack allows air flow all around the mushrooms to evaporate moisture.
Conclusion
Following these tips will help prevent excess moisture from ruining the texture of portobello mushrooms. Taking steps to limit sogginess allows you to enjoy their full, meaty flavor in any dish you choose to use them in. Crispy, browned portobellos are within your reach with the right preparation techniques.

Grilling Portobellos
Grilling is a quick and tasty way to cook portobello mushrooms without ending up with soggy results. Here are some grilling tips:
- Clean mushrooms with a damp towel rather than rinsing

- Grill uncovered and flip frequently to allow moisture to cook off
- Move to indirect heat if mushrooms start to get too soggy
- Grill until mushrooms look dry and slightly shriveled
Roasting Portobellos
Roasting is another great option for avoiding soggy mushrooms. Follow these tips:
- Clean and dry mushrooms well
- Scrape out gills
- Toss mushrooms in a little oil, salt, and pepper
- Spread out on a parchment lined baking sheet

Sautéing Portobellos
With the right technique, you can sauté portobellos without them getting waterlogged:
- Pat mushrooms very dry

- Mushrooms should look browned and shriveled when done
Marinating Portobellos
For full flavor without sogginess, marinate mushrooms properly:
