Oyster mushrooms are our favorite type of mushrooms. They have an outstanding meaty flavor and we love creating recipes with them. Our top favorite is fried breaded oyster mushrooms.

Ingredients

It is an easy recipe with 5 ingredients:

Crispy Oven Roasted Oyster Mushrooms Recipe - Give Recipe (2)
  • Pearl oyster mushrooms or sliced king oyster mushrooms
  • Salt
  • Pepper
  • Fresh rosemary
  • Olive oil

As you see, it is almost a single ingredient recipe because it calls for oyster mushrooms and seasoning. Salt, pepper and oil are staples of almost any dish and we always have these in our pantry. Fresh rosemary is optional, but its flavor combines very well with the flavor of mushroom. So it is highly recommended.

How To Make

I can’t think of an oyster mushroom recipe easier than this. The method is quite straightforward: Combine everything in a baking sheet and bake. It is that simple! Let me explain it in two stages:

Prepare The Mushrooms

Separate individual mushrooms from the main stem using your hand, like tearing them off the stem. You can use a knife too but I find the tearing method easier. Cut off the tough rubbery ends on the stems. Clean each mushroom with a damp kitchen towel or paper towel.

Roast The Mushrooms

  • First, preheat the oven to 430F/220C.
  • Second, place the cleaned mushrooms on a parchment paper lined baking sheet.
  • Third, brush each of them with olive oil. Sprinkle salt, pepper and fresh rosemary leaves over them. Bake for 25 minutes or until brown and crispy. The baking duration might be different depending on the size of your mushrooms and your oven. So keep an eye on them and check after 10 minutes.

Pro Tip: The smaller the mushrooms are the crispier they get. So if you want something like really crispy mushroom chips, tear or cut the large mushrooms into small pieces. And roast them for 10-12 minutes.

Note About Oven Roasting: I tried both turning the mushrooms over after about 20 minutes and not touching them until the end of the baking duration. The result is pretty similar, so there is really no need to remove the mushrooms from oven and turn them over.

How To Make These In Air Fryer

  • First, preheat air fryer to 360F/180C for about
  • Second, prepare the mushrooms as described above.
  • Third, spritz the fryer basket with oil or cooking spray. Place oyster mushrooms into the basket in a single layer.
  • Fourth, spritz the mushrooms with oil. Sprinkle salt, pepper and rosemary leaves.
  • Finally, cook for 5 minutes, flip them over and cook for another 5 minutes or until crispy and golden brown.

Using Suggestions

We love to snack on these oyster mushroom chips and we mostly enjoy them as they are pairing with cold beer. Believe it or not, these two make a wonderful match.

However, the usage of roasted mushrooms is not limited to this. Some suggestions are as follows:

  • Use them to top your cream of mushroom soup or any other creamy soups.
  • Use them in a keto salad recipe or you can make a vegetarian version of any chicken salad recipe using roasted oyster mushrooms.
  • Use them in sandwiches like avocado turkey sandwich for an extra rich flavor.

FAQs

How do you know if oyster mushrooms are bad?

If the mushroom is firm and dry, it is fresh and good. If it is slimy and too soft, it is bad.

Can oyster mushrooms make you sick?

It is definitely safe to eat them. However, you might have stomach problems if you eat too many of them, especially if you have a fragile metabolism.

Do oyster mushrooms need to be refrigerated?

Yes, keep them in the refrigerator if you are not planning to use them immediately. Put them in a paper bag or wrap them with paper towel and then put in the refrigerator. They keep well for about a week this way.

    I grew my own oyster mushrooms and was so excited to try them. I roasted in the oven for only 15 minutes according to this recipe and they were burned to a crisp, completely inedible. Might recommend a much shorter cooking time to prevent them from burning.

      Hi El,
      We are sorry to hear that it didn't work for you. The duration for baking might change depending on the size of oyster mushroom pieces and on the type of ovens. So it might be better to keep an eye on them when they are in the oven and remove when they are brown enough.
      Thank you for this feedback, we will write it as a note on the recipe.

    Hi! It looks healthy and crispy. Im just wondering if that recipe works if Im planning to store it in paper-bag resealable pouches and sell it online or in grocery store. Would it last long? The crispiness and its quality?

    Pls let me know. Thank you!

      Hi there,

      We wouldn't recommend storing it long. They are the best when served immediately. They will lose their crispiness as they wait.

    I worked in a 4 star restaurant for awhile, and they frequently had these delicious oyster mushrooms. We roasted them in prep, and they were used for multiple different dishes we served. I LOVED snacking on them. I saw that you could order inexpensive grow kits for them on Amazon, so I grew my own due to the fact they are not readily available in stores in small-town Kentucky, lol. I just picked my first harvest, and used this recipe. The only thing I changed was instead of using s&p, I used a spice mix that contains s,p, & garlic. They only needed to roast about 12 minutes, but they were PERFECT. They never even made it to dinner, lol. I couldn't resist and snacked on them until they were gone. Superb.

    Nice recipe! When I lived in Central Asia there was a kind of appetizer from the Uyghur culture using oyster mushrooms pulled into thin strips, dredged in a mix of starch, chili powder, cumin, and salt, deep-fried until crispy and golden. It was amazingly delicious but not the healthiest way of cooking. I wonder if I could make a skinnier version by following your method but substituting the rosemary for chili and cumin.

      Hi Tim,
      That oyster mushroom strips sound amazing! I'm sure they come out really amazing. Have to give it a try! Thanks for sharing this here! We are always into new recipes with oyster mushrooms:)
      As for the healthier version, I think roasting is a good alternative to frying. I guess they get even crispier if roasted in strips.
      Let us know how it turns out!

FAQs

What is the secret to crispy mushrooms? ›

Do I need to soak oyster mushrooms before cooking? ›

Rehydrating dried oyster mushrooms involves soaking them in a bowl of boiling water for at least 25 minutes. If you're short on time and want to skip soaking them, you can go ahead and directly add cleaned dehydrated mushrooms to any dish that you know will need to be cooked for at least 25 minutes.

What enhances the flavor of mushrooms? ›

What is the secret to cooking mushrooms? ›

Turn up the heat: Turn the heat up to medium-high and allow time for your oil/butter to get hot before adding the mushrooms.

Achieve Golden Perfection: Continue to cook and stir the mushrooms until they turn golden brown, adjusting the heat as needed.

Do mushrooms need to be cooked before putting on pizza? ›

What is the best way to eat oyster mushrooms? ›

Serve as a side dish or use in sauces, stir-fries, pastas, risotto, or even to top toast. Because they get so silky when cooked, oyster mushrooms respond well to braising, too. Add them to soups and stews or sauces.

Do you eat the stems of oyster mushrooms? ›

These tasty stems add texture and depth to your dishes, allowing you to enjoy the whole mushroom with every delightful bite.

How do you fry mushrooms without them getting soggy? ›

Instead of tossing the mushrooms straight in the pot, cook them in a little skillet alongside before you add them. This will help release their moisture, concentrate their natural sugars right in the pot, and lend big flavor to the whole dish.

Should you soak mushrooms before frying? ›

Since it's clear that there's nothing wrong with soaking mushrooms, that's the way many clean them, being a fast and thorough process. If you've got a colander that fits into a bowl, you can place the mushrooms in the colander, put it into a bowl in the sink, and fill with water.

How do you keep mushrooms from getting watery when frying? ›

Use the widest pan you can to maximize evaporation while you fry them, also, you can put them in a very low oven for an hour to draw some of the moisture out. Don't crowd the pan, make sure each one has some space. Also, don't wash them in water before cooking! Mushrooms are sponges, they absorb liquids.
