Oven Roasted Oyster Mushrooms are made just with 5 simple ingredients: Oyster mushrooms, salt, pepper, rosemary and olive oil. The most amazing flavor combination! You end up with the tastiest vegan snack ever! What’s more, they make a great touch on soups or in salads.
Oyster mushrooms are our favorite type of mushrooms. They have an outstanding flavor and we love creating recipes with them. If you love them too, you should see our pan fried oyster mushrooms, oyster mushroom noodle soup and sauteed oyster mushrooms with peppers.
These oyster mushroom chips are one of the best vegetable snacks ever! Turning a vegetable into a chips is like a magic in the kitchen. A perfect way to include vegetables in your diet. Some other veggie snacks we love are okra chips, zucchini chips and fried green beans.
It is an easy recipe with 5 ingredients:
- Mushrooms (we use oyster, but any mushroom works fine)
- 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 30 minutes or until brown and crispy.
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.
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.
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.
If the mushroom is firm and dry, it is fresh and good. If it is slimy and too soft, it is bad.
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.
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.
