Oven Roasted Mushrooms with Herbs

One of my favorite nutritious sides is a hefty serving of oven roasted mushrooms made with homegrown herbs and good quality olive oil.

In the winter I tend to use dried Italian seasoning that can be found in supermarkets, but I’ll use homemade Fresh Italian Seasoning for the rest of the year.


  • Only 5 ingredients
  • Deliciously juicy mushrooms

  • Easy to make
  • Filling and healthy
  • Can be made with any variety of mushrooms

Fresh Italian Seasoning

For incredible flavor, I love to season these mushrooms with a generous amount of smoked salt. Alderwood smoked salt is my favorite, but you can use any variety of smoked sea salt, or just regular sea salt if you can’t find any. The fresh herbs are a combination of chopped fresh thyme, oregano, parsley, and rosemary. You can play around with the ratios according to your taste. Do you love rosemary? Use more of it! Can’t stand oregano? You’re allowed to omit it!

As for what kind of mushrooms to use, use whatever mushrooms are available to you. The most commonly sold ones in the States are baby bellas and white mushrooms. When available, I like to be creative and use locally grown or specialty mushrooms such as oyster mushrooms and lion’s mane. You can also use shiitake mushrooms, porcini, or cremini.
