Balsamic Marinated Mushrooms in a baking dish

 

Ingredients for Balsamic Marinated Mushrooms

Balsamic Marinated Mushroom ingredients including mushrooms, olive oil, balsamic vinegar, garlic, salt, pepper, nutmeg, and oregano

There are only a few ingredients involved in making these yummy mushrooms.  First choose your favorite 16-ounce package of white, baby Bella, or cremini mushrooms.  When selecting your mushrooms, if you can find a package that has a consistent size of mushrooms, that is best for even roasting.

 

Did you know that white button mushrooms, cremini and baby Bella are actually all the same type of mushroom but at different phases of maturity? You can use them interchangeably to your preference! There is a slightly different flavor for each, so it’s all about what you love.

For this recipe, you will also need 2 cloves of fresh garlic, olive oil, onion powder, nutmeg, oregano, salt, pepper, and balsamic vinegar. If I have fresh oregano, I will definitely use that instead of dried.

How to Prepare these Balsamic Marinated Mushrooms

First, you will need to wash the mushrooms.   I like to use a damp paper towel or mushroom brush to clean the mushrooms, so that they do not absorb to much moisture.  Then, trim the stems.  If the mushrooms are large, I quarter them. If my package has unevenly sized mushrooms, I cut the larger mushrooms and leave some of the smaller ones whole.

Preheat the oven to 400°.  Next, put all of the washed and cut mushrooms into a medium bowl.  Add 1/3 cup olive oil, 2 pressed garlic cloves, 1 tsp onion powder, 1 tsp nutmeg, 1 tsp dried oregano (or 1/2 tsp fresh chopped oregano leaves), 1/4 tsp salt, and 1/4 tsp ground pepper. Mix all of the spices and olive oil to coat the mushrooms evenly.

Pour the seasoned mushrooms into a small baking dish.  They do not need to be in a single layer as they will shrink a good amount when roasting.  Roast the mushrooms for 25 minutes.

Once cool, cover the container and place in the refrigerator for 2-24 hours. Drain and enjoy whenever!

Serving Suggestions

  1. We love these mushrooms as a side with just about any grilled meat, such as this Grilled Tri-Tip.  Also, add them to a Greek Chicken Bowl or salad for a pop of flavor and variety in texture.
  2. Serve warm with grilled meats and chilled on a salad OR room temp for either….or just for snacking on.  Other complementary side dishes would include these Roasted Mini Potatoes.
  3. My favorite baking dish to roast these balsamic marinated mushrooms is the small or medium Staub brand baking dish.

Did you know that mushrooms are an excellent source of low calorie and immune boosting nutrients? According to Healthline , mushrooms are packed with Vitamin D and B, antioxidants, as well as minerals that support cell health in many body systems.  It is true that mushrooms do lose some of their vitamin D content in the cooking process, however, they are still packed with goodness.
