Crispy Roasted Mushroom Nutrition

Generally, mushrooms are a good source of potassium and iron. For this recipe, 8oz of mushrooms can contribute to three servings. Each serving has 144 calories, so this recipe is generally low in calories. A main contributor to fat here is olive oil, however, the olive oil is full of mono and poly-unsaturated fats, which are great for brain health. Because this recipe contains now animal products, it is cholesterol free. Low in carbohydrates, crispy roasted mushrooms have less than 4 carbs per serving. Due to its small serving size, the fiber content is less than 1g per serving. I recommend eating this meal with a fiber rich green like kale or spinach or a whole grain.

Food science tips: Crispy Roasted Mushrooms

Mushrooms can be super polarizing because of their texture. Mushrooms are composed of 80-90% water. If the water is not fully expelled from the mushrooms during the cooking process, the remaining water inside the mushrooms creates a slimy texture. Because of the high water content, it’s recommended to store mushrooms refrigerated and not frozen. The high water content will cause ice crystals to form within the filaments and alter the texture when thawed. 

Because of the high moisture content, the recipe for crispy roasted mushrooms has some essential components that should not be changed.  For example, salt is critical to help drive out the mushrooms’ moisture during cooking. Removing salt will prolong your cooking period, using more energy during the cooking process.

A second example is the higher temperature in the oven. Some recipes recommend 350F for roasting; however, this will only prolong the cooking process and leave you lacking the quintessential characteristic of crispy roasted mushrooms!

You can season the mushrooms with anything you’d like, but we recommend cremini mushrooms. Different mushrooms have different flavor profiles, so I would not say this recipe is the optimal “one size fits all” mushroom seasoning for all fungal varieties. 

This will provide you with a delectable texture for crispy roasted mushrooms. You will know when the mushrooms are finished cooking when there is no more moisture around the outside of the mushrooms on the baking sheet, as seen below.

Time Saving Tip

In just under an hour, crispy roasted mushrooms are ready in under an hour with minimal prep time. If you decide to buy your mushrooms pre-sliced, you’re already saving a significant amount of time.
