This Week’s Vegetable Box Feature: Portobello Mushrooms

Did you know?

  • They are of Italian origin and gets its namesake from Portobello, a town in Italy.
  • They have a wonderfully earthy flavor that is often times described as meaty. They taste similar to cremini mushrooms or button mushrooms, but have a richer and more intense umami flavor.
  • They make a fabulous meat substitute in vegetarian and vegan dishes because of their meaty flavor and thick, dense texture.
  • They are full of great plant compounds like B vitamins, potassium, selenium, and copper.


What's the difference between a portobello mushroom, cremini and a button mushroom?

They are literally the same type of mushroom. They are all Agaricus bisporus, in fact, just different ages: button mushrooms, which are white, are the toddlers; cremini mushrooms, which are brown, are the teenagers; and portobellos, which are brown and much larger versions of their younger selves, are the adults.


How to Store Them?

Store them in a paper bag in the refrigerator for up to seven days. You can also wrap them in a paper towel and store them in a tupperware container in the refrigerator.


How to Prepare them:

Cleaning: Don't wash a portobello mushroom until right before you prep them for eating or cooking. When ready, wash them well under running water, removing all the dirt from the cap and running your fingers through the gills.

Prepping: Either trim the cap or pop it off completely and pat the mushroom dry.

Peeling: In some cases, you may want to peel the top layer of the cap! If cooking the mushroom caps whole, its found that peeling creates a better texture for portobello burgers and portobello steaks.


How to Use Them? Can you enjoy the whole mushroom?

The stems of large portabella, while technically edible, can be woody and fibrous and are usually discarded (or used to flavor stock). Likewise, the dark black gills can be eaten, but they'll turn your food a nasty, murky, scuzzy brown, so most like to scrape them out. Portabello mushrooms are best enjoyed cooked!


A few favorite ways to prepare portobello mushrooms:

Whole mushroom caps: These are wonderful as burgers, steaks, or even stuffed!

Sliced: Perfect for sautéing mushrooms and serving with pasta, stir fry, or a simple side dish.

Diced: Adds amazing flavor to soups and casseroles.
