Ingredients Needed for This Portobello Mushrooms Recipe

The simple ingredients is a starting point. Check our flavor variations to try below.

Portobello Mushrooms

If you can, purchase mushrooms from the bulk bin—that way you can choose the freshest mushrooms. When buying mushrooms, steer clear of any mushrooms that are moist or slimy. Mushrooms should be mildly damp and springy, they should not be mushy or spongey.

Olive oil

I prefer extra-virgin olive oil for its flavor, but you can also use avocado oil or vegetable oil. 

Kosher salt and Black Pepper

I prefer kosher salt in cooking but sea salt will also work well here. If you like things spicy, consider using cayenne or red pepper flakes instead of black pepper. 

Step-By-Step Instructions To Roast Portobello Mushrooms

A few simple steps in this portobello mushroom recipe are key to perfectly juicy results:

• Last: Flipping and finishing them upside down for a just a few minutes to sear and finish them off before serving
