How Long To Grill Portobello Mushrooms (And Why)?

Exact Answer: 3 To 4 Minutes On Each Side

Grilling is a great way to add some flavor and texture to the favorite mushrooms. A great example, grilled portobello mushrooms are delicious on their own or as part of an entree with rice, pasta, or vegetables. 

If one grills them too quickly, then the outside will be charred while the inside will still be raw. One can also grill other vegetables like asparagus or zucchini alongside the mushrooms if one likes until it’s tender on each side. Grill them whole or slice them into large pieces first, depending on how one uses them later.
