Baked Portobello Mushrooms

Baked portobello mushrooms are QUICK and EASY to prepare in less than 30 minutes, and are full of flavor from butter, thyme, and a cheese topping! They’re meaty enough to satisfy any carnivore and versatile enough to be a main dish or side.

Portobello mushrooms are larger in size than common white mushrooms, which makes them very versatile. They’re great for stuffing, and you can even use them in place of burger patties or buns. A classic favorite, though, is simple baked portobello mushrooms. Baking  Portobello Mushrooms really brings out the best in their wonderful flavor.

Portobello or portabella?

Portobello and portabella are one and the same! You can call them portobello mushrooms or portabella mushrooms; neither spelling is incorrect.

How to clean Portobello Mushrooms

As with other mushrooms, ideally, you want to wipe portobello mushroom caps rather than wash them to clean them.

Mushrooms can become mushy if they get too wet, so wiping them down is the best way to clean them. If any parts of the skin are particularly damaged, you can peel a section back.

For these baked portobello mushrooms, I’d suggest removing the stem and wiping them clean with a damp paper towel. Some other uses may require removing the gills with a spoon as well, for a drier mushroom after cooking.
