Portobello or portobella?
Portobello and Portobella can be used interchangeably in this delectable portobello mushroom recipe. Neither spelling is incorrect!
What is the difference between Portobello and regular mushrooms?
Button, cremini, and portobello are actually all the same – they’re just at different stages of growth! They are all a part of the “agaricus bisporus” family.
Portobello are fully grown button mushrooms and are large, making them perfect for stuffing.
Cremini are somewhere in-between. You will even find cremini sold as baby bellas!
How to Clean Portobello Mushrooms
Mushrooms should always be wiped clean rather than rinsed. Many oven baked portobello mushroom recipes remove the gills, but in this case, we leave the gills intact for extra flavor and juiciness.
- Start by removing the stem. Just trim it with a knife or twist it off. Tip: you can keep the stem to chop up for the stuffing instead of tossing it.
- Dampen a paper towel. You can also use a mushroom cleaning brush (this one is cute!).
- Gently scrub the cap with the paper towel to clean the outside. You may also want to scrub the gills, but don’t remove them.
Don’t rinse them – they absorb water quickly and can become mushy!
🧾 Variations
- Replace the garlic and butter with our herby Garlic Butter Spread.
- Try your favorite cheeses. Fontina and gruyere are excellent choices.
- Add an extra protein if you like. Shrimp stuffed portobello mushrooms in the oven are delicious!
- Mix in caramelized onions or sauteed spinach for even more flavor.
What to serve with Oven Baked Portobello Mushrooms
