How to Make Stuffed Portobello Mushrooms

Step 2: Prepare the Mushrooms
Brush both sides of the mushrooms with olive oil. Place them gill-side up on the prepared baking sheet. Season lightly with salt and pepper.

Spoon the filling evenly into each mushroom cap. Don’t forget to sprinkle shredded mozzarella cheese generously on top for that melty finish!

- Not seasoning adequately: Under-seasoning can result in bland flavors. Be sure to taste your filling and add salt, pepper, or herbs as needed before stuffing.
- Ignoring cook times: Baking the mushrooms for too long can make them tough. Keep an eye on them and remove them from the oven when they’re tender and the cheese is bubbly.
