Pro tips
- Since you don’t want the mushroom cap to get soggy when baking, cooking them on a perforated pizza pan allows the moisture to escape
- You will want to remove the stems from the mushroom and the gills. These are the little flaps the surround the inside of the mushroom cap. They are 100% edible, but you might find that they taste a little earthy, so remove them at your discretion!
- If you choose to add any meats to your pizza, be sure it is thoroughly cooked first as there won’t be enough time for meat to cook in the mushroom cap (in this recipe)
- Wondering what kind of mushrooms work best for this recipe? You are looking for large portobello mushrooms. They are often bundled up into pairs, and also sold individually. Try to find the biggest ones you can so you can fit all the great pizza fillings
