How to Prepare Stuffed Portobello Mushrooms
Step-by-Step Instructions
- Cleaning the Mushrooms: Wipe your Portobello mushrooms gently with a damp paper towel. Remove the stems and scrape out the gills using a spoon. Be careful not to break the caps, as theyβll hold your stuffing.
- Preparing the Stuffing: For a veggie-filled stuffing, sautΓ© your vegetables in olive oil until soft. For meat-based stuffings, cook your meat first, then add vegetables and seasonings. Combine everything with your choice of cheese, herbs, and optional grains for a complete filling.
