To keep portobello mushrooms from getting soggy, pre-bake them for 3 to 4 minutes before stuffing.
Instructions

FAQ
To prepare portobello mushrooms, remove the stems, gently scrape out the gills with a spoon, and wipe the caps clean with a damp cloth.
While it’s not required, removing the gills helps prevent excess moisture and ensures the filling stays flavorful and firm.
To avoid sogginess, pre-bake the mushrooms for a few minutes before stuffing, and avoid overloading them with watery ingredients.
Yes! You can prepare the mushrooms and prep the ingredients in advance and store them in the refrigerator. Just scramble the eggs and bake when ready to serve for a quick and easy meal.
