  • Wipe and dry the mushrooms and cut in half and thickly slice.
  • Beat together the eggs in one bowl.
  • Mix together the rest of the ingredients in another (panko breadcrumbs, salt, pepper, onion and garlic powder).
  • One by one, dip each piece of mushroom in the egg to coat, then fully cover with the panko mixture. Place on a lined baking sheet and repeat with all pieces.
  • Heat a few sups of oil in a heavy bottomed pan or Dutch oven. You want to put enough in so that the mushrooms float in the oil and not touch the bottom of the pan.
  • Heat the oil on a high heat. Test the heat by dropping in a couple of breadcrumbs, if they sizzle, the oil is hot enough.
  • Place 4 pieces of the breaded mushrooms in the oil. Cook for a few minutes til golden brown, using tongs to flip the pieces over to brown all over. Place onto a lined baking sheet and repeat until all of the mushrooms are cooked.


  • Cut the mushrooms fairly thick to make the most of their meaty texture.
  • Use a large heavy bottomed pot or Dutch oven for the frying. It will help to keep the oil at a consistent temperature.
  • Make sure that the oil is hot before adding in the mushrooms. Drop a couple of panko breadcrumbs into it, if they sizzle, you are good to go.
  • Fry the portobello mushrooms in batches. If you add too many at a time the temperature of the oil can drop. Give them room to brown all over.
