Remove the stems, a twist off should do the trick.

- With a spoon, gently scrap the gills until you see the white.

- With a damp paper towel, gently clean them.

- Cut them in little sticks

- In a small bowl, beat the egg and in another bowl; place the crumbs.

- Take one mushroom stick, cover it with egg and then cover it with crumbs.

- Place it on the baking sheet covered with parchemin paper

- Repeat until you have used all your mushroom sticks

- Drizzle with olive oil

- Bake 10-12 minutes in the oven at 350F.

Notes

I did not put any salt in the recipe because the bread crumbs are already salty enough with the parmesan.
