Sauté the fresh mushrooms with a clove of garlic for 10 minutes.
Add salt and turn the fire off.
If you use dried mushrooms, soak them for about half an hour in warm water.
Remove them from water, squeeze them lightly and place them on kitchen paper.
Filter and keep soaking water aside.
Heat oil in a non-stick pan, add the finely chopped shallot and cook for 10 minutes.
Toast rice for 3 minutes then add it to the shallot.
Pour 1 ladle of hot broth on rice, gradually adding more as it is absorbed. If you are using dried mushrooms add their soaking water.
Add mushrooms a few minutes before rice is ready.
The final step is to add Parmigiano Reggiano.
Place on a plate, sprinkle with chopped parsley and drizzle with extra virgin olive oil.
