Heat 1 tablespoon of olive oil in a pan and cook the mushrooms with the whole garlic garlic. When the mushrooms are cooked, remove the garlic and set aside the mushrooms.
Add another tablespoon of olive oil in the same pan and sauté the chopped onion until transparent. Add the rice and toast it for 2-3 minutes.

Serve hot, and enjoy the creamy mushroom risotto!
