Run dried mushrooms through blender or food processor to transform them into a chunky powder.
Meanwhile, in a medium sized pot, heat chicken broth and over low heat. Add powdered dried mushrooms.
In a medium sized heavy bottom stockpot or dutch oven, melt butter and saute mushrooms, onion, and garlic over medium high heat until lightly brown, 10-15 minutes.
Add rice and stir for 1 minute. You want rice to get slightly browned.
Add wine and stir until liquid is absorbed, approximately 2 minutes.
Add ½ cup of stock (I just use one ladle full) and continue stirring until liquid is absorbed. Continue to add stock mixture, ½ cup at a time, stirring until liquid is absorbed, until all liquid has been added to rice, approximately 30 minutes.
Turn off heat. Stir in grated shredded cheese, and salt and pepper to taste. Stir to combine and allow to rest. Serve hot.
