½ cup freshly grated Parmigiano-Reggiano, plus more for serving
Coarse salt & ground pepper, to taste
Instructions
Preheat oven to 375 degrees.
Drizzle garlic heads with olive oil. Wrap tightly in parchment paper, then foil & put in oven (I put these on a cookie sheet & then put them in the oven). Roast garlic for 40 minutes. Let cool then squeeze the cloves from the papery skins.
Over medium heat, bring vegetable stock, potatoes & roasted garlic to a boil in a medium saucepan.
Reduce heat & simmer until potatoes are tender, about 12-15 minutes. Remove from heat & stir in cheese.
