Preheat oven to 375ºF.
Slice 1/4 of an inch off the top of the garlic bulb, exposing the top of all cloves. Place garlic onto a small piece of aluminum foil and drizzle with EVOO. Enclose garlic in a small pouch and roast in oven until cloves are deep golden brown, about 45 minutes. Remove from oven and cool.
Squeeze roasted garlic cloves out of bulb and into a medium mixing bowl. Mash into a paste with a fork. Add breadcrumbs, parsley, thyme, some salt and pepper to bowl, and stir to combine. Reserve.
Place a large pot of water over high heat to boil water. When water comes up to a full boil, season with salt. Drop macaroni and cook to al dente according to package directions. Drain cooked pasta and reserve in pot it was cooked in.
