1 large head fresh garlic
2 T. olive oil
2 cups chopped yellow onion
1 bunch. finely chopped fresh flat-leaf parsley
1/2 T. finely chopped fresh thyme
15 peeled garlic cloves
4 cups low-sodium vegetable stock, divided
2 T. fresh lemon juice
1/2 cup milk,
2-3 Tablespoon dark soy sauce
Freshly ground black pepper, to taste
Sprigs of fresh parsley and lemon zest, for garnishing
1. Preheat the oven to 350 F. Drizzle the garlic head with olive oil, wrap with foil and place in the oven for 1 hour, or until lightly golden and very soft and fragrant. Let garlic cool until it can be handled. Using your fingers, gently squeeze the cloves to release them from their skins into a bowl, and set aside. Discard the skins.
2. In a medium-sized heavy-bottom stock pock or saucepan, heat the olive oil over medium high heat. Add the onions, parsley and thyme and cook until the onions are just softened, about 3 minutes. Add the fresh and roasted garlic, and cook, stirring often, until the onions are translucent, about 3-4 minutes more. Add the vegetable stock and lemon juice, turn down the heat and let the soup simmer, covered, for 35-40 minutes, or until the garlic is very tender.
3. Working 1-2 cups at a time, process the soup in a blender, transferring the soup to another bowl or saucepan. (Note: be careful not to overwhelm the blender; never fill a blender with hot liquid more than half-way full and make sure the lid is on securely before processing.)Transfer the pureed soup to the saucepan, milk and salt, and return the mixture to a simmer. (Do not bring to a boil.)
4. Add additional salt and pepper to taste, garnish with fresh parsley and lemon zest, and serve.
