Easy Cheese Pizza

Preheat oven to 350 degrees F. Slice off top of garlic head to reveal cloves and drizzle with 1 teaspoon olive oil. Wrap garlic with aluminum foil, place in upper third of oven, and roast until cloves are easily pierced with a sharp knife, about 50 minutes. Remove from oven and set aside. Meanwhile, combine flour, yeast, rosemary, sugar, and salt in the bowl of a food processor fitted with the metal blade. In a separate bowl, combine milk, 3 tablespoons olive oil, and water and add in a stream with processor running until dough forms. Transfer to a lightly floured surface and knead until smooth and pliant, about 6 minutes. Coat the inside of a large bowl with olive oil, form dough into a ball, and roll it around bowl. Cover bowl loosely with plastic wrap and a kitchen towel. Let dough rise until doubled in volume, about 1 hour. Increase oven to 375 degrees F. Punch down dough and roll out on a lightly floured surface to fit into a 12-inch-round pizza pan or a baking sheet. Cover and let rise for 15 minutes. Mix sauce and 2 tablespoons parsley together. Squeeze roasted garlic cloves onto pizza and spread, leaving a 1/2-inch border. Top with sauce mixture, sprinkle on cheese, and bake 25 to 30 minutes. Garnish with remaining 2 teaspoons parsley.
