For pesto: In the container of a blender, place parsley, oil, 3 tablespoons water, lemon zest and juice, garlic, and salt; process until smooth. Set aside.
For bisque: In a large Dutch oven, cook bacon over medium heat until crisp. Remove bacon using a slotted spoon, and let drain on paper towels, reserving 2 tablespoons drippings in pot.
Add onion to Dutch oven; cook until translucent and beginning to caramelize, about 30 minutes.
Add garlic to pot; cook for 5 minutes, stirring constantly. Add broth, vinegar, thyme, rosemary, salt, and ½ teaspoon pepper; bring to a boil. Reduce heat, and simmer for 30 minutes, stirring occasionally.
Remove from heat; let cool for 30 minutes. Discard thyme and rosemary sprigs. Using a handheld blender, purée soup until smooth. Drizzle pesto over soup servings. Sprinkle with bacon, goat cheese, and remaining ½ teaspoon pepper. Serve with Woodland Cheese Branches.
