2-1/2 pounds Yukon Gold potatoes, peeled and quartered
2 cups chicken broth, divided
1/4 cup butter, softened
1/4 teaspoon pepper
1/8 teaspoon salt
Remove papery outer skin from garlic bulb (do not peel or separate cloves). Cut top off bulb; brush with oil. Wrap in heavy-duty foil. Bake at 425° for 30-35 minutes or until softened. Cool for 10-15 minutes.
Meanwhile, place potatoes in a large saucepan and cover with water. Bring to a boil. Reduce heat; cover and cook for 15-20 minutes or until tender.
Place 1 cup broth in a blender. Squeeze softened garlic into blender; cover and process until blended. Drain potatoes; place in a large bowl. Add the butter, pepper, salt, garlic mixture and remaining broth; beat until smooth.
