  • 6 medium sweet onions
  • 1 whole garlic bulb
  • 3 cups reduced-sodium chicken broth, divided
  • 1/2 cup buttermilk
  • 1 tablespoon minced fresh thyme or 1 teaspoon dried thyme
  • 1/2 teaspoon coarsely ground pepper
  • 1/2 cup shredded Swiss cheese


  1. Place the unpeeled onions and garlic bulb in a 15x10x1-in. baking pan coated with cooking spray. Spritz with cooking spray. Bake, uncovered, at 450° for 50-60 minutes or until tender.
  2. When cool enough to handle, peel the onions and garlic. Place in a blender; add 1 cup of broth. Cover and process until smooth; transfer to a large saucepan. Add the buttermilk, thyme, pepper and remaining broth; heat through. Garnish with cheese.
