  • 1 large head cauliflower, cut into florets (10 cups)

  • 1 large onion, sliced

  • 2 cloves garlic, halved

  • 2 tablespoon olive oil

  • 2 14.5 ounce cans chicken broth

  • 1 cup water

  • 1 bay leaf

  • 1 teaspoon snipped fresh thyme or 1/4 teaspoon dried thyme, crushed

  • 1 cup half-and-half or light cream

  • 1 teaspoon salt

  • teaspoon ground black pepper


  1. Preheat oven to 400°F. In a large roasting pan combine cauliflower, onion, and garlic. Drizzle with oil; toss gently to coat. Spread vegetables in an even layer. Roast, uncovered, for 30 minutes, stirring once.

  2. In a 4-quart Dutch oven combine roasted vegetables, broth, the water, bay leaf, and thyme. Bring to boiling; reduce heat. Simmer, covered, for 20 minutes; cool slightly. Remove and discard bay leaf.
