Instructions

  1. In a large saucepan heat olive oil over medium-low heat. Cook onion and leeks in hot oil, covered, for 13 to 15 minutes or until onions and leeks are tender, stirring occasionally. Uncover; stir in brown sugar. Cook and stir over medium-high heat for 4 to 5 minutes more or until onions and leeks are golden brown.
  2. Stir mushrooms and carrots into onion mixture. Cook and stir over medium heat about 3 minutes or until mushrooms are tender. Stir in chicken broth, the 1-3/4 cups beef broth, cooked rice, sherry (if desired), and pepper.
  3. In a screw-top jar combine the 1/2 cup cold water and flour. Cover and shake until smooth; stir into the soup mixture. Cook and stir until slightly thickened and bubbly. Cook and stir for 1 minute more. Makes four 1-3/4-cup servings.
