  • 1 Tbsp. olive oil
  • 5 large onions, peeled and chopped
  • 4 cloves garlic, minced
  • 1 tsp. sugar
  • ½ cup dry red wine
  • 4 carrots, sliced
  • 4 cups beef stock
  • 4 cups chicken stock
  • ½ tsp. salt
  • ⅛ tsp. ground white pepper
  • ½ tsp. dried marjoram leaves
  • 1 package (3 oz.) low-fat cream cheese, softened
  • 1 cup shredded Havarti cheese
  • 2 Tbsp. grated Parmesan cheese
  • 8 slices crusty bread
  • ⅛ tsp. ground black pepper


  • In 4- to 5-quart slow cooker, combine olive oil, onions, garlic, and sugar. Cover and cook on high for 2 hours, stirring occasionally, until the onions are deep golden brown. Halfway through cooking time, add the red wine. Do not let this burn.
  • Add carrots, beef stock, chicken stock, salt, white pepper, and marjoram. Cover and cook on low for 4 hours. Meanwhile, in small bowl, combine cream cheese, Havarti, and Parmesan cheeses.
  • Preheat broiler. Spread cheese mixture on bread slices and sprinkle black pepper over top. Broil bread slices until cheese melts, about 3 minutes. Spoon soup into hot bowls and top with bread.
