Crock-Pot French Onion Soup, Skinny Style

French onion soup is a bistro classic. I’ve been a huge fan of this main course soup for years but rarely order it, since it’s usually very high in fat. My skinny version is so hearty and much lower in fat. Although it’s a crock-pot recipe, it takes a few minutes of prep work before adding all the ingredients to the crock-pot. What results is a rich-tasting soup, chock full of melt-in-your-mouth onions. And, each bite includes some of the garlic toast. Each main course bowl, including the garlic toast, has 355 calories and 8 grams of fat.

Ingredients for Soup:

  • 4-5 large onions, sliced (15 cups total, sliced)
  • cup  reduced-fat butter
  • 2 tablespoons Worcestershire sauce
  • ¼ cup water, if needed
  • 2 teaspoons garlic cloves, minced
  • 1 cup red wine, any kind
  • 1 tablespoon Worcestershire sauce
  • Black pepper, to taste
  • 2 bay leaves
  • 1 teaspoon dried thyme
  • 8 cups reduced-sodium beef broth
  • 6 teaspoons Parmesan cheese, grated, for topping

Ingredients for Garlic Toast:

  • 6 slices of multigrain or whole wheat bread, I used Milton’s multi-grain
  • 6 teaspoons reduced-fat butter
  • 6 teaspoons Parmesan cheese, grated
  • 3 teaspoon garlic powder


  • Add onions to a large, microwave-safe bowl. Cook in microwave for 5-6 minutes, until soft.
  • In a large nonstick pan, melt butter over medium heat. Add onions and 2 tablespoons of Worcestershire sauce. Sauté over medium to med-high heat until caramelized and tender (about 8-10 minutes). If pan gets too dry add a little water. Stir often and continue to add a little water, if needed. Add garlic and cook 2 minutes more.
  • Pour onions from pan into crock-pot. Stir in wine and 1 tablespoon Worcestershire sauce. Add black pepper, bay leaves, and thyme. Stir in beef broth. Mix well.
  • Cook on High heat for 4 hours or low heat for 7-8 hours.
  • Just before serving, prepare the garlic toast. Toast each slice of bread. Spread each with 1 teaspoon butter. Sprinkle each with 1 teaspoon Parmesan cheese and ½ teaspoon garlic powder.
  • For each serving: Add 1¼ cups soup to each bowl. Sprinkle top of each with 1 teaspoon of Parmesan cheese. Place garlic toast on top and serve.
  • This soup freezes great! Make the garlic bread after it’s defrosted and heated.
