When I was a child, my mother made potato and onion soup because it was affordable and fast. I’ve trimmed the calories, but it’s still a comforting family favorite. —Courtney Stultz, Weir, Kansas

  • 1 medium leek
  • 1-1/2 pounds potatoes (about 2 large), peeled and finely chopped
  • 2 cups fresh cauliflowerets
  • 3/4 teaspoon rubbed sage
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 4 cups reduced-sodium chicken or vegetable broth
  • 2 teaspoons olive oil
  • 2 teaspoons lemon juice
  • Sour cream, optional


  1. Finely chop white portion of leek. Cut leek greens into thin strips; reserve for topping. In a 3- or 4-qt. slow cooker, combine potatoes, cauliflowerets, seasonings, broth and chopped leek. Cook, covered, on low 6-8 hours or until vegetables are tender.
  2. In a small skillet, heat oil over medium-high heat. Add reserved leek greens; cook 3-5 minutes. Puree soup using an immersion blender. Or cool soup slightly and puree in batches in a blender. Stir in lemon juice. Top with leek greens and, if desired, sour cream.
