Creamy, comforting slow cooker soup with tender leeks and Yukon Gold potatoes. Easy hands-off recipe perfect for spring.

Ingredients

Scale
  • 2 tablespoons butter or olive oil
  • 3 large leeks (about 3 cups sliced), white and light green parts only
  • 3 cloves garlic, minced
  • 6 medium Yukon Gold or Russet potatoes (about 2 pounds), peeled and diced
  • 5 cups vegetable or chicken broth
  • 1 teaspoon dried thyme
  • 1 teaspoon salt, plus more to taste
  • ½ teaspoon black pepper, plus more to taste
  • 1 cup heavy cream or full-fat coconut milk
  • 1–2 tablespoons fresh lemon juice (from ½ lemon)
  • Chopped chives and Parmesan for garnish

Instructions

  1. Heat butter or olive oil in a skillet over medium heat. Add sliced leeks and minced garlic, then sauté for about 5 minutes until soft and fragrant.
  2. Transfer sautéed leeks and garlic to slow cooker. Add diced potatoes, broth, dried thyme, salt, and pepper. Stir to combine all ingredients.
  3. Cover and cook on LOW for 6-8 hours or HIGH for 3-4 hours until potatoes are very tender and break apart easily.
  4. For smooth soup, use an immersion blender to puree directly in crockpot until creamy. For chunkier texture, mash some potatoes with a fork while leaving others whole. For perfect texture, blend two-thirds smooth and leave one-third chunky.
  5. Stir in heavy cream or coconut milk and fresh lemon juice. Cook for another 5 minutes on LOW until heated through and flavors meld.
  6. Taste and adjust seasoning. Ladle into bowls and garnish with fresh chopped chives and grated Parmesan or crumbled feta. Serve with crusty bread for dipping.

Notes

  • Clean leeks thoroughly as dirt can hide between layers. Slice lengthwise and rinse well.
  • Yukon Gold potatoes create naturally creamy texture. Use about 2 pounds total.
  • For dairy-free version, use olive oil and full-fat coconut milk.
  • Freeze before adding cream for best texture when reheating.
  • Can sauté leeks night before and refrigerate until ready to use.
