Ingredients

Scale

Vegetables

  • 3 leeks, cleaned and chopped
  • 1 small yellow onion, diced
  • 2 garlic cloves, chopped
  • 2 ½ cups chopped cauliflower

Other Ingredients

  • 3 ½ cups vegetable broth
  • ¾ cup white beans, drained
  • 3 fresh thyme sprigs
  • Salt & black pepper, to taste
  • 12 tablespoons oil or butter, for sautéing

Instructions

  1. Prepare the vegetables: Remove the ends and outer layers of the leeks, slice them lengthwise in half, and dice into small pieces. Rinse the diced leeks thoroughly in a bowl of water to remove any dirt. Dice the yellow onion and chop the garlic cloves finely.
  2. Sauté vegetables: Heat oil or butter in a large pot over low to medium heat. Add the diced leeks and onions, sprinkle a pinch of salt, and sauté for about 5 minutes until softened. The salt helps draw out moisture and intensifies flavor.
  3. Add aromatics: Stir in the chopped garlic and fresh thyme sprigs, cooking for another 30 seconds to release their fragrance and deepen the soup’s flavor profile.
  4. Add rest of ingredients & simmer: Add the chopped cauliflower, vegetable broth, white beans, and season with salt and black pepper. Cover the pot and let the mixture simmer gently for 12 to 15 minutes until the cauliflower is tender. Remove the thyme sprigs using a fork.
  5. Puree soup: Carefully transfer the soup in batches to a high-powered blender or use an immersion blender directly in the pot to puree until smooth and creamy.
  6. Taste and serve: Taste the soup and adjust seasoning as needed. Add extra salt to enhance flavor or a pinch more black or red pepper for some heat. Serve hot and enjoy!

Notes

  • When cleaning leeks, it’s important to rinse them well as they often contain dirt between the layers.
  • Using white beans adds natural creaminess and protein without dairy.
  • You can substitute thyme with rosemary or sage if desired.
  • For a richer texture, add a splash of plant-based cream or milk after pureeing.
