Ingredients for Creamy Potato-Leek and Cauliflower Soup

Butter adds a rich flavor base and helps to sauté the leeks without browning them too much. Olive oil complements the butter and prevents it from burning, adding a hint of fruity aroma. Leeks are the star here, offering a subtle onion-like flavor that mellows and sweetens when cooked. Garlic provides a fragrant depth that's essential in soups. Chicken or vegetable broth forms the foundation, giving the soup its body and richness. Russet potatoes make the soup creamy when pureed, and their starch helps thicken it naturally. Cauliflower adds another layer of creaminess and a hint of nuttiness. Heavy cream enhances the soup's velvety texture. Dried thyme adds an earthy aroma that pairs perfectly with the leeks and potatoes. Salt and pepper bring all the flavors together. Finally, chopped chives provide a fresh, vibrant finish.

Tips & Tricks

  • If you don't have an immersion blender, carefully transfer the soup in batches to a regular blender.
  • For a lighter version, substitute half of the heavy cream with milk or use a non-dairy alternative.
  • Clean your leeks thoroughly; they can be sandy. Slice them first, then rinse under running water.

Serving Suggestions

This soup pairs beautifully with crusty bread or garlic toast. For a heartier meal, serve it alongside a crisp green salad with a tangy vinaigrette.

Frequently Asked Questions

Can I make this soup ahead of time?
Yes, this soup can be made a day in advance and stored in the fridge. Just reheat gently on the stove before serving.
Is this soup freezable?
While you can freeze it, the texture may change slightly upon reheating due to the cream. For best results, freeze without the cream and add it in after reheating.
