Ingredients
- olive oil
- 2 medium leeks, halved and thinly sliced reserve the leek greens for the topping
- 4 garlic cloves, minced
- 1 teaspoon dried thyme
- 1 teaspoon diamond crystal kosher salt, plus more to taste reduce to ½ teaspoon if using anything else
- ½ teaspoon black pepper, plus more to taste
- 1 large head of cauliflower, cut into florets about 6 cups
- 3 medium Yukon gold potatoes, peeled and cut into 1-inch cubes about 3 cups
- 4 cups chicken or vegetable broth
- 1 tablespoon champagne vinegar could also use white wine vinegar or lemon juice
Additional topping ideas
- crispy prosciutto crumbles
- bacon crumbles
Instructions
- Add a drizzle of olive oil to a large pot over medium heat. Cook the sliced leeks (white and light green parts only) for 5-7 minutes, stirring occasionally until soft and starting to brown. If they're browning too quickly, turn the heat down to medium-low. When there's about a minute left, stir in the minced garlic, dried thyme, salt, and black pepper.
- Add the cauliflower florets, cubed potatoes, and broth. Gently simmer over medium to medium-low heat for 15-20 minutes until the cauliflower and potatoes are fork-tender.
- While the soup is simmering, thinly slice the leek greens and saute them in two tablespoons of olive oil in a large skillet over medium heat, stirring occasionally until soft with some brown bits. Season with salt, to taste.
- Puree the soup using an immersion blender right inside the pot or a regular stand blender until completely smooth. Stir in the vinegar or lemon juice and season with more salt to taste. Divide the soup into bowls and serve topped with the sauteed leek greens and any additional toppings if desired.
