• 4 cups cauliflower florets
• 1 medium leek, sliced into 1/4" rounds
• 3 large cloves garlic
• 1 tablespoon olive oil
• 1/4 teaspoon Kosher Salt
• 1 tablespoon butter
• 1 medium shallot, finely diced
• 1-1/2 cups vegetable broth
• 2 cups water
• 1 teaspoon Herbes de Provence 
• 1/4 cup cream
• salt & freshly ground pepper
• Finely chopped chives, for garnish

Preheat the oven to 425 degrees.

In a large bowl, combine the cauliflower, leeks, garlic, olive oil and salt. Toss to coat.

Transfer the vegetables to a rimmed sheet pan, then remove the garlic cloves and wrap them loosely in a small piece of foil. Place the foil packet back on the sheet pan and roast 20-25 minutes, until the cauliflower is nicely browned and can be easily pierced with a fork.

In a large Dutch oven, melt the butter over medium heat. Add the shallot and sauté until it is fragrant and translucent, about 5 minutes. Add the roasted vegetables, vegetable broth, water and 1/2 teaspoon Herbes de Provence. Increase the heat to high, bringing the soup to a boil, then lower the heat and simmer 5-10 minutes, allowing the flavors to combine.

Remove from heat and allow the soup to cool enough to safely handle.Transfer to a blender and puree on high.

Transfer the soup back to the Dutch oven over low heat. Stir in the cream and remaining 1/2 teaspoon Herbes de Provence. Heat to serving temperature.

Garnish with finely chopped chives.
