LEEKS POTATO SOUP RECIPES

Steps:

• Preheat the oven to 400 degrees F.
• Combine the potatoes and leeks on a sheet pan in a single layer. Add the olive oil, 1 teaspoon salt, and 1/2 teaspoon pepper and toss to coat the vegetables evenly. Roast for 40 to 45 minutes, turning them with a spatula a few times during cooking, until very tender. Add the arugula and toss to combine. Roast for 4 to 5 more minutes, until the arugula is wilted. Remove the pan from the oven and place over 2 burners. Stir in the wine and 1 cup of the chicken stock and cook over low heat, scraping up any crispy roasted bits sticking to the pan.
• In batches, transfer the roasted vegetables to a food processor fitted with the steel blade, adding the pan liquid and about 5 cups of the chicken stock to make a puree. Pour the puree into a large pot or Dutch oven. Continue to puree the vegetables in batches until they're all done and combined in the large pot. Add enough of the remaining 1 to 2 cups of stock to make a thick soup. Add the cream, creme fraiche, 2 teaspoons salt, and 1 teaspoon pepper and check the seasonings.
• When ready to serve, reheat the soup gently and whisk in 2 tablespoons white wine and 1/4 cup of Parmesan. Serve hot with an extra grating of Parmesan and crispy shallots, if using.
• Heat the oil and butter in a saucepan over medium-low heat until it reaches 220 degrees F on a candy thermometer.
• Reduce the heat to low, add the shallots, and cook for 30 to 40 minutes, until they are a rich golden brown. The temperature should stay below 260 degrees F. Stir the shallots occasionally to make sure they brown evenly. Remove them from the oil with a slotted spoon, drain well, and spread out to cool on paper towels. Once they have dried and crisped, they can be stored at room temperature, covered, for several days.

Steps:

• Heat a large skillet over medium heat. Add the bacon strips and cook until golden brown, 6-8 minutes. Remove to a paper towel lined plate. Reserve 2 pieces for garnish.  Crumble the remaining 4 pieces. 
  Place the crumbled bacon, potatoes, celery, leek, garlic, stock, salt, thyme sprigs, and pepper in the base of a 6- to 8-quart slow cooker. Put the lid on the slow cooker, and cook on high for 4 hours (or low for 6 to 8 hours) until the potatoes are tender when pierced with a fork.  Remove the thyme sprigs and discard. Use an immersion blender to blend the soup to a semi-smooth consistency, leaving small chunks of potato and vegetables for texture. Stir in the sour cream. (Add 1/4 - 1/2 cup of water, to thin the soup out to your desired consistency). Serve in bowls, garnished with cheese, chives, additional sour cream, and the reserved bacon slices crumbled over top.
