Leek And Potato Soup Base Recipes

Steps:

• Chop the leeks into small pieces.
• In a 6-quart saucepan over medium heat, melt the butter. Add the leeks and a heavy pinch of salt and sweat for 5 minutes. Decrease the heat to medium-low and cook until the leeks are tender, approximately 25 minutes, stirring occasionally.
• Add the potatoes and the vegetable broth, increase the heat to medium-high, and bring to a boil. Reduce the heat to low, cover, and gently simmer until the potatoes are soft, approximately 45 minutes.
• Turn off the heat and puree the mixture with an immersion blender until smooth. Stir in the heavy cream, buttermilk, and white pepper. Taste and adjust seasoning if desired. Sprinkle with chives and serve immediately, or chill and serve cold.

Steps:

• Heat the butter in a large wide pot over medium heat. Add the garlic, leeks and onion and cook, covered, stirring occasionally, until soft and not browned, about 12 minutes. Raise the heat to medium-high, pour in the wine and continue to cook, uncovered, until almost dry, about 4 minutes.
• Add the potatoes, bay leaf, thyme, 7 cups water, 1 teaspoon salt and a few grinds of pepper. Bring to a boil, reduce the heat to maintain a simmer and cook, covered, until the potatoes are very tender, about 20 minutes. Remove from the heat and cool slightly.
• Remove and discard the thyme and bay leaf. Working in batches, transfer the mixture to a blender and carefully puree until smooth, taking care not to fill the carafe more than half full per batch, or puree with an immersion blender in the pot. Reheat the soup over medium heat until steaming.
• Whisk in the cream and lemon juice. Adjust the seasoning with additional salt and pepper. Ladle the soup into bowls. Garnish with fresh thyme leaves, a drizzle of oil and a frizzled leeks or shallot if using.

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:

• Halve the leeks lengthwise and rinse away any grit. Thinly slice the leeks crosswise. In a small square of cheesecloth, tie together bay leaves, thyme, sage, parsley and celery leaves if using.
• Melt the butter or heat the oil in the bottom of a large pot over medium-high heat. Stir in the leeks and cook, stirring frequently, until leeks are soft and dark golden brown, 10 to 15 minutes. Stir in the garlic for the last 3 minutes of cooking.
• Stir in stock or water, the sachet of herbs, the salt and pepper. Bring to a boil over high heat, then reduce immediately to medium-low; simmer for 5 minutes.
• Add the potatoes and simmer soup until potatoes are very tender and falling apart, about 45 minutes. Taste and adjust seasoning. If desired, drizzle a small amount of cream into each bowl when serving, and top with parsley for garnish.

Steps:

• Melt 50g butter in a heavy saucepan. When it foams, add 450g potatoes, cut into 1cm cubes, 1 small onion, cut the same as the potatoes, and 450g white parts of leeks, sliced and toss them in the butter until they are well coated.
• Season well with salt and freshly ground pepper and toss again. Put a disc of greaseproof paper (called a cartouche by chefs) on top of the vegetables to keep in the steam), then cover the pan with its lid.
• Cook over a gentle heat for 10 mins, or until the vegetables are soft but not coloured.
• Uncover the pan and discard the paper. Pour in 850ml of the light chicken or vegetable stock, bring to the boil and simmer until the vegetables are just cooked - about 5 minutes. Do not overcook or the soup will lose its fresh flavour.
• Purée in a blender until silky smooth, in batches if necessary, then taste and adjust the seasoning. Return the soup to a clean pan and stir in three quarters of a 142ml carton of whipping cream and 125ml full-fat milk.
• To finish the soup, finely shred the white part of 1 leek and gently cook it in a small knob of hot butter for a few mins until it is softened but not coloured.
• Reheat the soup to a gentle simmer (add some extra stock at this point if the soup is too thick for your liking), then pour into warmed bowls.
• Drizzle the remaining cream over each serving, top with a little pile of buttered leeks and a scattering of chives and black pepper and serve at once.
