Kohlrabi Leek Soup Recipes

Steps:

• Melt butter in a large stockpot over medium-low heat. Cook and stir onion in melted butter until soft, about 10 minutes. Add kohlrabi; cook and stir another 2 minutes. Pour vegetable broth and milk over the onion mixture. Add bay leaf. Bring the mixture to a boil, place a cover on the pot, and reduce heat to low; cook at a simmer until kohlrabi is tender, about 25 minutes.
• Remove and discard bay leaf; allow the soup to cool slightly. Pour the soup into a blender, filling the pitcher no more than halfway. Pulse the blender a few times before leaving on to puree. Work in batches until all soup is blended. Return pureed soup to stockpot; season with salt and pepper. Sprinkle orzo pasta into the soup; cover the stockpot and simmer until the orzo is tender, about 10 minutes.

Steps:

• Melt the butter in a large pot over medium-high heat, add the leeks and cook until soft and golden around the edges, 5 to 7 minutes. Add the cabbage and garlic and cook, stirring occasionally, until cabbage begins to caramelize, about 10 minutes.
• Stir in potatoes, stock, 4 cups water, salt and thyme. Bring soup to a simmer and cook, partly covered, until potatoes begin to fall apart, 45 to 50 minutes. Add more water, as needed, to reach the desired consistency. Season with black pepper and serve, topped with cheese.

Steps:

• Wash sliced leeks in a large bowl of cold water, agitating them, then lift out and drain well in a colander.
• Cook leeks, onion, carrot, celery, salt, and pepper in 4 tablespoons butter in a 5- to 6-quart heavy pot over moderate heat, stirring occasionally, until softened, about 8 minutes. Peel potato and cut into 1/2-inch cubes, then add to onion mixture along with wine, stock, water, and bay leaf. Bring to a boil, then reduce heat and simmer, partially covered, until vegetables are tender, about 15 minutes.
• Stir in parsley and simmer soup, uncovered, 5 minutes. Discard bay leaf and keep soup at a bare simmer.
• Melt remaining 4 tablespoons butter in a 1-quart heavy saucepan over moderate heat, then add flour and cook roux, whisking, until golden, about 3 minutes. Remove from heat and add 2 cups simmering stock (from soup), whisking vigorously (mixture will be thick), then whisk mixture into remaining soup and return to a simmer, whisking.
• Blend soup in 4 batches in a blender until smooth (use caution when blending hot liquids), about 1 minute per batch, transferring to a 3- to 4-quart saucepan. Reheat if necessary, then season with salt and pepper.
• Beat cream in a bowl with an electric mixer at medium speed until it almost forms soft peaks. Serve soup topped with cream.
