Instructions to Make James Martin Leek and Potato Soup

Here are the steps to make James Martin’s leek and potato soup:

Step 1: Prepare the leeks and potatoes

  • The first step is to prepare the leeks and potatoes. Wash the leeks well under running water and slice them thinly. Discard the tough green parts and use only the white and light green parts. Peel and slice the potatoes into even pieces. You can use any type of potato, but waxy potatoes are better for this soup as they hold their shape better and don’t turn mushy.

Step 2: Cook the leeks and potatoes

  • The next step is to cook the leeks and potatoes in a large saucepan. Add the milk, cream, salt, and pepper to the saucepan and bring to a boil over medium-high heat. Then, reduce the heat and simmer for 6 to 8 minutes, or until the potatoes are tender. Stir occasionally to prevent the milk from scorching.

Step 3: Blend the soup

  • Once the leeks and potatoes are cooked, you can blend the soup to make it smooth and creamy. You can use a hand blender, a food processor, or a blender to do this. Be careful when blending hot liquids, as they can splatter and burn you. Blend the soup in batches if necessary, and transfer to a clean saucepan. Keep the soup warm over low heat while you prepare the toppings.

Step 4: Make the cheese toast

  • To make the cheese toast, you will need some toasted sourdough bread, crumbled stilton cheese, and double cream. Mix the cheese and cream together in a small bowl and spread it over the toast. Then, grill the toast until the cheese is melted and bubbly. Cut the toast into bite-sized pieces and set aside.

Step 5: Make the crispy leeks

  • To make the crispy leeks, you will need some julienne leeks, double cream, olive oil, and salt. Julienne leeks are leeks that are cut into thin strips. You can use a mandoline, a knife, or a food processor to do this. Rinse the leeks well and pat them dry with paper towels. Then, toss them with some cream and salt in a bowl. Heat some oil in a frying pan over high heat and fry the leeks in batches until golden and crisp. Drain them on paper towels and keep them warm.

Step 6: Serve the soup

  • To serve the soup, ladle it into warm bowls and top with some crumbled stilton cheese, a drizzle of cream and oil, and some crispy leeks. Serve with the cheese toast on the side and enjoy!

Expert Tips to Make Perfect James Martin Leek and Potato Soup

Here are some pro tips to make this soup even better:

  • Select High-Quality Ingredients: The essence of a great soup lies in its ingredients. Opt for organic leeks, potatoes, and herbs to elevate the taste. Using homemade or low-sodium chicken stock can also make a significant difference. For a homemade stock, simmer chicken bones with vegetables and herbs for about two hours, then strain.
  • Thoroughly Clean and Prepare Leeks: Leeks, known for harboring dirt, require careful cleaning. Trim off the roots and the dark green parts, then slice them lengthwise. Rinse under running water, ensuring to separate the layers to remove any hidden grit. For extra cleanliness, soak them in water for 10 minutes before a final rinse.
  • Achieve a Smooth Texture with Blending: For a velvety consistency, blend the cooked soup. Whether using a stand blender, an immersion blender, or a food processor, ensure the soup is smoothly pureed. For a rustic feel, you can leave it chunky or lightly mash it.
  • Customize Soup Consistency and Flavor: Personalize your soup by adjusting its thickness and seasoning. Add more liquid (stock, water, broth, or milk) to alter its consistency. Experiment with seasonings like salt, pepper, thyme, and even additional spices like nutmeg or bay leaf to find your perfect flavor profile.

Variations of James Martin Leek and Potato Soup

Here are some variations of this soup that you can try, to make it different and interesting:

  • With Bacon: Enhance the soup with a smoky crunch by adding crispy bacon bits. Fry bacon until crisp, chop finely, and either mix into the soup or use as a topping.
  • With Corn: Introduce sweetness and color by incorporating corn kernels – fresh, frozen, or canned. Add them to the pot with potatoes or after blending for a touch of sweetness. Creamed corn is also a great option for added creaminess.
  • With Cheese and Onion Scones: Complement the soup with homemade cheese and onion scones. Mix flour, baking powder, butter, cheese, and onion, then add milk to form a dough. Roll, cut into circles, and bake until golden. Serve warm with the soup for added indulgence.

How do I store James Martin Leek and Potato Soup Leftovers?

  • Cooling the Soup: Prioritize safety by cooling the soup thoroughly before storage. This can be done by placing the soup in a large bowl within an ice bath or distributing it in a shallow dish in the refrigerator. Once the soup reaches room temperature, it’s ready for storage.
  • Labeling for Freshness: Ensure you can easily track the freshness of your soup by labeling the storage container. Use a marker or a label to note the date of preparation. Including reheating instructions on the label can also be helpful for future reference.
  • Preventing Container Damage: To accommodate the natural expansion of the soup, leave about one inch of space at the top of the storage container. This precaution prevents the container from bursting or leaking, ensuring your soup remains intact.

How do I reheat James Martin Leek and Potato Soup Leftovers?

  • Thawing Frozen Soup: If your soup is frozen, allow sufficient time for thawing to simplify reheating. Place it in the refrigerator overnight or use the microwave’s defrost setting to gently thaw the soup without cooking it.
  • Gentle Reheating: To maintain the soup’s quality, reheat it over low to medium heat. Whether using a stovetop or a microwave, stir the soup occasionally. This ensures even heating and prevents the soup from sticking to the pot or overheating in the microwave. Keep monitoring the temperature until the soup is thoroughly warmed.
