Classic Leek and Potato Soup Recipe
Ingredients:
- Butter (or olive oils): 2 tablespoons
- Two large leeks, only the white and light-green parts, washed and sliced
- 1 medium onion, diced
- 2 minced garlic cloves (optional)
- Peel and dice 3 medium potatoes (about 550g)
- Vegetable or chicken stock, 4 cups
- Add 1 cup of milk or cream to the recipe for a creamy texture
- To taste: salt and pepper
- Fresh thyme and parsley for garnish
- Croutons or crusty bread for serving
Step-by-Step Instructions
Step 1: Prepare Leeks
Cleaning leeks properly is important because they can accumulate a lot dirt between the layers. Remove the roots and tops of the leeks, then slice them lengthwise. Rinse under running water to separate the layers and remove any grit. Slice thinly.
Step 2 – Saute the Aromatics
Melt the butter in a large saucepan over medium heat. Add the leeks and onions. Stirring often, cook gently for approximately 10 minute until the vegetables become soft and fragrant, but not brown.
Add the garlic (if you are using it) and continue to cook for 1-2 more minutes.
Step 3: Add the potatoes and stock
Pour in the stock and stir in the potatoes. Stir in the diced potatoes and pour the stock. Bring to a gentle simmer, then turn the heat down to low.
Step 4: Blending the Soup
Remove the soup from the heat once the vegetables have softened. To get a smoother soup, you can use a stick blender to puree the mix directly in the pot. Transfer the mixture to a blender, blend it until smooth and then return it to the pot.
To achieve a rustic texture, blend only half of the soup, then mix it into the pot. Or, mash some potatoes with a fork.
Step 5: Add Cream or Milk (Optional)
Pour enrichir the soup, add the cream or milk and warm gently without boiling. Add salt and pepper according to your taste.
Step 6: Garnish and Serve
Pour the soup in bowls, and sprinkle with fresh thyme or parsley. Add some cream, croutons or black pepper. Serve with crusty or toasted sourdough bread to dip.
