Detailed Recipe for Leek Potato Soup
Ingredients
- 4 large leeks (white and light green parts only, cleaned and chopped)
- 4 medium-sized potatoes (peeled and diced)
- 1 medium onion (chopped)
- 4 cups vegetable or chicken broth
- 1 cup heavy cream or cashew cream (for vegan option)
- 2 tablespoons olive oil or butter
- Fresh herbs for garnish (e.g., chives, parsley)
- Salt and pepper to taste
Directions
1. Preparing the Leeks: Begin by cleaning the leeks thoroughly. Cut off the dark green tops and root ends; slice them lengthwise and rinse under cold water to remove any grit. Chop the cleaned leeks into small pieces, focusing on the white and light green parts for the best flavor.
2. Sautéing Vegetables: In a large pot, heat the olive oil or butter over medium heat. Add the chopped leeks and onions, sautéing for about 5-7 minutes until they become tender and fragrant. Follow with the diced potatoes and stir, ensuring they are coated in the oil and mixed with the sautéed leeks.
3. Cooking the Soup Base: Pour in the vegetable or chicken broth, bringing the mixture to a boil. Once boiling, reduce the heat to a simmer, and allow the soup to cook for about 20-25 minutes, or until the potatoes are fork-tender. Keep covered to maintain moisture and flavor.
4. Blending the Soup: Once cooked, remove the pot from heat. Use an immersion blender to blend the soup to your desired consistency—smooth for a silky finish or leave a few chunks for a more rustic texture. If using a regular blender, allow the soup to cool slightly before carefully blending in batches and returning it to the pot.
5. Finishing Touches: Stir in the cream or cashew cream, adjusting the richness to your preference. Season with salt and pepper to taste, allowing the flavors to meld for a few more minutes over low heat.
6. Garnishing and Serving Suggestions: Serve hot, garnished with freshly chopped herbs such as chives or parsley. Pair with crusty bread or crackers for a lovely meal that comforts and satisfies.
