Making Potato and Leek Soup is straightforward if you follow these easy steps:

1. Prepare the Leeks: Clean the leeks thoroughly to remove any dirt. Slice them into rounds and set aside.
2. Cook the Onion and Leeks: In a large pot, melt the butter over medium heat. Add the chopped onion and sliced leeks. Cook for about 5-7 minutes, stirring occasionally until softened but not browned.
3. Add Potatoes: Add the diced potatoes to the pot, mixing well with the onion and leeks.
4. Add Broth: Pour in the vegetable or chicken broth. Bring the mixture to a boil.
5. Simmer: Reduce heat to a simmer and cover the pot. Let it cook for about 25-30 minutes, or until the potatoes are tender.
6. Blend the Soup: Once the potatoes are tender, use an immersion blender to blend the soup until smooth. Alternatively, transfer the soup to a blender in batches and blend until smooth. Be careful with the hot liquid.
7. Add Cream (Optional): Stir in the heavy cream for a richer flavor and adjust the seasoning with salt and pepper to taste.
8. Heat Through: Allow the soup to heat through for a few minutes on medium heat, stirring occasionally.

By the end of these steps, you’ll have a beautifully smooth and creamy Potato and Leek Soup ready to be served.
