Potato leek soup with onion and milk

Potato leek soup with onion and milk is a comforting and creamy dish that's perfect for chilly days. This classic soup combines the delicate flavors of leeks and onions with the heartiness of potatoes, all brought together with a touch of milk for creamy goodness. It's simple to make and requires just a few ingredients, making it a great option for a weeknight meal.

Instructions:

1. Prepare Ingredients:
- Wash the leeks thoroughly to remove any dirt or sand. Chop the white and light green parts into thin slices.
- Peel and cube the potatoes.
- Finely chop the half onion.
2. SautΓ© Vegetables:
- In a large pot, melt the 1 tablespoon of butter over medium heat.
- Add the chopped leeks and onion to the pot. SautΓ© for about 5-7 minutes, or until they become soft and translucent, stirring occasionally.
3. Thicken the Base:
- Sprinkle the 1 tablespoon of flour over the softened vegetables in the pot.
- Stir constantly for about 1-2 minutes to incorporate the flour and eliminate the raw taste.
4. Add Broth and Potatoes:
- Slowly pour in the 4 cups of chicken broth, stirring continuously to combine.
- Add the cubed potatoes to the pot.
5. Simmer:
- Bring the mixture to a boil over high heat.
- Once boiling, reduce the heat to medium-low. Allow the soup to simmer for approximately 20-25 minutes, or until the potatoes are tender when pierced with a fork.
6. Blend the Soup:
- Using an immersion blender, blend the soup until smooth and creamy. (Alternatively, carefully transfer the soup in batches to a regular blender and blend until smooth, then return to the pot.)
7. Add Milk and Season:
- Stir in the 1/2 cup of milk.
- Season the soup with a dash of salt and black pepper to taste.
8. Heat Through:
- Continue to cook over low heat for an additional 5 minutes, stirring occasionally to let the flavors meld and ensure the soup is heated through.
9. Serve:
- Ladle the hot soup into bowls and serve immediately. Optional: Garnish with a few extra slices of sautΓ©ed leeks or a sprinkle of chopped fresh herbs, like parsley or chives, for added freshness and color.

Potato leek soup with onion and milk FAQ:

How long should I simmer the soup?

You should simmer the soup for approximately 20-25 minutes, or until the potatoes are tender when pierced with a fork.

Can I use a different type of milk in this recipe?

Yes, you can substitute 2% milk with whole milk for a creamier texture or non-dairy alternatives like almond or oat milk, though the flavor and consistency may vary slightly.

What is the best way to store leftover potato leek soup?

Store any leftover soup in an airtight container in the refrigerator for up to 3-4 days. For longer storage, consider freezing it in portions for up to 3 months.

How can I tell when the potatoes are done?

The potatoes are done when they are tender and easily pierced with a fork. This usually takes about 20-25 minutes of simmering.

What can I use as a substitute for chicken broth?

You can use vegetable broth for a meat-free option, or water with added seasonings for a milder flavor. Just note that it may alter the overall taste of the soup.

Cooking Tips:

- Make sure to clean the leeks thoroughly, as they can contain dirt between the layers. A good method is to slice them and rinse them in a bowl of water.

- To make the soup more velvety, you can blend it using an immersion blender after cooking. For a chunkier texture, blend only half of the soup and leave the rest as is.

- You can substitute chicken soup with vegetable broth if you prefer a vegetarian version.

- Season gradually and adjust according to taste. Start with a dash of salt and pepper and add more if needed.

- A dollop of sour cream or a sprinkle of fresh herbs can be added as a garnish to enhance the flavor and presentation of the soup.
