Key Ingredients & Substitutions
Garlic: One whole head of garlic gives this soup its delicious roasted flavor. If you’re not a fan, you can reduce the amount or use garlic powder instead, though fresh garlic is best for taste.
Leeks: These bring a mild onion flavor. If you can’t find leeks, green onions or yellow onions work as alternatives, keeping in mind they have a stronger flavor. Just use less than you would of leeks.
Potatoes: I recommend using starchy potatoes like russets for a creamy texture. If you want to make it lighter, try cauliflower instead of some or all of the potatoes.
Broth: Vegetable or chicken broth will work well. If you’re vegetarian or vegan, stick with vegetable broth. I often use homemade broth for a richer flavor, but store-bought is fine too!
Heavy Cream or Milk: For creaminess, I use heavy cream, but whole milk will work if you’re looking for a lighter option. You can also use coconut milk for a dairy-free version, which adds a unique taste.
How Do You Get the Best Flavor from Roasted Garlic?
Roasting garlic transforms its flavor, making it sweet and mellow. Start by slicing the top off the head of garlic to expose the cloves. Drizzle olive oil, then wrap it in foil. Bake at 400°F for 30 to 40 minutes until soft.
- This method draws out the sweetness – perfect for the soup!
- Let it cool a bit before handling; the cloves will be hot.
- The roasted garlic can be squeezed directly from the skins into your pot for easy mixing.
How to Make Roasted Garlic Potato Leek Soup
Ingredients You’ll Need:
For the Soup:
- 1 whole head garlic
- 2 tablespoons olive oil, divided
- Salt and pepper to taste
- 4 large leeks (white and light green parts only), cleaned and sliced
- 4 large potatoes, peeled and diced

How Much Time Will You Need?
This delicious soup takes about 15 minutes to prep and around 30 to 40 minutes to cook. You’ll also need some time to blend it. Altogether, expect about 1 hour from start to finish. Perfect for a cozy dinner!
Step-by-Step Instructions:
1. Roast the Garlic:
First, preheat your oven to 400°F (200°C). Slice the top off the whole head of garlic, drizzle it with 1 tablespoon of olive oil, and wrap it in foil. Place it in the oven and roast for about 30 to 40 minutes, until it’s soft and caramelized. Once done, let it cool a bit.
2. Prepare the Vegetables:
While the garlic is roasting, take the time to slice your leeks and dice the potatoes. Remember to just use the white and light green parts of the leeks!
3. Sauté the Leeks:
In a large pot, heat the remaining 1 tablespoon of olive oil over medium heat. Add the sliced leeks and a pinch of salt. Sauté them gently for about 8 to 10 minutes until they are softened but not browned. This step gives the soup a lovely flavor!
4. Add Garlic, Potatoes, and Broth:
Once the leeks are tender, squeeze the roasted garlic cloves out of their skins directly into the pot. Add the diced potatoes and pour in the broth. Bring it all to a boil, then reduce the heat and let it simmer for about 20 minutes, or until the potatoes are very tender.
5. Blend the Soup:
Using an immersion blender, carefully puree the soup right in the pot until it’s smooth. If you don’t have an immersion blender, you can carefully transfer the soup in batches to a blender to puree it. Just be cautious as the soup will be hot!
6. Add Cream and Seasoning:
If you want an extra creamy soup, stir in the heavy cream or whole milk. Heat it gently without boiling. Finally, season to taste with salt and pepper.
7. Serve and Enjoy:
Serve the soup hot, garnished with fresh thyme or chives, and drizzle a little olive oil on top. Don’t forget the croutons on the side or on top for a nice crunch!
Enjoy your creamy, comforting roasted garlic potato leek soup!
Can I Use Other Types of Potatoes?
Absolutely! While starchy potatoes like russets give a creamy texture, you can also use Yukon Golds or even a mix. If you’re looking for a lighter option, cauliflower can substitute for some or all of the potatoes, giving it a different flavor yet still keeping it creamy.
How Long Can I Store Leftover Soup?
Leftover roasted garlic potato leek soup can be stored in an airtight container in the refrigerator for up to 3 days. If you want to keep it longer, consider freezing it for up to 3 months. Just remember to leave some space in the container as the soup will expand when frozen!
Can I Make This Soup Vegan?
Yes! To make it vegan, simply substitute the heavy cream or milk with a plant-based alternative like coconut milk or almond milk. Also, use vegetable broth instead of chicken broth. The flavor will still be delicious!
How Do I Reheat the Soup?
To reheat, gently warm the soup on the stove over low heat, stirring occasionally. You can also microwave individual servings, simply heat in short intervals, stirring in between to ensure even warmth. Be careful not to boil it again if you’ve added cream!
