This roasted potato leek soup is creamy and comforting, perfect for chilly days. The potatoes get nice and soft, while the leeks add a lovely oniony flavor.
Honestly, this soup is like a warm hug in a bowl! I like to enjoy it with a slice of crusty bread. It’s so simple to make, and you’ll love how cozy it feels!
Key Ingredients & Substitutions
Leeks: Leeks add a mild onion flavor to the soup. Make sure to clean them well, as dirt can hide between the layers. If leeks are hard to find, you can use green onions or sweet onions instead for a different but tasty profile.
Potatoes: Yukon Golds bring a creamy texture and buttery flavor. If you’re in a pinch, Russet potatoes can work too, but they’ll be a little starchier. You can also try sweet potatoes for a unique twist on flavor!
Butter & Olive Oil: A combination of both helps enhance the richness of the soup. If you’re dairy-free, use vegan butter or just olive oil. The flavor will still be great!
Broth: Chicken broth gives a depth of flavor, but for a vegetarian option, vegetable broth works perfectly. You can also make your own broth at home if you have time—it’s super easy!
Heavy Cream: This adds creaminess to the soup. If you prefer a lighter version, use half-and-half or coconut cream for a dairy-free option. It will change the flavor slightly but keeps the texture smooth.
How Can I Get My Onions Perfectly Caramelized for Garnish?
Caramelizing onions might seem tricky, but with patience, you can achieve that delicious sweetness. The key is cooking them slowly. Follow these steps and tips for success:
- Heat 1 tablespoon of olive oil or butter in a skillet over medium heat.
- Add thinly sliced onions and stir to coat them evenly in fat.
- Cook undisturbed for the first 5-7 minutes, then stir occasionally for about 20 minutes until they turn golden brown.
- If they start to stick, lower the heat and add a splash of water or broth to deglaze the pan.
Remember, the low and slow approach is what brings out their natural sugars!
How to Make Ina Garten’s Roasted Potato Leek Soup
Ingredients You’ll Need:
For the Soup:
- 3 large leeks (white and light green parts only), cleaned and sliced
- 4 large Yukon Gold potatoes, peeled and cut into 1-inch cubes
- 3 tablespoons unsalted butter
- 3 tablespoons olive oil
- 4 cups chicken broth (or vegetable broth for vegetarian)
- 2 cups water
- 1 cup heavy cream
- Salt and freshly ground black pepper, to taste
- Fresh thyme leaves (optional)
For Serving:
- 1 cup sour cream or crème fraîche
- Fresh dill or chives, chopped for garnish
- 1 large onion, thinly sliced (for caramelizing)
- Additional olive oil or butter (for frying onions)
How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and around 1 hour for cooking. You’ll spend some time chopping and prepping the ingredients, roasting the potatoes, and blending the soup to creamy perfection. Overall, it takes about 1 hour and 15 minutes from start to finish.
Step-by-Step Instructions:
1. Prepare the Leeks:
Start by cleaning your leeks thoroughly. Remove any dirt by rinsing them under water, ensuring you clean between the layers. Slice the white and light green parts thinly so they can cook evenly.
2. Caramelize the Onions for Garnish:
In a skillet, heat a tablespoon of olive oil or butter over medium heat. Add your thinly sliced onions. Cook them slowly, stirring occasionally, until they’re beautifully golden brown and caramelized—this should take about 15-20 minutes. Once done, set them aside.
3. Roast the Potatoes:
Preheat your oven to 400°F (200°C). In a large bowl, toss your cubed potatoes with a tablespoon of olive oil, and season with salt and pepper. Spread them onto a baking sheet in a single layer and roast for 25-30 minutes, or until they’re golden and tender.
4. Cook the Leeks:
In a large pot, combine the butter and the remaining olive oil over medium heat. Once melted, add the prepared leeks (and fresh thyme if you’re using it). Cook gently, stirring occasionally, until the leeks have softened but haven’t browned—this should take about 10 minutes.
5. Add Potatoes and Broth:
Once the leeks are soft, add your roasted potatoes to the pot. Then pour in the chicken broth and water. Turn up the heat to bring everything to a boil, then reduce it to a simmer. Let this cook together for 15-20 minutes for all the flavors to meld beautifully.
6. Blend the Soup:
Using an immersion blender, puree the soup until it’s smooth and creamy. If you don’t have one, carefully transfer the soup in batches to a blender, then blend until smooth. Return the pureed soup back to the pot.
7. Finish with Cream:
Stir in the heavy cream. Warm the soup gently over low heat without bringing it to a boil. Taste and then season with salt and freshly ground black pepper as needed.
8. Serve:
Ladle the hot soup into bowls. Top with a dollop of sour cream or crème fraîche. Don’t forget to sprinkle your caramelized onions and fresh dill or chives on top for that added flavor!
9. Optional Accompaniment:
This soup pairs wonderfully with crusty bread or rolls. Enjoy every cozy spoonful!
Can I Use Different Types of Potatoes?
Yes! While Yukon Gold potatoes are ideal for their creamy texture, you can substitute with Russet potatoes for a slightly different flavor or sweet potatoes for a healthier twist!
Can I Make This Soup in Advance?
Absolutely! You can prepare the soup a day ahead of time. Just refrigerate it after cooking. Reheat gently on the stove, adding a splash of cream if it thickens too much.
Is There a Non-Dairy Option for This Soup?
Yes! You can use a combination of coconut milk and vegetable broth instead of heavy cream and chicken broth. It will give the soup a different but delicious flavor!
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, gently warm on the stove or in the microwave while stirring occasionally for even heating.
