Ingredients for alison roman potato leek soup
Six ingredients make this velvety soup a game-changer—crispy crowns and all.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 2 whole | Medium, sliced into half-moons |
| Leeks 🧅 | 3 whole | White and light green parts only |
| Celery Stalks 🥬 | 4 whole | Thick, for crispy crowns |
| Russet Potatoes 🥔 | 2 lb | Yukon Gold or red preferred |
| Fresh Dill 🌿 | ½ cup | Chopped, stems removed |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Chicken Stock 💧 | 4 cups | Homemade or high-quality |
| Butter 🧈 | 4 tbsp | Unsalted, for sautéing |
| Garlic Cloves 🧄 | 4 cloves | Minced, for depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Olive Oil 🫒 | 2 tbsp | For crispy celery crowns |
| Crème Fraîche 🥛 | ¼ cup | Optional, for finishing |
The leeks are the star here. Look for fresh, crisp ones—avoid any with wilted greens or brown spots. I always grab mine from the produce section at Whole Foods or my local farmers market, where they're the freshest. The potatoes should be firm and free of sprouts—Yukon Golds give the best creamy texture, but Russets work too. For the celery, thick stalks are key—they crisp up perfectly when fried. Fresh dill is a must; dried just won't give that bright, aromatic punch. If you can't find fresh, dried dill at half the amount works in a pinch, but trust me, it's worth hunting down the fresh stuff.
No heavy cream? Coconut milk or cashew cream keeps it vegan without sacrificing richness. Chicken stock can be swapped for vegetable stock if you're vegetarian, just add a splash of soy sauce for umami depth. The butter is non-negotiable for sautéing—don't use margarine. For the celery crowns, olive oil is your friend—it crisps them up beautifully. If you're short on time, pre-cut celery crowns from the grocery store work in a bind. And that crème fraîche? Skip it if you're watching calories—the soup is still delicious without it.
This soup tastes even better the next day—make a double batch and freeze half. Store leftovers in the fridge for up to 5 days, or freeze for 3 months. The crispy celery crowns stay crunchy for about 2 hours after frying, so make them fresh when serving. I like to reheat the soup gently on the stove, then top with fresh celery crowns right before serving. Portion into jars for easy lunches—just add a dollop of crème fraîche when you're ready to eat.

Step-by-step instructions for Alison Roman's potato leek soup
Here's how to create Alison Roman's signature velvety soup with perfect crispy celery crowns.
Sauté the Aromatics Until Fragrant
Melt 4 tablespoons butter in a large Dutch oven over medium heat. Add the 2 whole yellow onions and 3 whole leeks (white and light green parts only, sliced into half-moons). Cook for 8-10 minutes until softened and translucent, stirring occasionally to prevent browning.
Add the 4 whole celery stalks (cut into thick slices for crispy crowns) and cook for another 5 minutes until they begin to soften but still maintain their shape. Here's the thing—don't rush this step. You want those vegetables to release their natural sweetness and form the flavor base for your soup.
Add Potatoes and Garlic for Depth
Peel and dice the 2 lb russet potatoes into 1-inch cubes and add them to the pot. Stir to coat in the butter and vegetable mixture. Add the 4 cloves minced garlic and cook for 1 minute until fragrant—this prevents the garlic from burning while still infusing its flavor.
Pour in the 4 cups chicken stock and bring to a gentle boil. Reduce heat to low and let it simmer for 20-25 minutes until the potatoes are fork-tender. You'll know they're ready when a knife slides in easily, but there's still a slight resistance in the center. This ensures your soup has a perfect texture without being mushy.
Blend Until Silky Smooth
Remove the soup from heat and let it cool slightly for 5 minutes. Use an immersion blender to blend until completely smooth—this is where the magic happens. The soup should be velvety with no lumps. If you don't have an immersion blender, carefully transfer the soup to a countertop blender in batches and blend until smooth.
Return the blended soup to the pot and stir in the 1 cup heavy cream. Season with 1.5 teaspoons salt and 0.5 teaspoon black pepper. Taste and adjust seasoning if needed—this is your chance to perfect the flavor balance. The soup should be rich but not overly salty, with a hint of creaminess that makes it irresistible.
Finish with Fresh Dill and Crispy Celery Crowns
Gently heat the soup back up over low heat until warmed through. Stir in the 0.5 cup chopped fresh dill just before serving—this adds a bright, herby note that cuts through the richness of the cream. The dill should be evenly distributed throughout the soup for that signature fresh finish.
For the crispy celery crowns, heat 2 tablespoons olive oil in a separate skillet over medium-high heat. Add the celery slices (from the original 4 whole celery stalks) and fry for 3-4 minutes on each side until golden brown and crispy. You'll know they're ready when they release easily from the pan and have a satisfying crunch.
Serve with Crème Fraîche and Celery Crowns
Ladle the warm soup into bowls and top each serving with a generous spoonful of 0.25 cup crème fraîche and a few crispy celery crowns. The contrast of the creamy, velvety soup with the crispy celery crowns is what makes this dish truly special. Serve immediately while the celery crowns are still crisp and the soup is piping hot.
This is the moment that matters: each bite should deliver that perfect balance of creamy, savory, and fresh flavors. The crispy celery crowns add a delightful textural contrast that elevates the entire dish. Enjoy your soup with a slice of crusty bread to soak up every last drop of that delicious velouté!
Pro Tips For Making Alison Roman Potato Leek Soup
- SWIM THE LEEKS: Alison Roman’s recipe calls for rinsing leeks thoroughly, but I learned the hard way—those gritty layers hide in the crevices. Cut them lengthwise, fan open, and give each quarter a quick dunk in cold water. No need to scrub; just let the water do the work while you prep the rest.
- SWEAT THE ONIONS LOW: This isn’t a sear—it’s a slow, steady sweat. Keep the heat at a gentle simmer (medium-low) and resist the urge to rush. If the onions start to brown, you’ve gone too far. The goal is translucent, not caramelized. (Yes, even if you’re impatient like me.)
- POTATO SIZE MATTERS: Russets break down differently than Yukon Golds. Cut them into even 1-inch chunks—no small dice, no large wedges. Smaller pieces turn to mush; larger ones stay stubborn. Aim for consistency so every bite has that perfect creamy texture.
- STRAIN SMART: After blending, don’t pour the soup through a fine-mesh strainer—it’ll clog like crazy. Line a colander with cheesecloth or a clean kitchen towel, then strain. It takes 10 seconds longer but saves you from wrestling with a soggy mess. (Your future self will thank you.)
Health benefits of this recipe
Creamy Comfort Benefits
This velvety soup delivers healthy fats from the heavy cream and butter, which support brain function and satiety. The 1 cup of heavy cream provides about 15 grams of fat per serving, helping you feel full while providing energy.
The potatoes offer complex carbohydrates for steady blood sugar levels, making this a balanced meal. 💪
Herb-Packed Nutrition
The ½ cup fresh dill adds more than just flavor—it’s packed with vitamin K and antioxidants that support bone health and fight inflammation. Fresh dill also contains calcium and iron, which many people don’t get enough of in their diets.
I always use fresh dill because dried just doesn’t compare in nutritional benefits.
Protein Boost
While not a protein powerhouse, this soup pairs beautifully with lean proteins like grilled chicken or smoked salmon to create a complete meal. The chicken stock adds collagen and gelatin, which support gut health and joint function.
For a vegetarian version, swap the stock for vegetable broth and add white beans for extra protein and fiber.
Low-Calorie Adaptations
Want to lighten this up? Swap the heavy cream for Greek yogurt or coconut milk to cut calories while keeping creaminess. The crispy celery crowns add crunch without calories, making this a satisfying yet lighter option.
I’ve made this with ½ the cream and still loved the result—just as velvety, just lighter. ✨
Digestive-Friendly Ingredients
The leeks and celery are both prebiotic-rich, feeding the good bacteria in your gut. The potatoes provide potassium, which helps regulate blood pressure. For an extra digestive boost, add a pinch of ginger or turmeric while simmering—they aid digestion and reduce inflammation.
This soup is gentle on the stomach while still being deeply nourishing.
Meal Prep Advantage
This soup reheats beautifully, making it perfect for batch cooking. The potatoes and leeks hold their texture well when reheated gently, and the fresh dill can be added back in right before serving.
Freezing the base (without the celery crowns) lets you enjoy this comforting meal all week without sacrificing flavor. I always double the batch—leftovers taste even better the next day! 💡

Frequently asked questions
Can I make this soup without an immersion blender?
Transfer the hot soup to a countertop blender in batches, blending until completely smooth. Just be careful—hot liquid can cause splattering. For extra safety, place a kitchen towel over the blender lid before blending. The texture will be just as velvety as with an immersion blender.
How do I store leftovers?
Store the soup (without celery crowns) in an airtight container in the fridge for up to 5 days. For freezing, cool the soup completely, then transfer to a freezer-safe bag for up to 3 months. Reheat gently on the stove, then add fresh celery crowns and dill right before serving. The crispy crowns should always be made fresh when reheating.
What if I don't have fresh dill?
Use ½ teaspoon dried dill instead, but it won't have the same bright flavor. For a better alternative, try ½ teaspoon dried tarragon or a pinch of fennel seeds, both of which complement the soup's creamy base. Fresh herbs make all the difference in this recipe, so if possible, track down some fresh dill at your local market.
Can I make this soup vegetarian?
Yes! Swap the chicken stock for vegetable stock and add ½ cup white beans for extra protein. For richness, use coconut milk instead of heavy cream. The flavor will still be rich and satisfying, just with a plant-based twist. Add a splash of soy sauce to the stock for extra umami depth.
Why do the celery crowns need to be crispy?
The crispy texture is key to balancing the soup's creaminess. When fried properly, they provide a satisfying contrast that makes every bite exciting. For perfect results, fry them in olive oil over medium-high heat for 3-4 minutes per side
