Prep and Cook Time

• Cooking Time: 45 minutes
• Total Time: 1 hour

Yield

Serves 4 generous bowls

Difficulty Level

Easy – Great for both beginner and experienced home cooks

Ingredients

• 4 large Yukon Gold potatoes, peeled and cut into 1-inch cubes
• 3 large leeks, white and light green parts only, cleaned and sliced into 1/2-inch rounds
• 4 tbsp extra virgin olive oil, divided
• 1 medium yellow onion, finely chopped
• 4 cups vegetable broth, low sodium
• 1 cup whole milk or unsweetened plant-based milk (for creaminess)
• 3 garlic cloves, minced
• 1 tbsp fresh thyme leaves (or 1 tsp dried thyme)
• Salt and freshly ground black pepper, to taste
• 2 tbsp unsalted butter (optional for richer finish)
• Fresh chives, thinly sliced (for garnish)
• Crusty bread or whole grain croutons, for serving

Instructions

1. Preheat your oven to 425°F (220°C). Toss the peeled potatoes and sliced leeks gently with 3 tbsp of olive oil, salt, pepper, and half the thyme leaves. Spread evenly on a rimmed baking sheet and roast for 30-35 minutes, stirring halfway through, until golden and caramelized at the edges.
2. While the vegetables roast, heat 1 tbsp olive oil in a large soup pot over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes, stirring occasionally.
3. Add the minced garlic and cook another minute until fragrant, careful not to burn it.
4. Remove the roasted potatoes and leeks from the oven and transfer them into the pot with the sautéed onions and garlic.
5. Pour in the vegetable broth and bring the mixture to a gentle boil. Reduce heat and simmer for 10 minutes to allow flavors to meld.
6. Using an immersion blender, carefully puree the soup until smooth but still retaining a slight texture. If you prefer a creamier texture, blend longer or strain through a fine sieve.
7. Stir in the milk and butter, if using. Adjust seasoning with salt, pepper, and remaining thyme leaves.
8. Heat the soup through on low for another 5 minutes, stirring gently to combine creaminess and roasted flavor.
9. Ladle into warm bowls and garnish with freshly sliced chives. Serve immediately with crusty bread or sprinkled croutons for added crunch.

Tips for Success: Balancing Creaminess and Texture

• Roasting is key: Don’t skip roasting the potatoes and leeks-this step develops a richer, deeper flavor that boiling alone can’t deliver.
• Keep some texture: When blending, leave a few small chunks to add a satisfying bite to this creamy soup.
• Milk options: Whole milk creates a luscious mouthfeel, but oat or almond milk works well for a lighter, dairy-free alternative.
• Use fresh herbs wisely: Stir in fresh thyme at the end to preserve its brightness; dried herbs work best during cooking stages.
• Make-ahead tip: Soup thickens upon standing-thin with extra broth or milk when reheating to restore smoothness.

Seasoning Secrets to Elevate Your Roasted Potato and Leek Soup

The magic lies in subtle seasoning that frames rather than masks the natural flavors. A pinch of nutmeg added just before blending adds warmth and complexity, while a touch of smoked paprika can evoke a subtle earthiness. For an unexpected burst, finish with a drizzle of truffle oil or a sprinkle of toasted pumpkin seeds. Remember to taste frequently and adjust salt gradually; richness is built layer by layer.

Serving Suggestions and Pairings for a Cozy Comfort Meal

This roasted potato & leek soup beautifully pairs with a crisp green salad tossed in lemon vinaigrette for refreshing contrast. For added heartiness, serve alongside roasted root vegetables or a simple boiled egg salad. Garnish with a dollop of crème fraîche or vegan sour cream for tang, and scatter thinly sliced scallions or crispy shallots on top for textural intrigue. Accompany with a warm baguette or seeded rye bread to mop up every last spoonful-comfort in every bite!

Q&A

Q&A: Roasted Potato & Leek Soup – A Cozy Twist on Classic Comfort

Q1: What makes roasted potato and leek soup different from traditional potato leek soup?
A1: Roasting the potatoes and leeks before blending adds a deep, caramelized flavor and a subtle smokiness that transforms this soup from simple comfort food into a cozy gourmet experience. Instead of just boiling the veggies, roasting concentrates their natural sweetness and creates a richer, more complex taste.

Q2: Why choose leeks for this soup? Can I substitute them?
A2: Leeks offer a milder, sweeter onion flavor that gently complements the earthiness of potatoes without overpowering the dish. While onions or shallots could work as substitutes, leeks bring a unique tenderness and subtlety that are hard to replicate, making them the star aromatic in this recipe.

Q3: What kind of potatoes are best for roasting and blending in this soup?
A3: Starchy potatoes like Russets or Yukon Golds are ideal. Yukon Golds, in particular, roast beautifully to golden perfection and yield a creamy texture when pureed. They strike a perfect balance of fluffy insides and slightly crisp edges when roasted, enhancing both the flavor and mouthfeel of the soup.

Q4: How do I achieve the perfect creamy texture without using heavy cream?
A4: The magic lies in the roasting and blending process. Roasting the potatoes and leeks reduces water content, concentrating flavors while preserving starchiness. Blending the soup with some reserved vegetable broth or a splash of unsweetened plant-based milk can create a velvety, luscious texture without any cream, making it lighter and dairy-free friendly.

Q5: Can I make this soup vegan? What are some suitable plant-based alternatives?
A5: Absolutely! Swap butter for olive oil or vegan margarine when roasting and sautéing your vegetables. Use vegetable broth as your base, and add unsweetened almond milk, oat milk, or coconut milk to the blended soup to enhance creaminess. This approach maintains the cozy essence while keeping it 100% plant-based.

Q6: Are there any herbs or spices you recommend to enhance this soup?
A6: Fresh thyme and a hint of bay leaf during roasting elevate the soup with earthy, aromatic depth. A pinch of smoked paprika or nutmeg can also add warmth and dimension. Finish with chopped chives or parsley for a fresh, vibrant contrast that brightens the bowl.

Q7: How should I serve roasted potato and leek soup for maximum coziness?
A7: Ladle it into rustic bowls and crown with a drizzle of good-quality olive oil or a swirl of herb-infused coconut cream. Pair with crusty artisan bread or garlic-toasted slices for dipping. A sprinkle of crunchy roasted pumpkin seeds or toasted breadcrumbs on top offers delightful texture contrast, perfect for snuggling up on chilly evenings.

Q8: Can this soup be prepared in advance? How do I store it?
A8: This soup is a great make-ahead meal! Store it in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stove, adding a splash of broth or plant-based milk if it thickens too much. It also freezes well, so double the batch and freeze portions for convenient, comforting meals anytime.
