Elevate Your Dinner with the Perfect Pair
There’s something quietly magical about the marriage of humble potatoes and elegant leeks. On their own, potatoes are comforting and familiar. Leeks, with their delicate onion-like sweetness, feel refined and special. But together, roasted until golden and crisp, they create a side dish that’s greater than the sum of its parts.
This pairing isn’t just delicious; it’s steeped in history. In Wales, leeks have been a national symbol since the 7th century, and they’ve long been paired with potatoes in rustic dishes like cawl, a hearty stew that sustained families through cold winters. Meanwhile, in French kitchens, poireaux vinaigrette and gratin dauphinois show how leeks and potatoes have been elevated to elegant fare for centuries.
Our roasted potatoes with leeks recipe honors that legacy: simple ingredients, transformed by fire into something deeply satisfying. The potatoes crisp at the edges while staying fluffy within, and the leeks caramelize into sweet, silken ribbons. It’s the kind of dish that feels equally at home on a weeknight table or a holiday spread, and it’s easier to make than you think.

Essential Ingredients and Why They Matter
You don’t need a long list of ingredients, but each one plays a vital role.
The Potato Choice
Go for Yukon Gold or Russet potatoes. Yukon Golds offer a creamy interior with a naturally buttery flavor, while Russets deliver maximum crispiness. Cut them into even chunks so they roast uniformly.
The Leeks
Choose firm, bright green-and-white leeks with no slimy spots. Because leeks grow in sandy soil, they trap grit between their layers. To clean them properly, slice them, then swish them in a bowl of cold water, letting the dirt sink to the bottom before lifting them out.
Fat & Seasoning
Use extra-virgin olive oil or clarified butter for richness and high-heat stability. Season generously with kosher salt, freshly cracked black pepper, and fresh thyme or rosemary. These herbs add earthy depth that complements both the potatoes and leeks beautifully.

Step-by-Step Guide: How to Achieve Perfect Texture
The secret to this dish isn’t just roasting; it’s technique.
Preparing the Leeks
Slice leeks into ½-inch rounds. Place in a large bowl of cold water, swirl vigorously, then let sit for a minute. Lift them out (don’t pour; they’ll carry the grit back in). Pat dry with a clean towel, moisture is the enemy of crispness.
The Parboil Trick
This is the game-changer. Boil your potato chunks in salted water for 6–8 minutes until just tender at the edges but still firm in the center. Drain well, then return to the hot pot over low heat for 1–2 minutes to steam off excess moisture. For extra crispness, shake the pot gently to rough up the edges; this creates more surface area to crisp.
The Roasting Method
Preheat your oven to 425°F (220°C). Toss the parboiled potatoes with oil and half the herbs. Spread in a single layer on a rimmed baking sheet. Roast for 20 minutes, then add the leeks, tossing gently to combine. Return to the oven for 15–20 minutes more, until potatoes are deeply golden and leeks are soft and lightly caramelized.
Pro Tip: Don’t add the leeks too early; they burn faster than potatoes. Adding them halfway ensures they stay sweet and tender, not bitter.

Troubleshooting and Flavor Variations
Troubleshooting
“My potatoes aren’t crispy!”
→ They weren’t dry enough after parboiling. Always steam-dry and rough up the edges.
→ Your oven wasn’t hot enough. Stick to 425°F or higher.
→ You overcrowded the pan. Give them space to breathe!
Flavor Variations
- Cheesy twist: Toss with grated Parmesan in the last 5 minutes.
- Smoky depth: Add crumbled cooked bacon or pancetta.
- Bright finish: Drizzle with white wine vinegar or lemon juice before serving.
FAQ: Your Questions on Roasting Leeks
Can I use frozen leeks?
It’s not recommended. Frozen leeks release a lot of water when roasted, which leads to steaming instead of caramelizing. For the best texture and sweet, tender flavor, always use fresh leeks; just be sure to clean them thoroughly to remove any grit.
What is the best way to store leftovers?
Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. To restore crispiness, reheat in a 400°F (200°C) oven or air fryer for 5–7 minutes; avoid the microwave, as it makes the potatoes soggy.
Do potatoes and leeks go together?
Absolutely! Their flavors are a classic pairing: earthy, buttery potatoes balance the mild, onion-like sweetness of leeks. This combo is popular in French and British cooking (think potage Parmentier or rustic roasts) and works beautifully in both simple and elegant dishes.
Is it necessary to boil potatoes before roasting?
For truly crispy roast potatoes, yes, parboiling is key. It softens the interior and roughs up the surface, creating more area for browning. Skipping this step often results in tough exteriors and undercooked centers.
What is the secret to crispy roast potatoes?
Three things:
Parboil first to fluff the edges.
Dry them well before roasting (moisture is the enemy of crispness).
Roast at high heat (425°F/220°C) with enough space between pieces so they crisp instead of steam.
Can you roast leeks with other vegetables?
Yes! Leeks pair wonderfully with carrots, fennel, mushrooms, or Brussels sprouts. Just add them at the right time; since leeks cook faster than root vegetables, add them halfway through roasting to prevent burning.
