This recipe is all about letting simple ingredients shine, with leeks slowly braised until tender and naturally sweet. A cool, tangy layer of crème fraîche and a touch of lemon keep things fresh, while golden sourdough breadcrumbs and savoury Parmesan add just the right amount of crunch. It’s comforting, elegant, and the kind of dish that quietly steals the show on the table.
Leeks
4–5 large leeks, trimmed and halved lengthwise
2 tbsp olive oil or butter
1 cup vegetable or chicken stock
1–2 tsp lemon juice
Salt and freshly cracked black pepper
Crème Fraîche Layer
½ cup crème fraîche
Zest of ½ lemon (optional)
Salt and pepper, to taste
Sourdough Breadcrumb Topping
1½ cups sourdough breadcrumbs
2 tbsp olive oil or butter
¼–⅓ cup grated Parmesan
1 small garlic clove, finely grated (optional)
Fresh thyme or parsley (optional)
Prep the leeks: Clean thoroughly, separating layers to remove grit. Pat dry.
Sear the leeks: Heat olive oil or butter in a wide pan over medium heat. Place leeks cut-side down and cook until lightly golden, about 4–5 minutes. Flip, season with salt and pepper.
Braise: Add stock and lemon juice. Liquid should come about halfway up the leeks. Bring to a gentle simmer, cover, and cook 15–20 minutes until very tender. Uncover for the last few minutes to let the liquid reduce slightly.
Prepare the crème fraîche: In a small bowl, stir together crème fraîche, lemon zest (if using), salt, and pepper. Set aside.
Make the breadcrumb topping: Heat olive oil or butter in a skillet. Add breadcrumbs and toast until golden and crisp. Stir in garlic, Parmesan, herbs, salt, and pepper. Remove from heat.
Assemble: Spread a generous layer of crème fraîche on the bottom of a serving platter. Arrange the leeks on top, spoon a little of the reduced braising liquid over them, then finish with the sourdough breadcrumbs.
