Leeks are one of those vegetables that completely transform in the oven — what starts out mild and a little grassy becomes sweet, silky, and deeply caramelized at the edges. This simple roasted preparation lets that natural flavor shine with nothing more than good olive oil, a pinch of heat, and a bright squeeze of fresh lemon at the end. It's the kind of side dish that looks far more impressive than the effort involved, which is always a win. For anyone navigating a yeast-free lifestyle, this recipe is a natural fit — every ingredient is whole and straightforward, with zero hidden fermented additives or yeast-derived seasonings to worry about. The two-stage roasting method is the real secret here: starting cut-side down builds that gorgeous golden crust, then flipping lets the layers soften all the way through without going mushy. A scatter of fresh parsley at the end adds a pop of color and freshness that makes the whole platter feel restaurant-worthy. Serve it alongside roasted chicken, grilled fish, or honestly just on its own with some crusty bread.

Preheat the oven to 425°F (220°C). Line a large baking sheet with parchment paper.
Trim the root ends and dark-green tops from the leeks, leaving only the white and light-green parts. Halve each leek lengthwise, then rinse under cold running water, fanning the layers to remove any grit. Pat thoroughly dry with paper towels.
