Instructions
Trim and clean the leeks. Slice them in half lengthwise, then cut into 3-inch pieces. Rinse well to remove dirt.
Heat oil in a large skillet over medium heat. Add leeks cut-side down. Cook for 3–4 minutes until lightly golden.
Flip leeks, season with salt, pepper, and thyme.
Add broth and bring to a gentle simmer. Cover with a lid.
Braise for 15–20 minutes until the leeks are soft and the sauce has reduced.
Uncover and add lemon juice if using. Let cook 2–3 more minutes to thicken slightly.
Serve warm with sauce spooned on top.
