Leeks Vinaigrette with Burrata Cheese and Mustard

This sophisticated leeks vinaigrette with burrata cheese and mustard elevates the humble leek into a truly elegant vegetarian starter. By slow-braising the leeks in a savoury lemon and thyme broth, they develop a meltingly tender texture and a deep, caramelized sweetness that contrasts beautifully with the cold, creamy cheese. The addition of a sharp mustard dressing and crunchy, spiced breadcrumbs provides a wonderful balance of textures and a zesty finish that wakes up the palate.

Ideal for a weekend lunch or as a polished first course for a dinner party, this dish can be partially prepared in advance to save time. The vibrant green of the leeks and the fresh parsley make for a stunning presentation on the plate. Serving this with a crisp glass of dry white wine helps to cut through the richness of the burrata, making it a well-rounded and satisfying seasonal favourite.
