Nutrition: per serving
Heat oven to 200C/180C fan/gas 6. Steam the leeks for 10 mins or until just tender, then drain and pat dry. Arrange in an ovenproof dish and spoon over the cheese sauce.
Mix the breadcrumbs, cheese, lemon zest and thyme together. Scatter over the leeks and bake for 15-20 mins, until the leeks are cooked and the crumbs have turned golden and crisped up.
