Lamb is one of the loveliest meats when slow-cooked, its fibres and fats breaking down into buttery tenderness. Pasture-raised lamb contains valuable amounts of conjugated linoleic acid, a health-supportive fatty acid that has been shown to promote fat loss — so it’s worth buying organically raised, 100 per cent grass-fed lamb wherever possible. Enjoy its benefits in this super-comforting casserole.
