Shallow oven proof dish
Le Creuset Cast Iron Rectangular Oven Dish
At £95, the Le Creuset Cast Iron Rectangular Oven Dish, Volcanic, 30 cm (Amazon.co.uk) is not cheap, however it's probably my favourite oven dish and comes highly recommeded. It's just the right size for small casseroles, pasta bakes, batters, toad-in-the-hole, pot roasts and the like.
Perfect for 2 people.
