Instructions
In medium saucepan, heat oil and fry onions and carrots until soft. Add flour, creating a paste, cooking for one minute. Add ketchup, beef stock, Worcestershire sauce, thyme, salt and pepper, bringing to a boil. Simmer 2-3 minutes, then add ground beef or turkey, simmering until heated through. Add to foil disposable casserole.
In a separate bowl, combine mashed potatoes with butter and cream, then top meat mixture with it. Cool and freeze. If you have a small family, split into two casseroles instead of one.
On serving day
Thaw overnight in fridge or 4-5 hours at room temperature. Brush top with egg (optional). Preheat oven to 425F and bake for 20-30 minutes (if you split into two casseroles, cooking time may be shorter).
