This comforting and flavorful Mary Berry Cottage Pie with Grated Double Potato Topping features a rich, slow-cooked beef filling topped with a golden, cheesy crust made from both sweet and white potatoes.

How To Make Mary Berry Cottage Pie with Grated Double Potato Topping
- Preheat oven: Set to 160°C/140°C Fan/Gas 3.
- Cook base: Sauté onions, celery, and carrot in oil. Add beef and brown thoroughly.
- Build sauce: Sprinkle in flour, then stir in Port and hot stock until slightly thickened. Add tomato paste, Worcestershire sauce, oregano, and bay leaves.
- Bake filling: Cover and bake for 1–1½ hours until the meat is tender. Season, remove bay leaves, stir in gravy browning (if using), and spoon into a dish.
- Boil potatoes: Cook both types of potatoes in their skins until just tender. Cool, then peel.
- Grate and top: Coarsely grate potatoes, mix with melted butter, season, and spread over the filling. Sprinkle with cheese.
- Final bake: Increase oven to 200°C/180°C Fan/Gas 6. Bake for 30–35 minutes until golden and bubbling.
- Serve: Hot, with your favorite green vegetable.

Recipe Tips
- Grate, don’t mash: The grated potato topping gives more texture than traditional mash.
- Use Port or red wine: Both add richness to the beef sauce.
- Cool potatoes before grating: They’ll hold their shape better and grate easily.
- Prepare ahead: Can be assembled (without baking) up to 8 hours in advance.
- Freeze smart: Freeze the meat base separately and top with fresh potato when ready to cook.
What To Serve With Cottage Pie
Serve with green beans, peas, or sautéed kale. For added indulgence, add a dollop of horseradish or a spoonful of pickled red cabbage.
How To Store Cottage Pie
Refrigerate: Store leftovers covered in the fridge for up to 3 days. Reheat until piping hot throughout.
Freeze: Freeze the filling only (without topping) for up to 3 months. Add fresh grated topping when ready to bake.
