Ingredients Notes
To make this recipe you will need the following ingredients:
- White Potatoes: Create a creamy, fluffy mash that forms the base and top layer of the casserole. Choose a floury potato such as Maris Piper, Russet or Yukon Gold for the best texture.
- Sweet Potatoes: Add natural sweetness, colour and extra nutrition, creating a delicious contrast with the savoury topping.
- Back Bacon: Adds a smoky, salty crunch to the top of the casserole. Trim any visible fat before chopping.
- Cheddar: Melts into a delicious golden topping. A mature Cheddar gives the best flavour, meaning you don't need to use a large amount.
- Eggs: Help bind the mashed potato layers together so the casserole slices and serves neatly.
- Chicken or Vegetable Stock: Used to cook the potatoes, adding much more flavour than cooking them in plain water. Use vegetable stock to keep the dish vegetarian (omitting the bacon).
- Fresh Chives: Sprinkle over the finished casserole for a fresh burst of flavour and colour.
- Salt and Black Pepper: Season the potato layers to bring out all the flavours.
Once you've gathered all the ingredients and prepared them accordingly, you're all set to create this easy and delightful recipe.
See the recipe card for specific quantities and instructions.
Variations and Substitutes
There are plenty of ways to adapt this layered mashed potato casserole to suit your tastes or what you have available.
- Use all white potatoes: Skip the sweet potatoes and use only white potatoes for a more traditional mashed potato casserole.
- Use all sweet potatoes: If you love their natural sweetness, replace the white potatoes with sweet potatoes instead.
- Try a different vegetable layer: Swap the sweet potato layer for mashed carrots, pumpkin, swede (rutabaga) or butternut squash for a delicious twist. These all pair beautifully with the cheesy topping.
- Make it vegetarian: Omit the bacon and use vegetable stock instead of chicken stock.
- Try a different cheese: Reduced-fat mozzarella, Red Leicester, Gruyère or a reduced-fat cheese blend all work well in place of Cheddar.
- Add herbs: Mix chopped parsley, thyme or rosemary into the mashed potatoes for extra flavour.
- Add vegetables: Layer in cooked spinach, sautéed leeks or caramelised onions between the potato layers.
- Change the topping: Sprinkle over a little grated Parmesan with the Cheddar for an extra golden, crispy finish.

Storing, Freezing and Reheating
Storing
Allow the casserole to cool completely, then cover tightly or transfer to an airtight container. Store in the refrigerator for up to 3 days.
Freezing
This casserole freezes well. Portion into freezer-safe containers or wrap the whole cooled casserole tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat individual portions in the microwave until piping hot, or warm the casserole in a preheated oven at 180°C (160°C fan/350°F) for 20-25 minutes, or until heated through. If reheating from frozen, thaw first for the best texture.
