Feel free to continue reading for more cooking tips.
Simply make a batch of mashed potatoes, once the potatoes are soft enough for mashing, drain them and leave to air dry.
Add milk and mustard into the pan to mash the potatoes with.
Whilst the potatoes for the mash are boiling, gently fry the onions on a medium low heat. Until soft & golden.
What cheese to use?
It is best to use a medium to mature cheddar to give a nice strong flavour to the mashed potato bake.
You can use any cheese, which is good for melting! Such as swiss, jack, gruyere, or gouda. The choice is up to you!
Mash to your desired texture, bare in mind most children like a nice smooth mash!
Grease your casserole dish before adding the cheesy mashed potatoes, this helps make it easier to remove when serving.
Pile the gooey, smooth cheesy mash into the greased casserole dish.
Add yet more cheese on top, you can use a different type to what you mashed in if desired? Top with onions and bake in the oven until golden on top.
For this cheese and potato bake recipe, we use crispy onions as a topping. See below for other mashed potato bake topping ideas.
Bake on the top shelf of a preheated oven (220°C/ 200°C fan / Gas mark 7 / 425°F) for about 15 minutes.
Can I make it ahead?
Yes, this cheese and potato pie is so easy to prepare ahead.
Keep it covered in the fridge until ready to reheat.
Cooking in a preheated oven at 220°C/ 200°C fan / Gas mark 7 / 425°F for about 20-25 minutes.
Alternative toppings for cheese and potato pie
Why not mix it up, try adding a topping of sliced tomatoes instead. Or add breadcrumbs to make a nice crispy golden topping.
If you have a fussy eater in the family, putting the onions on top, makes them easy to remove when serving!
Of course, if everyone likes onions, you could chop them smaller and mix them in with the mashed potato and cheese pie.
Alternatively, make the dish more filling and meaty by adding fried chopped bacon and onions in with the cheesy mash. It can then be served as a main meal with some vegetables.
The gloriously gooey cheesy mash can be served as it is or with any meat or poultry, vegetables, or baked beans.
We served ours up with air fryer sausages and petit pois peas. The kids would eat this every night if they had it their way!
Also makes a great addition to a roast dinner spread. Why not make our Easy Onion Gravy, to pour over the top!
How to store and reheat leftovers?
If you have any leftovers, simply store in the fridge for up to 3 days. Reheat the cheese and potato pie in the microwave until hot throughout.
