Health benefits of potatoes
Whilst we do love a good sweet potato mash, you just can't beat chips made with white potatoes. White potatoes have so many nutrients in them, they really shouldn't get a bad reputation.
They are low in fat (although adding the cream and butter does change this), sodium and cholesterol, they have nearly half of your daily vitamin C and they are a great source of potassium - even more than a banana. They are full of fibre and magnesium, and they are filling too. On top of this, they are also suitable for almost any diet, from vegan to gluten free. I am not sure what more you could want!
All the flavour in these make ahead mashed potatoes comes from the cream and butter. Then you could add some flavour with some mature cheddar or cream cheese stirred in at the end. However, there are a few other flavour options as well.
You could add in some rosemary or thyme, or if you wanted a summer version to these, then you could add basil and lemon. Parmesan is also a good alternative to cheddar.
If you like a kick of heat in your food, then you can stir in some dried red chilli flakes. Want to make them really indulgent? When you add the cheese, stir in some cooked chopped bacon. Next. Level. Potatoes.
For something a little different, pesto stirred in to mashed potatoes is really good. So are caramelised onions.

Make ahead and store
The whole appeal of this recipe is making it in advance and then reheating it when you needed, so here are the different ways that you can do that.
Fridge: Leave the mashed potatoes to cool and transfer to a bowl. Cover tightly and refrigerate. This will keep in the fridge for 2 days.
Freezer: You might be thinking "can I freeze mashed potato?", the answer is yes! If you are going to freeze mashed potatoes, then add the cream and butter first and freeze. Then add a little more butter and cream when reheating. So, make the mashed potatoes, with butter and cream, and once cooled put them in freezer bags and lay flat in the freezer. You can do this up to a month in advance.
Defrost: You can defrost at room temperature and it will take about 5 hours.
Reheat: When you are ready to serve the potatoes, put the cream and butter into a pan. Gently heat until the butter has melted, about 2 minutes. Stir in the potatoes, continuing to heat gently.
If you are reheating frozen potatoes that already have the cream and butter in, then you can reheat it in the microwave for 2-3 minutes and stir in some cream and butter before serving.
Frequently Asked Questions
We use a really sturdy potato masher to mash our potatoes, as we are fine with a few smaller lumps. However, if you like your mashed potatoes super smooth, then get yourself a potato ricer. This gives you really smooth and creamy potatoes, and makes sure that they aren't overworked like they would be with a masher, which is key if you are going to use leftovers to make gnocchi.
Whilst leftovers of this side dish is rare in our house, if you do have any leftovers then there are a few really good options to make sure that nothing goes to waste. You can make leftover mashed potato cakes by mixing them with an egg and a little flour, then forming into patties and frying. Or, you can make our Leftover Mashed Potato Gnocchi.
You will need to swap the cream and butter for plant based versions.
We go with 200g/7oz of potatoes per person. Adults might have a little more and kids might have a little less.
If you don't want to cook the mashed potato ahead of time, but just prepare it, then you could peel and chop the potatoes and then keep them in a pan of cold water in the fridge until the next day.
• Cut all the potatoes to the same size to ensure that they all cook the same.
• If you prefer chunky mashed potatoes, then don't over mash them. We like ours really creamy and fluffy.
• We find using a potato masher is fine, however if you like really smooth potatoes then you can use a potato ricer.
• Add salt and pepper at the end to season, that way you can taste them and add more if you prefer.
• You don't have to peel the potatoes, and leaving the skin on will save even more time and still keep the fibre.
