Mashed potatoes are always a hit in my home. My little daughters absolutely love them, they go with many different meals and they’re great for topping things like slow cooker cottage pie filling and serving with beef casserole when I want to pad it out a little more. This pressure cooker mashed potatoes recipe is super simple.

It takes just a couple of minutes to prepare and will cook itself while I’m making something in the air fryer to accompany it.

What I love about making mashed potatoes in the pressure cooker is that I don’t have to watch a pot on the hob. Perfect when I’ve got a two year old and a little puppy running around most evenings.

The pressure cooker that I use is part of the features of my Ninja Foodi OL750UK, which I absolutely love. You should find the timings work for other pressure cooker models too, as they’re all pretty similar. If you’re worried you can always add a little more stock, but I do find there is always some left once I’ve cooked these potatoes for mashing in the pressure cooker.

I’ve tried out quite a few different ways to make mash in the last year or two. We love all of them – air fryer mashed potatoes, slow cooker mashed potatoes and of course just regular mash too. I love to use leftover mashed potatoes for air fryer mashed potato balls too, which are great to serve with air fryer chicken tenders or mini chicken fillets cooked in the air fryer when I want a super simple tea.

I’ve got a ton of air fryer vegetable side dishes that would work great with mash too, so do check those out, and don’t forget about beef gravy, onion gravy and air fryer onions too. Perfect served with mash.

Mashed potatoes work brilliant as part of a yummy roast dinner when served with sage and onion stuffing, slow cooker whole chicken and Ninja Foodi roast potatoes. We start eating roasts weekly from November time, right around until the Spring, and I love having lots of variety every week.

Ingredients for making pressure cooked mashed potatoes:

1kg white potatoes

Salt

300ml stock

50ml whole milk or cream (heavy cream or double cream work well)

30g butter or garlic butter for garlic mashed potatoes

A blue bowl containing pressure cooked spaghetti, air fryer meatballs and tomato sauce topped with cheese

Method for making pressure cooker mash:

Peel your potatoes and chop into bitesize pieces.

Wash them thoroughly.

Add to the pressure cooker pot, without the steamer basket.

Add 300ml of stock. I use vegetable stock usually.

Add salt (depending on the stock you’re using you may be able to skip this).

Cook on the pressure cooker high setting for 8 minutes, using the quick release setting for the steam release.

You want to quick release the pressure, either manually or using your machine setting, to avoid overcooking the potatoes.

Check your potatoes are done by pricking with a fork. You want them to be fork tender, which they should be after 8 minutes pressure cooking.

Once they are cooked you can add milk or cream and butter. Usually there will be a little stock left, no need to drain this away just mash it inside the potatoes for a creamy mash.

Then use your potato masher of choice to mash. I personally love to use a *Masha as I find it gives fantastic results.

Serve with your dinner and enjoy!

Do you need to boil the potatoes before pressure cooking?

No. The pressure cooker will take your potatoes from raw, and rock hard, to soft, fork tender and perfect for mashing.

This is a really low effort recipe which is fantastic.

How long does it take to make mashed potatoes in the pressure cooker?

By the time your pressure cooker has reached full pressure, begun cooking, and released the steam, you’re looking at around 13-15 minutes in total, from start to finish. Obviously this is on par with boiling potatoes really, not much faster, however, you won’t have to watch the hob or worry about it boiling over, leaving you free to get one with something else.

Can you make this mash with the skin on?

Yes, the skins will be really render, and simple to just mash into the potato if you like a more rustic style mash.

Want to use a different type of dairy in your mash?

You can replace the milk or cream with cream cheese or sour cream if you’re wanting a slightly richer mash. Follow the same quantities and you’ll have a tasty mash that is perfect for piping.

Which potatoes work best for making mash?

I personally love to use either King Edward or Maris Piper when I’m making mash. Yukon Gold or Russet potatoes work great too, if you can find them, and I’m reliably informed that Desiree are lovely for mash.

If you’re on a tight budget, or just like to keep your food costs lower, then the standard white potatoes you find in many UK stores will also work great. No need to splash out for a special bag, as a lot of it is just nice branding, particularly during the ripest harvest months of June – September.

Can you freeze this mash potato once cooked?

I do, and it works great. I love to use it on the top of dinners. Also, I will freeze it flat in a ziplock bag and then I can just portion off a small amount when I want a simple lunch or dinner just for myself.

What to serve with mashed potatoes?

I love a nice hearty dinner, often with chicken, beef or pork as the main protein source. Slow cooker roast beef, Ninja Foodi pulled pork, slow cooker sausage cassoulet and air fryer sausage meatballs all work great and are some of the favourites in my home.

For me I also love to mix it up, when I’m feeding a crowd, by making other air fryer potato side dishes to go alongside this mash. It’s a great way to give lots of variety, and make a meal more substantial, without spending much.

I usually cook air fryer vegetables while making mash, as they’re cheap, simple and quick. Some of the favourites in my home are air fryer corn on the cob, air fryer tenderstem broccoli, air fryer cauliflower cheese, air fryer green beans and air fryer onions.

Tomato ketchup is always a hit with my daughters too, and they love it with mash.
