Cooks in just 15 minutes and so easy to make into Instant Pot Root Vegetable Mash.

When I last lived in England I used to love going fruit and vegetable shopping at our local market.

It was back in the year 2007 and Kyle was 6 years old and I would go grocery shopping after I had dropped him off at school.

It was a 10-minute walk to the market and the local village. I would go to Iceland first as they did free home delivery on orders of £25 and I was a non-driver, so it was a godsend.

Then to my favourite small freezer shop and then finally to the market.

It was a market with a lovely atmosphere and the smells were incredible. People selling homemade pork pies, homemade sausage sandwiches and lots of market traders selling home goods.

I loved the fruit and veg stall and it often had fruit and veg that was better quality than what you got at the supermarket.

Though I would always end up buying lots of root vegetables as I ALWAYS loved them. I would get potatoes, swede (what us Brits call Rutabaga), carrots and of course parsnips.

Then I would take them home and make a veggie bake with them (you can get my veggie bake recipe here).

But when I was at the market stall there would always be a random elderly person telling me that apart from soup the best thing in the world to make with root vegetables is root vegetable mash.

Here we are in 2018 and 11 years later and my 6-year-old is soon to be 17 and I am finally getting around to making root vegetable mash.

But unlike 11 years ago we now have Instant Pot Root Vegetable Mash.

Times have changed, and it no longer takes what feels like all day to make a delicious lunch and here we are with our Instant Pot Pressure Cookers.

We have the 6 litre (and also own the 8 litre) Instant Pots and use them all the time for our root vegetables. As you know root vegetables are so hard and thick, they can take forever to cook!

When we made our Instant Pot Root Vegetable Mash we used:

  • White Potatoes
  • Sweet Potatoes
  • Carrots
  • Swede/Rutabaga
  • Parsnips

But you can make your Instant Pot root vegetable mash your own by adding what you have in your fridge or what is in season.

Other delicious Instant Pot Root Vegetable Mash ideas include:

  • Beetroot
  • Baby Potatoes
  • Celery
  • Turnips
  • Butternut Squash

Treat the quantities of your Instant Pot root vegetable mash like the quantities you were using if making traditional white potato mash.

But unlike just doing it with potatoes you have a beautiful mix of flavours and it is really easy for when you have leftover root vegetables that need cooking.

Don’t feel like your Instant Pot root vegetable mash is a failure unless you have lots of different vegetables, 3 or more is fine. Though what we did was go with 5 vegetables for our mash.

As you can see below we chopped them all up into a big bowl first before placing them in the Instant Pot:

That way we could make sure we had enough as sometimes it feels like you peel loads of veg and then are left with a tiny bit of mash.

  • Peel and dice all of your vegetables into similar medium sized chunks.
  • Place a cup of water in the bottom of your Instant Pot inner pot and then pour the vegetables on top.
  • Season the vegetables with salt, pepper and rosemary.
  • Set the Instant Pot valve to sealing and cook for 15 minutes on manual.
  • Manually release pressure when it beeps and drain the vegetables.
  • Season the vegetables with extra salt and pepper, add the coconut butter and mash until no lumps are left.


Its important when making Instant Pot root vegetable mash that the vegetables are of similar size. This helps to make sure that all vegetables are well cooked for making mash with and that some are not under cooked.
Add a bit more rosemary at the end of cooking if you think it needs it. As the Instant Pot can sometimes strip away flavour. If you don’t like coconut butter you could also use olive oil or our favourite butter.
