This root vegetable mash (rotmos) is an extremely comforting and delicious side dish with natural sweetness and buttery flavor from cooked carrots, sweet potatoes and parsnips.

Of course, we’ll add some milk, sour cream and butter to it as well. Just as we always do with mashed potato dishes.

Although, it’s really not necessary, since traditionally root vegetable mash is made without any added milk or butter.

These root vegetables are so flavorful when cooked that they can stand alone. But, we don’t mind adding the extra richness to it with some added ingredients that make it even more creamy. Especially since we most often prepare this for special occasions and we don’t mind a little extra indulgence.

Although lately, we make it as often as possible in our regular rotation, because it is so good and the perfect way to get more healthy root vegetables on your plate. It’s so easy and it just goes so well with every main course.

It’s a forgiving dish and so easy to make substitutions, with other root vegetables and in other ratios of root vegetables. If you like more of one type of root vegetable, say parsnips, you can easily just add more of those.

We really like the combination of carrots, parsnips and sweet potatoes in this root vegetable mash (rotmos in Swedish).

Rutabagas and radishes can also be incorporated into the mix if you have them. You can feel free to customize this recipe to your preference since all of the root vegetables will come together beautifully in this mash.

We love sweet potatoes in ours but you can make this with some yellow, white or red potatoes instead of sweet potatoes, if you prefer.

However you choose to prepare it, you’re in for a treat!

What is Rotmos?

Rotmos is Swedish for root mash and is literally mashed root vegetables. The dish originates from Sweden and is usually made from rutabaga, potatoes and carrots. In addition, the traditional rotmos does not contain milk or sour cream.

However, we adapted the recipe to exchange the rutabaga for parsnips and the potatoes for sweet potatoes. We also added milk and sour cream to create a smooth and creamy mash that has a sweet and buttery taste.

Start by peeling all the vegetables and cut the carrots and parsnips into 1-inch pieces. Cut the sweet potatoes in half and add everything to the Instant Pot.

STEP 2 – Add Water and Pressure Cook

Add enough water to just cover the vegetables. Then secure the lid on the Instant Pot and set the pressure valve to “sealing”. Pressure cook on HIGH pressure for 5 minutes at normal temperature. Quick release when the pressure cycle is completed.

You don’t necessarily need an Instant Pot to cook this dish. It can be made just as easy on the stovetop using a large pot. Just follow the same steps as above but adjust the cook time to let the vegetables boil for 10 minutes instead. The rest of the steps are all the same.

How to Reheat Mashed Root Vegetables

The mashed root vegetables can easily be reheated in the oven at 350°F for 5-10 minutes, on the stovetop in a sauce pan on medium low temperature for 5 minutes, or in the microwave on high power for 2 minutes. You can also reheat it in your Instant Pot using the Sauté function for 5 minutes.

In any case, add a few tablespoons of milk when reheating, if the root vegetable mash seems too dry.

Storage Tips for Root Vegetable Mash (Rotmos)

You can keep mashed root vegetables in the fridge for up to three days. Just ensure that the mash is tightly sealed in an air tight container.

Any leftovers can also be frozen for several months in a freezer safe container.
