Greek Yogurt Mashed Potatoes is an easy and deliciously creamy healthy mashed potatoes recipe you can make ahead. Learn about the best potatoes for mashing, how to add lots of flavour, and why I love to make mashed potatoes with skin on for an extra nutritious side dish!
For the longest time, I felt like mashed potatoes wasn’t really something anyone needed a recipe for. And then I had really good mashed potatoes for the first time and my mind was blown.
I asked our host what kind of voodoo he was practicing to make the most amazing, other-worldly melt-in-your-mouth delicious potato dish that had ever crossed my lips, and was subjected to a 30-minute lecture about the best potatoes for mashed potatoes, various mashing techniques, and the merits of leaving the skin on or taking it off.
But the tl;dr answer? Butter. Lots and lots and lots of butter. It reminded me of this episode of Top Chef I’d seen in which one of the contestants made a mashed potato recipe from some French restaurant which was half potato and half butter by weight. Half butter! By weight!
Friends, this is not that. I’ve taken what I learned about how to make the best mashed potatoes, and combined it with what I know about nutrition and food science in order to make this crazy delicious healthy mashed potatoes recipe: Greek Yogurt Mashed Potatoes.
What goes into Greek Yogurt Mashed Potatoes?
This healthy mashed potatoes recipe has only a handful of ingredients! You’re going to want to grab:
- Potatoes –> I hope you were sitting down for that one. We’ll discuss potato varietals below.
- Greek yogurt –> Surprise!
- Vegetable broth –> Building in flavour!
- Butter –> But just a little bit!
- Chives –> Not mandatory, but if you want to be fancy then throw ’em in!
- Salt and pepper –> Because of course.
How do you make healthy mashed potatoes?
Ok, here’s the deal. We’re going to replace all of the cream and most of the butter with Greek yogurt and a bit of vegetable broth. We’re actually going to cook the potatoes in the broth, which adds flavour before we’ve even started mashing.
So, you’ll dice up your potatoes and add them to a pot with the vegetable broth. The broth won’t cover the potatoes, but that’s ok. Bring to a boil, then cover and simmer until the potatoes are fork tender.
Then, drain the potatoes, but (this is important!) make sure you RESERVE THE BROTH.
Now mash your spuds. I use an old-school potato masher rather than a ricer, because I like to make mashed potatoes with skin on. More on that below.
Once mashed, add the butter, Greek yogurt, and salt and pepper to taste. If you feel like your mashed potatoes are on the dry side, add a little bit of the reserved broth. It’s full of flavour and nice and thick with potato starch, so it’s the perfect thing to mix in.
Then, top your potatoes with chives, green onions, or whatever else you’re into, and serve!
Can I make these mashed potatoes in advance?
You bet you can! Simply re-heat in the microwave or in the oven. If they seem a bit dry on re-heating, you can add a little bit of your reserved vegetable broth back in. See? Moisture AND flavour. Boom!
What are the best potatoes for mashed potatoes?
Excellent question! While many people think that a floury potato varietal like Russet are the best potatoes for mashing, when I’m making healthy mashed potatoes I prefer to use a waxy varietal like Yukon Gold.
Why? The drier, fluffier Russet potatoes will soak up a TON of liquid, and you keep having to add more butter and more cream to get that perfect mashed potato texture. Waxy potatoes like Yukon Gold not only have a great, buttery flavour to begin with, they require less liquid and fat to be added to the mash.
Should I leave the skin on mashed potatoes?
This is sort of a matter of personal preference, but when it comes to making healthy mashed potatoes I am firmly on team skin. I also really love making red skin mashed potatoes, but I couldn’t find any on the day I took these photos!
When you make mashed potatoes with skin you leave a ton of nutrients in the dish as much of a potato’s nutrition is concentrated in the skin. Leaving the skin on also significantly increases the dietary fiber in these Greek Yogurt mashed potatoes, which is hella good for your gut.
Also, I am lazy and seriously can not be bothered to peel a bunch of potatoes that are just gonna get mashed up. You do what you will.
What kind of yogurt is best for mashed potatoes?
Have you ever eaten Greek yogurt in Greece? I have. It’s like 10% fat and so thick you could stand up a spoon in it. That 0% fat “Greek yogurt” is a travesty, I tell ya.
What I’m saying is, please go and find yourself some full-fat Greek Yogurt or other Balkan style yogurt for these healthy mashed potatoes. Remember that we’re replacing a butt-load of butter and cream here, and a full-fat yogurt is going to result in much more delicious mashed potatoes than low-fat or fat-free.

Hey Nutrition Lady, are potatoes healthy?
You bet they are! Potatoes are a great source of vitamin B6, which does all kinds of important things, like building new cells in your body. B6 is also needed for the creation of amines, like serotonin, melatonin, epinephrine, and norepinephrine that help to regulate mood, sleep, and stress, respectively.
Diets rich in vitamin B6 are attributed to lower rates of heart disease. Also, B6 is vital for the breakdown of gylcogen – the form in which sugar is stored in our body – into usable energy.
Potatoes are also a good source of potassium, copper, vitamin C, manganese, phosphorous, niacin, and dietary fiber. But! Most of the fiber content is in the skin of the potato, so leave the skin on (like in these Greek Yogurt Mashed Potatoes!) for all of the important benefits of ingesting fiber.
Good to know – potatoes are a member of the nightshade family (along with tomatoes, bell peppers, and eggplants), which some people have adverse reactions to. It’s also worth noting that potatoes are on the ‘dirty dozen’ list of foods to buy organic whenever possible.
