If you’re looking for a fuss-free healthy version of mashed potatoes, I think you’ll be very pleased with my recipe. These lighter mashed potatoes are made with naturally buttery yukon potatoes. I boil the potatoes with whole garlic cloves, and then mash them with sour cream, vegetable broth and a tad of butter. They come out so creamy, fluffy and utterly delicious! This classic side dish gets a mini makeover for the major Thanksgiving dinner!

Are mashed potatoes healthy?

So wait, we’re making healthy mashed potatoes. But you might be asking, are mashed potatoes even healthy? Potatoes don’t really show up on many diet meal plans. And I think that’s mostly because of how potatoes are prepared. Potatoes are actually good for you. They are low in fat, high in potassium and only have 150 calories per potato/serving. These are not empty calories either. There’s actual great vitamins and nutrients in those calories. So, nutrition and calorie-wise, potatoes are great to add to your diet.

Now if you’re doing a low carb diet, potatoes may not be the best option since a single potato has 36 grams of carbs and only 4 grams of fiber. This is why most people avoid them when they are on strict diets. The main reason potatoes can become unhealthy though is the way they’re prepared – especially when we’re talking mashed potatoes. It’s easy for the calories and fat to add up with all the butter, milk and cream generally in mashed potatoes. So don’t skip the spud, just make a few substitutes for healthy mashed potatoes.


How to make healthy mashed potatoes

I use Yukon Gold potatoes because they have a rich yellow color and buttery texture that makes them the perfect choice for healthy mashed potatoes (that uses less butter than traditional recipes).

I like starting with the potatoes cut into 2 inch chunks. This way when I boil the potatoes they cook more evenly and quickly, as compared to boiling them whole. I also throw in the garlic cloves with the potatoes in the pot. It helps to infuse that garlic taste into the mashed potatoes.

Once the potatoes are fork tender, I drain them and the garlic together and throw them in a mixer bowl when they’re still hot. You can mash them using a masher or fork. I like using my electric mixer because it’s hands-free and fast. Plus all that whipping makes the mashed potatoes extra fluffy.

After a couple minutes in the mixer, the mashed potatoes are ready to be served. You can leave them there for a shorter time if you like the mashed potatoes to be more chunky, or leave it in there longer and add more broth or more butter or more sour cream for an extra velvety rich result.

The end result is healthy mashed potatoes that are much lighter than traditional mashed potatoes, but taste just as good! Potatoes are truly the big hero side dish on Thanksgiving, but it doesn’t mean it has to be big on calories! I love the creamy, buttery texture and garlicky flavor of these mashed potatoes that just melts in your mouth. It pair so well with turkey, but also with chicken or steak recipes!

Tips for making the recipe

I’ve made some healthy swaps to make the classic mashed potatoes lighter in calories and fat. But I’ve got more tips for you to make more healthy swaps if you’d like so you can customize it to your diets and taste buds.

  1. Boil cauliflower with the potatoes and blend along with the potatoes. You’ll hardly notice the difference when blended together and you’ll consume less carbs that way.
  2. Use greek yogurt instead of low-fat sour cream. Both give a creamy, tangy taste to mashed potatoes. But sour cream is higher in fat and calories while Greek yogurt is higher in protein and has fewer calories
  3. Substitute the butter for olive oil. They both have the same fat content, but butter is a source of saturated fat, while olive oil is a source of monounsaturated fat (the good kinda fat)

Frequently asked questions

What is the best potato for mashing?

Starchier potatoes are the best for mashing, I used yukon gold, but russets would also work. Avoid waxy potatoes, like red or white, they require more mashing which can lead to a pasty texture.

How many calories are in mashed potatoes?

Mashed potatoes made with cream and milk, can have anything from 250 calories a serving and upwards. These creamy potatoes are around 180 calories per serving, so are a much lighter option.

What can I use to mash potatoes without a masher?

I use my stand mixer to mash my potatoes, it’s so easy and results in perfectly fluffy potatoes. A fork will do the job too, it’s just a little more work!

    1. Oh no! Is it possible that they got overmixed? Sometimes they will get gummy/slimy if they get overworked.

  1. I’m always grateful to find recipes that are healthy, delicious, and easy to prepare. These potatoes checked both boxes. I made a couple tweaks by substituting Greek yogurt for sour cream and chicken broth for vegetable broth.

  2. How much does this yield? I need 6 cups of mashed potatoes for another recipe and I’m not sure how many I would get with this recipe.

    1. When the recipe is set to 5 servings, it should make roughly 5 cups total, so it should be 1 cup per serving.

  3. I really enjoyed this low calorie mashed potatoes, creamy and fulfilling.
    Really good for me, who is on calorie deficit but always wanted to eat delicious food
