Whipped Cottage Cheese Mashed Potatoes - a higher protein side dish

If you’ve been looking for a new way to enjoy mashed potatoes without all the heavy cream and loads of butter, these cottage cheese mashed potatoes are just what you need!

Creamy, satisfying, and packed with more protein than "normal" mashed potatoes, this recipe puts a healthy spin on a classic dish. You get the comfort of traditional mashed potatoes with the added bonus of creamy whipped cottage cheese—no one will guess they're lightened up!

These mashed potatoes with cottage cheese are so easy to make, and they pair perfectly with any main dish. Plus, they make a nourishing, higher-protein side that fits right into a balanced eating plan. Once you try them, you may never make mashed potatoes the same way again!

What are cottage cheese mashed potatoes?

Cottage cheese mashed potatoes are your favorite creamy comfort food made even better. By swapping out heavy cream and loading in blended cottage cheese, you get the same rich, smooth flavor with a major boost of nutrition (and protein).

These are not just any mashed potatoes—they have a tangy twist and a creamy texture you’ll absolutely love. No one will know they’re healthier!

Why add cottage cheese to mashed potatoes?

Let’s be honest—cottage cheese in mashed potatoes might sound unusual, but it works beautifully. It adds richness and body without all the fat, and it bumps up the protein content big time.

One cup of low-fat cottage cheese has nearly 24 grams of protein, making this a higher protein option that keeps you full and satisfied. And when you whip it smooth, you won’t even know it’s there. You just get ultra creamy mashed potatoes with a subtle, tangy flavor.

Trust me, once you try this trick, you'll be using cottage cheese to make all your favorite dishes better.

How to make cottage cheese mashed potatoes

Making this recipe is super simple and takes only about 30 minutes from start to finish.

Start by peeling and cubing your favorite potatoes—either russet potatoes or Yukon Gold potatoes work great. Add the potatoes to a large pot, cover with water, and stir in a bit of salt. Bring to a boil over high heat, then reduce to medium and cook the potatoes until the potatoes are fork tender—about 15–20 minutes.

Once the potatoes are cooked, drain them well and return the potatoes to the pot.

Now for the secret ingredient: add the cottage cheese along with butter, a sprinkle of garlic powder if you’d like, and a little more salt and pepper to taste.

Here’s where the magic happens...

Want the creamiest mashed potatoes ever?

Use an immersion blender right in the pot to blend everything together until smooth and fluffy. This extra step transforms your dish into luxurious, velvety mashed potatoes without adding cream.

If you don’t have an immersion blender, you can also use a potato masher or hand mixer or toss the ingredients into a food processor. 

If the mixture is too thick, just stir in a splash of milk until you reach the perfect consistency.

Best potatoes for mashed potatoes with cottage cheese

For the smoothest, fluffiest texture, I recommend using Yukon Gold potatoes or russet potatoes. These starchy varieties are the best potatoes for mashed potatoes, breaking down easily and absorbing flavor beautifully.

If you prefer a slightly chunkier texture, you can use yellow potatoes or mix in a waxier variety. This recipe works great with whatever potatoes work for you!

Do I need to peel my potatoes?

That’s totally up to you! If you like extra creamy mashed potatoes (like me), you might want to peel your potatoes first. But if you're using thin-skinned Yukon Golds, you can leave the peels on for a bit of texture and added nutrients.

Whipped cottage cheese for the best texture

One of the keys to getting smooth, creamy mashed potatoes with cottage cheese is making sure your cottage cheese mixture is completely smooth.

My first recommendation is using a handheld immersion blender. But if you don't have that, you can blend your cottage cheese in a food processor to make sure it is smooth BEFORE you add it to the potatoes.

To do that, blend the cottage cheese in a food processor or blender until silky before mixing it into your mash. You’ll never have to worry about curds showing up in your potatoes.

Want a shortcut? Try whipping your cottage cheese ahead of time and keeping it in the fridge—ready to stir in when you’re making dinner.

How to make this a high protein side dish

This is where this recipe really shines. Most traditional mashed potatoes are carb-heavy and lack protein—but not this one!

Thanks to the cottage cheese, each serving contains about 8 grams of protein, making it a filling and balanced side dish. You don’t need heavy cream to get that velvety finish. Just good, clean ingredients and a smart technique.

And if you’re looking to really power-pack it, stir in some sour cream or plain Greek yogurt for added protein and flavor.

Flavor Ideas to take this mashed potato recipe to the next level

There are so many ways to make these cottage cheese mashed potatoes your own!

• Add roasted garlic for garlic mashed flavor
• Sprinkle in chopped chives, rosemary, or parsley
• Mix in shredded cheddar for cheesy goodness
• Kick it up with paprika or cayenne for a spicy version

No matter how you flavor them, the creamy base and light tang from the cottage cheese make a delicious backdrop for any variation. You’re going to love this recipe and want to make it again and again!

What to do with leftover creamy mashed potatoes

Have leftovers? Lucky you!

Leftover mashed potatoes can be stored in an airtight container in the fridge for 3–4 days. Just be sure they have cooled before sealing.

When you’re ready to reheat, just add a splash of milk and warm gently on the stove or microwave. You can also repurpose them into potato patties, add them to soups, or use them in shepherd’s pie.

Why these mashed potatoes are so creamy

The combo of fluffy mashed potatoes combined with smooth whipped cottage cheese is what brings these mashed potatoes to the next level. No lumps, no grainy texture—just a rich, silky mash you’ll want to serve with everything.

They’re just as good for holidays as they are for weeknight dinners. This is one of those potato recipes that feels special, but is simple enough to make anytime.
