These high‑protein cottage cheese mashed potatoes are ultra‑creamy, full of flavour, and satisfyingly smooth. They make an excellent side for holiday dinners, family meals, or busy weeknights when you want comfort food that’s a little lighter but still indulgent.

Simple to prepare, this recipe combines fluffy boiled potatoes with butter, milk, garlic and cottage cheese. The cottage cheese gives the mash a velvety texture and a protein boost while contributing a tang similar to sour cream but with fewer calories. For the creamiest result, you can briefly blend the cottage cheese before folding it into the potatoes, though it’s optional if you prefer a bit more texture.

Ingredients you’ll need:
This recipe uses a short, straightforward ingredient list—easy to scale and flexible depending on what you have on hand.
- Potatoes: Choose floury or all‑rounder varieties for a light, fluffy mash. Good options include Sebago or washed white potatoes in Australia, or Russet and Yukon Gold in the US.
- Cottage cheese: Adds creaminess, flavour and protein. Blend it first if you want a perfectly smooth texture.
- Milk: Any milk works—dairy or plant‑based. Use what you have; whole milk or cream will produce a richer mash.
- Butter: Unsalted butter gives a rich mouthfeel; adjust salt after combining ingredients.
- Garlic: Fresh minced garlic brightens the flavour—roasted garlic is a delicious alternative for a deeper, sweeter garlic taste.
- Salt and pepper: Freshly ground pepper and salt to taste.
- Garnish: Chopped chives or parsley and an extra pat of butter to finish.

How to make cottage cheese mashed potatoes
Prepare the potatoes: Peel if you like and cut potatoes into evenly sized pieces so they cook uniformly.


Boil: Place potatoes in a large pot, cover with cold water and add about 2 teaspoons of salt. Bring to a boil over high heat.
Cook: Reduce to medium and simmer until fork‑tender, about 15–20 minutes depending on the size of the pieces.
Optional step: If you want an ultra‑silky mash, pulse the cottage cheese in a blender or food processor until smooth.
Drain: Drain the potatoes well and return them to the warm pot to remove excess moisture.
Mash: Add butter, cottage cheese, milk, minced garlic, salt and pepper. Use an electric mixer on high for a very smooth texture, or mash by hand if you prefer a chunkier finish. Adjust milk to reach your desired consistency.

Garnish and serve: Top with an extra pat of butter and a sprinkle of chopped chives or parsley. Serve hot for the best texture and flavour.
Substitutions and additions
- Milk options: Swap in almond, soy or oat milk if you prefer a dairy‑free version. For greater richness, use cream or half‑and‑half.
- Roasted garlic: Roast a head of garlic and mash the soft cloves into the potatoes for a mellow, caramelized garlic flavour.
- Different potatoes: Try sweet potatoes or a mix of white and sweet potatoes for a unique twist.
- Extra flavour: Stir in grated Parmesan, sour cream, or a spoonful of Dijon mustard for an added depth of flavour.
- Toppings: Finish with extra butter, a drizzle of olive oil, chopped herbs, or crispy fried onions for texture.

Tips & tricks
- Avoid over‑mashing: Stop once the potatoes are smooth with no large lumps—overworking starchy potatoes can make them gluey.
- Adjust consistency: Add milk gradually and stop when the texture is just right for you.
- Season as you go: Taste and adjust salt and pepper after combining the cottage cheese and milk so you don’t under‑ or over‑season.
How to store
These mashed potatoes are best served fresh but keep well for a short time.
To store: Allow to cool slightly, transfer to an airtight container and refrigerate for up to 3 days.
To reheat: Warm gently in the microwave or on the stovetop, stirring in a little extra butter or milk to refresh the texture.
Recipe FAQ
Floury or all‑rounder potatoes work best for a light, fluffy mash. Examples include Sebago, Russet and Yukon Gold.
A good guideline is about two medium potatoes per person; increase slightly for heartier appetites.
No—blending the cottage cheese is optional. Blending yields a smoother texture, but leaving it as is adds a pleasant curdy bite.
