Butter is a usual suspect in mashed potatoes, because it provides a lovely, creamy texture. But then, that nice creaminess has its downsides. Butter is not vegan and may not meet your dietary needs.

So the question comes up: What should I substitute for butter in mashed potatoes?

Below I’ll share the rundown on 10 ingredients you can use as an alternative to butter in your mashed potatoes.

Extra virgin olive oil can impart a rich and fruity flavor to mashed potatoes. Use a good-quality oil for the best results. Start with a small amount and adjust to taste.

2. Greek yogurt or sour cream

Thicker dairy products like yogurt and sour cream provide creaminess plus a tangy flavor. Lower fat options can be healthier than butter.

3. Cream cheese

Cream cheese has less fat and calories than butter, but is nearly as indulgent. Use a small amount to start and adjust to taste.

4. Broth

You can use chicken broth or vegetable broth in your mashed potatoes. You’ll miss out on butter’s creamy quality, but the slightly salty flavor is a nice addition. Start small and add as you are mashing to reach the consistency you want.

5. Almond milk

Unsweetened, unflavored almond milk is another substitute for butter in your mashed potatoes. As with the broth, add a little at a time as you are mashing.

6. Buttermilk

Some chefs prefer buttermilk over butter in mashed potatoes. Give it a try and you’ll see — buttermilk adds some tang and a velvety feel.

7. Milk

When in doubt, milk or cream stands in nicely for butter. See substitute for milk in mashed potatoes for more information. You can also use milk plus a bit of olive oil to balance fat content with flavor and texture.

8. Herb-infused oil

For a different take on mashed potatoes, try using olive oil infused with rosemary, thyme, or garlic. To avoid overwhelming your potatoes with flavor, start with a small amount and add to taste.

9. Avocado

Avocado makes a lovely butter substitute. It has that creamy texture plus a mild flavor and loads of nutrients. The only drawback is the color. If you don’t mind green mashed potatoes, this alternative ingredient is worth a try.

10. Pureed cauliflower

Steamed and pureed cauliflower mixed into mashed potatoes will add a creamy texture and spares you the fat and calories of butter.

Why people love butter in mashed potatoes

Butter is made by churning the cream of cow’s milk. It is almost entirely saturated fat, which may cause some health concerns. Key aspects of butter’s nutritional profile per 100 grams are:

  • 717 calories
  • 81 grams of fat
  • 51 grams of saturated fat
  • 215 mg of cholesterol

The thing is, all that fat tastes good when mixed with low-fat ingredients like potatoes. So most people looking for a butter alternative want a substitute that mimics the fattiness. With that in mind, the best substitutes are usually olive oil, cream cheese, and whole milk yogurt. Avocado is another great choice, but the color may be off-putting.
