What potatoes should I use for mashed potatoes?

When it comes to making mashed potatoes, it’s important to use the right type of potato.

Yukon Gold potatoes are another great option for mashed potatoes due to their buttery flavor and creamy texture. Red potatoes, though lower in starch, are also good for mashed potatoes because of their earthy flavor. Regardless of the type of potato you choose just make sure that it is well-cooked before mashing

Making sure your potatoes are cooked enough is essential to getting a smooth texture.  If you think they are done but have struggled with the right texture in the past, let them cook 2-3 more minutes before you drain them.

There are a variety of butter substitutes for mashed potatoes that will still provide the flavor and texture you’d expect from butter. Whether you’re looking to cut down on saturated fat or just want to try something new in your cooking, these butter alternatives are sure to please.

If you are able to have dairy products, there are many alternatives you can use that you likely have on hand.

If you can’t tolerate dairy or are allergic to it (or simply don’t have any) there are many vegan alternatives.

From coconut milk and vegan butter to stock and applesauce, each replacement has its own unique benefits which make it perfect for adding richness and creaminess without all the unhealthy fats found in butter.
