Fluffy mashed potatoes made with russet potatoes are a classic potato dish that is perfect for a meal prepped lunch or Thanksgiving dinner. The choice of russet potatoes plays an important role in achieving the desired fluffiness. Russets have a high starch content and low moisture, making them ideal for creating light and fluffy mashed potatoes.

Using a ricer is essential to transforming the russet potatoes into a uniform smooth and airy consistency if that is the style that you are seeking. A potato masher will work fine as well but will not give the uniform consistency that a potato ricer would. If all you have is a potato masher, be sure to mash all the chunks to get it as smooth as possible.
To maintain the fluffiness, it’s crucial to be gentle when combining the softened butter, warmed milk, salt, black pepper, and optional garlic powder with the mashed potatoes. Over-mixing can cause the potatoes to become dense, gummy, and lose their lightness. Using warmed milk and softened butter makes it easier to incorporate into the potatoes and reduces the risk of over-mixing the mashed potatoes.
With this fluffy mashed potato recipe, you have a classic side dish perfect for a wide range of occasions. Whether you’re hosting a festive holiday feast or a cozy family dinner, these fluffy mashed potatoes are the perfect accompaniment.
