There are few things better than perfect, creamy, homemade mashed potatoes.

There are a ton of different ways to make mashed potatoes. From the type of potato you use, whether or not you cut them before boiling, how long you boil them, and even how you mash them!

In my recipe, we’ll be using Russet potatoes as those have an ideal consistency for mashing, they’re budget-friendly, easy to find, and perhaps already in your house.

Let’s go over everything else you need to know to make the smoothest, creamiest potatoes every time!

How to Make the Best Homemade Mashed Potatoes

⭐Use a Starchy Potato:

  • Russets or Yukon Golds are perfect for mashing. You can also use a combination of both!
  • Using waxy potatoes such as red or new potatoes can cause your mashed potatoes to have a gluey consistency as opposed to being nice and creamy.

⭐Cut the potatoes into smaller pieces of equal size

  • This allows them to cook evenly. Some say to boil the potatoes whole to prevent them from absorbing too much water, but they cook unevenly this way.
  • You can choose to leave the skins on or off, or you can leave some of them on.

⭐Use COLD Water:

  • Add the potatoes to cold and salted water before boiling.
  • Using hot/warm water will cause the outside of the potato to heat up before the middle does, which will cause uneven cooking.

⭐Salt the water once it’s reached a boil:

  • This is the best way to evenly season the potatoes, you can always add more salt at the end.

⭐Let the Steam Rise after Boiling:

  • Once you’ve drained the potatoes, return them to the warm pot and let them steam for 5 minutes, this will allow excess moisture that they absorbed to steam away.

⭐Don’t Add Cold Ingredients to Warm Potatoes:

  • Make sure your butter is completely softened or even melted.
  • Make sure that your milk/half and half is warmed up slightly before being added.
  • The potatoes will absorb them better this way and they will end up much creamier.

⭐Add Butter Before the Half and Half/Sour Cream:

  • The butter helps to coat the starch and gives you a silkier consistency.

⭐Don’t Over-Mash:

  • Potatoes release starch every time they’re handled/mashed. Too much starch leads to a gluey, gummy consistency.
  • A potato masher with small holes works well for this. Avoid any type of electric mixer as they will go from creamy to gluey very quickly.

Make Ahead Method

  • Add an extra  1-2 Tablespoons butter.
  • Stir in 2-3 additional Tablespoons warmed half and half, (preferably whole), at the end of cooking. Cover the pot with foil or transfer to a casserole dish.
  • Refrigerate for 1-2 days.
  • Let it sit out for 1 hour prior to reheating.

Reheating Cold Mashed Potatoes

Stirring occasionally is ideal of all methods below. Add a little warm half and half if the potatoes appear too thick.

  • Oven: Cover and cook at 350° for 30 minutes.
  • Stove: Medium-low heat for about 20 minutes, covered.
  • Slow Cooker: Low heat for 1-2 hours. Reduce to warm until ready to serve.
  • Microwave: 50% power in 1-minute intervals, covered, until heated through. Stir in between.

Freezing Leftovers

If you plan on freezing leftovers, be extra generous with the half and half and butter. Per The Kitchn, this helps them freeze and reheat well.

Freezing the remaining batch:

  • Place all of your cooled leftover potatoes into a freezer bag, remove air, seal tightly, and freeze.

Freezing Portion Sizes:

  • Line a baking sheet with parchment paper.
  • Use a measuring cup to scoop 1-cup portion sizes onto the sheet.
  • Flash freeze for 1 hour.
  • Transfer to a freezer Ziploc bag. Best if used within 3 months.

Reheating Frozen Potatoes:

Let the potatoes thaw in the fridge overnight or defrost in the microwave. Then refer to reheating instructions above.
