3 Tips for Making Flavor Infused Mashed Potatoes

If you’re struggling to get the texture of your mashed potatoes down, then these helpful tips could be just what you need:

  • Use bigger pieces. Cut your potatoes into pieces that are at least 2 inches in size. Using smaller pieces than that can cause too much water to soak into the potatoes, which can end up taking away from their overall flavor.
  • Keep them hot. Mash your potatoes straight away after draining them while they’re hot – don’t wait for them to cool off. This will help to ensure that your potatoes turn out with a perfectly creamy texture.
  • Don’t infuse the potatoes all at once. You should be gradually adding in the additional ingredients (the garlic, sour cream, butter, and half and half in this particular recipe). By working the ingredients into the potatoes in smaller amounts, it will give the potatoes time to properly absorb the additional flavoring.

How to Store Mashed Potatoes for Later

Before storing any leftover mashed potatoes, you’ll first want to make sure that you allow the potatoes to cool completely. Transfer the cooled potatoes into an airtight container and seal them up tightly before storing in the fridge.

When properly stored like this, your mashed potatoes will keep for up to 3 to 5 days.

Alternatively, you can freeze leftover mashed potatoes by transferring them into a freezer-safe ziploc bag and storing in the freezer for up to one month.
