Notes

Recipe FAQs

What kind of potatoes work best for Instant Pot mashed potatoes?
Yukon Gold or Russet potatoes are ideal. Yukon Golds are naturally creamy and buttery, while Russets create a fluffier texture. You can also mix the two for a balance of creamy and fluffy.
 
Can I double the recipe in the Instant Pot?
Yes, but make sure you don’t fill the Instant Pot past the maximum fill line (usually ⅔ full). You may also need to increase the cooking time by 1-2 minutes depending on the quantity.
 
Can I freeze leftover mashed potatoes?
Yes, you can freeze mashed potatoes. Store them in an airtight container or freezer bag for up to 2 months. When reheating, add a little milk or butter to restore creaminess.
