Effortless Mashed Potato Reheating: Mastering the Instant Pot Method!

The Ultimate Guide: How to Reheat Mashed Potatoes in Instant Pot


If you love mashed potatoes, chances are you’ve experienced the disappointment of reheating them only to find they’ve turned into a dry, lumpy mess. Luckily for us, technology has provided an incredible solution – the Instant Pot! In this post, we’ll walk you through the step-by-step process of reheating mashed potatoes using your trusty Instant Pot. Get ready for perfectly creamy and delicious mashed potatoes every time!

Gather Your Ingredients and Tools

Before diving into the reheating process, make sure you have everything you need:

Step 1: Prep Your Instant Pot

To begin, ensure that your Instant Pot is clean and ready to use. Place the trivet or steamer basket inside.

Step 2: Add Water to the Instant Pot

Pour one cup of water into your Instant Pot. This will create steam during cooking and help maintain moisture levels.

Step 3: Prepare Your Mashed Potatoes for Reheating

If your mashed potatoes have been refrigerated, remove them from the fridge and let them sit at room temperature for about 10 minutes before proceeding. This will allow them to warm up slightly.


  1. You can add a small amount of cooking oil or butter to enhance the flavor and texture of your mashed potatoes.
  2. If your mashed potatoes seem too dry, you can moisten them with a splash of milk or cream. Mix well before reheating.

Step 4: Place Mashed Potatoes in Instant Pot

Spoon the desired amount of mashed potatoes onto the trivet or inside the steamer basket inside your Instant Pot.

Step 5: Set Up Your Instant Pot

Close the lid securely and ensure that the pressure release valve is set to “Sealing.” Select manual/pressure cook mode on high pressure and adjust the cooking time using these guidelines:

  • For cold, refrigerated mashed potatoes: Set timer for 5 minutes
  • For room temperature mashed potatoes: Set timer for 4 minutes


The above timing suggestions are based on average portion sizes. Adjust accordingly if reheating larger quantities.

Step 6: Reheat Mashed Potatoes in Instant Pot

Once you’ve set up your preferred cooking time, press start to begin reheating. The Instant Pot will take some time to come to pressure before the actual cooking begins (approximately 10-15 minutes).

Step 7: Quick Release and Serve!

After the cooking cycle has completed, carefully perform a quick release by turning the pressure release valve from “Sealing” to “Venting.” Once all steam has been released and it’s safe, open your Instant Pot lid.


  1. To avoid condensation dripping onto your freshly heated mashed potatoes, use oven mitts/towels while releasing steam away from yourself and any surrounding objects.
  2. Check the consistency of your mashed potatoes. If they seem too dry, you can stir in a small amount of milk or cream to achieve your desired texture before serving.

The Result: Creamy and Delicious Mashed Potatoes!

Congratulations! You’ve successfully reheated your mashed potatoes using the Instant Pot method. Your patience has paid off, and now you can enjoy creamy and flavorful mashed potatoes that taste just as good as when freshly made.

Final Thoughts

The Instant Pot is truly a game-changer when it comes to reheating leftovers like mashed potatoes. Its ability to create steam during the cooking process helps retain moisture, resulting in perfectly heated spuds every time. So next time you find yourself with leftover mashed potatoes, give this method a try – we promise you won’t be disappointed! Happy cooking!
