🔪 How To Make Instant Pot Mashed Potatoes

This recipe is the easiest way to make some delicious mashed potatoes! All you will need is your Instant Pot or pressure cooker something to mash with (like a potato masher, ricer, or even a fork).

This recipe makes 10 servings, so you will have enough for the whole family!

Prep the Potatoes

1. Prepare your Instant Pot. Add 1 cup of water to your Instant Pot until it is about 1 inch deep. (This should take no more than 1½ cups of liquid - *see note). Next, salt the water with 1 teaspoon of salt.
2. Add potatoes. Add 5 pounds of russet potatoes that have been peeled and chopped into cubes.

Add To Instant Pot & Cook

1. Cook. Set the valve to ‘sealing’, then press the ‘manual’ button and set your Instant Pot or pressure cooker to 12 minutes.
2. Vent. When the cooking time is up, do a manual release by switching the valve to the ‘venting’ position. (If splattering happens, turn the valve back to ‘sealing’ then wait a moment and try again).

Combine & Serve

1. Add ingredients and mash potatoes. When the Instant Pot has finished ‘venting’. Carefully open the lid and add ½ cup of milk, ¼ cup of butter, and salt and pepper to taste. Use a potato masher or ricer to mash the potatoes to your desired consistency.
2. Serve. Transfer to a serving dish and serve immediately.

💭 Tips & Notes

• You are aiming for 1" of water or broth on the bottom of your Instant Pot. How much liquid that takes will depend on the model of your pressure cooker. So, start with 1 cup of liquid, but don't use more than 1½ cups total.
• If using broth instead of water, adjust (reduce) the salt accordingly.
• You could also use Yukon Gold potatoes in this recipe. Their skin is more tender which makes them ideal for skipping the peeling process if desired.
• For garlic mashed potatoes, add a few garlic cloves to the potatoes before cooking. After cooking, just mash everything together!

🥡 Storing & Reheating

Place leftover Instant Pot mashed potatoes in an airtight container and enjoy within 3 days. Once cooled, leftover potatoes can be frozen in a heavy duty freezer bag or airtight container for up to 3 months.

Thaw in the fridge before reheating.

Reheating Instant Pot Mashed Potatoes

Put the leftover mashed potatoes in a baking dish with a few extra tablespoons of butter or milk and cover with foil. Bake at 350°F (175°C) until warmed through, usually 20-25 minutes.

I like to give it a stir at the halfway point and add more liquid if needed. Once hot, stir and serve. Alternatively, individual portions can be popped in the microwave.

❓ Can I Make Mashed Potatoes Without A Potato Masher?

Yes! A potato masher or potato ricer is an easy way to mash potatoes, but you can make them without it. In particular, a fork or whisk works just as well!

❓ Can I Make Instant Pot Mashed Potatoes Without Milk?

Yes, there are many different options for what you can use instead of milk for Instant Pot mashed potatoes. A good alternative that still uses dairy is heavy cream or half and half. For some non-dairy options, you can try a milk substitute such as almond milk or cashew milk or you can use chicken broth!

❓ Can I Cook My Instant Pot Mashed Potatoes In Milk?

Yes, your potatoes can be cooked in milk in your Instant Pot! In fact, this yields some extra creamy mashed potatoes! Instead of adding water or broth as your cooking liquid, use a half-and-half mixture of broth and milk!

❓ How Do You Scald Milk Quickly For Mashed Potatoes?

Use a heavy-bottomed skillet for the best, quick results. *A wide, shallow saucepan will work too but the wider the cooking surface, the faster your milk will heat.

Add your portion of milk and heat over medium. Stir frequently until bubbles begin forming around the edges of the skillet and your milk reaches a temperature of 180-185°F (82-85°C).
