Key Ingredients & Substitutions
Potatoes: Russet or Yukon gold potatoes work great for this recipe. Russets give a fluffy texture, while Yukon golds add a creamier feel. If you’re in a pinch, red potatoes can also be used, but they’re a bit waxy and won’t mash as smoothly.
Butter: Unsalted butter is best so you can control the saltiness. You can swap it for olive oil or vegan butter for a dairy-free option if needed. I like to add an extra pat of butter on top when serving—such a nice finishing touch!
Milk/Cream: Whole milk makes for a rich flavor, but you can use 2% milk or even almond milk for a lighter option. Heavy cream makes it extra decadent. You can also use sour cream or cream cheese for an added tang and creaminess.
Herbs: Fresh thyme or parsley add flavor and color. If you don’t have fresh herbs, you can use dried herbs. Just remember that dried herbs are more potent, so use a smaller amount.
How Do I Get Really Creamy Mashed Potatoes?
The key to creamy mashed potatoes is all in the mixing and the ratio of liquid to potatoes. Follow these steps to avoid lumps:
- Choose high-starch potatoes like Russets, as they break down easily.
- After mashing, add warm milk or cream gradually. This keeps the potatoes fluffy instead of gummy.
- For the smoothest texture, you can use a hand mixer, but don’t overbeat, as it can lead to a gluey consistency.
- Adjust the milk and butter based on your desired creaminess—feel free to taste and adjust as you mix!
With these tips, your Instant Pot mashed potatoes will turn out perfectly every time!

Instant Pot Mashed Potatoes
Ingredients You’ll Need:
- 3 pounds russet or Yukon gold potatoes, peeled and quartered
- 1 cup water
- 4 tablespoons unsalted butter, plus extra for serving
- 1/2 cup whole milk or heavy cream, warmed
- Salt, to taste
- Freshly ground black pepper, to taste
- Fresh thyme or parsley leaves, for garnish (optional)
How Much Time Will You Need?
This recipe takes about 15 minutes of prep and 8 minutes of cooking time in the Instant Pot. You will also need a few minutes for releasing the pressure and mixing the ingredients together. Total time is around 30 minutes, making this a quick and easy side dish!
Step-by-Step Instructions:
1. Prepare the Potatoes:
Start by peeling and quartering the potatoes. Make sure they are roughly the same size for even cooking. Place the peeled and quartered potatoes into the inner pot of the Instant Pot.
2. Add Water:
Pour 1 cup of water over the potatoes. This will create steam to cook them perfectly.
3. Set Up the Instant Pot:
Secure the lid on the Instant Pot and ensure the valve is set to the sealing position. This is important to trap the steam inside during cooking.
4. Cook the Potatoes:
Select the Manual or Pressure Cook setting and set the timer for 8 minutes on high pressure. Once the cooking time is up, be patient while the Instant Pot does its thing!
5. Release the Pressure:
When the cooking is complete, carefully perform a quick pressure release by moving the valve to the venting position. This will release the steam. Make sure to keep your hands and face away from the steam outlet.
6. Drain and Mash:
Open the lid cautiously, and drain any remaining water from the pot. Using a potato masher or a hand mixer, mash the potatoes right in the Instant Pot until they reach your desired smoothness.
7. Add Butter and Milk:
Add the butter and warmed milk or cream to the potatoes. Mix well until everything is combined and the potatoes are creamy. Feel free to adjust the amount of milk or butter based on how creamy you like them!
8. Season and Serve:
Season the mashed potatoes with salt and freshly ground black pepper to taste. Transfer them to a serving bowl, and if desired, top with a couple of pats of butter and sprinkle with fresh thyme or parsley for a lovely touch.
9. Enjoy!
Serve the mashed potatoes immediately and enjoy the comforting, fluffy goodness!
Can I Use Different Types of Potatoes?
Yes! While russet and Yukon gold potatoes are recommended for their creamy texture, you can also use red potatoes. However, they tend to be waxier and may not mash as smoothly.
Can I Make These Mashed Potatoes Ahead of Time?
Absolutely! You can prepare the mashed potatoes and keep them warm in the Instant Pot on the ‘keep warm’ setting for up to an hour. If making further ahead, store them in the fridge and reheat gently on the stove, adding a splash of milk to restore creaminess.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, add a little water, milk, or cream, and warm them on the stove or in the microwave, stirring occasionally to ensure even heating.
Can I Add Flavor Variations?
Definitely! You can add roasted garlic, cheese, or sour cream for extra flavor. Fresh herbs like chives or rosemary also work well, so feel free to get creative!
