There's something about mashed potatoes that makes any meal feel more complete, a classic comfort food made by mashing cooked potatoes with butter and milk.
They're comforting, rich, and always welcome at the table-whether you're serving roast chicken or just want something cozy on a weeknight.
This Instant Pot version makes the whole process smoother, pressure-cooking the potatoes on high for about 10 minutes and eliminating prolonged boiling.
You skip the boiling, save the stovetop space, and still end up with soft, creamy, garlicky mashed potatoes that taste like you hovered over them for an hour.
Whether you serve them at Thanksgiving or alongside a Tuesday night meatloaf, these mashed potatoes always deliver.
Why You’ll Want to Make These Again and Again
Mashed potatoes are the kind of side dish everyone loves-but they can be a hassle if you're boiling, draining, and trying not to overmix.
The Instant Pot takes all that and turns it into a simple, reliable process.
- One pot, no draining - Cook and mash in the same pot with no extra mess, cutting cleanup down to a single pot.
- Perfect texture every time - The pressure cooking gets them soft and fluffy when cooked on high pressure for 10 minutes.
- Garlic infuses right in - No need to roast or sauté it separately.
- Easy to customize - Add more butter, stir in cheese, or go dairy-free if needed.
- Works for meal prep or holidays - Reheats like a dream, keeps warm on low, and doubles easily, and pairs well with other make-ahead dishes like make-ahead cookout recipes for stress-free BBQs.
This is a recipe you can keep in your back pocket-because mashed potatoes go with just about everything.
What You’ll Need to Make It
The ingredient list is short, but every piece plays a part. Use good potatoes, real butter, and fresh garlic for the best results.
- Yukon Gold Potatoes - Creamy and rich, they mash beautifully without needing a ton of butter or cream, a Canadian-developed variety prized for its naturally buttery flavor.
- Garlic Cloves - Peeled and added whole to cook with the potatoes. They soften and mellow out perfectly during the Instant Pot's 10-minute high-pressure cook.
- Butter - Salted or unsalted, stirred in at the end for richness.
- Milk or Cream - Use heavy cream for a richer finish, or milk for something lighter.
- Salt and Pepper - Always season your potatoes well!
- Optional Add-ins: Sour cream, cream cheese, chives, grated Parmesan, or roasted garlic for more depth.
The base recipe is simple-so it's easy to riff on depending on what's in your fridge, and they pair nicely with deviled eggs for brunch sides.
For a spicy, spreadable mix-in try nduja sausage for spicy, spreadable heat to add smoky depth.
How to Make Garlic Mashed Potatoes in the Instant Pot
This method keeps everything in one pot, and it's ready start-to-finish in about 25 minutes.
- Prep the potatoes - Peel (or leave the skins on for rustic texture) and cut into 1½ to 2-inch chunks. Add them to the Instant Pot with whole garlic cloves and just enough water to cover.
- Pressure cook - Seal the lid and cook on high pressure for 10 minutes. When finished, do a quick release.
- Drain if needed - If the water isn't fully absorbed, pour out the excess or use a slotted spoon to transfer the potatoes to a bowl.
- Mash and mix - Add warm milk or cream and softened butter right into the pot. Mash until smooth or fluffy, depending on how you like them.
- Season and serve - Add salt and pepper to taste. Stir in extras like sour cream, roasted garlic, or chives if using.
And that's it. Creamy, garlicky, classic mashed potatoes-made simpler.
Topping Ideas and Add-Ins
Once you've got the base down, there are so many ways to change up the flavor, from bright herbs to smoky spices, such as chives for brightness or smoked paprika for smoky warmth.
Here are some of our favorite ways to take them up a notch.
| Add-On or Topping | What It Does |
|---|---|
| Roasted Garlic | Extra depth and sweetness from slow-roasted cloves |
| Sour Cream or Cream Cheese | Adds tang and even more creaminess |
| Fresh Chives or Green Onion | Brightens and balances the richness |
| Grated Parmesan or Asiago | Brings a salty, nutty finish |
| Crumbled Bacon | Crunchy, smoky, and makes it a full-on main if you want |
| Olive Oil or Butter Drizzle | Adds richness and a glossy finish |
| Smoked Paprika or Chili Flakes | For a subtle kick and warm color |
They'll be great either way and pair well with leftover rotisserie chicken dinner ideas.
If the meal is small, finish with small-batch cupcakes for intimate dinners that complement a cozy dinner.
How to Store and Reheat Garlic Mashed Potatoes
Mashed potatoes store well, but they do thicken in the fridge.
The trick is adding a little liquid when reheating to bring them back to life.
Storage Tips
- Let them cool completely before transferring.
- Store in an airtight container in the fridge for up to 4 days.
- You can freeze mashed potatoes, but expect the texture to change slightly. For best results, use within 1 month.
Reheating Tips
- Microwave: Add a splash of milk or broth, stir, and heat in 30-second bursts until warmed through.
- Stovetop: Reheat over low heat with a bit of liquid, stirring regularly to avoid sticking.
- Oven: For big batches, cover with foil and warm at 325°F for 15-20 minutes.
They're still fluffy, smooth, and delicious-even the next day.
Garlic Mashed Potatoes FAQ
Can I leave the skins on?
Absolutely. Yukon Golds have thin skins and make for a more rustic mash.
Just scrub well first.
Can I use russet potatoes?
Yes, but they're more starchy and will need more butter or cream to keep them smooth.
Can I make this dairy-free?
You can! Use olive oil or a plant-based butter, and swap the milk or cream for a dairy-free version.
How do I keep mashed potatoes warm?
Use the "Keep Warm" setting on your Instant Pot or keep them in a covered dish over a pan of simmering water.
What’s the best way to mash them?
Use a potato masher for a chunky texture or a hand mixer for a smoother finish. Avoid a food processor-it can make them gluey by overworking the potato starches and releasing excess starch, which creates a gummy texture.
