MASHED POTATOES RECIPE
Can you tell I’m getting excited for Thanksgiving? I’ve been sharing plenty of holiday side dishes and desserts, and I’m back today with another one!
Mashed potatoes are one of those side dishes that are fabulous year-round, with pot roasts, chicken, and so much more.
Fluffy, creamy, and oh so rich, these potatoes are simply the best! Definitely my go-to recipe.
Even though mashed potatoes are really easy to make, with this recipe there’s no standing around over the stove and waiting for a bit pot of water to boil.
Just add things to the Instant Pot, set it, and walk away!
No need to take up valuable stovetop space, especially on a busy holiday or even a weeknight.
HOW TO MAKE MASHED POTATOES IN THE INSTANT POT
- Add potatoes and liquid to pot. No need to spend a ton of time chopping the potatoes, just a quick quarter will do.
- Pressure cook. Pressure cook on high for 12 minutes, then release the pressure.
- Drain and mash. Drain the liquid, then add the potatoes back to the pot. Season, add sour cream, butter and cream. Mash.
- Serve. Serve hot, topped with a few pats of butter and sprinkle of fresh chives.
ADDITIONAL COOKING TIPS
Since mashed potatoes are such a classic dish, you want them to be perfect. Here’s a few helpful tips!
TYPES OF POTATOES TO USE
Technically it all comes down to personal preference, but my favorites are russets or yukon golds. Beyond them just being my favorite potatoes in general, they’re starchier, which make for very fluffy and smooth mashed potatoes. Waxier varieties, like red or white potatoes usually need more mashing to get as creamy, which can sometimes make the mashed potatoes gluey or pasty.
HOW MANY POTATOES TO USE PER PERSON FOR MASHED POTATOES
The rule of thumb is around 1/2 lb of potatoes per person. So this recipe uses 5 lbs of potatoes and serves 10 people. If you have huge potato lovers you’ll be serving, you might want to go with 3/4 lb per person.
DON’T SKIMP THE SALT
Season the potatoes well. A lot of people under-salt their mashed potatoes. This recipe is written per my family’s tastes, but use them as a guideline. If you’re sensitive to salt, start with 1/2 tsp of kosher salt, then take a quick taste. Add more salt, a pinch at a time, tasting in between until they’re just right. When in doubt, ask a family member to take a quick taste too.
WARM THE LIQUIDS
When adding liquids to cooked potatoes (like heavy cream), make sure they’re at least at room temperature, or warmed if you have the time. Adding cold liquids to hot potatoes can cool the potatoes down.
HOW TO MASH
There are three main ways to mash potatoes.
- Potato Masher – this is the most common way, and the cheapest. Potato mashers are generally less than $10. The downside is that it’s hard to get perfectly smooth potatoes by just mashing.
- Hand Mixer – it’s very easy to mash potatoes this way, and quick! The downside with this method is that it can be easy to overmix and potentially turn your potatoes into a gluey paste (especially if you used a waxier potato variety, like red or white potatoes).
- Potato Ricer – the most time consuming method, but hands down the most fool-proof way to have perfectly velvety smooth potatoes. I usually use this method for Thanksgiving, but for a simple weeknight meal, I use my hand mixer.
VARIATIONS OF THIS RECIPE
- CREAM CHEESE – use up to 6 oz of softened cream cheese (cubed) for a subtle tang and extra creaminess.
- GARLIC – peel and smash (use the back of your knife to smash the cloves) 5 garlic cloves, and add them to the Instant Pot with the potatoes before pressure cooking.
- CHEESY – stir in a handful of your favorite cheeses!
- LOADED – stirring in some sour cream, cheddar cheese, bacon pieces and extra chives or green onions gives these potatoes a loaded baked potato flavor.
- BROWNED BUTTER – halfway through the potatoes cooking, add 1/2 cup butter to a sauce pan and brown. For an in depth description of how to brown butter, look for the section of this post titled “Tips for Browning Butter”. Stir in about 2/3 of the butter when mashing, and reserve the rest for drizzling over the top of the mashed potatoes.
MAKING MASHED POTATOES AHEAD OF TIME
You can make the mashed potatoes then cool them completely and refrigerate in an airtight container. This can be done 1-2 days ahead of time. The day you want to serve them, you have a couple of options to reheat them:
- Instant Pot – add mashed potatoes to Instant Pot insert, secure the lid and press “keep warm”. Stir occasionally and warm until potatoes are heated through. Top with a few pats of butter, stir and serve.
- Crockpot – add mashed potatoes to slow cooker, cover and cook on LOW for 3 hours, stirring a few times. Right before serving, dollop with a little bit of butter and stir.
- Oven – add mashed potatoes to pan, and bake at 375 for 30-45 minutes, stirring once or twice. Add additional butter or cream if needed before serving.
You can also make these potatoes up to 3 hours before serving, secure the lid, and keep them on the “keep warm” setting. Side dish, done!
Leftover mashed potatoes should be refrigerated in an airtight container and consumed within 3-5 days.
