Why Are These Cheesy Mashed Potatoes Are Our Favorite Side Dish?

So much flavor! These mashed potatoes are unbelievably creamy and flavorful. I eat these as a side dish or even topped with chicken nuggets, corn and some gravy for a mashed potato bowl!
Two kinds of cheese! You use cream cheese in the potatoes along with grated cheddar cheese, plus more cheddar on top so they’re extra cheesy!
Easy to make ahead! The great thing about these mashed potatoes are they are versatile. You can make them and enjoy immediately, but you can also make them ahead and pop them in the oven when you’re ready to serve, which is a fantastic option for holidays or entertaining.

What Kind Of Potatoes Are Best For Mashed Potatoes?

Russet Potatoes. I typically use russet because they always produce perfect results! They are more starchy and give you the creamiest mashed potatoes. Russet potatoes soak up the butter and milk nicely making the silkiest texture, and the smoothest mashed potatoes ever.
The next best option are Yukon Gold. They’re slightly more waxy (but not as waxy as Red) and will give you a nice flavor. You might have a few more lumps with gold potatoes, so when I use these, I always run them through my ricer.
Avoid Red Bliss potatoes when making creamy mashed potatoes, as they are the most waxy, leave the most lumps, and don’t absorb your add-ins as nicely. However, if you prefer more of a “country-style” or rustic mashed potato that has more lumps, with the skin left on, mashed only by hand, red will work.

What Kinds of Cheese Do You Use?

For this cheesy mashed potato recipe I use a combination of cream cheese and mild or sharp cheddar cheese. I find these cheeses melt beautifully and give the potatoes a mild cheesy flavor. If you’re looking for a cheese that will add more flavor try these:

Asiago
Gouda
Gruyere
Provolone
Taleggio
Parmesan Cheese

OR you can combine a few different cheeses to come up with your own blend. But I don’t recommend skipping the cream cheese, as that adds richness and creaminess without adding a ton of flavor.

How To Make the Best Mashed Potatoes

Peel your potatoes and cut them up into chunks. I usually quarter the potatoes depending on the size, Just make sure the chunks are the same size so they boil evenly! Once they’re fork tender drain them really well!

Place all your potatoes into a bowl and mash them up! You can use an electric hand mixer, a stand mixer, a potato masher, or even use a potato ricer. Once they’re all mashed stir in your butter, cream cheese, sour cream, seasonings, egg, and some of the cheddar cheese. The warmth of the potatoes will melt the cheeses.

Now you can stop there and enjoy immediately, OR you can spread the potatoes into a greased casserole dish and top with more cheddar cheese and bake! Baking the potatoes gets them super warm and melty, melts that extra cheese on top, and brings it all together! Plus, this method is great for making them ahead! Sprinkle them with bacon, chives, green onions, or parsley for flavor and presentation!

TIPS

I have a few tips to share to ensure perfect results every time!

I have transitioned into using a potato ricer every time I make mashed potatoes. I feel like it produces the silkiest and creamiest results, but it absolutely isn’t necessary. If you do choose to use a ricer, you must peel your potatoes. So if you prefer mashed potatoes with the skins, use a hand masher or a mixer!
Make sure all your add-ins are room temp! Using room temperature cream cheese is very key, because if it’s cold you will end up with lumps of cream cheese throughout your potatoes. Everything at room temp means the creamiest and smoothest potatoes!
Use fresh grated cheese. I know it’s tempting to buy the pre-grated, fresh grated melts best and makes your potatoes smooth and silky.

Can You Make These Potatoes Ahead?

Absolutely. That’s the great part about this recipe. You can make it and serve right away, OR you can make it hours ahead, and bake before serving. It’s what makes this recipe so great for holidays and entertaining.

Do You Have To Bake Them?

You don’t! Baking allows the extra cheese on top to melt, while giving the flavors a chance to combine and meld. But they are perfectly fine without being baked!

Can You Freeze Mashed Potatoes?

Yep! Make the potatoes up until the step where you bake them. Allow them to cool and cover them with plastic wrap, and then again with foil. Freeze for up to 30 days.

To cook from frozen: Allow the potatoes to thaw out in the refrigerator before baking. And then pull them out of the fridge 20 – 30 minutes before baking to take the chill off.

Same works for leftovers

Store any leftover mashed potatoes in an airtight container and refrigerate for up to 5 days or freeze using the steps above.
