Baked Mashed Potatoes Are Our Favorite Side Dish!

We have been eating a lot of comfort food lately, and mashed potatoes have been a once a week side dish we’re enjoying. They might not be beach-bod-friendly, but during quarantine I’m finding there are definitely new rules!

These mashed potatoes are unbelievably creamy, flavorful, and easy. They have 2 different cheeses mixed in AND a little more on top. There isn’t anyone who has tried these and hasn’t loved them. Plus, you can make them ahead which is a great timesaver.

What Kind Of Potatoes Are Best For Mashed Potatoes?

For this recipe I recommend Russet Potatoes.

Russet Potatoes are more starchy and give you the creamiest mashed potatoes. The soak up the butter and milk nicely and make the silkiest, smoothest mashed 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?

In this recipe I use a combination of cream cheese and 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

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.

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.

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.

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.

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!
