Easy Make Ahead Mashed Potatoes in the Oven

A great way to save time with Christmas dinner is to make these easy make ahead mashed potatoes. Just as creamy and delicious as traditional mashed potatoes, this is a side dish you will make again and again.

CAN I PEEL POTATOES AHEAD OF TIME?

The whole point of making mashed potatoes ahead of time is to save time on a busy cooking day like Thanksgiving or Christmas. 

Another way to save time is to actually peel the potatoes the day before you plan to use them. 

Peel the potatoes you will need for your mashed potatoes and place them in a big bowl or pot and cover them completely with water. Keep the pot in the refrigerator for hours or even overnight.

The water will keep the potatoes from getting brown.

WHICH VARIETY OF POTATOES WORK BEST IN MAKE AHEAD MASHED POTATOES?

There are actually over 200 varieties of potatoes sold in the US. That is a lot of choices when it comes to picking a good potato to cook with.

Different types of potatoes vary in taste, texture, moisture and more. It is important to use the right types of potatoes to get the best results when it comes to mashed potatoes.

The best potatoes to use in this creamy make ahead mashed potato recipe are golden potatoes or russet potatoes. They yield the creamiest and fluffiest results.

CAN I USE A SLOW COOKER?

If you don’t want to make these potatoes in the oven because you are too busy making the stuffing it is totally understandable! 

Instead of transferring the mashed potatoes to a baking dish just transfer them to a slow cooker that has been buttered on the inside of the pot. Set the slow cooker to warm and you are done! 

When it is time to eat give the potatoes a stir and if needed add some more butter!

HOW TO MAKE MASHED POTATOES AHEAD OF TIME

The beauty of making mashed potatoes ahead of time is that it frees up your time for other last-minute preparations. 

STEP ONE: BOIL POTATOES

Chop the potatoes into big chunks and place in a large pot. 

Add water to the pot until the potatoes are completely covered. 

Place the pot on the stove and turn to medium-high. Bring the potatoes to a boil and boil until they are fork-tender.

When the potatoes are tender, drain the water.

STEP TWO: MASH POTATOES

Use a potato masher or mixer to mash the potatoes until they are almost lump-free. 

STEP THREE: ADD INGREDIENTS

Now add the softened cream cheese, softened butter, sour cream, garlic powder, onion powder, salt and pepper to the mashed potatoes and whisk these ingredients together until smooth.

Add the milk to the mixture and whisk it in.

STEP FOUR: ADD TO BAKING DISH

Now that the mashed potatoes are mixed it is time to add the mixture to a 9 x 13 baking dish. 

Cover the dish tightly with foil and place in the refrigerator until ready to bake.

STEP FIVE: BAKE

Preheat the oven to 350°F. 

Place the covered baking dish in the oven and bake for 30 minutes with the foil still on.

Remove the foil after 30 minutes and bake an additional 10 minutes so the top gets crispy.

Garnish with finely chopped chives, if desired.
