What Are The Best Potatoes For Mashing? 

Choose higher starch potatoes like Yukon Golds or Russets for flavor-packed, fluffy, and smooth mashed potatoes. Medium-starch Yukon Gold and other yellow-fleshed potatoes naturally have a buttery flavor along with a creamy, dense consistency. High-starch Russet potatoes have an earthy flavor and mash up light and fluffy.

Yukon Golds absorb less water as they cook than most other potatoes, so they’re less likely to get water-logged or gummy. Try roasting Russets instead of boiling to ensure they don’t take on too much water.

The higher the starchiness the lighter and fluffier the mashed potatoes. Yukon Golds will produce super creamy, dense mashed potatoes, while russets turn out fluffy and soft. Avoid waxy red potatoes for mashing they have firmer flesh and require more mashing, which could lead to “gluey” potatoes.

Still can’t decide which potatoes are best for mashing? Why not use a combination of Russets and Yukon Golds and get the best of both worlds!

Creamy Mashed Potatoes Ingredients

I love that I can whip up these mashed potatoes ahead of time and serve them with dinner the next day. With simple ingredients, you’ll love this easy side dish too. Here’s what you need:

  • Potatoes– You can use Yukon Gold, Russet, or a combination of the two. Make sure to peel and cube them. 
  • Cream cheese– For best results, leave the cream cheese on the counter for 30-minutes to soften it. 
  • Heavy cream and milk– You can use half heavy cream and half milk, or you can just use milk. Whichever you use you will want them to be warm when adding to the potatoes.
  • Salt and pepper– These add a little flavor. You could also add in some garlic powder or your favorite spices. 
  • Butter- I use unsalted butter, but you can use salted as well. Divide the butter in half as you will use half now and half when you bake the mashed potatoes. 
  • Chives or thyme– These are totally optional, but are super yummy to garnish your potatoes with.

How to Make Easy Mashed Potatoes Ahead of Time

(full printable recipe at the end of this post)

Although these are make-ahead mashed potatoes, you can finish the recipe and make them on the same day. Or you can store them in the refrigerator and bake them later. It just depends on when you need them. 

Boil the potatoes: After you have peeled and cubed the potatoes, you will need to boil them. Place them in a pot covered with water and boil them for about 15 minutes. 

Drain and mash the potatoes: Once the potatoes are tender but still firm, drain and mash them. You can mash them right in the pot you used to cook them in. 

Blend ingredients: Next, put your mashed potatoes, cream cheese, milk (or milk and cream), butter, salt and pepper into a mixing bowl. Mix the ingredients until blended thoroughly. 

Store for later: Put your mashed potatoes in a large casserole dish and cover with plastic wrap or aluminum foil. Then, put it in the refrigerator until ready to reheat. 

Preheat and prep: When you are ready to eat your mashed potatoes, heat the oven to 350℉. Let the potatoes sit at room temperature for half an hour. 

Bake the mashed potatoes: Dot the top of the mashed potatoes with butter. Then, bake them covered with aluminum foil for 30-minutes. Uncover the mashed potatoes and bake them for another 15-20 minutes. This will allow the top of the mashed potato to crisp up a bit. 

Garnish: Remove after they are done cooking and cool slightly. Garnish your mashed potatoes with your favorite toppings such as freshly chopped chives, thyme, sour cream, or bacon bits. 

Serve and Enjoy!

Recipe FAQs

Do I need to peel the potatoes for mashed potatoes?

Many chefs recommend that you peel your potatoes before you mash them as it will produce fluffier, creamier mashed potatoes. However, there are many recipes for mashed potatoes in which the skin is left on the potato. In fact, the skin has most of your vitamins and nutrients in it. For this recipe, we peeled them, but that is totally up to you. 

What type of potatoes are best for mashed potatoes?

I personally find that Yukon Golds are the best potatoes for mashed potatoes. They are naturally creamy when you mash them, never gritty, and even have a slight butter flavor on their own. However, Russet or Idaho potatoes work as well. 

What is 2 pounds of potatoes?

Most potatoes come in 5 pound bags, but this recipe calls for 2.5 pounds of potatoes. 2 pounds of potatoes is approximately 6 medium potatoes. So, to get the 2.5 pounds, you will want to use 7-8 medium-sized potatoes.

Pro Tips For The Best Mashed Potatoes

Use chicken broth: Instead of boiling your potatoes in water, boil them in 4-6 cups of chicken broth for even more delicious flavor. After mixing, make sure to test the flavor before adding more salt. 

Do NOT add cold milk/cream: Make sure the milk or cream you add to your potatoes is warm to hot. This will help it absorb better into the hot potatoes avoiding the need to over mix.

Add garlic salt: If you like garlic mash, add a little garlic salt to your mashed potatoes while mixing all the other ingredients. 

Remove excess water: After boiling, drain the potatoes and put them back in the pot without a lid. Set them back on the hot burner for a few minutes, shaking the pot, until all the excess moisture on the potatoes has evaporated. 

Don’t overmix mashed potatoes: Potatoes are full of starch, and if handled too much your mashed potatoes will become gooey.

Use an electric mixer: If you prefer creamy and smooth mashed potatoes, use an electric mixer when mashing the potatoes and blending the ingredients. 

Use a hand masher: If you like your potatoes a little lumpy, use a hand masher instead of the electric mixer. This will leave you with a few chunks of potatoes to enjoy.

  • freshly chopped chives or thyme for garnish (optional)

Instructions
