How Do You Boil Different Types Of Potatoes?

High Starch Content

Potatoes with a high starch content are the best for mashing. Starchy potatoes do not hold their shape well after boiling, so they will mash beautifully. Boil russets for about 15 to 20 minutes or until fork-tender.

Russets

Russets are the ideal choice for making super fluffy mashed potatoes. Their high starch content means that they'll whip up smooth and absorb ingredients like cream, butter, and milk exceptionally well. Chef John's Perfect Mashed Potatoes recipe uses russets and whole milk for super creamy results.

Sweet Potatoes

Mashed sweet potatoes are so versatile because you can easily make them sweet with a few sprinkles of brown sugar and cinnamon or savory with a pat of butter and some roasted garlic. Try this decadent Cinnamon Honey Butter Mashed Sweet Potatoes recipe for a delicious combination of flavors.

Medium Starch Content

Potatoes with a medium starch content are often referred to as all-purpose because they work well for baking, frying, and of course, mashing. All-purpose spuds will mash denser than the higher starch varieties and usually boil in 20 to 25 minutes.

Yukon Gold

Low Starch Content

Potatoes with a low starch content are also called waxy potatoes. These potatoes hold their shape well and are perfect for potato salad. However, if you like mashed potatoes with a chunkier consistency, these potatoes are right for you! Boil them for approximately 10 to 15 minutes and mash with a handheld masher for the best results.

How Do You Know When A Potato Is Done Boiling And Ready To Be Mashed?

Potatoes are done boiling and are ready to mash when they are fork-tender. Poke a couple of pieces of cooked potatoes; if the fork glides easily through, then your potatoes are thoroughly cooked and are ready to be mashed. You can also check the internal temperature using a food thermometer. If the temperature reads around 212 degrees Fahrenheit, your potatoes are ready to go.

Can You Boil Potatoes Ahead Of Time For Mashing?

Yes, you can easily boil potatoes ahead of time for mashing. After boiling potatoes in salted water, thoroughly drain and let cool. Place cooled potatoes in an airtight container or a bowl tightly wrapped with plastic wrap and stored in the fridge for up to three days.

When it's time to mash the potatoes, warm them up in the microwave for a few minutes to knock the chill off. Now you're ready to add butter, milk, and seasonings to create perfect mashed potatoes.

How Do You Boil Potatoes Quickly?

If you're strapped for time and need to boil potatoes quickly, several methods will help you achieve your goal.

  • Cut the potatoes in chunks. Cutting potatoes in equal-sized pieces means that they'll cook at a much faster rate than they would if left whole.
  • Cook them in the microwave. You can place cubed potatoes in a microwave-safe bowl, cover with water, and cook in two to three minute increments until they are fork-tender.
  • Boil water beforehand. Place water in a teakettle and bring to a boil. Then, pour the boiled water over cubed potatoes in a pot and cook for about 10 minutes.

Can You Over Boil Potatoes?

You probably already know that it's possible to overboil potatoes for dishes like potato salad when the potatoes need to stay intact but end up mushy, but can you overboil potatoes when you're just going to mash them anyway? Surprisingly, yes. Spuds boiled for too long will make for overly soupy mashed potatoes because potatoes absorb a lot of water when overcooked.

Should You Cover Boiling Potatoes?

It's a good idea to leave the lid off of your pot, at least while the water reaches the boiling temperature. After the water has come to a full boil, reduce the heat to medium-low, cover with the lid, and simmer for 15 to 20 minutes. Allowing the potatoes to simmer with the lid on will result in even heat distribution and faster cooking time.
