Cooking With Potatoes: How to Choose the Right Potato for Every Cooking Method
Potatoes can be baked until fluffy, mashed until creamy, roasted until crisp, simmered in soups or sliced into gratins and salads. The best results begin with choosing a potato whose starch and moisture level fit the cooking method.
This guide breaks potatoes into three practical groups—starchy, waxy and all-purpose—and explains which types work best for baking, mashing, roasting, boiling and frying.
Starchy, Waxy, and All-Purpose Potatoes
Potato varieties differ in starch and moisture. Starchy potatoes tend to cook up dry and fluffy. Waxy potatoes have a denser, creamier texture and hold their shape well. All-purpose potatoes fall between those extremes and can handle a wide range of preparations.
Starchy Potatoes
Russets are the classic example. Their high starch and relatively low moisture make them especially good for baked potatoes, fluffy mashed potatoes, fries and other preparations where a dry, light interior is desirable.
Best Potatoes for Mashed Potatoes
Russets produce particularly fluffy mashed potatoes because their cooked cells separate readily. Yukon Gold potatoes produce a denser, naturally creamy mash and are also an excellent choice. You can combine the two when you want both fluffiness and buttery texture.
Cut potatoes into similar-sized pieces and begin them in cool salted water so the centers and exteriors cook more evenly. Simmer rather than aggressively boil. Drain thoroughly, let excess steam escape, then rice or mash while hot.
The most important rule is not to overwork them. Vigorous stirring or processing can release excessive starch and make mashed potatoes gluey. Warm butter and milk or cream before folding them into the potatoes so the mash stays hot.
For smooth potatoes with minimal working, a potato ricer is especially useful.
Best Potatoes for Baking
A large russet is the classic baking potato because its skin can become crisp while the interior turns dry and fluffy. Scrub and dry the potato, pierce it a few times, and bake it uncovered so moisture can escape.
Internal temperature can be a useful secondary check for a very large baked potato, but texture is the goal: a skewer or knife should slide through the center easily and the inside should be soft and steaming. For more detail, see Mastering the Art of the Perfect Baked Potato.
Waxy Potatoes
Waxy potatoes have relatively low starch and higher moisture. They stay intact after cooking, which makes them useful when you want recognizable slices or chunks rather than a potato that breaks apart.
Red potatoes, fingerlings and many small potatoes fall toward the waxy end of the spectrum. They are particularly good for boiling, steaming, potato salad, soups, stews, gratins and roasting.
“New potato” describes a potato harvested young rather than one specific variety. These potatoes tend to have thin skins and a moist, firm texture.
Waxy potatoes are useful for dishes where the pieces need to hold their shape after simmering.
All-Purpose Potatoes
All-purpose potatoes have a middle-of-the-road balance of starch and moisture. Yukon Gold is a familiar example. These potatoes can be boiled, roasted, mashed, baked, sautéed or used in casseroles.
When a recipe does not specify a variety, an all-purpose potato is often the safest choice because it offers enough starch for browning while still holding together reasonably well.
Best Potatoes for Roasting
Both all-purpose and waxy potatoes can roast beautifully. Yukon Golds develop crisp edges with creamy centers. Red potatoes and fingerlings hold their shape especially well. Russets can become exceptionally crisp but are more fragile once cooked.
For better browning, dry the cut potatoes well, coat them evenly with oil, give them enough room on the pan and use a hot oven. Crowding traps steam and works against crispness.
Potatoes for Soups, Stews, and Gratins
Choose according to the texture you want. Waxy potatoes stay in neat pieces through simmering. Starchy potatoes can soften and release starch, helping thicken the surrounding liquid. All-purpose potatoes offer a compromise between the two.
For scalloped potatoes and gratins, a potato that can be sliced evenly and soften without completely disintegrating is useful. Try Parmesan Scalloped Potatoes.
Frequently Asked Questions
Do potatoes need to be rinsed before cooking?
Wash whole potatoes to remove dirt. Cut potatoes can also be rinsed when you specifically want to remove surface starch, such as before making some fries or roasted potatoes. Rinsing cooked potatoes is not a general requirement.
Why do mashed potatoes turn gluey?
Overworking cooked potatoes releases too much starch. Mash or rice them while hot and mix in the butter and dairy gently rather than whipping them aggressively.
Which potato is the most versatile?
Yukon Gold is one of the most useful all-purpose choices because it can be mashed, roasted, boiled, sautéed and used in gratins while maintaining a creamy texture.
