Potatoes show up in an enormous range of foods, from obvious ones like french fries to less expected products like vodka, gluten-free baked goods, and plant-based burger patties. In the United States alone, about 270 million hundredweight of potatoes go to processing each year, compared to roughly 99 million hundredweight sold fresh for home cooking. That means most potatoes grown in this country end up transformed into something else entirely before they reach your plate.
Classic Cooked Potato Dishes
The simplest potato foods are the ones you make at home: baked potatoes, mashed potatoes, boiled potatoes, roasted potatoes, and potato salad. These preparations differ more than you might think. A baked russet potato has a glycemic index around 111, while french fries come in much lower at about 64. The reason is that different cooking methods change the internal starch structure in different ways, affecting how quickly your body converts that starch to sugar.
Beyond the basics, potatoes anchor dozens of traditional dishes around the world. Gnocchi are small Italian dumplings made from mashed potato mixed with flour and egg. Pierogi are Eastern European filled dumplings where potato (often blended with cheese or onion) is the most common stuffing. Latkes are crispy pan-fried pancakes made from grated raw potato, a staple of Jewish cuisine. Colcannon is an Irish dish of mashed potato folded together with cabbage or kale. Poutine, from Quebec, layers french fries with cheese curds and gravy. Rösti is a Swiss pan-fried potato cake similar to a giant hash brown. Spanish tortilla is a thick egg-and-potato omelet served at room temperature.
Chips, Fries, and Packaged Snacks
Potato chips and french fries are the two biggest categories of processed potato products. Standard chips are thin-sliced and fried, but the category extends to kettle-cooked chips, ridged chips, stacked chips (like Pringles, which are made from dehydrated potato flakes pressed into a uniform shape), and baked chip varieties. Frozen french fries, tater tots, hash browns, and potato wedges make up another massive segment of the freezer aisle.
Some potato snacks are extruded, meaning potato starch or flour is forced through a machine to create puffed or shaped products. These include potato-based puffs, sticks, and curly snack shapes that look nothing like a potato but are largely made from one. Manufacturers also use potatoes in frozen appetizers like potato skins, loaded potato bites, and stuffed potato products.
Potato Starch and Flour in Packaged Foods
Potato starch is one of the food industry’s most versatile ingredients, and it appears in products you’d never associate with potatoes. It works as a thickener in sauces, gravies, dry soup mixes, and salad dressings. It binds moisture in processed meats like sausages and deli slices. It coats fried foods in batters and breadings to create a crispier texture. It shows up in pudding mixes, confectionery, cereals, and even pet food.
Potato flour, which is made from whole cooked potatoes rather than just the extracted starch, serves a different purpose. It adds moisture and a soft texture to baked goods, making it especially popular in gluten-free baking. Gluten-free breads, muffins, pancake mixes, and pizza crusts frequently list potato starch or potato flour on their ingredient labels. You can substitute potato starch for cornstarch in most recipes at a 1:1 ratio.
Dehydrated Potato Products
Instant mashed potatoes are made from potatoes that have been cooked, mashed, and then dried into flakes or granules. These same dehydrated potato flakes are also the base ingredient in many boxed scalloped potato and au gratin mixes. Potato flour, dried potato soup mixes, and shelf-stable potato-based side dishes all rely on dehydration to extend shelf life. Some backpacking and emergency food kits lean heavily on dehydrated potato products because they’re lightweight, calorie-dense, and rehydrate easily.
Alcoholic Beverages
Potatoes are a traditional raw material for distilled spirits. Vodka is the most well-known potato-based alcohol, though most commercial vodkas today are actually made from grain. Potato vodkas have a distinct, slightly creamy mouthfeel compared to grain-based versions. Aquavit, the national spirit of Scandinavian countries (called akevitt in Norwegian and akvavit in Danish), is also traditionally distilled from potatoes and flavored with caraway or dill. It typically ranges from 37.5% to 50% alcohol by volume. Some craft distilleries also produce potato-based gin, whiskey-style spirits, and even potato wine.
Plant-Based Meat and Newer Uses
Potato protein isolate, recovered from the wastewater of industrial potato processing, has become a valuable ingredient in plant-based meat alternatives. It has an amino acid profile, digestibility, and functional properties (like the ability to emulsify and foam) that are comparable to egg white and dairy proteins. Some vegan burger formulations use potato protein as the primary ingredient, with one research recipe using a blend of 70% potato protein alongside smaller amounts of rice, wheat, and pea protein to create a patty that mimics the texture of ground beef.
This makes potato protein attractive to food manufacturers looking for clean-label, allergen-friendly ingredients. Unlike soy or wheat protein, potato protein sidesteps some of the most common food allergen concerns while still delivering strong nutritional value and the structural properties needed to hold a burger together.
Which Potato Varieties Go Where
Not all potatoes are created equal, and the food industry selects specific varieties for specific products. Mealy, high-starch varieties like Russet Burbank and Michigold have a dry, fluffy texture that makes them ideal for baking, mashing, and frying into french fries. Waxy varieties like Red Gold hold their shape when cooked, so they’re preferred for boiling, roasting, and potato salads where you want firm, intact pieces.
Yellow-fleshed potatoes occupy a middle ground. Varieties like Yukon Gold work well both as fresh table potatoes and in processing. Specialty colored potatoes (purple, pink, and blue varieties) are increasingly showing up in chip production, where their unusual color becomes a selling point. A variety called Saginaw Gold was specifically bred to produce chips with good color and flavor.
