Understanding the Three Main Potato Categories
Before diving into specific varieties, it is essential to understand the core categories based on their starch content: starchy, waxy, and all-purpose. A potato's starch level dictates how it behaves when cooked, determining whether it will become fluffy and absorbent or hold its shape firmly.
Starchy Potatoes: The Key to Fluffiness
Starchy potatoes have a high starch and low moisture content. This combination causes their cell walls to separate and break down easily when cooked, resulting in a dry, mealy, and fluffy texture. This characteristic makes them perfect for absorbing toppings and creating a light consistency.
- Russet (or Idaho) Potatoes: The quintessential baking and mashing potato, known for its thick skin and fluffy interior. Their high starch content makes them the top choice for crispy french fries, hash browns, and for thick potato soups.
- King Edward: A traditional starchy British variety known for producing an exceptionally fluffy result when baked or roasted.
- Sweet Potatoes: While botanically distinct, sweet potatoes have a starchy texture and a high beta-carotene content, which is converted to vitamin A in the body. They are excellent for baking, roasting, and mashing into a vibrant, flavorful dish.
Waxy Potatoes: The Shape-Shifters
In contrast, waxy potatoes have low starch and high moisture, with a thin skin. Their cells remain intact during cooking, allowing them to hold their shape exceptionally well. This makes them the ideal choice for recipes where you want a firm, creamy texture.
- Red Potatoes (or Red Bliss): With their thin, red skin and firm, creamy flesh, these are perfect for boiling and retaining their structure in potato salads, soups, and gratins.
- New Potatoes: A general term for any potato harvested early, new potatoes are small, firm, and waxy. They are excellent boiled, roasted, or used in salads where their texture is prized.
- Fingerling Potatoes: Small and finger-shaped, these potatoes have a waxy texture and thin skin. They are delicious when roasted or pan-fried, holding their shape and developing a flavorful, crispy exterior.
All-Purpose Potatoes: The Versatile Choice
All-purpose potatoes strike a balance between starchy and waxy, making them a kitchen standby. They offer a creamy texture when mashed but can still hold their shape when roasted or boiled.
- Yukon Gold: Arguably the most popular all-purpose potato, Yukon Golds offer a rich, buttery flavor and creamy texture. They are excellent for mashing, roasting, and in soups and chowders.
- Desiree: This red-skinned, creamy-fleshed variety is a fantastic all-rounder, performing well when roasted, chipped, or mashed.
The Healthiest Potatoes: Beyond the White Spud
While all potatoes offer nutritional benefits like potassium, vitamin C, and fiber, some varieties pack an extra punch, particularly those with deep, colorful flesh.
- Purple Potatoes: These vibrant potatoes are rich in anthocyanins, powerful antioxidants also found in blueberries. Studies have shown that purple potatoes can have anti-inflammatory properties and may help lower blood pressure.
- Sweet Potatoes: A nutritional powerhouse, sweet potatoes provide a massive dose of beta-carotene, an antioxidant vital for eye health and immunity.

| All-Purpose | Mashing, Roasting, Soups, Grilling | Medium starch; creamy but holds shape | Yukon Gold, Desiree |
| Colorful | Roasting, Mashing, Baking | High in specific antioxidants like anthocyanins or beta-carotene | Purple Potatoes, Sweet Potatoes |
Making the Best Choice for Your Cooking
The ultimate answer to what is the best potato you can eat isn't a single variety but the right variety for your recipe. For crispy fries, a baked potato with a fluffy center, or a smooth mash, a starchy russet is your best bet. If a recipe calls for a potato that holds its shape, like a potato salad or hearty soup, a waxy red potato or fingerling is ideal. For a versatile go-to that offers a buttery flavor and works well in many dishes, the Yukon Gold is a fantastic choice.
Don't forget the nutritional advantages of colorful potatoes. Incorporating purple or sweet potatoes into your diet offers a powerful antioxidant boost alongside their great taste. Regardless of the type, preparing potatoes healthily—by boiling, baking, or roasting rather than frying—and eating the nutrient-rich skin maximizes their benefits.
