Potato Varieties: Which Potato for Which Dish
Russet, Yukon Gold, red, fingerling, and the rest — how starch content determines behavior, and the variety-to-method pairings that never fail.

Most potato failures are variety failures committed before the stove is lit. A russet in a salad falls apart; a red potato in a mash stays gritty. The fix is one piece of knowledge: potatoes run along a starch spectrum, and each point on the spectrum has a method that flatters it.
The spectrum
Starchy (floury) — russet, Idaho, Maris Piper. High amylose, low moisture, cells that separate cleanly when cooked. These are the breakdown-prone, flavor-absorbing potatoes: baking (the interior fluffs), mashing (absorbs dairy), french fries (interior goes mealy-light while the exterior crisps). They fall apart in anything with liquid.
All-purpose — Yukon Gold, Kennebec, Desiree. Medium starch, naturally dense and slightly buttery (Yukon Gold's carotenoids give the color). The workhorses: roasting (crisp outside, dense inside), gratins (hold structure, absorb cream), pan-frying, soups where some body is welcome. If you buy one potato, buy this one.
Waxy — red bliss, new potatoes, fingerlings, Charlotte. Low starch, high moisture, thin skins, cells that stay sealed. They hold shape under any abuse: salads (dressed chunks, not mush), boiling, braises, stews, smashing-and-roasting. They make dense, gluey mash and sad bakes.
Pairings that never fail
| Dish | Variety | Why |
|---|---|---|
| Baked potato | Russet | Maximum fluff from amylose |
| Mashed potatoes | Russet or Yukon Gold | Absorption vs. density tradeoff |
| Potato salad | Red bliss, fingerling | Holds shape under dressing |
| Roast potatoes | Yukon Gold | Crisp + creamy in one bite |
| French fries | Russet (Kennebec classically) | Mealy interior, crisp exterior |
| Gratin dauphinois | Yukon Gold | Slices stay intact, absorb cream |
| Soup | Any; waxy if chunks wanted | Starch bodies the broth |
| Gnocchi | Russet | Dry, floury flesh = light dough |
Buying and storing
Firm, unblemished, no green, no long sprouts. Waxies are often sold immature ("new potatoes") — thin-skinned and best simply boiled with butter. Store all varieties dark, cool (7–13°C), ventilated, away from onions; refrigeration sweetens them (starch→sugar conversion) and ruins fry color (how to cook potatoes covers the chemistry).
