Potatoes are one of the most practical vegetables in any kitchen — calorie-dense, long-storing, versatile across every cuisine on earth. But most home cooks use one variety interchangeably across all preparations, which means either baking a potato that turns gluey (wrong variety) or making fries that fall apart (also wrong variety). Understanding the starch spectrum changes how you cook with them.
Varieties worth knowing
Potato varieties fall on a spectrum from high-starch (mealy, fluffy when cooked) to waxy (firm, holds shape when cooked). Most fall somewhere in between.
Russet (Idaho potato) — The high-starch standard. Thick brown skin, white fluffy flesh when baked. The baking potato. Also the frying potato — its low moisture content creates the crispiest fries. Breaks down when boiled (which makes it wrong for potato salad and good for mashed potatoes if you want a fluffy result rather than a creamy one).
Yukon Gold — The most versatile medium-starch potato. Buttery yellow flesh with a naturally rich flavor that needs less butter and cream to achieve creaminess. Excellent for mashing, roasting, gratin, boiling, and pan-frying. The go-to for most cooking where you want both flavor and some structure.
Red potatoes — Waxy, low-starch, with thin red skin. Holds shape beautifully when boiled — the right choice for potato salad and any preparation where you need intact cubes or slices. Less starchy than Yukon Golds. Good for roasting and soups.
Fingerling potatoes — Small, elongated, often knobby heirloom varieties (Russian Banana, French Fingerling, Purple Peruvian). Waxy and firm with concentrated flavor. Best roasted whole or halved, or boiled and dressed simply. Often more flavorful than large varieties. Common at farm stands.
New potatoes — Any variety dug early, before the skins have fully set. Paper-thin skin, very creamy, delicate. Best boiled or steamed and served with butter and herbs. Do not store well — use within days of purchase. A genuine seasonal treat from local farms.
Purple and blue potatoes — All-purpose with a slightly nutty flavor and striking color. Holds shape well. The color fades in boiling water but holds better in roasting. Worth trying when available.
White potatoes (White Rose, Kennebec) — Medium-starch, multipurpose, mild flavor. Common in restaurant kitchens for their consistency. Less interesting than Yukon Gold but dependable.
When potatoes are in season
New potatoes (summer, June – August): Freshly dug, thin-skinned, only at farm stands and farmers markets. A genuine seasonal treat that supermarkets never carry.
Fresh-dug storage potatoes (September – October): Fall harvest. Farm stands often have the widest variety selection at this time of year. Skin is set but the potato is still relatively fresh.
Storage potatoes (November – June): Potatoes from cold storage. Properly stored potatoes last 6 to 9 months, making them one of the best sources of local produce in winter and spring.
Potatoes are available year-round from local farms with proper storage infrastructure — making them one of the most reliable local purchases through every season.
How to pick potatoes at the market
Look for: Firm potatoes with smooth, unblemished skin. No green patches (greening indicates solanine development from light exposure — cut away generously). No sprouts, though a small sprout can be removed without compromising the potato.
Avoid: Soft spots (internal decay), deep cracks, heavy bruising, or any green color. A potato that is soft all the way through should be discarded.
At a farm stand: Ask about variety and intended use — most farmers who grow multiple varieties know which is best for baking, frying, boiling, and roasting. Ask about new potatoes in early summer.
How to store potatoes
Store potatoes cool, dark, and dry — not in the refrigerator. Ideal temperature is 45–50°F (7–10°C), which is cooler than room temperature but warmer than a refrigerator.
Do not refrigerate: Cold converts potato starch to sugar and causes problematic browning when cooked.
Keep away from light: Light triggers greening and solanine production. A paper bag, dark pantry, or covered bin works.
Keep away from onions: Onions emit gases that accelerate sprouting in nearby potatoes.
Ventilation: Potatoes need airflow. Mesh bags and paper bags work better than sealed plastic.

How to use potatoes
Baked: Russets are the right choice. 400°F (200°C) for 60 minutes. Pierce before baking. Rub with oil and salt for crispy skin. The internal temp should reach 210°F (99°C) for full fluffiness.
Mashed: Yukon Golds for creaminess, Russets for lightness. Boil until a fork passes through with no resistance. Drain thoroughly — residual moisture makes glue. Warm the butter and cream before adding to prevent cooling the mash.
Roasted: Par-boil cubed potatoes 8 minutes, drain, shake in the pot to roughen the edges, roast at 425°F (220°C) in hot oil. The roughened surface gets dramatically crispier.
Pan-fried: Parboiled or leftover boiled potatoes sliced and cooked in a cast iron skillet until golden. See our pan-fried potatoes recipe.
Potato salad: Use waxy red potatoes or fingerlings — they hold shape when cooled. Dress while warm so the potato absorbs the vinaigrette.
Gratin (dauphinoise): Thin-sliced Yukon Golds layered with cream and garlic, baked until golden. Medium-starch potatoes hold shape while absorbing cream.
Soup: Potatoes add body and starch to any soup. Yukon Golds or whites dissolve partially to thicken; reds and fingerlings hold their shape in chunky soups.
Flavor pairings
- Butter — The foundational pairing. Brown butter adds nuttiness.
- Rosemary and thyme — The classic roasted potato herbs.
- Garlic — Works with potatoes in every preparation.
- Chives and sour cream — The loaded baked potato combination.
- Smoked paprika — Excellent on pan-fried or roasted potatoes.
- Lemon and parsley — A bright finish for roasted or boiled potatoes.
- Bacon and onion — German-style potato salad; works with almost any hot potato preparation.
- Cheddar — The classic gratin cheese; also essential for the loaded potato.
- Olive oil and salt — Enough when the potato is good. New potatoes in summer need nothing more.
- Vinegar — A splash of cider or white wine vinegar over hot potatoes, then add the rest of the dressing — the potato absorbs more flavor this way.
