extra large potatoes

ProducePeak harvest occurs in late summer through fall (August–November in Northern Hemisphere); however, properly stored extra-large potatoes remain available year-round in most markets, with supply declining in late spring before new-crop availability.

Extra large potatoes are good sources of potassium, vitamin B6, and manganese, with substantial carbohydrate and starch content; they provide fiber, particularly in skin-on preparations.

About

Extra large potatoes are tubers of the Solanum tuberosum species, typically weighing over 12 ounces (340 grams), with a starchy interior and thin to moderately thick skin depending on variety. These oversized tubers develop longer growing seasons and favorable soil conditions, resulting in a higher starch content and greater volume than standard cultivars. Common extra-large varieties include Russet Burbank, Maris Piper, and Kennebec, each offering distinct characteristics: Russets feature dense, mealy flesh ideal for baking and frying; waxy varieties like Maris Piper maintain shape during cooking and suit boiling and salad applications; and dual-purpose types like Kennebec bridge both categories. The flavor profile ranges from subtly sweet to earthy, depending on variety and terroir.

Culinary Uses

Extra large potatoes are valued for their efficiency in batch cooking and their suitability for rustic presentations. Their substantial size makes them ideal for baking whole, preparing large-format gratins, filling for pierogis and knishes, and creating family-style potato dishes. In professional kitchens and home cooking alike, they serve as the foundation for mashed potatoes, potato salads, and stews, where their volume accommodates larger servings. Starchy varieties (Russets) excel in deep frying for chips and thick-cut fries, while waxy types hold their shape in boiled preparations. The higher starch content of extra-large specimens contributes to superior texture in baked goods and fried preparations.

Forms & Preparations

Whole, unpeeled — Raw potato with skin intact; used for baking, boiling, or roasting for rustic preparations or salads.
Peeled and halved or quartered — Cut for faster, more even cooking in soups, stews, and boiled dishes; reduces cooking time by 10–15 minutes.
Sliced (thin to thick) — Cross-sectional cuts for gratins, scalloped potatoes, chips, or chips (pommes anna); thickness determines final texture.
Cubed or diced — Uniform small pieces for hash, salads, and quick-cooking applications; accelerates cooking significantly.
Mashed or puréed — Cooked, then broken down by hand, fork, ricer, or food mill; base for mashed potatoes, gnocchi, and potato breads.
Shredded or julienned — Fine strands used for hash browns, rösti, or latkes; exposes maximum surface area for crisping.
