Roscoff onions, also known as pink Roscoff onions, are a celebrated heirloom variety from Brittany, France, prized for their sweet, mild flavor and striking copper-pink skin.

Origin Story

These onions hail from the Finistère region, particularly around Roscoff, Saint Pol de Léon, and Morlaix, where they've been cultivated since the 17th century. Maritime trade played a key role in their fame—Breton "Johnnies" peddled them across the English Channel in the 19th century, braiding them for easy transport and sale, which helped prevent scurvy among sailors due to their vitamin C content. Today, they hold Protected Designation of Origin (PDO) status, ensuring authentic production in this coastal microclimate.

Distinctive Traits

Roscoff onions typically measure 4-8 cm in diameter with a round to oblate shape, featuring thin, papery copper-pink layers over firm, juicy, white flesh tinged pink. Raw, they offer a crunchy texture, subtle sweetness, and fruity pungency; cooking transforms them into a mellow, savory delight that pairs beautifully with meats and tarts. Harvested July to September with at least 5 cm of stem attached, they're often sold in traditional hand-braided strings for long storage.

Culinary Uses

  • Raw applications : Slice into salads, top burgers, or mince for dressings—their piquant sweetness shines without overpowering.
  • Cooked delights : Sweat slowly for tarts (like the classic French onion tart with crème fraîche and thyme), stews, or Breton meat dishes where their persistent aroma elevates flavors.
  • Pro tip : Peel under running water to minimize eye irritation from volatile compounds.

Nutritional Perks

Packed with fiber for digestion, plus manganese, copper, phosphorus, iron for bone health and oxygen transport, and vitamins B, C, K for immunity and energy. Their quick-cooking nature makes them versatile for modern kitchens seeking gourmet results.

Trending Context

No major latest news or viral forum buzz as of January 2026, but their resurgence in specialty recipes—like upscale tarts and PDO-protected imports—keeps them a chef favorite in Europe and beyond. Discussions on sites like Slow Food highlight preservation efforts amid climate challenges.

TL;DR : Roscoff onions are Brittany's sweet, pink gems—versatile, storable, and PDO-protected for authentic flavor in raw or cooked dishes.
