Island vegetables, treasures of the islands enhanced by Groix & Nature
The soul of our artisan cannery beats to the rhythm of the ocean, but it also draws its strength from the fertile soil of our Breton islands. Beyond our seafood recipes, we are committed to promoting the island vegetables that make our region so rich. As a committed local player, Groix & Nature promotes the expertise of island producers through artisanal and creative recipes.
The Oyster Mushrooms of Belle-Île
Lionel Feuillu's oyster mushrooms are hardy mushrooms, a far cry from standard cultivated varieties. Their slow growth, in the cool darkness and constant humidity of the blockhouse, gives them exceptionally dense flesh that is not very spongy. Their deep pearl grey colour hides an intense forest floor aroma and a structure that does not fall apart. This is a noble product that offers a generous, almost forest-like texture.

Our producer's expertise: In Belle-Île-en-Mer, they are carefully cultivated in the casemates of Vauban's ramparts in Le Palais, a historic site perfectly suited to mushroom growth. The secret to this cultivation? An island market gardening technique based on the circular economy. The producer collects coffee grounds from the island's bars to create a rich, natural compost. This artisanal expertise enables local production while making the most of the region's resources.
Our artisanal recipe: To preserve this intact texture, we have created our Belle-Île Oyster Mushroom and Organic Buckwheat Spread. We preserve real pieces so that you can enjoy the firmness of the mushroom in your mouth. The roasted buckwheat emphasises this wild flavour, creating a balanced recipe where each ingredient retains its personality. It is the very expression of our plant-based gastronomy.

Groix Beetroots
Beetroots cultivated by the Guelous are roots with character, forged by the sandy soil of Port-Mélite. Unlike beetroots grown on flat land, they are smaller, denser and less watery. Their constant exposure to sea spray forces the vegetables to concentrate their sugars for protection, resulting in extremely dark, almost black flesh. Their taste is paradoxical: a powerful earthy sweetness, coupled with a hint of natural iodine.

Groix Red Kuri Squash
The Red Kuri Squash grown by Isabelle and Yves Guelou embody all the uniqueness of Groix’s terroir. Their thick, velvety flesh develops a naturally sweet flavour with delicate chestnut notes. Exposed to sea winds and nourished by the island’s well-draining soils, they are more concentrated and less watery than mainland-grown squash, revealing a uniquely comforting roundness.

Groix Chilli Pepper
It is a fruit with thin, taut skin that changes colour from green to bright red. What makes it special? A perfect balance between heat and fragrance. It has a lively but short heat, which quickly fades to give way to aromas of candied red fruits and roasted peppers. It is a chilli pepper that awakens the palate without ever numbing it.

Our producer’s expertise: On the heights of Groix Island, beetroots, Red Kuri squash and chillies are grown in organic polyculture by a dedicated market gardener who carefully selects heirloom seeds capable of withstanding summer droughts and adapting to the island’s well-draining soils. Grown without pesticides or chemical fertilisers, these vegetables are harvested by hand in tune with the seasons to preserve their full aromatic richness. After harvest, the chillies are slowly dried and then ground into powder directly on Groix to retain the finesse of their aromas. This artisanal expertise supports sustainable local sourcing, in line with Groix & Nature’s CSR commitments towards more responsible food production.
Our artisanal recipes: In our Organic Groix Beetroot and Red Lentil Spread, the intensity of the beetroot provides our only natural colouring: its natural sweetness balances the texture of the lentils, with no added sugar. The Organic Groix Red Kuri Squash and Chickpea Spread showcases the full roundness of this island-grown squash, whose melting flesh blends with the richness of chickpeas, enhanced by a hint of curry for a warm and indulgent plant-based recipe. Our Organic Sardine Rillettes with Groix Chilli, made from sardines caught in Brittany and slowly confit in our workshop, are elevated by a touch of locally grown organic chilli, creating a subtly spiced marine flavour that enhances both fish and vegetables in our recipes.
