The delicious details

Het Kook Atelier op Oost is the restaurant of a boutique farmstead on Texel, where chef Joram Timmerman and partner Valerie Jongeneel have built a kitchen entirely around what the island provides. The tasting menu, titled Served by Nature, changes five times a year and adjusts daily according to what the garden, the polders, and the Wadden Sea yield.

The setting is an authentic Texel stolpboerderij surrounded by an edible garden of herbs, flowers, salt-tolerant vegetables, and a small orchard. Guests sit around an open kitchen at the chef's table, with views across the dike landscape. A botanical pairing of house-made kombucha, kefir, and herbal infusions offers a considered non-alcoholic alternative to the wine list of natural and biodynamic wines.

The kitchen works from a six-hectare permaculture plot and a 3,000 square metre edible garden at the property, supplemented by named Texel producers: Boer Jens for beef, raw milk, and lamb, and the Groentehelden collective for vegetables and sea herbs. Fish and shellfish arrive from the Wadden Sea and Zeeland, sourced through the NorthSeaChefs network.

How this restaurant rates
4 - Recognised

Local sourcing is deeply embedded: the restaurant cultivates a six-hectare permaculture garden and 3,000 square metre edible plot, supplemented by named island producers including Boer Jens for livestock and the Groentehelden collective for vegetables and sea herbs. Seasonal cooking follows naturally from this model, with the menu rotating five times annually and adjusting daily to what the garden and foragers bring in.

Circular practices are well developed, with head-to-tail cooking, fixed tasting menus to prevent waste, and systematic conversion of byproducts into fermented beverages, vinegars, and biodegradable cosmetics. Animal products are sourced responsibly, with named local suppliers for meat and dairy, and fish procured through the NorthSeaChefs network, which promotes lesser-known species and bycatch.

The menu is led by vegetables and wild plants, following the Dutch Cuisine 80-20 principle. Het Kook Atelier op Oost holds a We're Smart Green Guide Top 100 listing and a Michelin Green Star, and is recognised by Dutch Cuisine.

Six-hectare permaculture garden and named island suppliers (Boer Jens, Groentehelden) provide all vegetables, seafood, and animal products.

The restaurant operates a six-hectare permaculture garden (De Waelde tuin) with historic orchard and native plants, plus a 3,000 square metre edible garden at the property growing vegetables, herbs, fruits, and cresses. Named island-based suppliers include Boer Jens (East Texel) for beef, raw milk, eggs, and lamb, and the Groentehelden collective for vegetables and sea herbs. Foraged wild herbs from the surrounding landscape supplement cultivated produce.

The restaurant participates in the NorthSeaChefs network for fish and shellfish sourcing from the Wadden Sea and Zeeland, favouring lesser-known species and responsible use. Independently validated by We're Smart Green Guide Top 100 listing and Michelin Green Star.

Menu rotates five times yearly and adjusts daily with garden yields and foraged plants; fermentation extends seasonal availability.

The tasting menu rotates five times annually to reflect seasonal shifts, adjusting daily based on what the garden, foragers, and suppliers provide. The restaurant's own gardens follow no-dig permaculture and lunar cycles, producing inherently seasonal yields.

The kitchen forages wild herbs, flowers, and salt-tolerant plants according to their natural availability. Fermentation and preservation extend the seasonal harvest across the year, enabling off-season use of peak ingredients. The stated philosophy is 'everything has its time, its sequence, its moment'. Validated by Michelin Green Star and We're Smart Top 100.

Strongest sourceRestaurant submission

Head-to-tail cooking and fixed-menu format prevent waste; byproducts become kombucha, vinegars, and fermented preparations.

Head-to-tail and head-to-bone cooking is a stated principle. Fixed tasting menus (no à la carte) are explicitly designed to prevent food waste and enable precise ingredient use.

Residual streams are treated as ingredient streams: vegetable and herb offcuts are converted into kombucha, kefir, syrups, vinegars, and vegan biodegradable cosmetics. Fermentation and preservation extend ingredient lifespan. Rainwater is collected for the garden and no plastic disposables are used.

Strongest sourceRestaurant submission

Boer Jens supplies beef and lamb (head-to-tail use); fish through NorthSeaChefs network promoting lesser-known species.

Named local supplier Boer Jens (East Texel) provides beef, raw milk, eggs, and lamb from dual-purpose cows and Texel sheep. Meat appears sparingly, a few times per year, with head-to-tail use. A fully vegetarian menu is available as an alternative.

Fish and shellfish are sourced from the Wadden Sea and Zeeland through the NorthSeaChefs network, which promotes responsible use of lesser-known species and bycatch, avoiding overfished stocks. The restaurant follows the Dutch Cuisine 80-20 principle, placing vegetables at the centre.

Strongest sourceRestaurant submission

Shares harvests with local gardeners and connects guests to island farmers; Slow Food Professionals member.

The restaurant shares harvests with neighbourhood home gardeners and provides guests with a list connecting them to local farmers and growers. Slow Food Professionals membership indicates commitment to fair food systems, and the establishment welcomes collaborations on sustainability projects.

Strongest sourceRestaurant submission

The restaurant is listed in the We're Smart Green Guide Top 100 (number 76, 2025), the strongest independent validation of vegetable-led dining.

How we score
The My Treats impact scale

Every restaurant is assessed against SEERO, our six-dimension sustainability framework — covering sourcing, seasonality, waste, animal products, social impact, and plant-forward cooking. Each finding is weighted by how strongly it is corroborated. The combined result is translated into a planet rating from 1 to 5.

The five levels

SEERO is an acronym for Starting, Engaged, Endorsed, Recognised, Outstanding:

Starting First verified signals of sustainable practice.
Engaged Credible practice across two dimensions.
Endorsed Meaningful practice across three or more dimensions.
Recognised Strong practice across four or more dimensions, with independent corroboration.
This place
Outstanding Top-tier practice, confirmed by recognised third-party audit.

How a level is reached. Each level needs two things together: a minimum number of dimensions covered, and a minimum overall strength of evidence across them. A dimension only counts once its evidence is specific and substantiated — a passing mention doesn't qualify. Meeting only one of the two keeps a restaurant a level lower.

Ratings of four or five planets require human validation and, at the top tier, an external audit. Scores are based on publicly available evidence and restaurant submissions at the time of assessment.
