Fermentation runs through the work — kombuchas, vinegars, and no-waste preparations that turn vegetable offcuts into sugar, salt, or a petit-patisserie at the end of the meal. Inside the monastery's stone walls, that's the whole of it.

The delicious details

Osteria del Vicario occupies the stone-walled rooms of a 12th-century monastery in Certaldo Alto, the medieval hilltop quarter of this Tuscan town. Chef Eleonora Rizzo and Erik Regini run both the kitchen and the adjoining bed and breakfast, a family business with just eight to ten seats and a fully plant-based tasting menu that changes monthly.

The kitchen is contemporary and globally influenced, drawing on flavours from across culinary traditions, from Sichuan pepper and tamarind to Arab-influenced preparations alongside fresh pasta and other European techniques. Every course is built on vegetables, fruits, grains, and legumes, sourced largely from the restaurant's own gardens and local growers. Meals are served on a terrace overlooking the Tuscan hills and the towers of San Gimignano, or in the interior rooms of the former monastery.

A word from…
The people behind the plates

Osteria del Vicario is a plant-based restaurant and B&B inside a medieval monastery of 1100, at Certaldo Alto, a medieval hamlet next to Florence and Siena. It's a family business, only two people running the show, only 8–10 seats with a monthly changed tasting menu, completely plant-based. Everything comes from the kitchen: pasta, breads, desserts, all home-made. Fermentation runs through the work — kombuchas, vinegars, and no-waste preparations that turn vegetable offcuts into sugar, salt, or a petit-patisserie at the end of the meal. Fruits and vegetables come from local growers just up the road, and what's in season shapes the menu. Inside the monastery's stone walls, that's the whole of it.

Menu
What's on the table, and what's left off

All menus are plant-based with a monthly changed tasting format. The kitchen prepares everything in-house, from fresh pasta and fermented condiments to desserts, using whole ingredients and fermentation-derived alternatives to refined sugar. Seasonal produce from the restaurant's own gardens and nearby growers shapes each month's menu.

All our menus are plant-based, from the B&B guests' breakfasts to our monthly changed tasting menu. Everything is home-made. We also work a lot with fermentations such as home-made kombucha, shoyu, and other things.

The tasting menu moves freely across culinary traditions: a course might pair BBQ watermelon with Sichuan pepper, follow with fresh pasta, or close with a mushroom kebab with Greek yogurt and tamarind sauce. Seasonal produce from the restaurant's own gardens and nearby growers shapes each month's menu, and virtually everything is prepared in house, from sauces and fermented condiments to breads and desserts. The kitchen works with whole ingredients throughout, using fermentation-derived alternatives to refined sugar and preparing stocks, dressings, and preserves from scratch. The tasting menu is structured with attention to protein distribution and digestibility, with fermented elements placed at the start of the tasting and richer components later. Erik selects the wine pairings from small family producers in Tuscany and beyond.

How this restaurant rates
4 - Recognised

Roughly 90% of ingredients come directly from named local producers, including Barbara and Paolo for fruits and vegetables, Ronzii e Piccole Erbe for herbs, and small family wineries like Podere Pellicciano for the wine programme, alongside produce from the restaurant's own gardens. The menu changes monthly, following seasonal availability.

Waste is addressed through deliberate circular practices: the kitchen works each ingredient to its fullest, roasting fruit seeds, dehydrating skins, and using fermentation to transform what might otherwise be discarded into kombucha, vinegar, and vegetable-based seasonings. Cloth napkins, returnable supplier packaging, no single-use tableware, and green energy round out the approach.

The restaurant maintains an ongoing commitment to local animal welfare through its support of Amici a 4 zampe, a cat and dog rescue shelter near Certaldo. As a fully plant-based kitchen listed in the We're Smart Green Guide, vegetables, fruits, grains, and legumes are the sole foundation of every course.

Approximately 90% of ingredients are sourced directly from named local suppliers, including Barbara & Paolo for produce and Podere Pellicciano for wines.

Approximately 90% of ingredients are sourced directly from named local suppliers across multiple categories: Barbara & Paolo in Empoli for fruits and vegetables, Ronzii e Piccole Erbe for herbs, and Podere Pellicciano, SelvaticaLab, and Feral for wines and alcohol-free beverages. The restaurant's own gardens supply additional produce seasonally.

Non-local items account for roughly 10% of ingredients: Asian sauces, Asian peppers, and tahini. The restaurant reports 80–100% of providers are organic certified, though no specific named certification is documented. Prior We're Smart Green Guide listing corroborated own-garden production and regional Tuscan sourcing.

Strongest sourceRestaurant submission

Fruit and vegetable sourcing is 100% seasonal; the tasting menu changes monthly, corroborated by the We're Smart Green Guide.

The restaurant's tagline is 'Stagionale Vegetale' (Seasonal Vegetable), making seasonality a founding principle. Fruit and vegetable sourcing is 100% seasonal in the tasting menu, up from the previously reported 80–100% range.

Monthly rotation of the tasting menu exceeds the threshold for consistent seasonal engagement. The We're Smart Green Guide confirms this seasonal practice, and the restaurant offers its Instagram menu archive as corroboration.

The kitchen achieves zero food waste through fermentation and full-ingredient utilization; packaging practices include cloth napkins, returnable glass, no single-use tableware, and green energy.

Food waste reduction is achieved through deliberate circular practices: fruit seeds are roasted; skins and zest are used for infusions, dehydrated, or repurposed; fermentation transforms waste into kombucha, vinegar, and vegetable-based salt and sugar. The restaurant reports effectively zero food waste as a result.

Packaging practices span multiple categories: avoidance of plastic, bulk drinks, no single-use tableware (straws, cutlery, bags), no small disposable containers (butter, salt, pepper, sugar, sauce sachets), cloth napkins, and returnable packaging (glass for drinks, transport boxes for suppliers). Green energy rounds out the approach.

Strongest sourceRestaurant submission

100% plant-based kitchen; this dimension does not apply to fully plant-based restaurants.

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.
