What should you actually tell a private chef about dietary restrictions?
Tell the chef five things per affected guest: the first name, the exact substance, whether it is an allergy, an intolerance or a preference, what happens if they eat it, and whether traces matter. Five short lines beat five paragraphs of context, and European kitchens are built around exactly that structure. Regulation (EU) No 1169/2011, the food information law behind every Italian kitchen, defines 14 declarable allergens: cereals containing gluten, crustaceans, eggs, fish, peanuts, soy, milk, tree nuts, celery, mustard, sesame, sulphites, lupin and molluscs. American guests are often caught out, because the United States declares nine: celery, mustard, lupin and sulphites are European additions a traveller may never think to mention. And name the substance, not the dish. 'No pesto' tells a chef almost nothing, because pesto alla genovese, the Ligurian basil sauce pounded with garlic and oil, hides three separate candidates: pine nuts, Parmigiano Reggiano and pecorino. 'No tree nuts, pine nuts included' tells him which of the three has to go and lets him keep the sauce.
Dietary restrictions vs preferences: why the wording changes the kitchen
A restriction is something a guest's body or belief system does not allow, while a preference is something a guest would rather not eat. Both belong in the brief, but they trigger different behaviour at the stove, so label them honestly. Search for a dietary restrictions list online and you will find dozens, most of them pouring both categories into one undifferentiated column. A chef cannot. A shellfish allergy means dedicated boards, a separate pan and a plate that never crosses a prawn, while a dislike of shellfish means the chef simply plates something else. Upgrade a preference to an allergy because you think it will be taken more seriously and you spend the chef's attention in the wrong place, which on a table of 10 guests is finite. The typical dietary restrictions we see fall into four groups: medical allergies, digestive intolerances such as lactose or FODMAP sensitivity, religious and ethical rules including vegetarian, vegan, halal and kosher, and personal dislikes. When a religious requirement goes beyond swapping an ingredient, flag it early: our guide to kosher dining in Tuscany explains why sourcing and supervision, not the recipe, are the real constraint.
When should you tell the chef, and how late is too late?
Tell the chef the moment you request the quote, not after you have chosen a menu, because restrictions shape the menu and rebuilding one costs everybody a round of emails. Average booking lead time across our network is 7 to 14 days in peak season, June to September. Inside that window sit three checkpoints. At enquiry, the restrictions decide which dishes get proposed at all. Roughly 7 to 10 days out the menu locks, the last comfortable moment to add something new without reshaping courses. Then 24 to 48 hours before service the chef shops, and once he has bought fish for 8 guests a late 'actually my sister does not eat fish' costs a second trip to a market that only opens in the morning. If you are still deciding when to book, our note on how far in advance to book a private chef sets out the seasonal windows. The short version for anyone eyeing a farmhouse near Siena: August dates for private chefs across Tuscany are usually gone 3 to 4 weeks ahead, and a menu carrying three restrictions needs more of that runway, not less.
What if a restriction surfaces after the menu is locked?
Say it anyway, immediately, and in writing, because a chef would far rather rework a course at eight in the morning than discover the problem when a plate goes down. What is possible depends on the checkpoint. Before the shop, almost anything changes at no extra cost. After the shop, the chef can usually substitute one course, because a professional shopping list carries slack: extra vegetables, a spare protein, more base ingredients than the recipe needs. On the day itself, in a villa 30 minutes from the nearest alimentari, one guest may simply eat a plainer version of the menu. There is one case where 'we will manage' is the wrong answer: a severe allergy disclosed on the day. If a guest carries an adrenaline auto-injector the chef needs to know before he plans his mise en place, because the sequencing of the whole service changes. Told at the table, the safest thing he can do is cook that guest something deliberately plain, and nobody wants that to be the memory.

How much detail is useful, and how much is just noise?
Useful detail is anything that changes a decision in the kitchen. Diagnosis names, family history and the story of how the allergy was discovered are noise. Reaction severity, trace tolerance, safe substitutes and a short list of foods the guest enjoys are gold. The trace question is the one guests skip and chefs most need answered. Two people can both say 'peanut allergy' and mean different things: one avoids peanuts on the plate, the other cannot be in a kitchen where peanut oil has been used that day. That distinction decides whether the chef omits an ingredient or rebuilds the prep sequence, brings separate equipment and cooks the safe plates first. Adding a line of positives is worth more than it looks. 'No dairy' produces a careful, slightly defensive menu. 'No dairy, loves grilled fish, happy with anything from the sea' produces a chef who builds that guest a better dinner than the one he was already planning. Personal chef packages for allergies are not a separate product we sell, because a restriction is an input to the menu rather than an add-on.
- List each guest by first name, then the exact substance to avoid. Never write 'one guest has allergies' without saying which guest and to what.
- Label the severity in a single word: allergy, intolerance or preference. Add 'anaphylactic' where it applies, because that word changes the whole service.
- Answer the trace question outright: does the guest react to cross-contact, or only to the ingredient on the plate?
- Name two or three foods the guest genuinely enjoys, so the chef designs towards something instead of around a hole.
- Flag children separately with their ages, because portion size and spice tolerance shape a menu as much as an allergy does.
- Mention any medication timing that affects the meal, such as insulin or enzyme supplements, so the chef can pace the courses.
- Send the list once, in the booking notes, then re-confirm the identical list 48 hours before service while the chef is writing his shopping list.
How do private chefs prevent cross-contamination in a home kitchen?
A holiday rental kitchen has one oven, one hob, one colander and whatever knives the owner left in the drawer, which is exactly why chefs who work in private homes carry their own equipment. The working method is sequencing. The chef cooks the safe dishes first, on clean surfaces, before the allergen is ever opened. He plates them, covers them, and moves them out of the working zone before the rest of the menu begins. In a kitchen with one hob that is the only reliable way to keep a shellfish-safe plate separate from a shellfish sauce, and it is why an allergy declared in advance costs an hour of planning instead of a panic. Equipment is the second layer, and our chefs travel with their own boards, knives and pans, which matters when the villa's wooden board has absorbed garlic and anchovy for a decade. Our note on what a private chef actually needs in your kitchen covers the equipment side, and our guide to rentals that can host a chef explains which layouts make separation easy. Two metres of counter stops being a luxury the moment two menus are running.
Cross-contact vs cross-contamination, and the four routes it travels
Chefs use two words that sound interchangeable and are not. Cross-contamination is the transfer of bacteria, the raw-chicken-to-salad problem that HACCP food safety plans exist to prevent. Cross-contact is the transfer of an allergen protein, and unlike bacteria it is not destroyed by heat: getting a pan screaming hot does nothing to a peanut protein sitting in it. Look up the four types of cross contamination and you get the food-safety version: food to food, equipment to food, people to food, environment to food. The allergen version travels the same four routes. Food to food is a serving spoon shared between two dishes. Equipment to food is the colander that drained wheat pasta an hour earlier. People to food is a hand that opened a bag of flour and touched a plate. Environment to food is airborne flour during a pasta class, which is why we ask coeliac guests to tell us before a class, not halfway through. Awareness of food allergies in food service has risen sharply in Italy since 2015, but a rented villa is not a regulated kitchen, so the chef brings the protocol with him.
Which Italian ingredients quietly contain allergens?
Italian cooking hides allergens in places no menu warns you about, because the ingredients are traditional rather than declared. Four deserve memorising. Pecorino Romano DOP, the hard salted sheep's milk cheese grated over carbonara and cacio e pepe, is made with animal rennet, which makes it both dairy and not vegetarian, and ethical vegetarians are served it constantly without knowing. Colatura di alici, the amber anchovy liquid produced at Cetara on the Amalfi Coast and descended from Roman garum, seasons pasta and vegetable dishes where no fish is visible, so a fish allergy must be declared as fish rather than as 'no seafood main course'. Bottarga, the cured grey mullet or tuna roe grated over spaghetti in Sardinia and Sicily, is fish in a form that looks like a spice, and lardo, the herb-cured pork back fat aged in marble basins at Colonnata in northern Tuscany, arrives on warm crostini looking like cheese. Then the assemblies. Vitello tonnato, the Piedmontese cold veal under a tuna and caper sauce, is a fish dish wearing a meat name. Fresh tagliatelle is eggs, while pici, the thick hand-rolled Tuscan spaghetti our chefs teach across our Tuscan chef network, usually is not.
Eating gluten-free in Italy without living on salad
Italy is one of the easier countries in Europe for a coeliac traveller, which surprises people who assume a pasta culture would be hostile. Coeliac disease, an autoimmune reaction to gluten affecting roughly 1% of the European population, is screened for in Italian schools, and Associazione Italiana Celiachia runs a national certification scheme for restaurants and producers, so awareness inside professional kitchens is high. For a private dinner the picture is better still, because whole categories of the repertoire contain no gluten by tradition rather than by substitution: risotto, polenta, farinata, most braises, grilled fish and the entire southern vegetable canon. A menu without wheat need not be a sequence of compromises around a sad replacement pasta. The real constraint is the shared kitchen rather than the recipe. Flour is airborne, and a villa where somebody made pizza yesterday still has flour on the shelves. Declare coeliac disease as a medical condition rather than a preference, and the chef will sequence your plates first and bring his own pans.

How do you feed a mixed table without cooking three separate dinners?
You do not cook three dinners. You cook one menu with divergent finishes, the technique that makes a mixed table work and the best argument for a private chef when the group is complicated. Each course is built on a base everyone can eat, then finished differently on the plate. A vegetable antipasto goes out plain for the vegan and with lardo for everybody else, and a pasta course carries the same sauce on two pastas, one wheat and one made without gluten. Dessert is the course chefs most often design around the strictest guest, because a sorbet or a flourless chocolate dessert satisfies all 10 guests without announcing itself as the special plate. That matters more than the food: nobody on holiday wants to be the person visibly eating something else. Restrictions carry no surcharge either. A Taste of Italy menu, our five-course mid tier, runs roughly €120 per person for 6 guests in Tuscany and around €100 per head at 10 guests, whether or not three of them have allergies. The four-course Essential tier sits near €95 per person at 6 guests, the Luxury tier of six or more courses near €180. What restrictions change is planning time, not the invoice.
Does a multi-day chef handle restrictions differently from a one-night dinner?
Yes, mostly in your favour. A multi-day booking, where the chef accompanies your group for the whole stay and cooks the meals you select day by day, gives him what a single dinner cannot: a second chance to shop. On a one-night booking the shopping happens once, 24 to 48 hours ahead. On a multi-day stay the chef goes to market most mornings, so a restriction that surfaces at breakfast on day one is absorbed by lunch on day two. Groups typically pick two or three dinners plus a long lunch across a week rather than three meals a day, and that rhythm leaves room to adjust. Cost depends on where the chef sleeps, in three configurations. If your villa has a spare room and the chef stays on the property, the daily rate is lowest because you absorb the accommodation. If the chef lives locally and commutes in, common in Chianti, the Amalfi Coast and Lake Como, there is no lodging line at all. If neither applies, he books a room nearby and the quote line-items that surcharge openly. Multi-day quotes are built upwards from the per-meal cost, so they are custom rather than a single per-person rate, and daily market shopping is included in all three.
Why this matters for your Italian holiday
Every guide to Italy tells you where to eat. Almost none tells you how to eat well when your table holds a coeliac, a vegetarian and a nine-year-old who will only consider pasta. That is where most holiday meals quietly go wrong, and not because Italian kitchens are inflexible: a restaurant running 60 covers cannot rebuild a dish from the base upwards for one person, so a guest with a real allergy orders defensively and eats less than everyone else. A private chef inverts that. The menu is written after he knows who is sitting down, so the restriction stops being a subtraction and becomes part of the brief. We watched a nut-allergic teenager eat five courses in a farmhouse outside Montalcino without a single moment of negotiation, and watched her parents relax for the first time in a fortnight. That is the actual product. Chef On Demand holds a 4.7/5 Trustpilot rating built on 800+ guests served since 2025, and plenty of those bookings arrived with a paragraph of restrictions attached. If you are mapping where to stay, browse the wider private chef network across Italy or book a Tuscany private chef experience and send your list with the enquiry. Write it as a list, send it early, then sit down at a table in Florence or in a garden above the vines and let somebody else worry about the pans.
