Catering an office lunch around dietary restrictions

The approach in one paragraph

Collect dietary needs in a structured form, not a free-text reply-all. Design the shared menu so the vegetarian main is also vegan and gluten-free, the meat is halal-sourced, nuts are left out entirely, and sauces sit on the side. That base covers most of the room. Then order named, sealed meals only for the few people whose needs the base menu cannot meet safely, such as a guest with celiac disease or a severe allergy. Label everything with ingredients and Canada's priority allergens, and set the special meals aside before the line opens.

Done this way, an office of 40 typically needs two to four individual meals rather than fifteen, the food looks like one lunch rather than a main table and a "dietary" corner, and the office manager is not fielding questions at 12:05.

Step 1: collect needs in a form that caterers can use

"Any dietary restrictions?" in an email gets you answers like "no carbs this month", "mild lactose thing" and silence from the one person with an anaphylactic allergy. A short form with fixed choices gives the caterer what it needs and separates medical needs from preferences.

Keep the form to five questions: name, dietary pattern (none, vegetarian, vegan, halal, kosher, other), allergies or intolerances from a list, how severe (preference, intolerance, allergy, allergy requiring an epinephrine auto-injector) and an optional note. Store answers with the minimum people who need them; allergy information is personal health information and should be handled that way.

For a recurring team, collect once and ask people to update it each quarter. For a one-off event with external guests, add the dietary question to the RSVP and set the deadline a day before the caterer's final count.

Step 2: design one base menu that covers most of the room

Here is how the needs of a typical 40-person Toronto office might look, and how a well-built base menu handles them. The counts are an illustration, not a survey.

That is three individual meals out of 40. The design choices doing the work:

• Make the vegetarian main vegan and gluten-free. A chickpea and spinach curry with rice, or roasted cauliflower with tahini and lentils, covers four needs at once and is popular with meat-eaters too.
• Use halal-sourced meat for the whole order. Most people will not notice, and Muslim colleagues eat from the same trays. Ask the caterer how the meat is sourced and whether the kitchen is certified; the difference matters to many people and is explained in our halal catering guide.
• Leave nuts and sesame out of the whole order when anyone has a severe allergy. Pesto, dukkah, satay and some desserts are the usual culprits.
• Keep sauces, cheese and croutons on the side. It turns one salad into a vegan, dairy-free and gluten-free salad.
• Serve bread separately rather than in sandwiches, or offer a rice bowl alongside wraps.

Step 3: label every item properly

Good labels answer the question before it is asked. Each dish on a buffet needs a card, and each individual box needs a sticker, showing the dish name, short dietary codes, and the priority allergens it contains.

Health Canada lists these priority food allergens: eggs, milk, mustard, peanuts, crustaceans and molluscs, fish, sesame seeds, soy, sulphites, tree nuts, and wheat and triticale. Gluten sources such as barley, rye and oats that are not certified gluten-free matter for people with celiac disease too. A label should name any of these that are in the dish, not rely on "may contain allergens".

The kitchen note is honest and important. Unless a caterer has a dedicated gluten-free area, "gluten-free" on a label means gluten-free ingredients prepared in a shared kitchen, which is fine for most people avoiding gluten and not enough for some people with celiac disease. Canada's Food and Drug Regulations restrict gluten-free claims to foods that meet Health Canada's gluten-free requirements, which is why a careful caterer describes both the ingredients and the kitchen rather than printing "GF" and stopping there. See our dietary catering overview for how we word ours.

Step 4: serve it so the right meal reaches the right person

Most dietary mix-ups happen in the ten minutes after the food lands, not in the kitchen. A few habits prevent them:

1. Set individual meals aside before the buffet opens, on a separate table or in the meeting room fridge with names facing out. Tell those guests where they are.
2. Put the base-menu dietary dishes first in the line. Vegan and gluten-free guests get their share before the vegetarian main is half gone.
3. One utensil per dish, and no sharing. A spoon that moves from the butter chicken to the dal is how a vegan dish stops being vegan.
4. Keep labels with the dishes when trays are refilled or moved.
5. Do not decant sealed meals onto platters to make the table look fuller.
6. Clear within two hours. Food safety guidance limits food out of temperature control to two hours; after that, leftovers should go, not into the kitchen fridge for tomorrow.

For internal lunches, boxed lunches make this simplest, since every box carries a name and a label. Platters and hot buffets work well too once the individual meals are separated. Our boxed lunches vs platters comparison helps you choose.

Hidden ingredients that catch people out

• Vegan: honey in dressings, ghee in South Asian dishes, fish sauce in Southeast Asian dishes, gelatin in desserts, butter brushed on flatbread, egg wash on pastry.
• Halal: wine or beer in sauces and braises, vanilla extract in some desserts, gelatin from non-halal sources, bacon bits on salads.
• Gluten-free: soy sauce (use tamari), malt vinegar, stock bases, spice blends with fillers, oats that are not certified gluten-free, fryer oil shared with breaded items.
• Nut allergy: pesto, romesco, muhammara, dukkah, praline, almond flour in "gluten-free" baking, nut oils in dressings.
• Dairy-free: butter finishing on vegetables, yogurt in marinades, cream in soups that look clear.

A caterer used to mixed offices will know these; ask to see the ingredient list for any dish you are unsure of.

Questions to ask your caterer before the first order

Ask these before you commit, and ask for the answers in writing:

• How is the halal meat sourced, and is the kitchen itself certified by any body?
• Do you have a dedicated gluten-free area or equipment, or is it a shared kitchen?
• Can you make the whole order nut-free and sesame-free?
• Are individual dietary meals sealed and labelled with the guest's name?
• Do labels list priority allergens by name?
• Can you supply a kosher meal from a certified supplier when needed?
• What is the cut-off for adding a dietary meal after the order is placed?

We answer all of these on request, and our halal, plant-based and gluten-free pages set out what we can and cannot promise. To plan a lunch around your team's actual list, use the enquiry form.
