Introduction
When you're planning an event for 50+ people, dietary preferences get complicated fast. You have your vegan cousin, your colleague with a peanut allergy, your friend's partner who's kosher, your aunt who's "mostly vegetarian but will eat chicken," and three people asking about gluten-free options.
Managing all this feels overwhelming. But here's the truth: with the right process, it's simple.
This guide walks you through how to ask about dietary preferences correctly, organise responses for your caterer, prioritise allergies vs. preferences, and avoid costly day-of surprises.
Time to read: 8 minutes | Difficulty: Beginner
Why Dietary Preferences Matter
For guests: They feel heard and respected. They're not stressed about not being able to eat. They feel included, not like an afterthought.
For your event: Better photos (happy guests who are eating), smoother service (caterer knows what they're serving each table), no day-of scrambling.
For your caterer: Clear expectations, easier execution, avoidable mistakes.
Step 1: Understand the Types of Dietary Preferences
Allergies (Safety — Non-negotiable)
Priority: Critical. Examples: peanut, shellfish, dairy, egg allergies.
Never compromise. If someone says they have an allergy, treat it as absolute fact. Alert your caterer multiple times.
Religious and Cultural Restrictions (Respect — Important)
Priority: High. Examples: Kosher (no pork or shellfish), Halal (specific preparation required), Hindu (many avoid beef), Buddhist (some are vegetarian).
Respect these completely. Don't try to "work around" them or offer substitutes without checking.
Ethical Restrictions (Accommodation — Important)
Priority: Medium. Examples: Vegetarian, Vegan, Pescatarian.
Make deliberate menu choices. Offer equivalent quality mains — not a sad salad as the only vegan option.
Lifestyle Preferences (Acknowledge)
Priority: Low. Examples: Paleo, Low-carb, Keto, Dairy-free by choice.
Do your best, but don't stress. These are lifestyle choices, not safety or ethics. A note to the caterer is sufficient.
Step 2: Ask the Right Way
The Wrong Way
❌ "Do you have any dietary restrictions?"
Why it fails: Vague question → vague answers. Guests under-report (they think you're only asking about serious allergies). You get responses like "I don't eat much red meat" — not actionable.
The Right Way
✅ "Please select any dietary preferences below. We want to make sure you have delicious food to eat!"
Then offer specific checkboxes:
- Vegetarian (no meat, ok with dairy/eggs)
- Vegan (no meat, dairy, or eggs)
- Gluten-free (no wheat, barley, rye)
- Pescatarian (no meat, ok with fish)
- Kosher
- Halal
- None of the above / No restrictions
Plus a text field: "Other allergies or preferences (optional)"
Why it works: Specific options yield specific answers. No ambiguity. You know exactly how many vegans, vegetarians, and gluten-free guests you have.
Step 3: Ask for Details on Allergies
If someone notes an allergy, you need details to keep them safe.
Follow-up questions to ask:
- What is the allergen? (e.g. peanuts, shellfish, dairy)
- Is this a severe allergy (life-threatening) or mild intolerance?
- Any other context? (e.g. ok with tree nuts but not peanuts?)
Why this matters:
- Severe allergy → caterer must prep separately, avoid cross-contamination entirely
- Mild intolerance → caterer can note it but may not need separate prep
- Specific details → prevents miscommunications like "I thought peanuts were ok!"
Step 4: Ask for Plus-One Dietary Preferences
This is critical and often missed.
When a guest confirms they're bringing a plus-one, ask:
- Plus-one name
- Dietary preferences (same checkboxes as main guest)
- Any allergies
Without this, you're planning for the wrong number of vegan/gluten-free meals and may not know about a life-threatening allergy.
💡 Using Pixova: The RSVP form automatically shows the plus-one dietary form as soon as a guest indicates they're bringing a companion — no follow-up needed.
Step 5: Organise Responses for Your Caterer
Once RSVPs are finalised, aggregate by category and create a dietary summary:
DIETARY SUMMARY — [Event Name]
Total Guests: 170 (142 confirmed + 28 plus-ones)
By Category: Vegan 8 · Vegetarian 12 · Gluten-free 5 · Pescatarian 4 · Kosher 2 · Halal 1 · No restrictions 138
ALLERGIES (CRITICAL — SEPARATE PREP):
- Peanut: Sarah Johnson (Table 3), Michael Chen (Table 5)
- Shellfish: Jennifer Lee (Table 2), David Smith (Table 8)
- Dairy: Tom Bradley (Table 4)
Caterer Communication Timeline
- 2 weeks before: Email dietary summary, schedule a call to review allergies specifically
- 1 week before: Ask caterer to confirm allergy prep approach in writing
- 48 hours before: Final confirmation of allergy handling
Step 6: Prioritise and Communicate Clearly
Priority Hierarchy
- Allergies (safety) — MUST accommodate, confirm multiple times
- Religious restrictions (respect) — MUST accommodate
- Ethical restrictions (vegan/vegetarian) — SHOULD accommodate, offer quality options
- Lifestyle preferences (paleo, keto) — NICE to accommodate, don't stress
For Allergy Communication
Be explicit and direct with your caterer:
"We have 2 guests with severe peanut allergies and 3 with shellfish allergies. Please confirm your prep protocols for these. I need written confirmation you've received this."
For Ethical Restrictions
"We have 8 vegan and 12 vegetarian guests. Please confirm: what is the vegan main? It should be equivalent quality to the standard meal — not a salad-only option."
Common Mistakes to Avoid
Offering only salad for vegan guests. Vegan guests feel excluded and under-served. Offer an actual vegan main that's as good as the standard meal — pasta primavera, roasted vegetables with a protein, or a plant-based entrée.
Not asking about plus-one dietary preferences. Your guest's companion can't eat, you have extra vegan meals but needed pescatarian. Fix: include plus-one dietary in your RSVP form — never assume.
Treating allergies like preferences. Caterer doesn't take it seriously, guest with a nut allergy gets pesto. Fix: flag allergies separately, call the caterer, confirm multiple times.
Not confirming with caterer. You think they know about 8 vegans, they prepared 2 vegan mains. Fix: send written dietary summary and get written confirmation they'll prepare accordingly.
Ignoring open-ended "other" responses. Guest writes "paleo, no sugar, low-carb, dairy-free" and you have no idea what to prepare. Fix: follow up: "I see you wrote [preference] — what does this mean for your meal? Should we prepare X?"
Dietary Preference Collection: What to Ask
Here is a complete RSVP dietary section structure:
Step 1 — Dietary preferences (checkboxes: Vegetarian, Vegan, Gluten-free, Pescatarian, Kosher, Halal, None of the above)
Step 2 — Allergies (Yes/No; if Yes: allergen name and severity — severe vs. mild)
Step 3 — Other notes (optional free text)
Step 4 — Plus-one dietary (if they indicated a plus-one: same checkboxes + allergy field)
Dietary Management Checklist
- Ask about dietary preferences clearly (checkboxes, not open-ended)
- Ask about plus-one dietary (don't assume)
- Ask for allergy details (what allergen? severe or mild?)
- Aggregate responses by category
- Create dietary summary for caterer
- Send to caterer 2 weeks before
- Call caterer to confirm allergies specifically
- Verify with caterer 1 week before
- Final allergy confirmation 48 hours before event
- Brief your team on dietary diversity
Final Thoughts
Dietary preferences aren't a burden — they're an opportunity. When you ask the right questions, get organised, and communicate clearly with your caterer, everything flows smoothly. Your guests feel seen and cared for. Your caterer executes flawlessly. Your photos look great because everyone's eating and happy.
