How do you satisfy guests with severe allergies while still creating memorable food experiences? Most caterers focus only on obvious allergens like nuts and shellfish, missing hidden dangers in everyday ingredients. Cross-contamination during prep often causes more reactions than the allergens themselves.
Know the 14 EU-mandatory allergens
You'll need to identify all 14 EU-mandatory allergens for any allergen-free menu. These aren't just obvious ones like nuts and milk - celery and sulfites catch many chefs off guard.
💡 The 14 mandatory allergens:
- Gluten (wheat, rye, barley, oats, spelt, kamut)
- Crustaceans (shrimp, lobster, crab)
- Eggs
- Fish
- Peanuts
- Soy
- Milk (including lactose)
- Tree nuts (almond, hazelnut, walnut, cashew, pecan, Brazil nut, pistachio, macadamia)
- Celery
- Mustard
- Sesame seeds
- Sulfur dioxide and sulfites (>10 mg/kg)
- Lupin
- Mollusks (mussels, oysters, squid)
Track down hidden allergens in ingredients
Hidden allergens cause the most problems. Soy sauce contains wheat gluten, bouillon cubes often have celery, and wine frequently contains sulfites.
⚠️ Watch out:
Always check supplier ingredient lists carefully. "Gluten-free" doesn't mean free from other allergens - many gluten-free products still contain eggs or milk.
Basic ingredients for allergen-free cooking
Build your menu around 'safe' basic ingredients that virtually all guests can eat. These ingredients become your foundation for creative, delicious dishes.
💡 Safe basic ingredients:
- Rice (naturally gluten-free)
- Fresh vegetables (carrot, zucchini, bell pepper, tomato)
- Fresh herbs (parsley, basil, thyme)
- Olive oil (pure, avoid flavored blends)
- Salt and pepper (without additives)
- Fresh meat and fish (no marinades)
- Potatoes (peeled and freshly prepared)
Prevent cross-contamination in the kitchen
Cross-contamination ruins even perfectly allergen-free ingredients. From years of working in professional kitchens, I've seen too many safe dishes contaminated through shared equipment and poor prep sequencing.
- Separate cutting boards: Use different colors for different allergens
- Clean knives: Wash between each ingredient or use dedicated knives
- Separate pans: Cook allergen-free food in clean, unused pans
- Prepare first: Make allergen-free dishes before other menu items
⚠️ Watch out:
Frying oil creates massive cross-contamination risks. Fry breaded fish first, then fries, and those fries now contain gluten.
Menu composition for different diets
Smart allergen-free menus offer at least one safe option for each common allergy. This prevents guests from going hungry or feeling excluded.
💡 Example allergen-free buffet (50 people):
- Main course 1: Grilled chicken with rosemary (salt, pepper, olive oil only)
- Main course 2: Pan-seared salmon with fresh herbs (no butter, olive oil only)
- Side dish 1: Steamed rice (plain, no bouillon)
- Side dish 2: Roasted vegetables (zucchini, bell pepper, carrot)
- Salad: Mixed greens with olive oil and vinegar (dressing served separately)
This menu avoids: gluten, nuts, milk, eggs, soy
Communication with guests
Clear communication prevents dangerous misunderstandings and builds guest confidence. Your entire team must know which dishes contain which allergens.
- Buffet cards: List specific allergens each dish contains
- Separate serving spoons: Prevent allergen spread via shared utensils
- Trained staff: Ensure servers know exact ingredients
- Emergency plan: Keep nearest hospital contact details readily available
Digital registration for overview
Digital systems help you track which ingredients contain which allergens. This reduces mistakes during menu planning and recipe development.
Apps like KitchenNmbrs let you record which of the 14 allergens appear in each ingredient. You'll automatically see all allergens in your final dishes during recipe composition.
How do you create an allergen-free menu? (step by step)
Inventory all allergies of your guests
Ask the organizer about specific allergies and intolerances. Make a list of what you absolutely must avoid and what you preferably avoid.
Choose safe basic ingredients
Select ingredients that are naturally free from most allergens: rice, fresh vegetables, pure meat/fish, olive oil and fresh herbs without additives.
Plan your kitchen logistics
Prepare allergen-free food first, use separate cutting boards and pans, and ensure clear separation to prevent cross-contamination.
Test your recipes beforehand
Try all dishes before the event takes place. Check that the taste is good without the 'forbidden' ingredients and that you've correctly registered all allergens.
Communicate clearly with guests
Create clear cards for the buffet with all allergens per dish. Make sure your serving team knows what's in each dish and train them to answer questions.
✨ Pro tip
Test your allergen-free menu with a 72-hour prep timeline before any major event. This reveals hidden ingredient issues and cross-contamination risks you'll miss during rushed preparation.

Frequently asked questions
How do I prevent cross-contamination at a large buffet?
Use separate serving spoons per dish and place allergen-free options at the buffet's beginning. Maintain adequate spacing between dishes with and without allergens. Replace serving utensils immediately if they touch the wrong dish.
What if a guest has an allergic reaction during my event?
Call emergency services immediately and have the nearest hospital's contact details ready. Keep all ingredient lists available so medical personnel know exactly what the guest consumed.
Are organic products automatically allergen-free?
No, organic certification has nothing to do with allergens. Organic wheat still contains gluten, organic milk still has lactose. Always read ingredient lists regardless of organic status.
Do I need separate menus for each specific allergy?
That's unnecessary and impractical. Create a base menu avoiding most common allergens, then offer 1-2 additional options for specific needs like strict gluten-free or vegan requirements.
