Where eggs hide — read the ingredient, not just the name
Egg is more than "eggs" on a menu. Chefs use whole eggs, yolks, whites and powdered albumin for texture and binding. Egg-derived ingredients include mayonnaise, aioli, hollandaise, custard, meringue, egg wash, batter, and certain processed items like some meatball binders or imitation crab.
Always read descriptions for words like creamy, velouté, en croûte, or glazed — any one can mean egg is present. If a menu marks a dish "contains eggs" or "may contain eggs," treat those labels differently: "contains" is explicit; "may contain" often signals cross-contact risk but not necessarily intentional egg in the recipe.
Commonly surprising dishes and why
- Mayonnaise-based dressings and salads — Potato salad, coleslaw, dressings on composed salads. Ask whether the dressing is mayo or an emulsion with egg yolk (many are).
- Aioli, hollandaise and bearnaise — These are egg-emulsion sauces: swapping them alters the dish significantly. They are not easily removed without changing texture and flavor.
- Carbonara and some pasta dishes — Traditional carbonara uses raw egg yolk stirred into hot pasta to create a silky sauce; asking for it to be omitted usually turns it into a different, less rich dish.
- Tempura, some battered fry items and katsu — Batter often contains egg; some kitchens combine tempura batter with beer or water but still use egg. Fryer cross-contact is common.
- Breads and pastries — Egg wash on bread and pastries is invisible in the ingredient list but common. Also many enriched breads include eggs in the dough.
- Desserts that seem safe: ice cream, mousse, custard and meringue — Ice cream bases sometimes use custard (egg yolks). Mousse and meringue are typically egg-based even when they taste light.
- Processed items — Surimi (imitation crab), some sausages, meatballs and pre-made dressings can use egg as binder or glaze. Ask about brand names when possible.
Exact phrases to say to the server or chef
Say it plainly and include severity. Use these lines word-for-word:
- "I have a severe egg allergy. Can you check whether this dish or any component contains egg, egg yolk, egg white, mayonnaise, aioli, custard, meringue, or an egg wash?"
- "Is the batter or breading made with egg, and do you fry in a shared fryer?"
- "Do you use a commercial brand for this item? What brand is it, so I can check the ingredients?"
- "If the dish normally contains egg, can the kitchen make it without egg and prepare it on clean equipment, or is cross-contact unavoidable?"
- "Please note my allergy on the ticket and confirm the kitchen has seen it."
What a helpful answer sounds like — and what to worry about
Good answers are specific, not vague. Expect phrasing like:
- Good: "That dressing is mayonnaise-based — we can make a vinaigrette instead and I'll mark your ticket so the cook uses a clean bowl and utensils."
- Good: "The carbonara is made with egg yolk; we can't make the same dish without eggs, but we can offer an alternative pasta with tomato sauce."
- Worry: "It should be fine." If the server cannot name the component (yolk, albumin, egg wash) or hasn't checked with the kitchen, it's not helpful.
- Worry: "We don’t have time to change that." That usually means the restaurant lacks the procedures or staff to prevent cross-contact; consider a different choice.
When a server offers to check, ask them to confirm back the specific ingredient name and whether the cook will prepare it on clean equipment — not just that the dish is "egg-free." That level of detail distinguishes a real check from an offhand "no eggs."
How restaurants can adapt — and the trade-offs
Some substitutions are simple: swap mayo for vinaigrette, order sauces on the side, or choose grilled over breaded options. Trade-offs include texture, temperature and flavor: no hollandaise means no silky yolk-based richness; no egg wash on a pastry changes color and shine; omitting egg in a meatball can make it looser.
Smaller kitchens may not have separate fryers, dedicated prep space or the staff to execute strict cross-contact avoidance. Larger chains may have allergen charts but still use shared equipment. The answer is often "it depends" on the restaurant's size, staff training and menu complexity — and on how severe your allergy is.
Quick checklist you can use right now
- Speak up before ordering: use one of the exact sentences above.
- Ask for the ingredient name and whether the kitchen will avoid cross-contact (clean utensils, separate oil or prep area).
- Get a manager if the server is unsure; managers usually have access to supplier info or recipes.
- If the reply is vague or "we think it's fine," pick a simpler dish you can confirm as egg-free.
- When in doubt, choose items with clear, simple ingredients (plain grilled proteins, steamed vegetables, vinaigrette) and ask about preparation.
