Egg allergy — what to watch for, and how to cook around it
In one paragraph
Egg allergy involves an immune reaction to proteins in egg whites, egg yolks, or both. Reactions range from mild to anaphylactic. Eggs hide in fresh pasta, many baked goods, mayonnaise, custards, certain ice creams, Caesar dressing, and as a glaze on pastries. For cooking, flax eggs and commercial replacers substitute in most baked goods.
Why it matters
Egg allergy is common enough that most kitchens have accidentally served eggs to someone who can't have them. The fix is label-reading and substitution, not elaborate rework. Eggs appear in far more prepared foods than hosts expect; the bread you bought, the pasta you made fresh, the glaze on the croissants. Ask the guest for their severity level and adjust the cross-contact protocol accordingly.
For the guest: script
'I'm allergic to eggs — [severity]. No eggs in the dish, and watch for hidden eggs in pasta, mayo, baked goods, and glazes. For me [cross-contact matters / doesn't]. I'm happy to bring a dessert I can eat; desserts are the usual landmine.'
For the host or business
Read labels on pasta, bread, and dressings — eggs are often there. Skip the Caesar, the mayo-based coleslaw, the fresh pasta. For a baked main, use a commercial egg replacer or ground flax (1 tbsp flax + 3 tbsp water = 1 egg). Fruit or sorbet is the safer dessert. Ask the guest which brands they trust.
Frequently asked questions
- Are eggs in vaccines a problem for egg-allergic people?
- Most vaccines (including modern flu shots) can be safely given to egg-allergic people. Talk to your allergist; the old guidance has been updated. This page is about kitchens, not clinics — but the overlap comes up often.
- Can egg-allergic people eat baked goods where the eggs are cooked?
- Some people with mild egg allergy can tolerate baked eggs (in cake, muffins), where heat has denatured the proteins. For others it still triggers a reaction. Don't guess — ask the guest whether 'baked eggs' are safe for them specifically.
- What's the best egg substitute for baking?
- For binding: ground flax or chia (1 tbsp + 3 tbsp water). For leavening: commercial replacers like Bob's Red Mill. For moisture: mashed banana or applesauce. Each has trade-offs; flax eggs work best in dense baked goods, less well in cakes.
