Baby has an egg allergy: what to feed and what to avoid

Almost everything written about babies and egg is about how to introduce it. This page is for the other situation: the allergy is confirmed, and now you have to feed a small person three times a day around it. Here is where egg hides, what the label actually tells you, and what genuinely replaces egg in the kitchen.

This page is about living with a diagnosis you already have. It does not diagnose anything, and it never advises reintroducing egg in any form. Your allergist owns that decision.

Where egg hides

The obvious ones are easy. These are the ones that catch people out.

🦀
Surimi and imitation crabEgg is a standard binder in imitation seafood.
🍜
Pasta and noodlesFresh and egg pasta contain egg. Most dry boxed pasta does not, but check.
🥖
Anything with a shiny glazeEgg wash gives breads, pastries, pretzels and some sweets their gloss.
🥫
Dressings and saucesMayonnaise, hollandaise and Caesar dressing are egg-based.
🍬
Marshmallow, nougat, meringueWhipped confectionery is often built on egg white.
🍗
Breaded and battered foodsEgg is the glue that holds crumb to chicken, fish or vegetable.
🍚
Fried rice and some Asian dishesEgg is frequently folded through and not obvious on the plate.
🥣
Meatloaf and meatballsEgg binds the mix. This is also a USDA-regulated category, see labels below.

One that appears on older avoidance lists and is worth calming down about: lecithin. Almost all lecithin in packaged food is soy or sunflower derived. Egg lecithin exists but is rare, and on FDA-regulated packaged food, where it is used the label has to say egg anyway.

The label names that mean egg

Egg travels under a lot of names. These are the ones on current authoritative lists:

Eggs from other birds are treated as egg for avoidance purposes too: duck, goose, quail and turkey egg all stay off the menu unless your allergist says otherwise. One name, Simplesse, appears on some lists and not others. It is a fat replacer made from whey and/or egg white protein, so if you see it, treat it as a reason to check rather than ignore.

What the label law does and does not cover

Egg is one of the nine major allergens in the US, so on most packaged food it has to be declared in plain English, either inside the ingredient list or in a "Contains: Egg" line. That is genuinely useful. What it does not do is the part worth knowing:

Cooking without egg: work out what the egg was doing

This is the thing that makes egg-free cooking click. Egg does three different jobs, and each one has a different swap. Using a binder swap where the recipe needed lift is why egg-free baking sometimes comes out flat and sad.

Binding (burgers, fritters, most quick breads)

Per egg, any one of these:

Moisture (pancakes, muffins, quick breads)

A quarter cup per egg of mashed banana, avocado, sweet potato, pumpkin puree or silken tofu.

Lift (cakes and anything that needs to rise)

Per egg, one and a half tablespoons of oil plus one and a half tablespoons of water plus one teaspoon of baking powder. Baking powder and baking soda are not interchangeable here. A common alternative swaps in baking soda plus vinegar, which works, but note that a teaspoon of baking soda adds a lot of sodium to the batch, and that matters more when the person eating it is a baby.

For a glaze where a recipe wants beaten egg white, melted dairy-free margarine gives you the shine without reaching for another common allergen.

Where substitutes genuinely fail: recipes calling for three or more eggs per batch, and sponge, angel food and pound cakes. Those depend on egg structure. It is less frustrating to bake something else than to rescue them.

Nutrients worth keeping an eye on

Egg is a compact source of protein, iron, biotin, folate, riboflavin, and vitamins A, D, E and B12. Removing it is very manageable, but it is worth being deliberate rather than assuming it works out. Meat, fish, poultry, legumes, fortified grains, leafy greens and, if they are safe for your child, dairy all cover this ground. If your child has several allergens removed at once, that is a good reason to ask for a referral to a paediatric dietitian rather than working it out alone.

Baked egg is an allergist question

You will read that some egg-allergic children tolerate egg that has been baked into a product. That is a real thing, and it is assessed and introduced under allergist supervision, sometimes after testing or a supervised feeding. It is not a kitchen experiment, and a batch of muffins is not a trial. If you want to know whether it applies to your child, that is the appointment to ask for.

Frequently asked questions

Can I just remove the yolk and keep the white, or the other way round?

No. Most reactions are to egg white protein, but you cannot separate the two cleanly: traces of white end up on the yolk every time. Guidance is to remove both. If someone has told you your child tolerates one part, that came from an allergist who tested it, and it is not a decision to make at home.

Does the label have to say "egg"?

On most packaged food in the US, yes. Egg is one of the nine major allergens, so it has to appear either in plain English in the ingredient list or in a "Contains: Egg" line. But that law does not cover everything. Meat and poultry products are regulated separately by USDA, so a breaded nugget or a meatloaf-style product may not carry a "Contains" statement. It also says nothing about cross-contact, a real risk no label is required to mention. And "may contain" warnings are voluntary, so their absence does not mean a product is safe.

What replaces egg when I am baking?

It depends what the egg was doing. As a binder, per egg: half a mashed banana, or a quarter cup of applesauce or fruit puree, or one tablespoon of ground flaxseed or chia in three tablespoons of warm water left to sit a few minutes. For moisture, a quarter cup of mashed banana, avocado, sweet potato, pumpkin or silken tofu. Fruit purees do change the taste and density of the result, which is normal.

Is there anything egg substitutes simply cannot do?

Yes, and it is worth knowing before you waste an afternoon. Recipes calling for three or more eggs per batch generally do not work with substitutes, and sponge, angel food and pound cakes depend on egg structure in a way nothing replicates. For those, it is usually easier to make something else than to rescue the recipe.

Can my child have their vaccines?

Yes, and this has genuinely changed, so a lot of parents and even some offices are working from old information. Since the 2023 to 2024 season, CDC guidance is that egg allergy of any severity needs no extra precautions for flu vaccination at all: any age-appropriate flu vaccine, in an ordinary vaccination setting, with only the safety measures that apply to everyone. The older rule that a severe egg reaction meant vaccinating in a medical setting was retired that season. MMR is not an egg concern either: it contains no meaningful egg protein and current guidance has no egg-allergy precautions for it. If your clinic prefers extra caution, that is practice style rather than CDC guidance. Confirm the plan with your own pediatrician, who knows your child.

Will my child outgrow it?

Many children do, and egg is one of the more commonly outgrown allergies, but the timelines in circulation vary a lot between studies and none of them predict an individual child. Your allergist tracks this over time and decides if and when anything is retested. Nothing about outgrowing an allergy is something to test at home.
