Baked egg home introduction

Please read the whole of this resource before starting a home introduction of baked egg. This resource should support you to do the baked egg introduction at home. This resource is only to be used as a guide. If your child has individual needs, your child’s dietitian or doctor will explain this for you.

Many children with egg allergy grow out of it in early life. As the allergy improves with time, many children will initially tolerate well-cooked (baked) egg products before they can eat lightly cooked or raw egg.

It is appropriate to try introducing baked egg at home in some children where there have only been mild reactions to egg, for example:

  • hives
  • swelling
  • acid reflux
  • flares of eczema

Children who have had more severe symptoms such as breathing difficulties or collapsing, will need to have their introduction done under hospital supervision.

You should introduce baked egg over a period of weeks, rather than over one day as you may have seen happening in hospital.

What foods should I introduce?

Start by baking small plain cupcakes (without icing) made with 1 egg to every 8 cupcakes (see recipes further down this resource).

Once your child can eat a whole cupcake (made with 1 egg to every 8 cakes), you must then do the same again, but this time with a cupcake made with 2 eggs to every 8 cakes (so it has more egg in each cake.) It is fine to use a savoury rather than sweet recipe.

You can also use plain shop-bought cupcakes (without icing or chocolate chips) as an alternative.

If you do not want to use cupcakes, instead you can use mini-potato cakes (see recipe further down this resource). Gradually up to 2 mini potato cakes in the same way you would with the cake.

How do I do the introduction?

If you child is unwell, do not start the introduction until they feel better.

Have child’s usual antihistamine medicine available just in case.

Week 1

  1. Begin by giving your child a small crumb of cake to eat. Watch them carefully for any sign of allergic reaction.
  2. Give them a small crumb every day for a week.

Week 2

  1. Give your child a pea-sized crumb of a cupcake once a day for 2 days
  2. Then move on to give them a 16th of a cupcake once a day for 2 days

Circle with 16th segment

  1. Then move on to give them an 8th of a cupcake once a day for 3 days

Circle with 8th segment

Week 3

  1. Give your child a quarter of a cupcake once a day for 7 days

Circle with 4th segment

Week 4

  1. Week 4: give your child half of a cupcake once a day on 3 occasions over the week

Circle with half segment

Week 5

  1. Week 5: give your child a whole cupcake once a day on 3 occasions over the week

Circle with whole segment

You may stay at each stage for longer than as shown above, but do not increase to the next “dose” more quickly. Try to give the dose every day. If you miss several days, such as if your child is unwell, give them a smaller dose when you restart and build up.

Do not increase the dose if your child is unwell. Keep them at the same dose that they have already been tolerating.

What if my child has a reaction?

Symptoms of a reaction usually occur up to 2 hours after the last dose. Signs of an allergic reaction to watch out for include:

  • itching
  • redness
  • swelling
  • hives (nettle-sting type rash)
  • being sick
  • wheezing

If you notice these, treat your child as per their allergy plan and stop introducing baked egg.

If your child gets mild tummy upset or eczema flare you can continue with the introduction, going up more slowly than above.

What do we do after the introduction?

Do not allow your child to eat any other foods containing egg until 1 whole cupcake (with 2 eggs in 8 cakes) or 2 potato-cakes are managed without a problem.

You can then introduce other well-baked egg foods such as:

  • sausages or Quorn baked in the oven
  • frozen Yorkshire puddings cooked in the oven
  • shop-bought scotch pancakes, waffles, brioche, croissants
  • breadsticks
  • bread made with egg such as Nimble, and some gluten-free breads such as Genius

Homemade pancakes, homemade Yorkshire puddings and brownies are not suitable as the egg is not cooked enough.

You can also give egg containing breadsticks and bread alongside other baked egg foods. However, as these only contain egg white, it is best to also make sure your child also has other baked egg foods with whole egg in regularly. This is to make sure your child can also tolerate eating baked egg yolk.

Start with small amounts of these new foods and build them up gradually. Once your child is freely eating baked egg foods you can also try them with egg pasta.

Aim for your child to eat baked egg 2 to 3 times a week. Do not worry if your child does not like to initially eat products with egg in, this is quite common.

We also have recipes for sausage rolls and burgers that we can share with you, just contact the Allergy nurses or dieticians if you would like a copy.
