Egg Introduction for Baby: Safe Dosing & Cooking Guide

If you’re starting egg introduction for baby, egg is one of the trickiest allergens to introduce — not because the dosing is complicated, but because how you cook it changes how allergenic it is. Raw and undercooked egg white holds onto proteins that are far more likely to trigger a reaction than the same egg fully cooked. If you’re standing in your kitchen wondering whether scrambled is safe, whether the yolk alone counts, or how much egg your baby actually needs — this is the guide we wish we’d had. Below is the exact schedule, cooking method, and dosing table we used, built on the same framework allergists recommend for early egg introduction.

Egg for Baby: 2 Safety Checks Before the First Taste

Before the first taste, confirm both of these with your pediatrician:

1. Your baby is developmentally ready for solids — typically around 4-6 months. Babies with moderate-to-severe eczema or an existing food allergy (especially peanut) may need an allergy evaluation first, since egg and peanut allergies often travel together.
2. You have a previously tolerated carrier food ready — oatmeal, mashed avocado, or a puree your baby already eats without issue. Never introduce egg in a brand-new food on the same day.

Why Cooking Method Matters More for Egg Than Any Other Allergen

This is the part most parents miss. With peanut, the protein is fairly stable whether it’s roasted or raw. Egg is different — the proteins in raw and lightly cooked egg white (particularly ovomucoid) are heat-resistant and stay allergenic even after light cooking. Fully cooking the egg — until both the white and yolk are completely firm — breaks down these proteins and makes a reaction far less likely.

What this means in practice: scrambled “just set” eggs, soft-boiled yolks, French toast with a runny center, and baked goods with undercooked batter are not the same as a fully hard-boiled or well-scrambled egg. For first introduction, fully cooked is non-negotiable.

The 12-Minute Safe Hard-Boil Method (Step-by-Step)

This is the method we used for every first introduction — it’s foolproof and gives you a consistent, fully-cooked result every time.

1. Place the egg in a small pot and cover with cold water by about an inch.
2. Bring to a full boil, then remove from heat, cover, and let sit for exactly 12 minutes.
3. Transfer to an ice bath for 5 minutes to stop the cooking and make peeling easier.
4. Peel and check the yolk — it should be fully firm and pale yellow all the way through, with no soft or glossy center.

5. Mash the portion you need with a fork until smooth, then thin with breastmilk, formula, or water to your baby’s usual texture.

Egg Introduction for Baby: Weekly Dosing Schedule

Use this table as your weekly guide. Print it out and keep it on the fridge.

Once your baby reaches the half-egg dose and tolerates it across one full week, you’ve hit the maintenance phase.

The Maintenance Phase: Why You Cannot Stop

Just like with peanut, successfully introducing egg on Day 1 doesn’t mean the job is done. Tolerance is maintained through consistent, repeated exposure — not a one-time taste test. Stopping after a few successful feeds can allow sensitivity to develop over time, which is the opposite of what early introduction is meant to achieve. For more on the research behind this approach, the AAP’s guidance on early introduction of allergenic foods is a useful starting point.

The maintenance target for the rest of your baby’s first year:

• About 1/2 of a whole cooked egg (~2g protein)
• 2-3 times per week
• Mixed into food they enjoy and will reliably eat

What to Do If You Miss 2+ Weeks of Egg Exposure

A single missed week is unlikely to undo tolerance. If your baby has gone 2+ weeks without any egg, don’t jump straight back to the half-egg maintenance dose. Step back one dose level for a week — say, 1-2 tablespoons of scrambled egg — before returning to the full maintenance amount.

Easiest Way to Cover Egg: Pre-Measured Kits

If you’re already running a kit for peanut, the good news is most multi-allergen kits include egg in the same packet — so there’s nothing extra to prep. For the full breakdown of how these kits compare on price, allergen coverage, and ease of use, read our 5 Best Baby Allergen Introduction Kits review.

Always consult your pediatrician before beginning allergen introduction, especially if your baby has moderate-to-severe eczema, an existing food allergy, or a family history of anaphylaxis.
