Egg salad is five ingredients and about twenty minutes, and almost everything that goes wrong with it happens in the first five of those minutes, at the hob. Below are the questions I actually get asked about it, in the order they tend to come up, answered the way I do it at home.
Prep: 10 mins Cook: 10 mins Serves: 4
How do I boil eggs so they peel cleanly, and how long do they actually need?
Lower them into water that is already at a rolling boil. Do not start them in cold water and bring it up together.
That is the single change that fixed peeling for me. A cold start warms the egg slowly and the white sets against the inner membrane, so it tears off in flakes and takes half the white with it. A fridge-cold egg dropped into boiling water gets a fast blast of heat on the outer white, which helps it shrink away from that membrane. Lower them in one at a time with a slotted spoon so they do not crack on the pan floor.
Ten minutes at a gentle boil for a large egg gives you a fully set yolk that is still bright yellow and slightly fudgy in the centre. Twelve minutes and it is chalky. Fourteen and you get the grey-green ring.
That ring is iron in the yolk reacting with sulphur from the white, and it needs prolonged heat to form. It is harmless, and it tastes faintly sulphurous, which is enough reason to avoid it. Ice water immediately after cooking stops the process cold. I give mine 5 minutes in a bowl of water with a handful of ice.
Older eggs peel more easily than very fresh ones. If you have a choice, use the ones that have been in the fridge a week.
Ingredients
- 6 large eggs.
- 3 tbsp mayonnaise.
- 1 tbsp full-fat Greek yoghurt or soured cream.
- 1 tsp Dijon mustard.
- 1 tbsp celery, finely diced.
- 1 tbsp chives or spring onion, chopped.
- 1 tsp lemon juice.
- 1/4 tsp fine salt, plus more to taste.
- Black pepper, plenty.
- 8 slices of bread with a firm crumb, or 4 rolls.
- Butter, for the bread.
- Lettuce leaves, optional.
Instructions
- Bring a pan of water to a rolling boil. Lower in the eggs one at a time with a slotted spoon and cook at a steady boil for 10 minutes.
- Move them straight into a bowl of ice water for 5 minutes.
- Peel under a slow-running cold tap. Crack the fat end first, where the air pocket is.
- Chop the eggs into pieces roughly 1cm across. Keep some larger.
- Mix the mayonnaise, yoghurt, Dijon, lemon juice, salt and pepper in a bowl until smooth.
- Fold in the eggs, celery and chives with a spatula. Fold, do not stir, so the pieces stay whole.
- Taste. It will almost always want more salt and more pepper than you expect.
- Butter the bread right to the edges, add lettuce if using, spoon on the egg salad and press the sandwich together gently.
Mayo alone, or mayo plus something?
Plus something. Straight mayonnaise makes a filling that coats your mouth and flattens out after two bites, because it is essentially oil and there is nothing in it to cut through.
My split is 3 tablespoons mayonnaise to 1 tablespoon full-fat Greek yoghurt, with a teaspoon of Dijon and a teaspoon of lemon juice. The yoghurt brings tang, the Dijon adds sharpness and helps the dressing hold together, the lemon lifts it. You still taste mayonnaise. You just stop tasting only mayonnaise.
Soured cream works in place of the yoghurt. Low-fat yoghurt does not, and this is where thin, weepy egg salad usually starts.
Mix the dressing in the bowl before the eggs go anywhere near it. Adding mayo to chopped egg means you overwork it trying to distribute it.
How finely should I chop?
Not as finely as you think. Aim for pieces around 1cm, and deliberately leave a few bigger.
Chop it to a paste and you have lost the reason egg salad is good, which is the contrast between soft yolk that dissolves into the dressing and firm white that stays as a distinct bite. A uniform mash tastes of one thing.
The method I settled on: quarter each egg lengthways, then cut across three times. Six eggs takes under two minutes. An egg slicer used twice at right angles works too, but a knife gives you more control over how uneven it stays.
If you want a smoother version for kids, mash two of the six with a fork and leave the rest chunky. You get creaminess without losing texture. It is the same logic behind the filling in classic deviled eggs, where the yolks are smooth and the whites stay firm.
Why does mine go watery in the fridge?
Salt. It draws water out of the egg whites, and after a few hours that water pools at the bottom of the container and thins the dressing.
Two things help. Salt at the end rather than at the start, and keep the celery to about a tablespoon, finely diced, because celery is over 90 percent water and it releases most of it overnight.
Watery raw additions are the other culprit. Chopped fresh tomato or cucumber in egg salad you plan to keep will turn it into soup by morning. Add those to the sandwich, not the bowl.
If it has already gone thin, tip the container so the liquid gathers at one edge, spoon it off, and stir in an extra teaspoon of mayonnaise. Perfectly fine.
What bread actually holds up?
Something with a firm, close crumb: a decent white sandwich loaf, sourdough cut about 1.5cm thick, or a soft roll with structure. Toasting one side of each slice and turning the toasted faces inwards buys an extra hour in a lunchbox.
Butter both slices to the edges. It is a waterproof layer, and it does more for sandwich survival than any bread choice. My mother-in-law does not butter and then complains her sandwiches go limp by eleven.
Fresh, very soft supermarket white gives up almost immediately. So does anything with big open holes, like ciabatta, where the filling drops straight through.
For the same reasons the bread in a classic BLT sandwich matters, it matters here.
How long does it keep?
Three to four days in an airtight container in the fridge at 5C or below. I would eat it within three.
Out of the fridge, two hours is the limit, one hour if the room is above 32C. Egg salad sits in the range where bacteria multiply fastest and gives almost no warning: it looks and smells fine well past the point where I would eat it. A packed lunch needs an ice pack, not optimism.
Do not freeze it. Mayonnaise separates on thawing and the whites turn rubbery. I tried it once, out of curiosity, and threw the lot away.
If you have made it ahead, give it a stir before serving and check the seasoning again. Cold dulls salt.
Can I make it lighter?
Flip the ratio: 2 tablespoons of Greek yoghurt to 1 of mayonnaise, plus half a teaspoon more Dijon and a little more lemon to make up for the fat you removed. Noticeably tangier, still creamy.
Better still, drop two of the six yolks. Almost all the fat in an egg is in the yolk, and four yolks with six whites keeps the colour and richness while cutting the total. This is the version I make most.
Half an avocado mashed in works and tastes good, but it browns, so make it only for the same day.
One more thing worth knowing: this filling is excellent on an open slice under the grill for 3 minutes, the way you would build a tuna melt, with a spoonful of creamy coleslaw alongside. The heat firms up the whites and makes the dressing taste richer than it is.
