How to Make Perfect Boiled Eggs Every Time

It can be difficult to know when that egg is perfectly cooked.

Rest assured, we have a few tricks to get you that perfectly soft or hard boiled texture you’re after.

How To Boil Eggs

It’s almost as easy as boiling water.

1. Choose The Right Eggs

  • This is the first step in your hard or soft boiled egg adventures. Using eggs that are 1-2 weeks old is ideal. As the egg ages, the membrane separates from the shell, making it easier to peel.  
  • If you only have fresh eggs, consider adding vinegar to the water to make peeling easier
  • Use large eggs every time to take the guesswork out of when they are done

2. Store Eggs Tip-Point Down To Center The Yolk

This assures that the yolk is perfectly centered and ready to be filled. Food stylists use this trick when boiling eggs that need to look perfect. Simply store your egg cartons upside-down in the fridge.

3. Add Salt To The Water

  • Salt raises the boiling point of the water slightly. This helps the egg white cook a bit faster, which makes it harder to over cook the yolk.
  • Helps seal cracks  If a crack develops, the salt will aid in coagulation. That allows it to seal faster when it hits the salt water.
  • Some salt actually permeates the egg shell. It’s not enough to taste, but it helps with peeling.

4. Peeling Eggs

  • Boiling eggs in water with vinegar softens the shells and makes them easier to peel.
  • Dropping cold eggs into boiling water and then cooling them in an ice bath also makes a slight difference.
  • Eggs are also a little easier to peel freshly after hard-boiling.

To peel an egg with no extra ingredients or equipment, crack the egg all over on the counter, then roll, pressing slightly till it’s cracked all over.

Then peel.

Or peel hard-boiled eggs under running water to help release the shells. 

The water pressure pushes the shells off the eggs and washes them right off.

It’s not magic, but it makes peeling them easier.

Tip #1: To prevent egg shells from cracking, poke holes in the wider end of the egg before boiling.

This is where the air pocket is located. Use a push pin to poke the hole(s). 

Tip#2: You can also let your eggs sit out at room temperature (for 20 minutes) before boiling them to avoid cracked shells.

5. The Best Pot For Boiling Eggs

Choose a pot that’s large enough so that the water can boil rapidly without spilling over and so that the eggs have plenty of room.

The type of pot should not make much difference.

You can also use an egg cooker or bake the eggs in the oven.

6. Use Enough Water

  • Fill your pot with about enough water to submerge the eggs, then bring to a boil.
  • It’s important they don’t overlap and the pot isn’t too crowded so they all cook at the same time.

Or dunk them in a bowl of ice water.
