To boil hard boiled eggs, the general recommended cooking time is about 10 to 12 minutes once the water is boiling, depending on how firm you want the yolk:

• For fully hard boiled eggs with firm yolks, boil for 10 to 12 minutes

• Some sources suggest 11 minutes for hard boiled eggs starting with eggs in boiling water

• After boiling, immediately place the eggs in an ice water bath for at least 10-15 minutes to stop the cooking process and make peeling easier

Basic method:

• Bring water to a boil.
• Gently lower fridge-cold eggs into boiling water.
• Reduce heat to a gentle simmer and cook for 10-12 minutes.
• Transfer eggs to ice water bath for 10-15 minutes before peeling.

This method yields eggs with fully set whites and firm, vibrant yolks without greenish discoloration

. In summary, boil eggs for about 10-12 minutes in simmering water, then cool them in ice water for best hard boiled eggs.
