The answer to this depends on how hot your oven runs as well as the size of the fresh eggs used but generally, you’re looking at anywhere between 20-25 minutes of oven time.  For a beautiful soft-boiled egg that isn’t too runny, you’ll need to bake your eggs for about 25 minutes while a soft and runny boiled egg will only need 20 minutes. Then obviously, the closer you reach the 30-minute mark, the harder your boiled egg will be.
