Would a shallow ocean planet be possible?

For a story I am writing, I need a planet covered in a shallow ocean. What I mean is that I want the majority of the planet's surface (=> 60%) to be in the photic zone of the ocean.

This planet must sustain life, with the most intelligent being some smalamanders. Ideally this planet can remain habitable until my smalamanders evolve into smalamen, but I am not opposed to benevolent aliens changing the conditions to be more suited to life. (And if necessary, the topography of the planet.)

What kind of environmental or planetary factors could achieve this?
