If you want it 98% of the time, try it in a pressure cooker. Egg setting to five minutes instead of three. Bam! You got yourself some hardboiled eggs for your sandwiches, for your toast, for your whatever.

Come to think of it, the pressure cooker is perhaps the new air fryer in the sense that it's really handy to have and people who own one cannot shut up about it. Can you blame them after these perfect eggs?

Can confirm this works almost always even with fresh eggs. Caveat: 5 minutes of pressure cooking also means a few minutes to heat up/pressurize, the 5 minutes of cook time, and 5+ minutes of natural depressurization, so don't time everything else around the 5 minute thing. I have yet to try forced depressurization, so YMMV.
