I found that it really just comes down to how much experience you have. I started cooking a lot this year, mostly because it beats taking my girlfriend out to dinner every week. When I started I was very slow and dinners would take me in excess of an hour, mostly because I was just very unskilled in the basics of cooking.
As time has gone on I found that making dinners took me less and less time, part of it is knowing the right techniques for preparing certain foods, others are little ergonomic things like getting a knife magnet and ensuring all the tools you need are at your fingertips. It's also knowing how long food cooks for, what you have to keep an eye on and what you can just let cook. The first time I made smash burgers at home it took me in excess of an hour to prep and cook everything and yesterday I was able to do the same in about 20 minutes.
