I think if you like cooking, it's easy to fall into the trap of meals that are a bit more fiddly/take longer. Add in the complexities of any fussy eaters/food intolerances and, if you're me, the reality that sometimes cooking dinner is the one bit of "downtime" I get.... and bang, dinner is at least an hour a day .
I try to plan certain specific meals that I know I can easily prepare in less than 30 minutes for the days I know I don't have as much time. eg tonight we're having salmon fillets which I'll cook in the air fryer and then we're just having a sort of stir fry/sauted vegetables made with sliced red onion, cabbage, cavalo Nero and garlic with some rice noodles that just have to be placed in hot water. In all, the whole thing shouldn't take more than 20-25 minutes, tops.
Basically, anything that has multiple steps, or multiple "elements" (as they say on Masterchef!) usually takes longer. Anything that can all just be tossed in one pan/pot - is quicker. Ditto, the more chopping and slicing you have to do, the longer it takes, no matter how good you are at chopping/slicing.
That's my basic rule of thumb. So spaghetti bolognaise might take a while to actually cook/simmer, but it's 20 minutes or less of active preparation time then I just leave it while I'm doing something else. But if I cook the mince in our other favourite way which is a sort of asian-style stir fry, it takes longer. Partly because I do more chopping as I add LOAD of vegetables, and partly because I can't cook it all at once in one pot so have to do the mince, then the veg, then the noodles then bring it all together.
I work from home so I also sometimes use lunch time to do prep. so Spag Bol, as above - I might do the prep at lunch then leave to simmer for part of the afternoon. Sometimes I do puff pastry tarts and I usually pre-bake them earlier in the day and if I have time, sauté the onions/leeks or whatever I'm adding so that I just have to assemble and heat the tart at dinner and make a salad while it's in the oven.
