There are lots of ways to find recipes online, but not all are good ways to learn to cook.
The problem with cookbooks is that they don’t always explain the processes in any real detail, as they assume a basic level of knowledge. Cookbooks intended for kids might be better, but you have to find the right level so it’s not simply ‘assembly’.
There are cookbooks out there that are intended to be for college students, which may be better, as they assume inexperience, lack of time, expensive equipment, and that you’re not cooking for a large family.
Videos and cooking TV shows may help, but again, it’s a wide range. Some are more ‘recipe inspiration’ than how to actually cook. Rachel Ray’s first show (30 Minute Meals) appealed to this audience, but she still was cooking for a larger crowd with more equipment than someone starting out would have (I suspect it would also require 30 minutes of doing the dishes)
Food Network also had a show called “How to Boil Water” in which they had a professional working with an inexperienced person who would ask them why they were doing things. NHK’s “Dining with the Chef” uses this, but as with How to Boil Water, they’ve had the same pairs for so long that the hosts aren’t asking the basic questions as much these days.
If you have it, my suggestion would be to try to find someone who knows how to cook. Offer to supply ingredients in exchange for cooking lessons. Actually cooking with someone will mean that someone is watching you to catch your mistakes. Although in some cases, you have to be quick— I was teaching a friend’s son to make pasta, and he didn’t listen to the ‘stir from the middle’, and he turned it into a lump that I was unable to recover from easily. (I should’ve started over; luckily, we were making two batches)
It’s also worth mentioning that there are a lot of bad cookbooks and videos out there. Even Alton Brown has had to issue corrections for some of his recipes, like his fondue when he didn’t realize that he had developed it with an abnormally acidic ingredient, so it failed for others. He actually has a series where he went back and corrected many of his past shows (Good Eats Reloaded)
America’s Test Kitchen (on PBS) is another good show as they explain a little bit about why they’re doing things, and strive to make recipes that will reliably work.
