You don’t need to slave over a stove for 3 hours to get caramelized onion. Here’s what you do. After slicing the onion, get the pan up to a medium heat with a splash of oil. Toss in the onions and add a bit of salt to make them sweat. Once they start to dry out, go golden at the edges, and even stick to the pan a bit, add a splash of water. You do have to stir continuously for this method as well, but it takes much less time. Do this process a few times where you add water, cook it until its dry, another splash of water, cook it until it dries out again, etc. Sometimes I’ll even alternate in a splash of white wine for fun. You should have beautiful caramelized onions in 30 min with this method.

Clean as you go, don't just leave it all for the end. Onions are sauteing and you're done chopping everything? Good, wash your cutting board and knife and clean up any messes before the next step. Sausage is done browning and you're dumping it in with the onions for a minute with the garlic and some herbs? Great, wash that pan and spoon and set it down to dry and wipe up all the oil splashes.

Just makes clean up so much easier after you've eaten and you're much more efficiently using your time.
