I don’t know if anyone here has been through this… but I eat a lot of fast food because I have a fear of using anything to cook, if it’s for me to make something like bread and butter, that’s fine, it’s just a fork that I need, but when it comes to using a furnace or those kind of things, I just have a fear I might mess up somehow and start a fire or something… I know it sounds stupid but it’s a nightmare I have in my head for some reason =/, I thought I’d try getting over it so I could cook my own meals and get more healthy but thar’s a barrier stopping me… can anyone who has been through this give me any advice on it?
If you have the features, learn how the timer system of your appliances works. My family has never figured them out and screws stuff up regularly because of inattention. I'm disabled and I know better than to trust myself. I set timers to start and stop stuff that is cooking in the oven. If I want something hot at a special time, I just set a delay timer that turns on my settings and then has a stop timer. If there is absolutely any doubt that a dish in the oven may leak, I place a pan on another lower rack to catch absolutely anything that might potentially leak. I tend to cook 2 weeks worth of food at one time in the oven and just arrange all the stuff so that the potential leaks are onto other safe stuff.
I also do not bother with recipes. Most ovens have terrible temperature controllers, so times and settings are largely useless in reality. My secret is to start with boring but edible food. In reality, you likely do not eat some great variety of foods. Fundamentally it is the same 2-4 meats (sorry vegans), bread, and some veggies. So I started by filling a large glass casserole pan with green beans, broccoli, and cauliflower, a second pan I fill with corn on the cob, a third I do a bed of sliced onion and a meat on top with seasoning, and I finally have a covered glass bowl for cooking two cups of rice. I eat this steamed rice for 2 days before making homemade fried rice. Well made fried rice will easily last the remainder of 2 weeks. The meal is mostly rice, with some veggies and a few ounces of meat. This is my only full meal each day. I cook that on whatever my oven calls 450° F for 1 h 20m. It does not require any oil or anything else. While it is edible like this, the last trick is to make a sauce with half a jar of mayo, about a quarter of the jar filled with the best teriyaki sauce you can find, and a small amount of sriracha sauce to taste. This sauce can be further improved slightly with any small amounts of savory sauces from pickling or fermentation or in more simple terms, the juices from a jar of whole olives, peppers, old alcohol, left over pan glazing stock, etc., or like Worcestershire or soy sauce if you have trouble with these abstractions.
Form a boring baseline of food, then start tuning this baseline to make it better over time. If you limit yourself to this kind of repetition, you’ll eat much more consistently healthy, but also you’ll really learn how to cook using abstracted information and a deeper understanding of your available tools.
I do this with everything. I occasionally make some cookies that just go in the oven. The whole preheating your oven thing is just an attempt to make recipes transferable. The controls on your oven are likely way off and the control algorithm or temperature switches are extremely inconsistent. People do not make these appliance purchases in general while shopping for these features. Therefore these corners are cut in most hardware. I just ate the same cookies enough to know exactly how long they cook for with my favorite properties. I cook them for 22 minutes at 475° F from a cold start. I can put that on a start and end timer and have hot cookies any time I want. If there is a high probability that I will not be present or available when they are done, 20 minutes at 450 will produce good results if they remain in the oven as it cools down.
Using the timers means you can never forget something in a way that is catastrophic. I don’t recommended running an oven unsupervised, but you can take precautions to enable failsafes like pan under pan setups.
