If you are just starting out, ty cooking something that you really enjoy, which is more of a one-pan/pot dish. Something that should take less than an hour. Make notes on how it tasted, how the protein felt to the touch (hard, firm, bouncy, soft, etc.), timing differences, texture while eating (dry, wet, soft, hard, etc.), things you would do differently next time. If you are confused about how things went, ask for help and suggestions. Take notes on those. And then cook the same thing again soon after. It will probably be better. Repeat until you feel confident.

Celebrate the win!

Next make something different but with the same main ingredient. Repeat that until it's to your liking.

Once you repeat this a few times with different dishes you will find that you build up some intuition about the ingredients. Then it's easier to branch out to other recipes and other foods.

Lots of people talk about meal prep for a week. Don't get sucked into doing that until you are confident with a specific recipe and how it keeps leftover. You will build skill if you cook one meal at a time. Limit the time needed and ingredient cost so that a bad outcome doesn't feel so bad.
