It’s probably cliche but if you’re into youtube tutorials Basics with Babish is a great place to start. He teaches simple dishes that taste great and teach different skills. Another way to learn is to do one of the all in one delivery meal like hello fresh. It’s expensive but still affordable and it’s really good practice. If you dont want to spend on it you can also just get the recipes online. Also, if you find a dish a you really like you can make it whenever.
