How many projects are enough to get a software developer job?

I'm preparing for entry-level software developer roles and wondering how many projects I should have on my resume and portfolio before applying. Some people recommend building many small projects, while others suggest focusing on a few high-quality, real-world applications.

Can someone explain how many projects are typically enough to impress recruiters, what types of projects should be included, and how to showcase them effectively on GitHub and a portfolio website? I'd also like to know what distinguishes an average project from one that helps candidates stand out during technical interviews.
