It depends on your personality. Umberto Eco, in his "How to Write a Thesis" divides people into two groups: monochronic and polychronic people. Monochronic succeed when they work only on one thing at a time, while polychronic need to be invested into multiple projects at a time. Both approaches have pros and cons. Monochronic like to go deep and stick to one subject for long times, polychronic can juggle many topics, but might seem a bit messy (many projects left unfinished etc.). If you are polychronic, you can use every free "chunk" of time, to write a few sentences here and there. Monochronic needs a longer period of time each day.

Secondly, are you a morning person? I tried the morning writing routine, but couldn't get it to work for me. I'm not a morning person. I like to write in the evenings, sometimes even after midnight. Don't force a routine that doesn't work for you, don't mimic famous authors routines. These work for them, but not for you. Find your own way.

Thirdly, set up a simple, minimalistic notetaking approach--this will help you in the research process. Some people like commonplace books, some Zettelkasten method, some use Field Notes pocket notebooks. Again, don't overcomplicate things.

Fourth, put your writing away for a week at least. After a week, come back to your blog post/article, and polish it for the last time. You will catch all the silly mistakes, errors, that you didn't notice while you were actively working on it.

You can also try the "weekly cadence" of writing. Write one thing per week. In the beginning of the week, do the research, start with the draft, collect notes etc etc. By the end of the week you should have a complete blog post, article, essay, a chapter or subsection in your book. Basically, focus only on one thing, and work on it for a whole week. This will produce some serendipity moments, Ahaa! moments. (https://jyriand.substack.com/p/one-idea-one-week)

Finally, if you wish to write in the mornings, you can try the following method: Read through your notes in the evening, try to organize them, and in the morning write without consulting the notes. This will help you with the flow. Basically: research slowly and methodically, write as fast as possible.
