You Tube demands more and more fresh content. So you are doing a right thing posting one video a day. If you can increase the frequency then it will be more good.
Try to create long form videos whenever possible (Longer than 5 minutes).
But I know it will be very challenging for you to create more videos per day. Just like you are a Food Recipe niche You Tuber, I am a DIY art and Craft niche creator. I have my team who works with me and I know how tedious and cumbersome it is to regularly create fresh content.
But do not give up. Mix your strategy with community posts, and replying to the comments of users, without fail. Soon you will have a very good followership and community built around your channel.
Also keep posting the content links on other social platforms without worrying that you have less followers there. Followers will increase over a period of time, so do not worry about it.
Stay positive, keep producing good quality content - that's all.
My best wishes for you!
