Firstly, you should create a new page called ‘Home Page’ or ‘My Cook Book’ (or whatever you’d like):
You’ll find in the Recipe Hero Settings (Recipe Hero > Settings), the ‘Recipe Page’ setting. You can select any page from your WordPress site here and then Recipe Hero will automatically show all your recipes on that page.
Alternatively, you could just create a page and use the [recipes] shortcode to show your recipes.
Then head over to Settings > Reading. Find the Front Page displays option and choose to display a Static Page. You should then select the page you created before, ‘Home Page’, for the front page option. You can select another page for the blog page option that your normal blog posts will be shown on.
Now your home page is the Recipes page!
