From your description, I imagine your recipe starts on a new page (through the page break option of Heading 2 style).
In this case, you could have an automatic title in the header area. For that, you need to enabled numbering on your Heading 2 in Tools
>Chapter Numbering
.
Next, you configure the page style you’re using. I suggest not to use Default so that you can keep it for cover, introduction or any other non-recipe page.
Modify the page style in the Header
tab: enable header and uncheck Same content on first page.
When this is done, put your cursor in the header area of a recipe first page. Insert
>Fields
>Other
. In Tab Document
, select type Headings, format Chapter Name (or Heading Name, depends on locale) and leave level at 1.
Do the same for a second page of a recipe, adding “(continued)” or any other text to your liking. Eventually, force a second page by typing empty paragraphs. Once the second heading is recorded, you can erase the extra paragraphs.
