Joplin is already mentioned but I’d point out it can import those 15k recipes. You do have to do a notebook at a time though (that took me a bit as I had over 300).
There are plugins for various functionality like OCR and hotfolders (auto import). I hear the webclipper isn’t great but I’ve never used it in my workflow in Evernote or Joplin.
I finally bailed after 13+ years of Evernote about a year ago to Joplin and am very happy overall.
