My family always comes back for seconds of this dish. I started cooking it when I wanted something impressive but honestly needed a recipe that lets me spend more time at the table than in the kitchen. The combination of tender pork and herby potatoes wins every time.

Potatoes are my favorite part here I love how the edges get golden and crisp especially when a bit of pork juice seeps underneath When I served this last Sunday my nephew asked for extra potatoes over meat so you know they steal the show sometimes
