Cacio e pepe, everyone’s favorite new pasta dish, is what it is thanks to two ingredients in particular: parmesan cheese and black pepper. Oh, and butter. Lots of butter. No wonder people like it.

The last time I was eating it, I was thinking about what other dishes these flavors could be added to, and potatoes popped to mind. I will happily eat a massive bowl of any mashed potatoes all on their own, but if these cacio e pepe mashed potatoes are around, I just don’t have a choice.

What to Serve with Mashed Potatoes

Like I said, I’d happily eat a bowl of these on my own, but I do get that might be “frowned upon.” Here’s what I’d serve as the main course with these mashed potatoes:

Tips for Cacio e Pepe Mashed Potatoes

  • Make sure your water for boiling is thoroughly salted – taste it! It should taste salty.
  • Be generous with the black pepper. The mashed potatoes should almost taste spicy.
  • Taste the mashed potatoes as you add ingredients, and keep adding until they’re perfect.
  • I recommend using a potato masher for these – this method helps prevent “gluey” and overworked mashed potatoes.
