Ingredients

  • 2 cups leftover mashed potatoes
  • 2 egg yolks
  • 1 1/2 - 2 cups all-purpose flour or GF all-purpose flour
  • Pinch of nutmeg
  • Pinch of sea salt or kosher salt
  • Serving suggestion: Your favorite pasta sauce and grated Parmesan cheese

Instructions

  • On a large cutting board or a clean counter, combine the mashed potatoes, egg yolks, 1 1/2 cups of flour, a pinch of nutmeg and pinch of salt. Press the dough together with your fingertips until it comes together and is no longer sticky. If it’s too sticky, sprinkle with a little flour.. The dough should be a firm but also give under gentle pressure. Test the dough: take a piece and roll it with your hands on a well-floured board into a rope 1/2-inch in diameter. If the dough holds together, it is ready. If not, add more flour, fold and press the dough several more times, and test again.
  • Lightly flour the counter. Divide the dough into 4 pieces and roll it out with your hands into a rope about ½-inch in diameter. Cut ½ -inch pieces using a knife or bench scraper. You can leave them as is or make a classic gnocchi shape with a gnocchi board, or the tines of a fork.
  • Bring a large pot of salted water to a boil. Add the gnocchi, in batches if needed depending on the size of the pan. Cook for 1 to 2 minutes or until they rise to the surface. Remove gnocchi with a skimmer or spider and place gnocchi into a bowl and toss with desired sauce and top with Parmesan cheese.

Notes

  • Use smooth, lump-free mashed potatoes. The smoother your mashed potatoes, the better your gnocchi will hold together.
  • Make this recipe vegan by replacing the egg yolks with 2 tablespoons of Greek yogurt or a flaxseed “egg” (1 tablespoon flaxseed meal mixed with 3 tablespoons water).
  • Get creative with your gnocchi by adding your favorite herbs and flavors to the dough. Finely chopped rosemary or thyme can add an earthy, aromatic touch, while grated Parmesan cheese brings a savory depth. You can also try mixing in a little garlic powder or smoked paprika for a flavor twist. Feel free to experiment - this is a forgiving recipe that lends itself to personalization!
