Ingredients

Scale

Gnocchi Dough

  • 1 cup leftover mashed potatoes (cold, straight from the fridge)
  • 1 egg
  • 1 pinch salt
  • 1 to 2 cups all-purpose flour, divided (start with 1/4 cup and add as needed)

Instructions

  1. Combine Ingredients: In a large mixing bowl, add the leftover mashed potatoes, egg, and a pinch of salt. Mix gently to combine these main ingredients.
  2. Add Flour Gradually: Stir in 1/4 cup of flour initially, then continue adding flour 1/4 cup at a time. Use a spoon or spatula for the first addition and then your hands to knead. The dough should become soft and pliable but not sticky, without overworking to avoid chewy gnocchi.
  3. Prepare Workspace: Lightly flour a large cutting board and a sheet pan or plate to prevent sticking when shaping the dough.
  4. Shape the Dough: Cut the dough into 4 or 5 sections. Roll one section into a long rope about 1 inch thick on the floured board. Dust with extra flour if the dough sticks.
  5. Cut Gnocchi Pieces: Slice the rope into 1-inch pieces. These pieces form your gnocchi. Optionally, roll each piece over a gnocchi board or fork tines to create ridges, which help sauces cling better.
  6. Boil Water: Bring a large pot of salted water to a rolling boil.
  7. Cook Gnocchi: Carefully drop the gnocchi into boiling water, stirring gently to prevent sticking. Cook for 2-3 minutes or until they float to the surface. Once floating, remove with a slotted spoon and drain well.
  8. Serve: Toss the cooked gnocchi with your favorite sauce and serve immediately for a comforting and satisfying meal.

Notes

  • Use cold leftover mashed potatoes for best dough texture and easier handling.
  • Be gentle and avoid overworking the dough to prevent gummy or tough gnocchi.
  • Flour amounts may vary depending on moisture content of the mashed potatoes; it’s important to add flour gradually to achieve the right softness.
  • Rolling gnocchi over a fork or gnocchi board creates ridges that help hold onto sauces better.
  • Serve gnocchi immediately after cooking as they are best fresh and soft.
