01 - Bring a large pot of salted water to a rolling boil.
02 - In a mixing bowl, whisk together the eggs, egg yolk, grated Parmesan, black pepper, and salt until completely smooth. Set aside.
03 - In a large skillet over medium heat, cook the diced bacon until crispy, about 5–7 minutes. Remove from heat and set aside the bacon, leaving the rendered fat in the skillet.
04 - Add the gnocchi to the boiling water and cook according to package instructions, typically until they float to the surface, 2–3 minutes. Reserve 1/2 cup of pasta water before draining.
05 - Add the drained gnocchi to the skillet with the bacon fat. Toss over low heat to coat evenly.
06 - Remove the skillet from heat. Quickly pour the egg and Parmesan mixture over the gnocchi, tossing constantly to create a creamy sauce. Add reserved pasta water 1 tablespoon at a time if needed to reach desired consistency.
07 - Taste and adjust seasoning with salt and pepper as needed. Serve immediately, garnished with extra Parmesan and chopped parsley if desired.
