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