Boil water in a large saucepan. When it starts to simmer, add a small handful of salt.
salt
If you haven't done so already, grate your cheese. Set ⅓ of it aside.
2 oz parmesan
In a bowl or jug, whisk the egg yolks, egg, remaining parmesan and some black pepper together. Set aside.
2 large egg yolks, 1 large whole egg, pepper
In a dutch oven or in a large frying pan, heat the oil over medium heat. Add the pancetta and cook until crispy and golden brown. Remove from the heat.
2 tablespoons olive oil, 4 oz guanciale
Cook the gnocchi in the boiling water according to package instructions, once it is almost done scoop out 1 cup of water and set aside. Scoop the gnocchi out with a slotted spoon or drain.
1 lb gnocchi
Return back to the dutch oven, add ¼ cup of the water and bring to a boil over medium heat. Add the gnocchi and boil for 1 minute, then turn the heat off again. Let the dutch oven cool for a couple of minutes.
Whisk ⅛ cup of water to the egg mixture. Slowly pour this into the dutch oven, stirring constantly. You should have a thick sauce. Feel free to add more water if it isn't the consistency you like!
Divide into bowls and top with the reserved cheese and some cracked black pepper.
Notes
Parmesan: I recommend grating it yourself rather than buying pre-shredded parmesan. You can swap it out for pecorino.Guanciale: swap this out for pancetta or bacon bits. Storage: I don't recommend storing this in the fridge and it's best enjoyed right away.
