Boil the Ramen: Cook your 2 packs of ramen noodles according to the packet instructions. Before you drain them, scoop out 1½ cups of the ramen cooking water and set it aside — you'll need ½ cup for the sauce and the remaining 1 cup for the pan. Drain the noodles.
Make the Carbonara Sauce: While the noodles are cooking, grab a small bowl and whisk together the 2 egg yolks, ⅓ cup freshly grated parmesan, and both ramen seasoning packets. Pour in the ½ cup reserved ramen water and mix until smooth and combined. It will look like a thick, golden paste — that's exactly what you want. (WATCH VIDEO BELOW — sauce consistency)
Fry the Guanciale: In a large frying pan or skillet over medium-high heat, cook your 1 cup of diced guanciale (or bacon) until crispy and golden. This takes about 4–5 minutes. Don't drain the fat — that's your flavor base.
Add the Noodles and Sauce: Take the pan off the heat (this is the most important step — residual heat only, or you'll scramble the eggs). Add the drained ramen noodles to the pan with the crispy guanciale. Pour in the carbonara sauce and toss everything together quickly. Add the remaining 1 cup of ramen water gradually as you mix, until the sauce is glossy and silky and coats the noodles.
Serve Immediately: Plate it up, top with extra parmesan and a crack of black pepper, and eat right away. Carbonara waits for no one — serve it fresh!
