Bring a large pot of salted water to a boil. Throw in your spaghetti and cook until al dente. Before draining, scoop out a cup of pasta water and set it aside.
While pasta’s doing its thing, heat olive oil in a large pan over medium heat. Toss in diced pancetta and cook until golden and crispy on the edges.
Add minced garlic to the pan with pancetta. Sauté for about a minute, then pull the pan off the heat.
In a separate bowl, whisk together the eggs, grated Parmesan, and a good amount of freshly ground black pepper.
Return the pancetta pan to low heat. Add the drained pasta and toss to coat the noodles in flavorful fat.
Remove pan from heat to avoid scrambling. Stir in egg and cheese mix, adding reserved pasta water gradually for creamy sauce.
Season with salt and pepper. Serve immediately with extra Parmesan on top.
Notes
Add peas or spinach at the end for a veggie touch. Use Pecorino Romano if out of Parmesan. Store leftovers up to 3 days refrigerated.
