Cook pasta according to the pack instructions. While the pasta is boiling, prep the bacon. Lightly grease a pan with olive oil, add the chopped bacon and cook until soft. Remove any excess bacon fat from the pan, reserving 1 tbsp to be used later.
Add the chopped garlic and cook for 2-3 minutes. By now, the bacon would also be crispy.
Drain the pasta water into a large bowl which you will use to mix the pasta together. This will make sure the bowl is warm but not enough to scramble or curdle the eggs.
Crack the egg in a bowl, whisk well. Add the parmesan,salt and pepper and reserved bacon fat. Mix well until the mixture comes together.
Add the drained pasta to the pan and toss well. Drain the pasta water from the bowl and wipe it dry.
Transfer the pasta to the bowl. Add the egg mixture and toss well until the pasta comes together.
Top with some more pepper and parmesan and serve!
