To make simple carbonara sauce, you need cooked pasta, eggs, Parmesan cheese, bacon or pancetta, and seasoning. The basic process is:
- Cook spaghetti according to package instructions and reserve some pasta water before draining.
- Cook diced bacon or pancetta in a pan until crispy.
- Whisk eggs with grated Parmesan cheese, salt, and pepper until smooth.
- Add cooked pasta into the pan with bacon off the heat, then quickly toss in the egg and cheese mixture while stirring continuously to create a creamy sauce.
- Add reserved pasta water gradually as needed to loosen the sauce to a smooth consistency.
- Serve immediately with extra Parmesan and pepper on top.
No cream is needed; the sauce is creamy from the eggs and cheese alone. Using room temperature eggs helps achieve a better texture. The key is to toss the pasta and egg mixture off the heat to prevent scrambling and form a silky sauce.
