Follow these steps to create your Creamy Bacon Carbonara Pasta perfectly:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add spaghetti or fettuccine and cook according to package instructions until al dente. Reserve about 1 cup of pasta cooking water, then drain the pasta.

2. Cook the Bacon: In a large skillet over medium heat, add the diced bacon or pancetta. Cook until crispy, about 5-7 minutes. If using, add minced garlic in the last minute of cooking and sauté until fragrant.

3. Prepare the Sauce: In a medium bowl, whisk together the eggs and grated Parmesan cheese until well combined. Season with a pinch of salt and freshly ground black pepper.

4. Combine Ingredients: Add the drained pasta into the skillet with the cooked bacon. Remove the skillet from heat, and quickly pour the egg and cheese mixture over the hot pasta, tossing continuously to create a creamy sauce. If the pasta seems too dry, add a little reserved pasta water until you reach the desired consistency.

5. Adjust Seasoning: Taste and adjust the seasoning with additional salt and pepper if needed.

6. Serve: Remove from heat, and let the pasta sit for a minute to allow the sauce to tighten. Garnish with fresh parsley and extra Parmesan cheese if desired.
