01 - Bring a large pot of salted water to a boil. Cook the pasta until al dente following package directions. Reserve ½ cup of pasta water, then drain.
02 - Heat olive oil in a large skillet over medium heat. Add beef bacon strips and cook until crispy and golden, about 5 to 7 minutes. Remove from heat, leaving the bacon and rendered fat in the pan.
03 - Whisk together egg yolks, whole egg, heavy cream, Parmesan cheese, black pepper, and sea salt until smooth.
04 - Add drained pasta to the skillet with beef bacon and toss to coat evenly in the bacon fat.
05 - Remove skillet from heat. Immediately pour the egg and cream mixture over the pasta, tossing quickly to coat. Gradually add reserved pasta water, tossing continuously until a creamy sauce forms and adheres to the pasta.
06 - Plate the pasta and garnish with extra Parmesan cheese and chopped fresh parsley if desired. Serve immediately.
