10 slices bacon , cut into 1/2-inch pieces
8 1/2 cups water , divided
4 cloves garlic , minced
1 lb spaghetti or linguine
1 1/4 cups finely grated parmesan cheese , plus more for serving (2 oz)
3 large eggs
1 large egg yolk
1 tsp each salt and pepper , or to taste
Chopped fresh parsley , for garnish
Add bacon and 1/2 cup of the water to a large non-stick skillet and bring to a simmer over medium-high heat.

Pour into a medium mixing bowl then add 1 Tbsp rendered bacon fat (drippings in bowl set under strainer) to mixing bowl with garlic. Add eggs, egg yolk, parmesan and pepper to garlic mixture and whisk until well combined.

Carefully drain al dente pasta into colander in bowl, while reserving pasta water in bowl. Measure out 1 cup hot pasta water and discard remaining water. Immediately place pasta in now empty large bowl.
Slowly pour and whisk 1/2 cup pasta water into egg mixture, then slowly pour mixture over pasta while tossing to coat. Add bacon and toss to combine. Season with salt if desired.
