1Bring a large pot of aggressively salted water to a boil and cook spaghetti until al dente.
2Reserve 1 1/2 cups of the starchy pasta water, then drain the spaghetti.
3While the pasta cooks, heat the olive oil gently in a large skillet over medium-low heat.
4Add the garlic slices and whole parsley stem to the skillet.
5Stir constantly until the garlic turns light golden (about 3 minutes).
6Stir in the chili flakes and a pinch of salt.
7Let them bloom for 30 seconds, then remove the parsley stem and take the pan off the heat.
8Add about ½ cup of the reserved pasta water to the skillet and stir/whisk vigorously to combine with the oil to form an emulsion.
9Return the pan to medium-low heat and add the drained spaghetti along with another splash of pasta water.
10Toss everything aggressively with tongs for 1–2 minutes, drizzling in 1 to 2 more tablespoons of olive oil and a bit more pasta water as you go, alternating between the two while tossing nonstop until the sauce turns silky and glossy.
11Turn off the heat and stir in the chopped parsley.
12Taste and add a tiny pinch of salt if needed.
13Plate immediately, spooning any extra sauce from the pan over the top.
14Garnish with lemon zest and a sprinkle of Parmesan.
