Bring water to a boil in a large pot. Add a very generous amount of kosher salt; at least 3 tbsp. Drop in the pasta and set a timer for 5 minutes.

Add half the Sizzle to a large cold pan with the garlic and red chili flakes. Heat over a low-medium flame, shaking the pan occasionally. You want the garlic to get a light golden brown color and gentle bubbles in the oil, but not too much.

When the 5 minutes are up, add the rest of the Sizzle to your garlic and red pepper flakes. Either use tongs to transfer the pasta directly to the pan with the garlic and oil, or save at least 1 cup of pasta water BEFORE draining the spaghetti and adding it.

Add about ¼ cup of pasta water (you can eyeball it), and mix the spaghetti into the mixture energetically. Keep cooking the pasta in the pan for 4 to 5 more minutes until it is al dente. Add a few more dashes of pasta water if the pan looks dry.

Add the parsley, grate some parm, squeeze on some Drizzle, and serve.
