Add the guanciale to a large skillet and cook over medium heat for about 10 minutes until crispy and golden. Be patient to allow the guanciale to fully render in its fat for maximum flavor. Transfer the crispy guanciale to a plate, leaving about 2 tablespoons of fat in the skillet.
02 -
While the guanciale renders, bring a large pot of generously salted water to a boil. Add the rigatoni and cook until al dente, about one minute less than package directions. Reserve 2 cups of the starchy pasta water before draining.
03 -
Add the freshly ground black pepper to the rendered guanciale fat and cook for about a minute. Pour in 1 cup of the reserved pasta water, turn heat to high, and boil until reduced by half.
04 -
Add the cooked rigatoni to the skillet. Toss thoroughly with the rendered fat and reduced pasta water mixture using a wooden spoon, adding more reserved pasta water if necessary until pasta is well-coated.
05 -
Stir half of the finely grated Pecorino Romano cheese into the pasta until fully incorporated. The sauce should appear creamy and glossy.
06 -
Add the crispy guanciale back into the pasta and toss to combine evenly.

Garnish with the remaining Pecorino cheese and additional freshly ground black pepper. Serve immediately while hot.
