Step 1

Heat oil in a large straight-sided skillet over medium. Add pancetta and cook, stirring occasionally, until crisp and lightly browned, about 6 minutes. Using a slotted spoon, transfer pancetta to paper towels to drain. Add shallot, garlic, and red pepper flakes to pan; season with salt. Cook over medium heat, stirring occasionally, until soft and translucent, 2 to 3 minutes. Carefully add red wine; increase heat to medium-high and bring to a boil. Boil 2 minutes.

Step 2

Meanwhile, cook pasta in a large pot of generously salted boiling water for 4 minutes. Drain, reserving 1 cup pasta water. Add pasta to pot with red wine; cook, stirring occasionally, until pasta is bright red and al dente and most of wine has been absorbed, 4 to 6 minutes. Stir in cheese and pancetta. Stir in pasta water as needed to loosen sauce. Serve with more cheese, parsley, and red pepper flakes.
