Ingredients

  • 1 (4.5 pound) whole chicken, giblets removed
  • 1 (24 ounce) jar marinara sauce
  • 6 cups water
  • 2 anchovy fillets
  • 1/2 teaspoon red pepper flakes, or to taste
  • 2 teaspoons salt, plus more to taste
  • 1 (16 ounce) package spaghetti
  • 1/4 cup thinly sliced basil leaves
  • 1/2 cup grated Pecorino Romano cheese
  • 1 tablespoon cold butter (optional)
  • 1 tablespoon grated Pecorino Romano cheese

Method

  • Place chicken in a pot and pour marinara sauce on top. Add water and anchovies. Bring to a simmer, uncovered, over high heat. Reduce heat to medium-low. Cover and simmer, without stirring, for 1 hour and 15 minutes.
  • Transfer chicken to a bowl using tongs. Let cool to the touch.
  • Meanwhile, bring sauce to a simmer over medium-high heat. Cook, skimming off the fat from the surface, until sauce is reduced by at least half, 20 to 35 minutes.
  • Tear off chicken meat by hand and transfer to a bowl, breaking the pieces into your desired size.
  • Add the chicken, red pepper flakes, and salt to the reduced sauce. Cook and stir until chicken is heated through, about 2 minutes. Keep on low heat while you cook the pasta.
  • Bring a large pot of lightly salted water to a boil. Cook spaghetti in the boiling water according to package instructions, reducing time by 1 minute, about 11 minutes. Drain and return to the pot; reduce heat to low.
  • Add the chicken sauce and Pecorino Romano to the pasta. Sprinkle in basil and add butter. Stir until butter melts, about 1 minute. Turn off the heat and add remaining Pecorino Romano cheese. Cover and let sit for 1 minute. Stir and serve.
