Ingredients

The following ingredients have 5 Servings
  • 1/4 cup olive oil
  • 1 medium yellow onion (finely diced)
  • 6 garlic cloves (minced)
  • 1/2 teaspoon crushed red pepper flakes
  • 1 28- ounce can San Marzano tomatoes (puréed in a food processor)
  • Kosher salt
  • Fresh basil
  • 1 box Barilla bucatini or spaghetti
  • 2 tablespoons cubed unsalted butter
  • 1/4 cup finely grated Parmigiano Reggiano or Pecorino Romano

Instruction

  • Heat olive oil in a large skillet over medium-low heat. Add onion and cook, stirring, until soft, about 12 minutes. Add garlic and cook, stirring, for 2-4 minutes. Add crushed red pepper flakes; cook for 1 minute more. Increase heat to medium, add puréed tomatoes and season lightly with kosher salt; cook, stirring occasionally, until sauce thickens slightly and the flavors meld, about 20 minutes. Remove pan from heat, stir in basil, and set aside.
  • Meanwhile, bring water to a boil in a large pot. Season with salt; add pasta and cook, stirring occasionally, until about 2 minutes before tender. Drain pasta, reserving 1/2 cup pasta cooking water.
  • Discard basil and heat skillet over high heat. Stir in reserved pasta water to loosen sauce; bring to a boil. Add pasta and cook, stirring, until sauce coats pasta and pasta is al dente, about 2 minutes. Remove pan from heat; add butter and cheese; toss until cheese melts. Transfer to warm bowls; serve with more cheese and more basil, if desired.
