• Ingredients
  1. 1/2 cup plus 3 tablespoons extra-virgin olive oil
  2. 1 dried spicy red chile
  3. 1 small dried chipotle chile
  4. 4 Szechuan peppercorns
  5. 3 black peppercorns, cracked
  6. 2 large garlic cloves, minced
  7. 1 medium sweet onion, such as Vidalia, finely chopped
  8. 3 large tomatoes, finely chopped
  9. 1 serrano or large jalapeño, very thinly sliced crosswise
  10. 1 teaspoon thyme leaves
  11. Scant 1 teaspoon minced oregano
  12. Salt and freshly ground pepper
  13. 1 pound dried egg fettuccine
  14. 1/2 cup coarsely chopped basil
  15. 1/4 cup freshly grated Parmesan cheese, plus more for serving

Directions

1. In a small saucepan, combine 1/2 cup of the olive oil with the dried red chile, the chipotle, Szechuan peppercorns and black peppercorns and bring to a simmer. Cook over very low heat for 15 minutes, then strain the hot chili oil into a jar.
2. In a large, deep skillet, heat the remaining 3 tablespoons of olive oil until shimmering. Add the garlic and cook over moderate heat, stirring, until fragrant but not browned, about 30 seconds. Add the onion and cook, stirring frequently, until softened, about 5 minutes. Add the tomatoes, serrano, thyme and oregano, season with salt and pepper and bring to a simmer. Cook the tomato sauce over moderate heat until slightly thickened, about 5 minutes.
3. Meanwhile, in a large pot of boiling salted water, cook the pasta until al dente. Drain the pasta, shake it dry and return it to the pot. Add the tomato sauce, basil, Parmesan and 1/4 cup of the hot chili oil and toss. Serve the pasta in bowls and pass Parmesan and the remaining hot chili oil at the table.
