Step 1

Heat a large pot over medium heat; add the oil and butter. Allow the butter to foam, then add the garlic and red pepper flakes. Cook until fragrant, 1 minute.

Step 2

Add the pasta, 6 cups of water, and salt to the pot and bring to a simmer. Reduce the heat to medium-low and continue simmering for 8 to 10 minutes, stirring frequently to prevent sticking, until the pasta is al dente.

Step 3

Remove from the heat and stir in the parmesan, lemon zest, lemon juice, and basil. Serve topped with more parmesan, basil, and black pepper.
