- Heat broiler. Cook the pasta according to the package directions; drain and return it to the pot.

- Warm the oil with the garlic and red pepper in a small saucepan over medium heat until fragrant, 1 to 2 minutes.
- Add the garlic oil, basil, ½ teaspoon salt, and ¼ teaspoon black pepper to the pasta and toss to combine. Serve topped with the tomatoes, additional basil, and shaved Parmesan.
