Method
Step-by-Step
- Bring a large pot of generously salted water to a boil. Cook the pasta until al dente according to the package directions, then reserve at least 1 cup of the cooking water before draining.
- While the pasta cooks, melt the butter with the olive oil in a large skillet over medium-low heat. Add the minced garlic and cook for 30 to 60 seconds, just until fragrant, without allowing it to brown.
- Add the drained pasta to the skillet and toss until each strand is coated with the warm butter and oil. Remove the skillet from the heat before adding the cheese.
- Add the Parmesan, parsley, kosher salt, and black pepper. Toss vigorously while adding reserved pasta water a few tablespoons at a time until the cheese melts into a light, glossy sauce.
- Taste the pasta and adjust the seasoning. Add red pepper flakes or lemon juice or zest if desired, then serve immediately with more Parmesan and parsley.
Notes
Freshly grated Parmesan melts more smoothly than pre-shredded cheese. Add the cheese off the heat and use starchy pasta water gradually so the sauce stays creamy rather than watery. For an all-butter version, use 4 tablespoons butter instead of butter and olive oil.
