Classic Basil Pesto Pasta

1.Bring a large pot of salted water to a boil. Add the pasta and cook until al dente according to package instructions, usually 8-10 minutes. Reserve 1/2 cup of pasta cooking water, then drain the pasta.

2.While the pasta cooks, prepare the pesto: In a food processor or blender, combine basil leaves, garlic, pine nuts, Parmesan, salt, and pepper. Pulse until finely chopped.

3.With the processor running, slowly drizzle in the olive oil until the mixture becomes a smooth, vibrant green sauce. Scrape down the sides as needed. Taste and adjust seasoning if necessary.

4.Transfer the drained pasta to a large bowl. Add the pesto and toss to coat, adding a splash of reserved pasta water as needed to create a silky sauce that clings to the pasta. For extra richness, stir in the butter until melted and incorporated.

5.Serve immediately, garnished with extra Parmesan cheese and a drizzle of olive oil. Optionally, top with a few fresh basil leaves and a sprinkle of toasted pine nuts for added texture.
