Step 1

Cook the pasta in a large pot of salted, boiling water for 1 to 2 minutes less than instructed on the package, so the texture is al dente.

Step 2

Meanwhile, stir the cream, pesto and butter together in a small saucepot over medium-high heat until the butter is melted. Bring to a boil, then stir in the Parmesan.

Step 3

Drain the pasta and add to the sauce. Stir until the pasta is completely coated. Top with the tomato, torn basil leaves and extra Parmesan, if desired. Serve.
