Cook pasta according to package directions. Reserve 1 cup of pasta water and drain.
Puree the basil, garlic, parmesan cheese, pine nuts, olive oil, salt and pepper in a blender or food processor until smooth.
Add pesto sauce to a large pot or skillet over medium-low heat. Stir in the tomato paste and cream and simmer until thickened, about 5-10 minutes. Use reserved pasta water to thin the sauce, if desired.
Add cooked pasta back into the skillet and toss to combine. Garnish with additional Parmesan cheese and fresh basil.
