Cook pasta according to package directions. Drain and set aside.

While pasta is cooking, making your pesto mixture: In a small food processor, combine the basil leaves, lemon zest, ¼ cup grated cheese, salt, pepper, garlic power, and olive oil. Pulse a few times ,then puree into a relatively smooth mixture. Taste, adding additional salt or pepper if desired.

Heat cream in a large skillet over medium heat. Once heated through, stir in the remaining ¼ cup grated cheese and the homemade pesto mixture**.

Stir ingredients and bring sauce to a low simmer, stirring regularly, until sauce has thickened, 3-5 minutes.

Reduce the heat to low, then add the drained, cooked pasta to the skillet.

Stir to coat the pasta and let warm through, then serve immediately with extra grated cheese and basil for garnish if desired.
