Prepare the Pesto: In a food processor, combine the packed basil leaves, peeled garlic cloves, toasted pine nuts, and freshly grated Parmesan cheese. Pulse the mixture until it is finely chopped and well combined.
Blend in Olive Oil: With the food processor running, slowly drizzle in the extra virgin olive oil. Continue blending until the pesto reaches a smooth and creamy consistency. Taste and season with salt and freshly ground black pepper as desired. Set the pesto aside for later use.
Cook the Gnocchi: Bring a large pot of salted water to a rolling boil. Add the potato gnocchi to the pot and cook according to package instructions, usually about 2-3 minutes. They are ready when they float to the surface.
Make the Cream Sauce: In a large skillet set over medium heat, pour in the heavy cream. Add the prepared pesto and stir well to combine. Allow the mixture to heat through for about 2-3 minutes, stirring occasionally until creamy and warmed.
Combine Gnocchi and Sauce: Once the gnocchi are cooked, use a slotted spoon to transfer them directly into the skillet containing the creamy pesto sauce. Gently toss the gnocchi to coat them evenly in the sauce, taking care not to break them apart.
Adjust Consistency: If you find that the sauce is too thick, add a splash of the starchy pasta water (which you reserved from cooking the gnocchi) until you achieve your desired consistency.
Serve: Transfer the creamy pesto gnocchi to serving plates and garnish with halved cherry tomatoes for a colorful touch and a fresh burst of flavor.
Notes
Add cherry tomatoes for garnish to enhance flavor and presentation.
