In a large skillet, heat the butter and olive oil over medium-high heat. Add the gnocchi in a single layer and cook for 5 to 6 minutes, stirring frequently, until golden and crisp.
Reduce the heat to medium. Add the wine and deglaze the pan with a wooden spoon. Simmer until the wine has almost evaporated.
Reduce the heat to medium-low and add the cream to the skillet. Allow it to simmer for about 1 minute, then remove it from the heat and stir in the pesto. Taste and season with salt, as desired.
Serve warm with Parmesan cheese, if desired.
Notes
Substitutions:
Heavy Cream: You can substitute the heavy cream for half and half. I do not recommend using plain milk as the sauce will not thicken.
Gnocchi: Use your favorite store-bought gnocchi. If you use frozen gnocchi, be sure to cook it slightly longer over low heat.
White Wine: Substitute the wine for vegetable or chicken broth.
Pesto Sauce: Using homemade pesto sauce will really enhance the flavor of this recipe. If you use store-bought, use fresh pesto sauce from the refrigerated section for the best flavor. If you want a richer pesto flavor, add more pesto sauce to this dish.
Thinner sauce: Add more chicken broth to thin the sauce.
Storage:Store leftovers in an airtight container in the refrigerator for up to 3 days. I do not recommend freezing any pasta made with cream sauce as it separates.
