You only need a handful of simple ingredients for this creamy pesto sauce, and it’s ready in about 20 minutes. It’s perfect for a quick dinner when you’re craving pasta.


  • 8 ounces fettuccine
  • 8 tablespoons unsalted butter
  • 1/2 cup heavy cream
  • 1/4 cup pesto
  • 1 teaspoon lemon zest
  • 1/4 cup grated Parmesan cheese
  • 2 tablespoon chopped parsley
  • Juice of a half lemon
  • Salt, to taste


  1. Boil the pasta according to package instructions.
  2. While the pasta cooks, melt the butter over medium heat in a large pan. Add the cream and whisk the two together.
  3. Add the pesto and lemon zest and whisk to combine. Cook the sauce (don’t let it boil) for a couple of minutes before adding the Parmesan cheese and parsley. Stir until the cheese melts into the sauce.
  4. Add the cooked pasta and toss to coat it in the sauce. Squeeze the lemon juice over the top, toss again, and serve.


Pesto: Use your favorite homemade pesto or store-bought to make it really easy.

Salt: I don’t add salt because the cheese and pesto have plenty, but you might want to add more once the sauce is made. Give it a taste before you add the pasta.

Protein: Add cooked shrimp or chicken at the end to make it more filling.
