Arugula pesto is a flavorful sauce that adds a unique twist to many types of pasta, from spaghetti and tagliatelle to rigatoni and even gnocchi.Unlike the classic basil pesto, arugula pesto has a slightly bitter taste, which comes from the arugula (also known as rocket). However, the bitterness is balanced beautifully by the rich, nutty flavor of walnuts.
Place the walnuts in a dry pan over medium heat. Let them toast for about 2 minutes, stirring occasionally to make sure they don't burn.
Once toasted, transfer the walnuts to a blender or food processor.
Add the Parmigiano-Reggiano and Pecorino cheeses to the blender. Also, toss in a peeled garlic clove.
Pour in half of the olive oil to start. Blend the mixture on high speed for about 2 to 3 minutes.
Add the arugula salad. To keep the arugula’s vibrant green color, add a couple of ice cubes to the blender.
Blend everything together on high speed for about 5 minutes, or until the pesto is creamy and smooth. As you blend, slowly drizzle in the remaining olive oil.
Once your arugula pesto is ready, transfer it to a small bowl. This pesto is perfect for tossing with your favorite pasta. When mixing the pesto with pasta, you may need to add a little bit of the pasta cooking water to help the pesto coat the pasta evenly. You can also drizzle in some extra olive oil for a smoother texture.
