Combine 1/2 cup of toasted walnuts, minced garlic, 1/2 cup fresh Parmesan cheese, basil leaves, parsley, olive oil and juice from half a lemon in a food processor or blender. Season with ½ teaspoon salt and ¼ teaspoon black pepper.
Pulse continuously until all ingredients are broken down and well combined, 1-2 minutes. Scrape the sides of the bowl at least once to ensure all ingredients are evenly mixed in. Taste and adjust salt and pepper as desired.
Toss pesto with hot, cooked pasta to coat and heat through. Eight ounces of pasta and this pesto recipe will provide about 4 servings.
Divide into bowls and top with fresh basil, Parmesan and the remaining toasted walnuts. Serve with lemon wedges on the side.
Notes
To toast walnuts: Heat oven to 350 degrees. Arrange walnuts in a single layer on a small baking sheet lined with parchment paper or a silicone mat. Toast in the oven for about 5-7 minutes, stirring occasionally to prevent burning. OR heat a skillet over medium heat and toast the walnuts in the hot skillet, shaking often to avoid burning.
