- Walnut Pesto
- 3 1/2 cups California walnuts, toasted
- 4 cups Italian parsley leaves, packed
- 2 cups Parmigiano Reggiano cheese, freshly grated
- 1 1/2 cups garlic cloves 4 extra virgin olive oil
- Salt and pepper fresh
- 4 lb pappardelle pasta
- 1 1/2 cups California walnuts, toasted, chopped
- Parmigiano Reggiano cheese (optional)
- Place half of the walnuts, parsley, cheese and garlic in food processor; process until finely chopped.
- With motor running, slowly pour in half of the oil; purée until smooth. Transfer to bowl and repeat with remaining ingredients, making a total of 2 batches. Season with salt and pepper; set aside. (Makes approx. 4 cups).
- Cook pasta in boiling salted water until al dente, about 3 to 4 minutes. Drain, reserving some of the cooking water. For each serving, toss 2 cups cooked pasta with 1/4 cup Walnut Pesto adding some of the reserved cooking water as required to thin the pesto; toss well to coat evenly.
- Transfer to warm pasta bowl; sprinkle with 1 tbsp chopped walnuts and shaved or grated cheese, as desired. Serve immediately.
