Ingredients

makes 1/2 cup

　　2 cups packed fresh flat-leaf parsley leaves

　　3/4 cup grated Pecorino Romano cheese (2 ounces)

　　1 small garlic clove, coarsely chopped

　　1/4 cup extra-virgin olive oil, plus more for storing (optional)

　　Freshly ground pepper

　　

Step 1

In a food processor, finely chop parsley, cheese, and garlic. With the motor running, add oil in a slow, steady stream; season with pepper. Serve immediately, or transfer to an airtight container and cover with a thin layer of oil; refrigerate up to 4 days or freeze up to 3 months.

　　

Freezing Pesto

Step 2

Pesto keeps very well in the freezer, so it’s worth making extra. Freeze it in small airtight containers, covered with a thin layer of olive oil. Defrost in the refrigerator before using.
