Pesto Sauce Recipe - Once Upon a Chef (1)

One of my favorite things about summer cooking is stepping out my back door to pick fresh herbs from my potted herb garden. It always amazes me how the tiny seedlings I plant in May grow into more herbs than I can possibly use up in August. Right now, my basil plant is overflowing, which means it’s time to make pesto sauce. Pesto, or pesto alla genovese, is a vibrant, garlicky green sauce that originated in Genoa, Italy. It’s traditionally made with a mortar and pestle, but most modern versions call for using a food processor. Pesto is a versatile sauce that can be used on just about everything, from pastas to sandwiches to salads. It freezes well, too.

What You’ll Need To Make Pesto Sauce

Traditional pesto is made with garlic, nuts, salt, basil leaves, Parmigiano-Reggiano, and extra-virgin olive oil. It’s important to use top-quality ingredients, as the flavors really shine through.

For the cheese, be sure to use authentic Parmigiano-Reggianofrom Italy; domestic Parmesan is not the same thing. You can always tell if the cheese is authentic by looking at the rind, which is embossed with the name over and over. If the cheese is already grated, it should be labeled “Parmigiano-Reggiano,” not “Parmesan.”

For the nuts, I use walnuts instead of the more traditional pine nuts for a few reasons. First, I always seem to have walnuts in the house (pine nuts can be very pricey). Second, in recent years an increasing number of people, including me, have fallen prey to a bizarre problem with pine nuts called Pine Mouth Syndrome, a bitter, metallic taste in the mouth that develops a day or two after eating pine nuts. It can last for weeks and make eating or drinking anything veryunpleasant. (You can use pecans or almonds, too.)

Step-by-Step Instructions

How To Store & Freeze Pesto

Use the pesto immediately or store it in a tightly sealed jar or air-tight plastic container, covered with a thin layer of olive oil (this seals out the air and prevents the sauce from oxidizing, which would turn it an ugly brown color). It will keep in the refrigerator for about a week.

Pesto can also be frozen in an airtight container for up to 6 months. I suggest dividing it into the compartments of an ice cube tray and freezing. Once frozen, remove the cubes from the tray and put in a sealable plastic bag or airtight container. You can add the defrosted cubes to summer vegetable soup, pasta salad with pesto, zucchini noodles, pesto pizza, eggs, sandwiches, and baked potatoes.

The Best Basic Pesto

Metric Cup Measures

By Jenn Segal

Homemade pesto sauce is easy to make, and it’s good on just about everything, from pastas to pizzas to salads.

Servings: Makes about 1¼ cups (about 10 servings)

Total Time: 15 Minutes

Ingredients

  • ⅓ cup walnuts
  • 2 large garlic cloves, roughly chopped
  • 2 cups packed fresh basil leaves
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper
  • ⅔ cup extra virgin olive oil
  • ½ cup grated Parmigiano-Reggiano

Instructions

  1. Place the walnuts and garlic in the bowl of a food processor fitted with a steel blade. Process until coarsely chopped, about 10 seconds. Add the basil leaves, salt, and pepper and process until mixture resembles a paste, about 1 minute. With the processor running, slowly pour the olive oil through the feed tube and process until the pesto is thoroughly blended. Add the Parmesan and process a minute more. Use pesto immediately or store in a tightly sealed jar or air-tight plastic container, covered with a thin layer of olive oil (this seals out the air and prevents the pesto from oxidizing, which would turn it an ugly brown color). It will keep in the refrigerator for about a week.
  2. Freezer-Friendly Instructions: Pesto can be frozen in an airtight container for up to 6 months. You can also divide your prepared pesto into the compartments of an ice cube tray and freeze. Once it’s frozen, remove the pesto cubes from the tray and put in a sealable plastic bag or airtight container. You can add the defrosted pesto cubes to soups, pasta dishes, eggs, sandwiches, and potatoes.

Why does my homemade pesto taste bad? ›

The most common reason for pesto tasting bitter is that the olive oil is past its best and has started to turn rancid. If the pesto has been made in a food processor or blender, there's also the possibility that it has turned bitter from the crude, sheering action of the blades.

Why is pesto so expensive? ›

Italian pine nuts are considered the finest in the world and are therefore eye-wateringly expensive. To make cost savings, many big producers source their pine nuts from China. Not a big issue, you might think, but these pine nuts are notorious for leaving a metallic aftertaste for some people, and that can last weeks.
