An aromatic, vibrant and fresh pasta sauce, pesto originated in the early 1600s, in Genoa, a port city in Northwestern Italy. Authentic Genovese pesto calls for just 7 high quality ingredients – fresh basil, extra virgin olive oil, pine nuts, garlic, salt, Parmesan and Pecorino cheeses. The key to a really good pesto is how the ingredients are combined together, and this Pesto Genovese is, well, simply divine.

Origins of this Pesto Genovese recipe

This particular basil pesto recipe came to me from Chef Paolo Laboa at Solo Italiano restaurant in Portland, Maine. While on a bike trip in Maine, Robert, our friends and I enjoyed a fabulous meal at Solo Italiano. I ordered a pasta dish featuring their “authentic Genovese pesto.”

I’m here to tell you, it was the smoothest, most well balanced pesto I’d ever eaten – and I’ve had a lot over the years. The texture was so silky. Not too garlicy, not too cheesy, not too oily. I was fascinated. So, channeling my mother, I walked into the kitchen and asked to speak to the chef. Chef Paolo couldn’t have been nicer – or more proud of his Pesto Genovese. He said it was an old family recipe that had won several awards in Genoa, where he was born and raised. He graciously offered me the recipe. I was thrilled!

Secrets to making a silky smooth pesto

According to chef, the secrets to this Pesto Genovese’s clean, smooth texture are:

  • soaking the basil leaves in cold water, and leaving a bit of water on them,
  • using finely grated cheeses,
  • following his unique, step-by-step blending process (he’s okay with using a blender or food processor, rather than the traditional mortar and pestle),
  • pulsing rather than constant processing, so the sauce doesn’t heat up and cause the oil to separate, and
  • stirring 1 tablespoon of hot pasta water into the pesto and letting it sit for a few minutes before serving, to melt the cheeses.

How should you store homemade pesto?

Pesto should be spooned into a bowl or jar with a thin layer of olive oil placed on top, covered and refrigerated. It can also be frozen (see below).

How long does homemade pesto last?

While refrigerated pesto will last for up to 2 weeks, I think its flavor is best within a week. Make sure to put a thin layer of olive oil directly on top of the pesto and store it in an airtight container.

Can you freeze pesto?

Yes, it can be frozen and thawed in the refrigerator. As with refrigeration, make sure to put a thin layer of olive oil directly on top of the pesto and store it in an airtight container. It will last for up to 3 months.

How much pesto should you add to pasta?

This is a really difficult question to answer. For 1 pound of pasta, I’ve seen recommendations for anywhere from 3 tablespoons to 1 cup of pesto! It’s really to taste. I usually use around 1/3 to 1/2 cup pesto per 1 pound of pasta. If you accidentally add too much pesto, just add in a bit more pasta water.

Description

This well balanced and smooth Pesto Genovese is worth a try. It’s an award-winning family recipe direct from an Italian chef raised in Genoa, and relies on a unique preparation method to ensure it comes out scrumptious, vibrant and silky.


Scale

Ingredients

  • 4 cups fresh basil leaves (stems removed), loosely packed
  • 1/3 cup toasted pine nuts
  • 1/2 cup extra virgin olive oil
  • 1/2 teaspoon chopped garlic (1 clove)
  • 1 teaspoon kosher salt
  • 1/3 cup finely grated Parmesan cheese
  • 1/3 cup finely grated pecorino Romano cheese

Instructions

  1. Soak basil leaves in cold water for 1 hour.
  2. Place pine nuts, olive oil and garlic in a small blender or food processor. Pulse until mixture is a coarse paste.
  3. Shake most, but not all, of the water off 1 cup of the basil leaves. Add to blender and pulse a few times. Repeat with remaining basil leaves, adding 1 cup at a time. Process, pulsing, until puréed and smooth.
  4. Add salt and pulse until smooth. Add the cheeses and pulse just until blended. Do not over blend, as the sauce can separate.
  5. Place pesto in a small bowl or jar. If preparing more than 30 minutes ahead, cover with a thin layer of olive oil.

Notes

When serving: add 1 tablespoon hot pasta water to the sauce and let it sit for a few minutes, to melt the cheeses and make it silkier.

Make ahead: pesto can be prepared, a thin layer of oil added to the top, covered and refrigerated for up to 2 weeks. Can also be frozen up to 3 months.
