Pesto Genovese is an Italian classic that celebrates fresh summer basil. It’s the ideal way to use a bounty of basil while creating a bright, flavorful sauce. Below are clear tips and a straightforward method for making traditional basil pesto with a food processor. For a similar summery condiment, try a peach chutney when peaches are in season.

Why This Recipe is a Keeper!

While you can make pesto from many greens, Pesto Genovese made with fresh basil is the quintessential version. The classic recipe balances basil leaves, pine nuts, two cheeses, garlic, and extra-virgin olive oil to create a smooth, emulsified sauce.

Traditionally pesto is made in a mortar and pestle, but a food processor delivers an effortless, creamy result in much less time. Use it tossed with pasta, spread on crusty bread, stirred into soups, or layered in lasagna for an instant flavor boost.

This classic basil pesto is:

  • Easy — made quickly in a food processor.
  • Balanced and flavorful — the cheeses, nuts, garlic, and basil should sing together.
  • Versatile — great on pasta, sandwiches, roasted vegetables, or stirred into soups and sauces.
  • Freezer-friendly — freeze portions to enjoy the taste of summer year-round.

What is Pesto Genovese?

Pesto Genovese is a raw herb sauce built around fresh basil and a few potent ingredients: olive oil, cheese, garlic, and pine nuts. The name “pesto” comes from the Genoese verb “pestare,” meaning “to crush,” a nod to the traditional mortar-and-pestle method. Making it with minimal, high-quality ingredients yields the bright, aromatic pesto everyone loves.

Below are the components you’ll need. Exact quantities are presented in the recipe section further down.

Ingredient Notes and Substitutions:

  • Basil: Choose fresh, aromatic basil. Basil is delicate and bruises easily; handle gently. If its flavor is too assertive, replace half the basil with spinach or parsley.
  • Parmigiano-Reggiano: This aged Italian cheese adds nutty, savory depth. Domestic Parmesan works if you prefer. For vegetarian or vegan versions, use a rennet-free or plant-based cheese substitute.
  • Pecorino Romano: A salty sheep’s milk cheese traditionally used in pesto. Because it’s quite salty, taste before adding extra salt.
  • Extra-Virgin Olive Oil: A mild extra-virgin olive oil keeps the pesto fresh-tasting; choose one you enjoy.
  • Pine Nuts: Also called pignoli, they lend a buttery richness. Substitute walnuts or almonds to reduce cost or for a different flavor profile.
  • Garlic: Adjust the amount to taste.

Step-By-Step Instructions:

  • Gather and prep all ingredients.
  • Chill the food processor bowl in the freezer for about 30 minutes to help keep the pesto bright green.
  • You’ll need roughly four cups of fresh basil leaves (packed). I usually eyeball it—one good handful is about a cup for me.

  • Wash the basil leaves gently. Submerge stems and leaves briefly in water to dislodge any dirt or insects, then lift them out so sediments remain in the sink or bowl.

  • Strip the leaves from the stems and compost the stems and any flower tips.
  • Wash leaves two or three times and dry them in a salad spinner. Avoid long soaking, which can leach flavor.
  • After spinning, lay the leaves on a clean, lint-free towel to air-dry briefly. Excess water dilutes the oil and can dull the sauce.

  • Combine the basil leaves, pine nuts, garlic, and both cheeses in the chilled food processor bowl—do not add the oil yet.

  • With the processor running, slowly drizzle in the olive oil, as you would when making mayonnaise. This gradual addition helps form a creamy, emulsified pesto.

  • Taste and adjust seasoning with salt, freshly ground black pepper, or additional garlic. If you used Pecorino Romano, you may not need much extra salt.

That’s it — classic basil pesto made right. To serve immediately, toss with drained pasta off the heat and add a splash of reserved pasta cooking water to bind and smooth the sauce.

Chef Tips and Tricks:

  • Keep the food processor bowl cold to preserve the pesto’s bright green color; chilling the bowl in the freezer for 30 minutes helps.
  • Dry the basil thoroughly after washing. Oil and water don’t mix, and excess moisture will thin the sauce and mute the flavor.
