- 2 cups (50g) fresh basil leaves (preferably young, small leaves from Genoa or similar varieties)
- 2 cloves garlic, peeled
- ¼ cup (30g) pine nuts
- ½ cup (50g) grated Parmigiano Reggiano cheese
- ¼ cup (25g) grated Pecorino Sardo cheese (or Pecorino Romano if Sardo is unavailable)

- 1 teaspoon coarse sea salt (adjust to taste)
For Serving:
- 12 oz (340g) trofie, trenette, or linguine pasta
- 1 small potato, peeled and diced (optional, traditional in Liguria)
- 1 cup (150g) green beans, trimmed and cut into 2-inch pieces (optional, traditional)
- Extra grated Parmigiano Reggiano for garnish
Equipment Needed
- Mortar and pestle (traditional) or food processor (for a quicker method)
- Large pot (for boiling pasta)
- Colander
- Measuring cups and spoons
- Grater (for cheese)
- Small skillet (for toasting pine nuts)
- Mixing bowl (if using a food processor)
Step-by-Step Instructions
Step 1: Prepare the Ingredients
Start by washing 2 cups of fresh basil leaves in cold water to preserve their vibrant green color. Gently pat them dry with a clean kitchen towel or paper towels—avoid bruising the leaves, as this can cause them to oxidize and darken. Peel 2 garlic cloves and set aside. Measure out ¼ cup pine nuts, ½ cup grated Parmigiano Reggiano, and ¼ cup grated Pecorino Sardo. Using both cheeses is traditional for a balanced flavor—Parmigiano adds nutty depth, while Pecorino brings a sharp, salty bite. If Pecorino Sardo is unavailable, Pecorino Romano is a fine substitute.
Step 2: Toast the Pine Nuts
In a small skillet over medium-low heat, lightly toast ¼ cup pine nuts for 2-3 minutes, stirring frequently, until they turn golden and release a nutty aroma. Be careful not to burn them, as this can make the pesto bitter. Toasting enhances the pine nuts’ flavor, giving the pesto a richer taste. Once toasted, set them aside to cool slightly.
Step 3: Make the Pesto (Traditional Mortar and Pestle Method)
In a mortar, add 2 garlic cloves and 1 teaspoon coarse sea salt. Grind them into a smooth paste using the pestle—this helps mellow the garlic’s sharpness. Add the toasted pine nuts and crush them into a fine paste, blending them with the garlic. Next, add the basil leaves in small batches, grinding them with a circular motion until they break down into a creamy, green paste. The salt helps break down the leaves while preserving their color. Once the basil is fully incorporated, stir in ½ cup grated Parmigiano Reggiano and ¼ cup grated Pecorino Sardo, mixing until combined. Gradually drizzle in ½ cup extra virgin olive oil, stirring continuously, until the pesto reaches a smooth, slightly loose consistency. Taste and adjust seasoning if needed, but be cautious with salt due to the cheeses.
Step 3 Alternative: Make the Pesto (Food Processor Method)
If you’re short on time, a food processor works well, though it may slightly alter the texture. Add 2 garlic cloves, 1 teaspoon coarse sea salt, and ¼ cup toasted pine nuts to the processor and pulse until finely chopped. Add 2 cups basil leaves and pulse again until a coarse paste forms—avoid over-processing to prevent the basil from turning dark or bitter. Add ½ cup grated Parmigiano Reggiano and ¼ cup grated Pecorino Sardo, pulsing to combine. With the processor running on low, slowly drizzle in ½ cup extra virgin olive oil until the pesto is smooth but not overly emulsified. Scrape down the sides as needed. Taste and adjust seasoning, ensuring the pesto remains vibrant and balanced.
Step 4: Cook the Pasta (Traditional Ligurian Style with Potato and Green Beans)
Bring a large pot of salted water to a boil. If following the traditional Ligurian method, add 1 small diced potato to the boiling water and cook for 5 minutes. Then add 1 cup trimmed green beans and cook for another 3 minutes. Finally, add 12 oz trofie, trenette, or linguine to the same pot and cook according to package instructions, typically 8-10 minutes, until al dente. The potato and green beans should be tender but not mushy by the time the pasta is done. This method infuses the pasta with subtle flavors and adds texture to the dish. Reserve 1 cup of the starchy cooking water, then drain the pasta, potato, and green beans together.
Step 5: Combine Pasta and Pesto
In a large mixing bowl, add a few tablespoons of the reserved pasta water to the pesto to loosen it slightly—this helps it coat the pasta evenly. Add the drained pasta (and potato and green beans, if using) to the bowl with the pesto, tossing gently to coat. If the mixture is too thick, add more pasta water, a tablespoon at a time, until the pesto clings to the pasta in a light, creamy layer. The starch from the pasta water helps bind the sauce without overpowering the fresh flavors.
Step 6: Serve Immediately
Divide the Pesto alla Genovese among warmed plates or shallow bowls to maintain its vibrant texture. Garnish with a sprinkle of extra grated Parmigiano Reggiano for added richness. Serve immediately, enjoying the bright, herbaceous aroma of the basil and the nutty, garlicky undertones in every bite. If you skipped the potato and green beans, the dish is just as delicious with the pasta alone, highlighting the pesto’s bold flavors.
Tips for Success
- Basil Quality: Use the freshest basil possible, ideally small, tender leaves from a Genovese variety. Avoid wilted or large, tough leaves, as they can be bitter.
- Olive Oil: Choose a mild, fruity extra virgin olive oil, preferably from Liguria, to complement the basil without overpowering it.
- Prevent Oxidation: If using a food processor, work quickly and keep the pesto covered to minimize air exposure, which can darken the basil.
- Cheese Balance: Stick to the Parmigiano-Pecorino ratio for authenticity. Using only one cheese can throw off the flavor profile.
- Storage: Store leftover pesto in an airtight container in the fridge for up to 3 days, with a thin layer of olive oil on top to prevent oxidation. Alternatively, freeze in ice cube trays for up to 3 months.

Cultural Significance
Pesto alla Genovese originates from Genoa, the capital of Liguria, with roots dating back to the Middle Ages. The name “pesto” comes from the Italian word pestare, meaning to pound or crush, reflecting the traditional mortar-and-pestle method. It evolved from a medieval garlic-based sauce called agliata, with basil becoming the star ingredient by the 19th century due to Liguria’s abundant basil crops. Today, it’s a symbol of Ligurian cuisine, often served with trofie pasta and celebrated at the biennial Pesto World Championship in Genoa. The dish embodies the region’s focus on fresh, aromatic ingredients, showcasing the simplicity and elegance of Italian cooking.
