What is Pesto Genovese?
Pesto Genovese hails from Liguria, on Italy’s northwest coast. At its heart, it’s a fresh basil purée blended with garlic, pine nuts, cheese, olive oil, salt, and pepper. Traditionally pounded with a mortar and pestle, today’s cooks often make it in a food processor for convenience without compromising flavor. This sauce celebrates the simplest, most aromatic ingredients of summer.

Ingredients for the Perfect Pesto Genovese Pasta
- 1 pound (455g) dried pasta — Any shape. Traditional: trofie. Pictured: gemelli.
- 2 oz (55g) aged parmesan or pecorino romano
- 2–3 garlic cloves
- 1/4 cup (35g) toasted pine nuts
- Heaped 4 cups fresh basil leaves (approx. 3 oz/85g)
- 1/2 cup (120 ml) olive oil (plus more as needed)
- Kosher salt and black pepper, to taste
How to Make Pesto Genovese
Option 1: Using a Food Processor
- Grate the Cheese: Cut the parmesan into chunks and process in the food processor until powdery. Set aside.
- Chop Garlic & Nuts: Pulse garlic a few times. Add pine nuts. Pulse until finely chopped but not paste-like.
- Add Basil & Seasonings: Add 1/2 teaspoon salt, black pepper, and basil leaves. Process until basil is finely chopped.
- Incorporate Oil: With processor running, slowly drizzle in olive oil until mixture is smooth and cohesive.
- Add Cheese: Add 1/4 cup parmesan; pulse just to mix. Taste and adjust salt, ensuring the sauce is well-seasoned for pasta.
Option 2: By Hand
- Grate cheese using a box grater.
- Finely chop garlic and pine nuts together using a knife or mezzaluna.
- Add basil leaves and chop until minced.
- Scrape ingredients into a bowl. Season with salt and pepper, drizzle in olive oil, and stir until well combined.
- Mix in the cheese. Adjust seasoning to taste.
Note: The food processor method creates a creamy, uniform sauce, while the hand-chopped approach brings a chunkier, rustic texture with little flecks of cheese and nuts.
Storage Tips
- Use immediately for the brightest flavor and color.
- Store in an airtight container in the fridge for up to 1 week. Press a layer of plastic wrap or drizzle extra olive oil on top to minimize browning.
Assembling the Pasta with Pesto
- Boil the Pasta in a large pot of well-salted water until al dente. Choose the doneness you prefer, since this dish is not finished over heat with sauce.
- Drain and Cool Slightly: Transfer the pasta to a bowl and allow to cool just enough so the sauce stays bright and fresh—room temperature or slightly warm.
- Mix with Pesto: Add about half of the pesto and stir to coat. Add more, a spoonful at a time, to reach your desired level of saucing. Loosen with a drizzle of olive oil if needed.
- Finish and Serve: Top with more parmesan and serve immediately, or at room temperature—perfect for hot summer days.
Serving Suggestions and Favorite Mix-Ins
- White Beans: Stir cooked beans into the pasta for extra protein and creamy texture.
- Halved Cherry Tomatoes: Add a burst of color and complementary sweetness.
- Fresh Mozzarella Balls (bocconcini or ciliegine): Creamy and cooling, perfect for balancing the herbal pesto.
- Grilled or Broiled Zucchini/Summer Squash: Slice thin, grill or broil until caramelized, then toss with olive oil, salt, pepper, a splash of red wine vinegar, capers, and serve at room temperature.
- Green Beans & Potatoes: For a Ligurian twist, toss boiled chunks directly with the pasta and pesto.
Tip: Sometimes skipping the pasta entirely in favor of a bowl composed of the above vegetables and cheese with pesto makes a glorious summer salad.
Expert Tips for Perfect Pesto
- Cheese: Use high-quality, aged cheeses like Parmigiano Reggiano or Pecorino Romano for robust flavor.
- Basil: Use the freshest leaves, preferably young and tender, for the most aromatic results.
- Toasting Pine Nuts: Quickly toast pine nuts for deeper flavor but avoid overbrowning to prevent bitterness.
- Oil: Opt for fruity, mild extra-virgin olive oil to enhance rather than overpower the basil.
Keeping Your Pesto Bright Green
Basil pesto is notorious for turning an unappetizing brown if exposed to air or heat for too long. Several strategies help preserve its bright, fresh appearance:
- Minimize Heat and Air Exposure: Avoid overheating the pesto by mixing it with pasta off the heat. Store with a fine layer of olive oil on the surface.
- Blanching Basil Leaves: Briefly dunk basil leaves in boiling water for 10–15 seconds, then transfer to ice water before processing. This sets the green color. Some cooks, however, prefer skipping this step to avoid soggy leaves.
- Lemon Juice: A small squeeze of lemon juice can provide a gentle acid to help preserve color and enhance flavor.
Traditional vs. Modern Pesto: Mortar & Pestle or Food Processor?
The classic Ligurian method calls for pounding ingredients with a heavy mortar and pestle, creating a slightly chunky, multi-textured sauce that some consider superior. However, most home cooks opt for a food processor or blender for speed and convenience. Both options deliver delicious results—choose your method based on time, tools, and desired texture.
Frequently Asked Questions (FAQs)
Q: Can I make pesto ahead of time?
A: Absolutely. Pesto keeps for up to a week in the refrigerator. To prevent browning, press plastic wrap directly against the surface or drizzle an extra layer of olive oil on top before sealing.
Q: My pesto turned brown. What happened?
A: Browning often results from oxidation. Keep exposure to air and heat to a minimum, try blanching basil leaves before blending, or use oil and lemon juice to help preserve color.
Q: Can I substitute nuts or cheese?
A: Yes, for variation or if accommodating allergies. Substitute walnuts, cashews, or even sunflower seeds for pine nuts, and try pecorino or Grana Padano for parmesan.
Q: Is this dish gluten-free or vegan?
A: Pesto sauce is naturally gluten-free, so simply pair with gluten-free pasta for a gluten-free meal. For a vegan version, omit cheese or use a vegan parmesan alternative and check your pasta is egg-free.
Q: Can I use other greens in place of basil?
A: While basil is classic, arugula, spinach, or kale can make wonderful alternative pestos with their own unique flavors.
Serving & Presentation Ideas
- Family Style: Pile pasta high on a large platter, top with scattered cheese shavings and fresh basil leaves.
- Summer Picnic: Prepare in advance and serve closer to room temperature alongside a spread of grilled vegetables, cold cuts, and crusty bread.
- Lunch Bowls: Layer white beans, cherry tomatoes, mozzarella, and grilled squash with dollops of pesto for a hearty salad alternative.
