Over the centuries, pesto has transformed from a humble regional Italian sauce into a globally loved culinary staple.
This fragrant, flavorful blend has adapted across continents, cuisines, and cultures, offering a remarkable example of food evolution through time.
Origins: From Liguria with Love
Pesto originated in Genoa, Liguria, in northwestern Italy. Its name comes from the Italian verb pestare, meaning to crush or pound, a nod to the traditional method of preparing it with a mortar and pestle.
🧑🍳 Tip: For a more traditional flavor, try making pesto with a mortar and pestle instead of a food processor—it releases oils more gently, enhancing aroma.
Interestingly, basil was not part of the original recipe. The earliest known reference to what resembles modern pesto appears in La Cuciniera Genovese (1863) by Giovanni Battista Ratto. He wrote:
“Take a clove of garlic, basil, grated Dutch and Parmigiano cheese, and mix them with pine nuts. Crush it all together in a mortar… then dissolve it with good and abundant oil.”
This historical recipe laid the groundwork for the classic pesto alla Genovese we know today.

Originally a simple Italian sauce, pesto has evolved into a versatile condiment used in a variety of dishes.
The traditional recipe has been adapted and modified resulting in a wide range of flavors and variations.
Expansion & Adaptation in America
As Italian immigrants settled in the United States, they brought with them a rich culinary heritage—including pesto. It began appearing in American publications as early as:
1928 – The Modesto Bee
1944 – The New York Times
1946 – Sunset Magazine
By the 1950s and 60s, Italian cuisine had become a beloved part of the American food scene. Pesto’s popularity surged in the 1980s and 90s, thanks to its versatility and fresh, bold flavor.
Reinvention: Variations and Global Influence
Though the classic pesto includes basil, garlic, Parmesan, pine nuts, and olive oil, modern versions have explored exciting new territory:
Herbs & Greens: Parsley, arugula, spinach, kale, and even cilantro have replaced basil in various recipes.
Nuts & Seeds: Pine nuts are often substituted with walnuts, pecans, hazelnuts, or cashews—such as in this Cashew Pesto Ravioli.
Cultural Fusions: Pesto has entered global fusion dishes, like a cilantro-walnut pesto featured in Latin-inspired recipes such as Green Bean Salad With Cilantro Sauce.
New Uses: Pesto isn’t just for pasta anymore! It’s become a favorite spread for sandwiches, grilled cheese, and even pizza.
One standout example is the Three Cheese Pesto Avocado Grilled Cheese which layers creamy avocado and a trio of cheeses with vibrant pesto for a melty, indulgent twist on a classic comfort food.
Pine nuts have been replace with hazelnuts as seen in this Sweet Tomato Gnocchi With Asparagus & Fresh Spinach Pesto.
Pesto in Pasta Traditions
In Liguria, pesto is traditionally served with Trofie pasta, a hand-rolled shape that clings perfectly to the sauce.
This can be seen in regional dishes like Trofie Al Pesto or its cousin, Rosso Pesto, made with sun-dried tomatoes, as in Trofie Al Rosso Pesto.
🧑🍳 Tip: Save a little pasta water when draining—it helps emulsify pesto into a silky, clingy sauce.
