Basil Pesto: A Versatile Classic
Basil pesto, or Pesto alla Genovese, is a traditional Italian sauce originating in Genoa, Italy. Made with fresh basil, garlic, pine nuts, Parmesan cheese, and olive oil, it is a flavourful and aromatic sauce that has become a global favourite. Pesto's vibrant green colour and bold flavours make it a perfect addition to countless dishes.
History of Basil Pesto
The name “pesto” comes from the Italian word pestare, meaning “to pound” or “crush,” reflecting the traditional method of making pesto with a mortar and pestle. Its roots trace back to Liguria, where basil grows abundantly in the warm Mediterranean climate. The earliest recipes for pesto appeared in the 19th century, but its components—garlic, herbs, nuts, and cheese—date back to ancient Roman times.
Over the years, pesto has evolved to include variations with different nuts, herbs, and cheeses, but the classic Pesto alla Genovese remains the most iconic.
Ingrediants
- 2 cups fresh basil leaves (packed)
- 2–3 garlic cloves, peeled
- ¼ cup pine nuts (or walnuts as a substitute)
- ½ cup grated Parmesan cheese (or Pecorino Romano for a sharper flavour)
- ½ cup extra virgin olive oil
- ¼ teaspoon freshly ground black pepper
- ½ teaspoon salt (to taste)
Instructions:
- Prepare the Basil:
- Wash and pat dry the basil leaves thoroughly to prevent excess moisture.
- Toast the Pine Nuts (Optional):
- Toast the pine nuts in a dry skillet over medium heat for 2–3 minutes until golden and fragrant. Let them cool.
- Blend the Ingredients:
- In a food processor or blender, combine the basil, garlic, pine nuts, and cheese. Pulse until finely chopped.
- Add Olive Oil:
- With the processor running, slowly drizzle in the olive oil until the mixture forms a smooth paste.
- Season to Taste:
- Add salt and pepper, and pulse a few more times to combine.
- Adjust Consistency:
- For a thinner pesto, add more olive oil; for a thicker consistency, reduce the amount.

Tips for Making Perfect Basil Pesto
- Use Fresh Ingredients:
- Fresh basil, high-quality olive oil, and authentic Parmesan make a significant difference.
- Chill the Basil:
- For a brighter green pesto, keep basil leaves cool or briefly blanch them before blending.
- Adjust to Taste:
- Add more garlic, nuts, or cheese, depending on your preference.
- Avoid Over-Blending:
- Pulse the ingredients to maintain texture and prevent the basil from oxidising.
Storage and Shelf Life
Refrigeration
