Basil pesto, a classic Italian sauce, has been a staple in Mediterranean cuisine for centuries. Its vibrant green color and rich, herby flavor have captivated the hearts of foodies and home cooks alike. But have you ever wondered what makes this sauce so special? What is in basil pesto, and how do its ingredients come together to create such a delicious and iconic condiment? In this article, we’ll delve into the world of basil pesto, exploring its history, ingredients, and secrets.
A Brief History of Basil Pesto
Basil pesto originated in the Liguria region of Italy, specifically in the city of Genoa. The name “pesto” comes from the Italian word “pestare,” which means “to pound or crush.” This refers to the traditional method of making pesto, which involves pounding the ingredients together using a mortar and pestle. The sauce has been a staple in Ligurian cuisine since the 16th century, when it was served with trofie, a type of twisted pasta.
The Classic Ingredients of Basil Pesto
So, what is in basil pesto? The classic recipe consists of just a few simple ingredients:
- Fresh basil leaves
- Garlic
- Pine nuts (or walnuts)
- Parmesan cheese
- Salt
- Extra virgin olive oil
These ingredients may seem straightforward, but the quality and proportion of each component can greatly impact the final flavor and texture of the pesto.
The Star of the Show: Fresh Basil
Fresh basil is the foundation of basil pesto. The leaves should be bright green, fragrant, and free of bitterness. There are several varieties of basil, but the most commonly used is sweet basil (Ocimum basilicum). This variety has a sweet, slightly spicy flavor and a delicate aroma.
When selecting fresh basil, look for leaves with no signs of wilting or yellowing. The leaves should be firm and fragrant, with a slightly sweet aroma. Fresh basil is a delicate herb, and its flavor and aroma can quickly deteriorate if not stored properly. To keep basil fresh, store it in a cool, dry place, away from direct sunlight.
The Flavor Enhancer: Garlic
Garlic is a fundamental component of basil pesto, adding a pungent flavor and aroma to the sauce. The amount of garlic used can vary depending on personal taste, but traditionally, three to four cloves are used per recipe.
When using garlic in pesto, it’s essential to mince it finely to release its natural oils and flavor compounds. This can be done using a garlic press or a microplane grater.
The Crunchy Element: Pine Nuts
Pine nuts, also known as pignoli, are the edible seeds of the pine tree. They have a rich, nutty flavor and a crunchy texture, which adds depth and complexity to the pesto.
Pine nuts can be expensive, so some recipes may substitute them with walnuts or almonds. However, pine nuts are the traditional choice, and their unique flavor and texture are essential to the classic pesto recipe.
The Cheesy Element: Parmesan
Parmesan cheese, also known as Parmigiano-Reggiano, is a hard, aged cheese with a nutty, salty flavor. It’s a staple in Italian cuisine and adds a rich, savory flavor to the pesto.
When using Parmesan in pesto, it’s essential to grate it finely to release its natural oils and flavor compounds. This can be done using a microplane grater or a food processor.
The Binding Agent: Extra Virgin Olive Oil
Extra virgin olive oil is the binding agent that holds the pesto together. It adds a rich, fruity flavor and a smooth, creamy texture to the sauce.
When selecting olive oil for pesto, choose a high-quality extra virgin oil with a low acidity level. This will ensure that the oil doesn’t overpower the other flavors in the pesto.
The Art of Making Basil Pesto
Making basil pesto is an art that requires patience, skill, and practice. The traditional method involves pounding the ingredients together using a mortar and pestle, but modern recipes often use a food processor or blender.
Here’s a simple recipe to get you started:
Ingredients:
- 2 cups fresh basil leaves
- 3 cloves garlic, minced
- 1/2 cup pine nuts
- 1/2 cup grated Parmesan cheese
- Salt, to taste
- 1/4 cup extra virgin olive oil
Instructions:
- Rinse the basil leaves and pat them dry with a paper towel.
- In a food processor or blender, combine the basil leaves, garlic, and pine nuts. Process until the mixture is well combined and the basil is finely chopped.
- Add the Parmesan cheese and process until the cheese is well combined with the basil mixture.
- Season the pesto with salt to taste.
- With the processor running, slowly pour in the olive oil through the top. Process until the pesto reaches the desired consistency.
- Taste and adjust the seasoning as needed.
Tips and Variations
Here are some tips and variations to help you take your basil pesto to the next level:
- Use high-quality ingredients: The quality of your ingredients will directly impact the flavor and texture of your pesto. Choose fresh, fragrant basil, and high-quality olive oil and Parmesan cheese.
- Don’t overprocess: Pesto should have a slightly coarse texture. Overprocessing can result in a smooth, paste-like consistency that’s unappealing.
- Add a squeeze of lemon: A squeeze of fresh lemon juice can add brightness and balance out the flavors in the pesto.
- Experiment with different herbs: While basil is the traditional choice, you can experiment with other herbs like parsley, cilantro, or dill to create unique flavor profiles.
- Add some heat: If you like a little heat in your pesto, you can add some red pepper flakes or sliced jalapeños to the mixture.

How do I choose the best basil for making pesto?
When choosing basil for making pesto, it’s essential to select fresh and high-quality leaves. Look for basil leaves that are bright green in color, have no signs of wilting, and have a sweet and aromatic fragrance. The most commonly used variety of basil for making pesto is Genovese basil, also known as sweet basil. This variety has large, flat leaves with a sweet and slightly spicy flavor.
Avoid using basil leaves that are wilted, brown, or have a bitter taste. These leaves can give the pesto a bitter flavor and an unpleasant texture.

Be sure to stop the processor frequently to scrape down the sides and ensure that all the ingredients are well mixed.

How do I store basil pesto to keep it fresh?
Basil pesto can be stored in the refrigerator or freezer to keep it fresh. To store basil pesto in the refrigerator, transfer it to an airtight container and cover it with a layer of olive oil.
