Pesto sauce, a classic Italian condiment, has been a staple in many cuisines around the world. Its rich, herby flavor and vibrant green color have captured the hearts of many food enthusiasts. However, a common question often arises: is pesto sauce made of basil or parsley? In this article, we will delve into the world of pesto, exploring its origins, traditional ingredients, and the role of basil and parsley in its creation.
A Brief History of Pesto
Pesto sauce originated in the Liguria region of Italy, specifically in the city of Genoa. The name “pesto” is derived from the Italian word “pestare,” which means “to pound or crush.” This refers to the traditional method of making pesto, where ingredients are pounded together using a mortar and pestle.
The earliest recorded recipe for pesto dates back to the 16th century, and it was originally made with garlic, pine nuts, Parmesan cheese, and basil. The sauce was traditionally served with trofie, a type of twisted pasta, and was a staple in Genovese cuisine.
Traditional Ingredients of Pesto
So, what are the traditional ingredients of pesto sauce? The classic recipe consists of:
- Fresh basil leaves
- Garlic
- Pine nuts (or walnuts)
- Parmesan cheese
- Extra virgin olive oil
- Salt
These ingredients are combined in a specific ratio to create the perfect balance of flavors. The basil provides a bright, herby flavor, while the garlic adds a pungent kick. The pine nuts add a rich, nutty flavor, and the Parmesan cheese provides a salty, umami taste. The olive oil brings everything together, creating a smooth and creamy sauce.
The Role of Basil in Pesto
Basil is the star of the show when it comes to pesto sauce. The sweet, aromatic flavor of fresh basil leaves is what gives pesto its distinctive taste. In fact, the original recipe for pesto calls for a specific type of basil known as “basilico genovese,” which is a protected designation of origin in the European Union.
Basil is not only essential for the flavor of pesto, but it also plays a crucial role in the sauce’s texture. The leaves are pounded together with the other ingredients to create a smooth, creamy paste. The basil also helps to thicken the sauce, making it perfect for coating pasta.
The Role of Parsley in Pesto
So, where does parsley come into play? While parsley is not a traditional ingredient in pesto sauce, it is sometimes used as a substitute for basil. Parsley has a milder flavor than basil, with a slightly bitter taste. Some people prefer the taste of parsley in their pesto, while others find it too bland.
In some parts of the world, parsley is used in combination with basil to create a unique flavor profile. This is particularly common in Middle Eastern cuisine, where parsley is a staple herb. However, in traditional Genovese pesto, parsley is not used.
Why Some Pesto Sauces May Contain Parsley
So, why do some pesto sauces contain parsley? There are a few reasons for this:
- Availability: Basil can be difficult to find in some parts of the world, particularly during the off-season. Parsley, on the other hand, is widely available and can be used as a substitute.
- Cost: Basil can be expensive, particularly if you’re using high-quality, fresh leaves. Parsley is generally cheaper and can be used to reduce the cost of pesto production.
- Flavor preference: Some people simply prefer the taste of parsley in their pesto. This is particularly true in regions where parsley is a staple herb.

If you’re looking to make traditional pesto sauce, be sure to use high-quality, fresh basil leaves. Avoid using parsley as a substitute, as it can alter the flavor and texture of the sauce.

What is the traditional herb used in making pesto sauce?
The traditional herb used in making pesto sauce is basil. In fact, the name “pesto” is derived from the Italian word “pestare,” which means “to pound or crush,” referring to the process of pounding basil leaves with garlic, pine nuts, Parmesan cheese, and olive oil to create the sauce. Basil is the primary ingredient in classic Genovese pesto, and its sweet, slightly spicy flavor is what gives pesto its distinctive taste.
While some recipes may call for other herbs like parsley, spinach, or kale, basil is the traditional and preferred choice for making authentic pesto sauce. The quality and flavor of the basil leaves can greatly impact the overall taste of the pesto, so it’s essential to use fresh, high-quality basil for the best results.
Can parsley be used as a substitute for basil in pesto sauce?
While parsley can be used as a substitute for basil in pesto sauce, it will change the flavor and character of the sauce. Parsley has a milder, more bitter flavor than basil, which can result in a slightly different taste profile. If you don’t have basil or prefer the taste of parsley, you can use it as a substitute, but keep in mind that it won’t be traditional pesto.
That being said, parsley pesto can be a delicious and refreshing alternative to traditional basil pesto. Some people even prefer the taste of parsley pesto, so it ultimately comes down to personal preference. If you do decide to use parsley, use the curly-leaf variety, as it has a milder flavor than the flat-leaf variety.
What are the key differences between basil and parsley pesto?
The key differences between basil and parsley pesto lie in their flavor profiles and aromas. Basil pesto has a sweet, slightly spicy flavor and a bright, herbaceous aroma, while parsley pesto has a milder, more bitter flavor and a fresher, greener aroma. The color of the two pestos also differs, with basil pesto having a deeper green color and parsley pesto having a lighter, more yellowish-green color.
In terms of usage, basil pesto is often paired with richer, more robust ingredients like pasta, pizza, and meat, while parsley pesto is often used as a sauce for lighter dishes like fish, vegetables, and salads. Ultimately, the choice between basil and parsley pesto comes down to personal preference and the type of dish you’re making.
Can other herbs be used to make pesto sauce?
Yes, other herbs can be used to make pesto sauce. While basil and parsley are the most traditional and commonly used herbs, other herbs like spinach, kale, cilantro, and dill can be used to make delicious and unique pesto sauces. Each herb will impart its own flavor and aroma to the pesto, so feel free to experiment and find the combination that you enjoy the most.
Some popular herb combinations for pesto include spinach and garlic, kale and lemon, and cilantro and chili peppers. You can also add other ingredients like sun-dried tomatoes, roasted garlic, or grated carrot to create a more complex and interesting flavor profile.
How do I choose the best basil for making pesto sauce?
When choosing basil for making pesto sauce, look for fresh, high-quality leaves with no signs of wilting or discoloration. The best basil for pesto is sweet basil, also known as Genovese basil, which has large, tender leaves with a sweet, slightly spicy flavor. Avoid using Thai basil or lemon basil, as they have a stronger, more pungent flavor that may overpower the other ingredients in the pesto.
It’s also essential to use fresh basil, as dried or frozen basil can lose its flavor and aroma. If you’re growing your own basil, harvest the leaves in the morning, after the dew has dried but before the heat of the day. This will help preserve the delicate flavor and aroma of the basil.
Can I make pesto sauce without garlic?
Yes, you can make pesto sauce without garlic. While garlic is a traditional ingredient in pesto, it’s not essential, and you can omit it or substitute it with another ingredient if you prefer. Some people may not like the flavor of garlic or may be allergic to it, so it’s perfectly fine to make garlic-free pesto.
If you do choose to omit the garlic, you can add other ingredients like lemon juice, zest, or grated ginger to add depth and brightness to the pesto. Keep in mind that the flavor of the pesto will be slightly different without garlic, so you may need to adjust the amount of salt, cheese, or other ingredients to taste.
How do I store pesto sauce to preserve its flavor and aroma?
To store pesto sauce and preserve its flavor and aroma, transfer it to an airtight container and cover it with a thin layer of olive oil. This will help prevent the pesto from oxidizing and losing its flavor. You can store the pesto in the refrigerator for up to one week or freeze it for up to six months.
When freezing pesto, it’s essential to use airtight containers or ice cube trays to prevent the formation of ice crystals, which can damage the texture and flavor of the pesto. Frozen pesto is perfect for using in soups, stews, and sauces, while refrigerated pesto is best used as a sauce for pasta, pizza, and other dishes.
