Ingredients

  • Fresh Basil Leaves – Do not substitute fresh basil for dried leaves.
  • Toasted Pine Nuts – If you cannot get a hold of toasted pine nuts, buy regular pine nuts and toast them for a few minutes in a dry frying pan. Adding untoasted pine nuts can be the cause of a condition called pine mouth, so I wouldn’t recommend the risk.
  • Garlic – This gives our Pesto a little added depth of flavour.
  • Parmigiano Reggiano – An authentic Italian parmesan. You can substitute it for regular parmesan if you wish.
  • Pecorino Romano – This is a hard cheese with a strong flavour made from sheep milk. It is produced in the Lazio region of Italy. If you find the taste too strong you can substitute it for Grana Padano or more Parmesan cheese.
  • Salt – We use salt for seasoning. There is salt present in the hard cheese so you can omit this added extra if you prefer a lower sodium option.
  • Extra Virgin Olive Oil – I recommend a good quality extra virgin olive oil for authenticity. However, be aware that it does not blend well and can produce a bitter taste. It is best to stir it in after the ingredients have been blended or use a regular olive oil as a substitute.
  • Lemon Juice – This helps to prevent the pesto from turning brown. It is an optional ingredient however, so you don’t have to add it.

Where does Pesto come from?

Pesto originated in Liguria in Italy, you will often see the commercial types called Pesto alla Genovese, which is pesto that comes from Genoa, the capital of Liguria. This is the most popular type seen throughout the world.

Although the main ingredients in traditional pesto usually consist of the same things; Basil leaves, pine nuts, hard cheese, garlic and olive oil. There can be regional differences and basil pesto recipes can differ slightly from each other.

The name Pesto comes from the Italian word “pestare” which means “to pound” or to grind. Since, pesto was originally made using a pestle and mortar. You can also find other recipe variations without basil using the name pesto. In Sicily, for example, you often find Pesto al Pistachio which uses fewer basil leaves and pistacchio verde di Bronte (green pistachio from Bronte) in place of the pine nuts. Pesto Rosso is another example that is based on the use of sun dried tomatoes, making the sauce red and giving it it’s name. Around the world, there are many deviations from the traditional recipe, using a variety of greens and various different nuts to create the pounded sauce.


Step-By-Step How To Make Authentic Pesto Genovese

Step 1: Prepare Basil

  • Thoroughly wash and dry the basil leaves, ensuring to remove most of the water.

Step 2: Chop Basil and Toast Pine Nuts

  • Roughly chop the basil leaves.
  • If needed, toast the pine nuts in a dry frying pan for a few minutes.

Step 3: Crush Pine Nuts and Garlic

  • Using a pestle and mortar, pound the pine nuts until crushed.
  • Crush the garlic using a pestle and mortar.

How to Prevent Fresh Pesto Turning Brown

Unfortunately, due to the fresh ingredients, pesto can quickly oxidise and turn brown when exposed to the air.

You can use a little lemon juice like we have in this recipe to help keep the bright green colour in your pesto looking vibrant.

An alternative way to prevent pesto turning brown is to blanche the leaves before adding to the recipe.

To blanche the basil leaves; simply place the leaves in boiling water for no more than 10 seconds and immediately transfer them to an ice bath. Drain and dry the leaves well, before adding into your recipe.

Always store the pesto in an airtight container and place it in the fridge or freezer until you’re ready to use it.

You may also notice that Fresh Pesto has a slightly different smell to Shop Bought Pesto. That’s because everything is fresh and the basil is yet to be cooked. It has not been through any processing to make it last. However, be aware that it does have a limited shelf life and since it is so quick to make, I would always recommend using it when you make it.

FAQ

How long does fresh pesto last?

Fresh pesto will store for up to 3 days in an airtight sterilised jar in the fridge. You can also freeze it for up to 6 months, but, be sure to freeze immediately upon making it. I recommend using an ice cube tray and freezing your pesto in portions.

Why does my homemade Pesto taste bitter?

This can be caused by using olive oil that is past its best. However, the most common reason is because you added the extra virgin olive oil to the blender. Blending the oil can produce a bitter taste, so we recommend stirring it in afterwards.

Why does fresh pesto turn brown?

The brown colour is caused by oxidisation, you can counter it by adding lemon juice to the pesto or blanching the basil leaves before adding them to the recipe.


How to Use Authentic Pesto Genovese

Italian Pesto is extremely versatile and can be used in so many different ways.

You can use green basil pesto as an alternative to tomato sauce on a pizza. It goes well with a topping of roasted cherry tomatoes, mozzarella and parmesan. Add some fresh rocket leaves on top when your pizza leaves the oven.

A very simple recipe for Pesto is to stir it into warm cooked pasta and top with Parmesan. The flavours are amazing and it’s a very quick meal that’s ready in under 15 minutes. It goes down really well with kids too. You can also add green beans and peas to make it extra healthy too.

To make a super quick creamy pesto sauce for pasta. Simply add cream cheese and stir it in to warm, freshly cooked pasta.

You can try these roasted pesto vegetables, for an alternative to simple roast potatoes. Or try this easy meal with Pesto Pasta and Roasted Tomatoes. For something really special, make these Bruschetta Burrata.

Mixing in a teaspoon of pesto to mayonnaise, gives you a great dip that goes well in a burger, or as a sauce for potato wedges.

Pro Tips and Guidance

  • Wash the fresh basil leaves and dry the leaves thoroughly – before adding to the blender. Extra surface water on the leaves can affect the texture of the finished Pesto.
  • If you cannot find Pecorino Romano or Parmigiano Reggiano cheese, using Grana Padano is fine. You can also use a basic parmesan cheese but the flavours of the cheese will not be as matured as an authentic Italian cheese.
  • Enhance the Pesto – By using roasted garlic.
  • Avoid Pine Mouth –Traditionally, untoasted pine nuts were used. I recommend toasting your nuts first, before adding, due to a condition called Pine Mouth. Pine mouth is a condition that affects your sense of taste. Eating raw pine nuts, for some people, can create a strange metallic taste which can last up to 2 weeks.

  • Freeze – You can also freeze it in an airtight container in the freezer for up to 6 months. It is best to freeze it in the portion sizes you may want to use in the future.
