Pesto Genovese | Authentic Italian Basil Pesto

pesto genovese Pesto Genovese is an uncooked cold sauce made only with 7 ingredients: Genovese basil DOP, extra virgin olive oil (Possibly of the Ligurian Riviera), Parmigiano Reggiano (or Grana Padano), Pecorino cheese (Fiore Sardo), pine nuts, garlic and salt. It was born in Liguria, a beautiful region situated in northern Italy. It’s one of the sauces most used in our country and nowadays it’s famous all over the world.

This is the official recipe of the Consorzio Pesto Genovese that is very specific about exactly where the ingredients should come from. We know that it’s difficult to find all the ingredients of the Italian tradition in foreign countries, but if you want to make the recipe for Genovese pesto that you would eat in Italy, stick to these ingredients as much as possible. So do what you can, but don’t add ingredients that have nothing to do with the authentic recipe (we’ve noticed this in many recipes) such as ricotta cheese, cashew nuts, seeds oil, green beans or lemon juice.

So for example do with the basil that you find in your country. Or grow it! It’s really easy to grow basil: just get some basil seeds (possibly Genovese basil variety) and a small guide of how to grow basil.

Pesto Recipe: Marble Mortar or Food Processor?

Traditionally authentic Pesto Genovese recipe is made with a marble mortar and pestle. It’s a long and tiring work, therefore in this recipe we will use a food processor with some tricks. In 15 minutes you will have a very delicious pesto sauce, green and tasty!

Marble mortar and pestle make sure that basil leaves do not darken. The steel blades of the food processor tend to oxidize basil. This way you’ll have a very dark green and slightly bitter pesto. But with our help you will have a very green pesto even with a food processor.
If you do not take some care and follow some tips, the result will not be excellent using a food processor. That’s why you have to carefully follow the instructions below.

An Electric Food Processor is a kitchen tool you may need for this recipe. The food processor is used for chop, slice, whisk, knead and has variable speeds you can set on your own speed as well as a pulse mode. Look here to check some options.

Blend all the ingredients for about 1 minute.

Step 4) – Before seasoning, if the pesto is very thick, add 1/2 tablespoons of the cooking water; this way you’ll have a warm homogeneous soft pesto sauce ready for your pasta dish. You can even taste Genovese pesto spread on toasted bread, as an appetizer. Delicious!

How to Store Pesto

How to make Pesto Genovese with Mortar and Pestle

If instead you want to try making pesto with mortar and pestle, here are the steps to follow:

  1. After washing the basil leaves, dry them thoroughly on a kitchen towel.
  2. Place the garlic in a large marble mortar with a few grains of salt and start pounding with the pestle.
  3. Add the pine nuts and crush them, obtaining a rather coarse mush.
  4. Add the basil leaves while continuing to gently crush, then add the two grated cheeses and mix everything together.
  5. Soften the mixture by slowly pouring the oil until you have a homogeneous, creamy consistency, then transfer it to a bowl and finish mixing it with the remaining oil.

Some precautions:

  1. You must never step on the leaves with force, but gently rotate the pestle along the walls of the mortar, so as to tear them up without cutting them.
  2. The processing must take place at room temperature and not take too long, to avoid oxidation which alters the flavor and color of the basil.
  3. The quantity of garlic can be reduced or increased according to personal taste, but the total lack alters the original taste.
  4. Some make an addition of walnuts, tolerable variant, but cashews, parsley and lemon must be avoided.

    Thank you for the guidance and recipe for Pesto. I have been making Pesto for a long time. A few days ago I got about 5 pounds of beautiful basil! So I thought I would make lots and give to my friends. Did everything right – everything is clean and all of that. Put them in 500ml jars – and left them out for the time being because my kitchen is quite cold. They were fine yesterday. This morning I noticed some oil a the bottome of the jars! Opened one and it exploded!!! Pesto oil went everywhere!! The jars did not break. I have no idea what went wrong. Not enough ‘head space’? — was my jar too big thus building up too much gas? — kitchen not warm enough and they should be in the fridge?
