Pesto Genovese; one of Italy’s most successful exports. A perfect combination of floral, fragrant basil with nuts, cheese and garlic that creates a simple, no-fuss sauce for pasta. Homemade is best and this recipe shows you JUST how easy that is…

Pesto Genovese is one of Italy 's most iconic recipes. A delicious blend of flavour that is pretty much perfection. Created in the Ligurian city of Genoa, pesto is a dreamy combination of basil, cheese, olive oil, garlic and pine nuts (pignoli). The sauce can be crushed in a pestle & mortar or blended by machine, and each have the same, distinctive fragrance, texture and flavour.

It's an ancient dish, in that the Romans actually enjoyed a version using parsley. But when basil was introduced as the main ingredient some time in the mid 19th Century, Genovese pesto became the most popular version in Italy (and some parts of France too!)

Pesto is a versatile ingredient, being an excellent addition to sandwiches, for finishing soups and stews and most commonly, being tossed through cooked pasta for a quick and easy hit of flavour.

Pasta & Pesto - a happy marriage

Pasta and pesto work so perfectly together. It's a super quick way to inject flavour to pasta for a quick, healthy lunch - a couple of spoonfuls and a little pasta water and you're good to go. This pesto pasta recipe uses spaghetti, but pesto works with pretty much any pasta you like. Don't just stick with noodles, try hand shaped pasta like orecchiette or garganelli or fresh egg pasta fettuccini or pappardelle. You can even add spoonfuls between layers of lasagne sheets with ricotta cheese and tomato sauce. The combinations are endless.

Homemade pesto is so easy and successful, you'll be hard pushed to find a store-bought variety that beats it. You can make it in advance and store in the fridge for a week or freeze it for months and just defrost when you need it - how's that for convenience! You'll appreciate the effort and certainly the flavour.

As for cheese, the authentic pesto Genovese calls for a combination of Parmigiano Reggiano or Grana Padano cheese with Pecorino Sardo. Pecorino Sardo can be tricky to find outside of Italy, so I use Pecorino Romano, which is a close cousin and much easier to find.

Making your own pesto varieties

Even though the Pesto Genovese Recipe is the most popular and well known throughout the World, the word 'pesto' translates simply as 'pounded' - this generic term means that any ingredients pounded or pureed together can be called a pesto. I cook and create many types of pesto for pasta and the combinations are endless. Here are some suggestions that you might like to try at home...

Pesto varieties (all blended into a puree with salt & pepper)

  1. Cavolo nero cabbage (cooked), garlic, almonds, Parmigiano, extra virgin olive oil
  2. Spinach (cooked), pistachios, Parmigiano, extra virgin olive oil
  3. Anchovies, walnuts, garlic, Parmigiano, parsley, extra virgin olive oil (cooked for a while wth pasta water)
  4. English peas (cooked), oregano, mint, Parmigiano, melted butter, extra virgin olive oil
  5. Cherry tomatoes, blanched almonds, Parmigiano, extra virgin olive oil
