Trenette al pesto, potatoes and green beans is a traditional Ligurian dish.
Tradition calls for the use of potatoes and green beans, and the result is a very simple but great-tasting dish.
For me it is a childhood memory, I remember when I was a child and they would put in front of me a nice plate of trenette al pesto with potatoes and green beans, and I would devour it in no time.
The recipe is really simple to prepare and anyone can make it.
It will certainly take much longer to prepare than to enjoy.
If you then have leftover, it is even better the next day repassed in the pan so that it makes a crust.
If you can’t find trenette from the pasta factory, you can make it directly or substitute it with linguine.

Steps for pesto
▪ Rinse the basil leaves under cold running water, then dry them on a tea towel by gently patting and rubbing.
▪ Peel the garlic clove and remove the core, then place it in a marble mortar and process it with a wooden pestle until it becomes a cream.
▪ Add pine nuts and reduce them too to a cream.
▪ At this point add the basil leaves and coarse salt and begin to pound, alternating strokes with rotary motions.
▪ When the mixture has a creamy and smooth consistency, add the grated Pecorino cheese.
▪ Also add the Parmesan cheese, incorporating it well with the wooden pestle.
▪ As a final step, pour the extra virgin olive oil in a drizzle, continuing to swirl the wooden pestle until it is incorporated.
▪ Pesto is ready!
