Pasta Al Pesto is one of the iconic Italian pasta dishes made with two traditional Ligurian ingredients: word famous basil Pesto Genovese and short, twisted shape pasta with thinner ends known by the name trofie or trofiette. Trenette, linguine and even spaghetti is another very popular choice for pasta al pesto.
Its vibrant colors, unforgettable herby, slightly spicy taste paired with slightly firm ‘al dente’ pasta and creamy sauce make it an art and an experience in and of itself.
Pasta al pesto, together with Pasta Caprese should be on the summer food bucket-list of any Italian food lover!
As obvious as it might sound, in Trofie Al Pesto or in any pasta al pesto for that matter pasta and pesto are not the only ingredients. In its best Italian tradition it is always made with two very modest additional ingredients: potatoes and green beans.
Creaminess of the potatoes mellows the vibrant taste of basil pesto. Slightly crunchy green beans are refreshing to the palette. Everything is topped with optional but much appreciated earthy pine nuts as a nod to the nuts in the pesto sauce.

How To Make - Step By Step
If you’re using store-bought pesto skip directly to making pasta al pesto. If you’re planning to use your own frozen pesto, make sure to thaw it before use, preferably in the fridge.
Step 1: Prepare Basil Pesto.
- In a food processor add cheese, garlic, pine nuts and salt. Blitz until crumbly.
- Start adding basil leaves alternating with extra virgin olive oil. Blitz until smooth. Make sure to stop frequently and scrape the sides of the bowl.

Step 2: Cook pasta, potatoes and beans.
- Peel, wash and cut potatoes into ½ inch (1 cm) thick cubes.
- Wash and trim green beans cutting each into 1.5 inch (4 cm) long pieces.
- In a pot filled with cold water add potato cubes. Bring water and potatoes to a boil, add salt and pasta.
- Cook for 2 minutes then add green beans. Continue cooking for another 6-8 minutes (depending on the pasta type you've chosen) until pasta is cooked ‘al dente’ - has a slight bite to it.
- Reserve 1-2 cups of cooking liquid then drain.
Step 3: Put everything together.
- Transfer pasta with potatoes and green beans to a large bowl.
- Add pesto and pine nuts.
- Mix gently adding some pasta cooking liquid to help pasta get perfectly coated with pesto. If desired you can finish it with a generous drizzle of extra virgin olive oil.
- Serve with freshly grated Parmesan cheese.
Top Tips For Success
- Reserve some pasta cooking liquid. You’ll need it to help pesto sauce perfectly coat the pasta and give it its signature extra creaminess.
- Use leftover potatoes and green beans. If you have any leftover cooked potatoes and green beans from making Potato & Green Beans salad feel free to use them in this recipe. In this case you’ll need to dice potatoes and cut green beans and add them to the bowl with pasta and pesto.
- Make bright green pesto that never turns brown. Even when mixed with hot pasta. Use the trick I shared in the dedicated to Pesto Genovese. This way you’ll easily impress your guests with bright green pasta al pesto that never turns brown (which, by the way, is an absolutely natural process of oxidation that happens to basil and does not much effect the taste).
- Pay attention to pasta cooking time. Depending on the pasta you’ve chosen for your pasta al pesto you might add green beans at the same time with pasta. Check instructions for pasta cooking time on the package (it’s different for all types of pasta!). Now consider that green beans cook in about 8-10 minutes.
So if pasta cooks for the same time add them to the pot together. If pasta requires more than 10 minutes of cooking time it’s best to add pasta first and after a couple of minutes add green beans. This way green beans will still be slightly crunchy while pasta will be perfectly 'al dente' as it should be.
FAQs
The most traditional pasta for pesto is without a doubt - trofie or trofiette pasta. After all, it comes from the same region as authentic Pesto Genovese!
While most types of pasta it’s produced on industrial basis these days, it’s a type of hand–made pasta with history.
Some say their origin dates back the times of the Crusades. They were produced by rubbing - with a quick and expert movement of the hand - thin, short cylinders of dough on the pastry board.
Despite apparent simplicity of the process this pasta shape is quite difficult to make by novice.
Besides trofie, pasta al pesto can be made with long pasta shape like trenette (typical to Liguria) and more common linguine and spaghetti. Make sure they’re bronze cut and made of durum wheat flour.
While technically you can use any kind of pasta shape, it’s best to trust Italian on their pasta choice mentioned above.
As a rule of thumb, use 2 tablespoons on pesto per pasta serving. The exact amount of course depends on personal taste.
Keep in mind that pesto always need to be slightly diluted with pasta cooking water to have perfect creamy consistency that will coat pasta without letting it drown in the sauce.
It’s best to start with a heaping tablespoon per person, mix, taste and add more if needed.
