This Parsley Pesto Pasta with Cashews is an easy, gluten-free and healthy dinner, ready in just 15 minutes.
- Traditional pesto sauce recipes use fresh basil and pine nuts.
- Basil can often be hard to find and pine nuts are expensive.
- Swapping basil for parsley and pine nuts for creamy cashew nuts is a great alternative.
You don’t need a food processor to make it. All you need is a simple hand blender.
Is pesto healthy
Pesto can certainly be part of a healthy diet. This pesto recipe is made with fresh parsley, cashew nuts, garlic, extra virgin olive oil and Parmesan cheese. Fresh herbs like parsley, nuts, garlic and extra virgin olive oil are widely considered to come with a bunch of health benefits. Plus, a good quality Parmesan is one of the highest protein cheeses. Parmesan has approximately 38 grams of protein per 100 grams, compared to 25 grams per 100 grams for cheeses like cheddar.
Homemade pesto is also usually healthier than store-bought brands. Jars of pesto at the supermarket are usually made with refined vegetable oils because they are cheaper. They sometimes have added sugar and preservatives as well. Making your own pesto at home allows you to use good quality extra virgin olive oil and skip the unnecessary sugar and preservatives.
Can I use parsley instead of basil in pesto
Parsley works well as a substitute for basil in pesto recipes. The great thing about parsley is that it’s usually easier to find and can be less expensive than basil.
I choose flat-leaf parsley, which is also sometimes called continental parsley or Italian parsley. The leaves are delicate and fragrant. However, curly parsley should also work. If you try the recipe with curly parsley I’d love to hear how it goes.
What cheese is best for pesto
Pesto is usually made with Parmesan cheese. Parmigiano Reggiano is the authentic Parmesan cheese made in Italy. For a cheese to be labelled as Parmigiano Reggiano, it has to be made in certain parts of Italy. You will see the name stencilled on the rind of the cheese.
If you’re outside of the European Union, Parmesan is simply the generic term for cheeses inspired by Parmigiano Reggiano. Generic Parmesan cheeses are usually a pretty good alternative. They can sometimes taste saltier than Parmigiano Reggiano, so that’s why I suggest starting with a smaller amount of salt in this pesto recipe and then adding more to taste if needed.
If you can’t find a block of Parmigiano Reggiano or Parmesan, sharp or aged cheddar cheese also works quite well. It’s easy to find at any supermarket. I would just avoid pre-grated cheese because anti-caking agents are usually added to stop the cheese from clumping together. Pre-grated Parmesan cheese can also smell terrible.
How to add pesto to pasta
It’s always a good idea to save some of your pasta cooking water to add to the pesto as you stir it through the pasta. The starch that is released from the pasta into the water while it’s cooking helps the sauce to become extra creamy and stick to the pasta. This applies whether you have made your own pesto or are using a store-bought jar.
The amount of cooking water needed will depend on the thickness of your pesto sauce and how thoroughly you drained the pasta. Once your pasta is cooked, use a mug to extract a cup of the cooking water before draining. You can watch the recipe video below to see how I do this.
Then, after you have drained your pasta, dollop the sauce onto the pasta and start stirring it through. If the sauce is clumping and not coating the pasta well, start adding small splashes of the cooking water as you stir. This will loosen the sauce and help you get that delicious creamy texture.
Ingredients for parsley pesto with cashew nuts
- Parsley – I use flat-leaf parsley in this recipe, also known as continental or Italian parsley.
- Cashew nuts – Unsalted cashew nuts work best. You can also use pine nuts, which are more traditional for pesto, or another creamy nut like Brazil nuts or macadamia nuts.
- Freshly-grated Parmesan – Use a block of Parmesan cheese, or Parmigiano Reggiano if possible, and grate it yourself. If you can’t find Parmesan, a block of sharp or aged cheddar also works.
- Extra virgin olive oil – I love to use a really peppery extra virgin olive oil. But any olive oil will work. You could also use avocado oil.
- Garlic – Freshly minced garlic gives the sauce a kick. You can add more or less garlic to suit your taste.
- Salt – Essential to liven up the sauce. I start with a small amount, then add more to taste depending on the saltiness of the cheese.
- Gluten-free pasta – I use a gluten-free penne pasta made from quinoa and rice flours. But any pasta will work.
How long does parsley pesto last in the fridge
Pesto sauce should last for up to three days in the fridge in an airtight container. You can also freeze pesto sauce in ice cube trays. This allows you to defrost the sauce in smaller portions in the fridge as needed.
If you have added freshly-made pesto to cooked pasta, any leftovers can also be stored in the fridge in an airtight container for up to three days. Leftover cooked pasta generally needs to be eaten within three days to be safe.

Notes
- Pasta – I use a gluten-free pasta made from quinoa and rice flours. But any pasta will work. Just follow the instructions on the packet to cook it, and remember to save some of the starchy cooking water before draining to loosen the sauce.
- Parsley – Wash the parsley by submerging the bunch in a bowl or sink of cold water and swishing it around. Rinse under cold running water, then shake off the excess water. Pick the leaves from the stems and measure the amount needed for the recipe.
- Parmesan – A generic Parmesan, or authentic Parmigiano Reggiano, is best when you buy it in a block and grate it yourself. You could also use sharp or aged cheddar cheese, which is easy to find at the supermarket.
- Storage – The pesto sauce should last for 3 days in the fridge in an airtight container. You can also freeze it in ice cube trays and defrost in the fridge in portions as needed. If you have added the freshly-made pesto to cooked pasta, any leftovers can also be stored in the fridge in an airtight container for up to 3 days.
