The Ingredients for Pesto Sauce

With only 6 ingredients a great pesto sauce is super easy to make.

My HOT TIP is to use avocado oil. It tastes amazing and adds a gorgeous dark green hue to the basil pesto. I use Grove Avocado Oil which is very dark green and a personal favourite. (And yes, you can get it in the supermarket).

Pine nuts – while this recipe uses pine nuts you can honestly substitute any nuts you prefer.

How to Make It

Making basil pesto at home is very easy.

You will need a food processor or blender. I have included methods for both a food processor and basil pesto using a Thermomix. Both ways will make a perfect pesto.

Step 1. It really is as simple as toasting the pine nuts first. I do this in a pan over medium-high heat until they are lightly golden in colour. This step gives the pesto a nutty flavour from the toasting. Do this with any nuts you are using.

Step 2. Place all the ingredients into a food processor or Thermomix® and chop until smooth. If you need to scrape down the sides of the bowl and process again for a smoother consistency, then go for it. I prefer my pesto a little on the chunky side.

Quick Tips and FAQs

How to make a nut free pesto?

Oh, this one is easy. Seeds also work well in a pesto. I love toasted hemp seeds, pepitas or sunflower seeds as a nut free pesto alternative.

Can I freeze pesto?

You sure can. Personally, I prefer it fresh but if you would like to make it in a large batch then freeze it in an airtight bag.

How long does pesto last?

Any pesto sauce is best used within 2-3 days of making it. If it has been left in the fridge longer, I would use it in cooking rather than a fresh sprinkle over the top of a meal or dip.

What is the best way to serve pesto?

I love it sprinkled over a casserole, soup or baked breads and galettes. Basil pesto is also perfect for the lunch box or cheese platter. This pesto would be an awesome alternative to our red pesto in the Marry Me Chicken recipe too.
