Simple Basil and Walnut Pesto

It's that time of year when summer is starting to fade, and the garden is bursting with basil ready for picking! The best way I've found to preserve all that basil for the winter months is to make pesto and store it in the freezer. This way, you will have pesto whenever you crave it during the winter months!

I feel like I've consumed so much pesto this year compared to any other year! The basil was definitely thriving! This year I planted my basil from seed, and from 5 plants I got a lot of basil!

Just look how beautiful these leaves are! I'm really going to miss the basil in the colder months, BUT we will still have pesto!

Making the Pesto

Traditionally, pesto is made with pine nuts, but pine nuts are expensive, and walnuts make such a great substitute! I love the flavour they bring to the pesto. The warm and nutty flavour really livens up the dish you put it in.

First, we are going to start with the walnuts in the food processor. I found this the best way to start of with the pesto, especially in an older food processor - the one I'm using is properly from the late '80s!

After the addition of the garlic, we added the basil. You may have to stop and scrape down the sides. Add in the rest of the ingredients and blend until well combined. Taste the pesto and adjust where needed.

I don't like to add too much oil initially. I will add some extra oil on top of the pesto in the container before storing it in the freezer. This is just a preference; you can add more oil while making the pesto if you would like it to be more liquid.

How to store

Anytime I make fresh pesto, I always portion it off and store it in the freezer. I found this the best way for longevity: place them in a ½ cup Rubbermaid freezer-safe container, top them with olive oil and freeze! Anytime I want to use pesto for the week, I will pull it out of the freezer on Monday morning to defrost, and it will be ready to use in a couple of hours for the rest of the week.

How to use

You can use this in so many ways! I usually make pasta with it, BUT you can do so much.

  • Pasta
  • Pizza base
  • Pizza topping
  • In a sandwich
  • In a salad

In everything pretty much!
