Homemade vs Shop-Bought Pesto
One of the simplest and quickest meals we make is Pesto Pasta with lots of vegetables. The one thing that takes it to another level is homemade pesto. I’ll admit, I used to buy pesto for years. Until one day I had a pot of basil that was starting to look a bit sorry for itself on my window sill. I made my own Cheddar pesto and never looked back.
Since then, I’ve made numerous types of pesto, experimenting with different herbs, nuts, and cheese. Here, I present to you, my absolute favourite – Basil and Walnut Pesto with Cheddar! Quick and easy to make, it packs lots more flavour than a shop-bought pesto!

Ingredients
Have you ever asked yourself: ‘Can I use Cheddar instead of Parmesan in pesto?’. Well, we will tell you straight up: the answer is YES!
Simple delicious ingredients are what make this pesto: fragrant fresh basil, sharp mature cheddar, pungent garlic, walnuts, and zingy lemon, all finished with extra virgin olive oil.
This pesto has been tested with toasted and untoasted walnuts. I found that it’s slightly too bitter if I use toasted nuts. But the addition of lemon zest, alongside lemon juice, adds just the right amount of bitterness.

Method
To make this pesto you need either a food processor (or even a powerful smoothie maker/ blender) or a large pestle and mortar.
Using a Food Processor
If you’re using a food processor, all you need is to put all the ingredients, except for olive oil, into the processor and blitz until you reach a consistency that you like. Then mix in extra virgin olive oil at the end. Similarly, you can make pesto in a powerful blender/ smoothie maker. This method is great if you want a smooth pesto, without much texture.

Using a Pestle and Mortar
If you’re using a pestle and mortar, I recommend you chop your ingredients finely first to make your life easier. Put everything, but grated cheddar and olive oil in pestle and mortar, and crush until desired consistency is reached. Mix in cheese and olive oil at the end. Your pesto may have a more rustic look but will taste just as delicious. We actually prefer our pesto with a little bit of extra texture.

What To Use Walnut and Cheddar Pesto For?
The amounts in this recipe are for 3 portions of pasta. But I don’t want you to think that that’s all it can be used for. We love homemade pesto with cheddar used in a variety of different ways:
- Spread the pesto on the slices of bread, top with cheese and make delicious toasties.
- Mix your pesto with ground almonds, walnuts or breadcrumbs and spread on white fish before cooking in the oven.
- Pesto makes a delicious pizza topping too.

I love the idea of using walnuts and cheddar. Definitely more frugal ingredients than Parmesan and pine nuts.

I actually prefer pesto with walnuts to pine nuts and this version is so tasty with the cheddar too.

We prefer it too in many ways, lots of flavour and a lot less expensive too 🙂

Could you show how to incorporate crickets (or any kind of insect really) into this recipe, please.

Hi, Bill! Unfortunately, I am unfamiliar with cooking with insects.
