Spinach pesto in a jar with olive oil on top

We’ve all got back pocket recipes that we can throw together with what we have on hand, and mine is pesto sauce. Once you learn how to make pesto sauce, you’ll realize very quickly that it can be made with a wide variety of greens, herbs, nuts and cheese.

There’s so much more than classic basil pesto sauce. I prepare carrot top pesto and this Spinach Pesto recipe much more often because I have the ingredients on hand often and basil isn’t always in season.

This recipe is special to me because I created it during one of my practical exams in cooking school.   We were allowed to choose two types of produce and create a composed dish with them.  I chose butternut squash and spinach, and made this beautiful butternut squash galette topped with pesto.  

My instructor loved it, and I’ve been making it ever since. 🙂
