Fennel Frond Pesto

Fennel Pasta from ScratchI might have planted a TON of fennel this year.  And by a ton, I mean about 12 plants.  I love fennel.  However, it also means that my garden beds are exploding with not just the little growing fennel bulbs, but also their huge fronds (greens).  It’s a little out of control.  My husband says our garden beds look like they have afros.  “Delicious sweet anise afros!”  Was my response.  So since I’d never grown fennel before, I wasn’t 100% sure when to harvest them.  I totally thought they were a root veggie and that most of the bulb was actually underground, but in harvesting these guys, I quickly realized that my little fennel bulbs were definitely not ready.  But I still had the beautiful fronds that had that wonderful fennel anise aroma.  Fennel PestoThe best part of pesto?   You can pretty much make it out of any greens!  Basil, of course, but also parsley, and in my case, the gazillion fennel fronds I have in my garden!Fennel Pesto from ScratchThe second best thing about pesto?  It’s so easy.  Just toss your greens, a toasted nut (pine nuts is a standard, but I’ve used almonds, hazelnuts, and in this case, walnuts because it’s all we had on hand), fresh lemon juice, salt, and olive oil.Fennel pesto from scratchBlended up until it’s the consistency you want.  Want an oily-er, loose pesto? Add more oil!  Want a more concentrated pesto?  Less oil.  Totally customize-able.Fennel Pesto from scratch! I just love this pesto.  It has a wonderful sweet anise flavor to it!  Mix it with some simple pasta, as a condiment on a sandwich, or use it on some green beans and poached egg.  Hooray for not letting these big gorgeous fronds go to waste!  

Pesto also freezes beautifully!  When I make a lot, I use an Ice Tray and fill each tray with some pesto, top it with a touch more olive oil, cover with plastic wrap and then freeze.  When they’re set, pop the little cubes out, store them in little baggies, and you can have fresh From Scratch Pesto on hand anytime you want!

  • How wonderful, our fennel is just abut getting to the stage where we could have away some of the fronds… I usually use them as a flavouring in soup but this sounds wonderful!

    We must have around 80-100 fennel plants 😀

    • 80-100!! Amazing!!! And yes- I can’t wait to use the fronds for soups and stocks, too! It’s been waayyy too hot here to think about soup yet, but when it is, I can’t wait to use them 🙂

      • I hear you on the heat thing, we are struggling here in Central Europe too! We have loads of food in the garden but usually struggle to grow fennel so always plant way too many but this year they all worked… Nice problem to have 😉

        I love to braise them in butter with a little pastis and then serve them in a homemade vegetable broth and a poached egg garnished with the fronds, a really lovely and refreshing summer soup, in fact I do that with loads of summer vegetables, anything that is good at the time and a simple tasty fresh dinner.
