Sure, you can toss your pasta with basil pesto year-round, but doesn’t it feel better to stick to the seasons? Pasta tossed with tomatoes, basil pesto, and fresh mozzarella is perfect summer fare, but try tossing that same bright, fresh pesto with a Brussels sprouts and butternut squash pasta in November. It’s fine, you may say, but deep down you know there’s something not quite right. The bright herbaceous basil is an awkward match for those brooding winter vegetables. Enter Kale Pesto!
Substitute hearty winter kale for the delicate basil, and those winter squash and Brussels sprouts have finally met their match! Using more assertive toasted walnuts, thyme, fennel seeds for the milder almonds (or pine nuts) also takes this pesto a cool-weather direction.
How to make Kale-Walnut Pesto
Kale-Walnut Pesto is simple to make (and even simpler if you’ve got your bag of massaged kale in the fridge). Start by toasting the walnuts and garlic, which heightens the nuts’ flavor and tames the garlic’s assertive raw flavor. Add the fennel seeds and thyme to the walnuts and garlic a few minutes into the toasting process. This prevents them from burning. Once the skillet’s contents are fragrant, turn them into the food processor (no need to take time for them to cool), along with massaged kale and process. After you mince the kale, add the oil, and continue to process to a pesto-y paste consistency. Don’t forget the salt and pepper!
A dairy-free alternative to regular pesto
Kale-Walnut pesto is so flavorful you don’t need to add Parmesan cheese, but you may want to sprinkle your finished dish with a little Parmesan cheese before serving it.
What to serve kale pesto with?
The most obvious partner for kale-walnut pesto is pasta (don’t forget to save a little pasta cooking water for tossing), here’s our method for pasta pesto. But it’s also great drizzled over vegetables, beans, rice, and other cooked grains for an instant flavor boost.
The great thing about making large quantities of pesto in one kitchen session is that it freezes well. Simply jar up what you want for the fridge and freeze the remaining pesto in small freezer-safe covered containers—I like the little one-cup deli tubs. When you’re ready to thaw the pesto, simply pull it from the freezer and let come to room temperature. It won’t take long, but if you need it fast, microwave it on defrost, a minute at a time, until it’s thawed. And, if you’re tossing it in something hot— pasta, for example— you can add it partially frozen and let the hot dish finish the thawing.
