About This Recipe
There's something deeply satisfying about a pesto that doesn't rely solely on tender basil — the kale and walnuts in this version give the sauce a hearty, earthy backbone that stands up beautifully against pasta. The toasted walnuts add a pleasant crunch and richness, while the kale softens into the sauce without losing its character, creating something far more substantial than the typical springtime pesto.
Canadian home cooks gravitate toward this recipe because it feels like autumn on a plate. With just twenty minutes from pot to table, it's the kind of weeknight dinner that satisfies without demanding much effort — especially welcome when the days are short and the fridge is stocked with whatever greens survived the garden season.
Tips for the Best Kale Walnut Pesto Pasta
Toast the walnuts in a dry skillet over medium heat for two to three minutes before blending — this unlocks their nutty depth and prevents the pesto from tasting flat. When you toss the cooked pasta with the sauce, add the reserved pasta water a splash at a time; you want the sauce clinging to every strand, pooling slightly at the bottom of the bowl.
What to Serve With It
This pesto pairs wonderfully with a crisp white wine like a BC Riesling or a light Pinot Noir, and a simple arugula salad dressed with lemon and shaved Parmigiano keeps things bright alongside the rich pasta. A loaf of warm crusty bread is essential for soaking up every last bit of sauce, and if you're feeding a hungry crowd, tuck in a side of roasted root vegetables or seared chicken thighs.
Storage & Reheating
Transfer leftovers to an airtight container and refrigerate for up to three days — the pesto will darken slightly as the kale oxidizes, but the flavour holds up well. Reheat gently in a skillet with a splash of water or broth to loosen the sauce before tossing with fresh pasta, or stir cold pesto directly into hot noodles off the heat. Freeze in ice cube trays for future meals.
