Ingredients You’ll Need
You’ll be amazed by how a handful of humble ingredients come together to make something so extraordinary. Every element in this recipe shines, bringing its distinct touch to the taste, texture, and even the vibrant green color that pops off the plate.
- Pasta (12 ounces, your choice): Use spaghetti, linguine, or any favorite shape; the noodles soak up the pesto beautifully.
- Walnuts (1 cup): They provide a creamy, earthy richness and give the pesto its signature depth.
- Fresh basil leaves (2 cups, packed): Packed with aromatic flavor and that gorgeous green hue.
- Grated Parmesan cheese (1/2 cup): For salty, umami goodness and a luscious creaminess in the sauce.
- Garlic (2 cloves, minced): Adds that irresistible pungent kick to wake up all the flavors.
- Olive oil (1/2 cup): The backbone of any good pesto, making the sauce silky and rich.
- Lemon juice (from 1/2 lemon): A splash of citrus brightens everything up.
- Salt (1/2 teaspoon): Seasoning is essential—this brings all the flavors together.
- Black pepper (1/4 teaspoon): A touch of heat to balance those creamy and tangy notes.
- Extra grated Parmesan and chopped walnuts (optional, for garnish): Sprinkling on top gives you both crunch and extra cheesy magic.
How to Make Pasta with Walnut Pesto
Step 1: Cook the Pasta
Begin by bringing a large pot of salted water to a boil. Drop in your pasta of choice and cook it until it’s perfectly al dente, following the timing on the package for best results. Don’t forget to reserve half a cup of pasta water before draining – this is your secret weapon for a silky pesto sauce! Once drained, set the pasta aside while you make that irresistible walnut pesto.
Step 2: Prep the Walnut Pesto
In the bowl of a food processor, combine the walnuts, fresh basil leaves, grated Parmesan, and minced garlic. Pulse several times until everything is finely chopped. You want a consistency that’s even but still has a little texture—it shouldn’t be a total paste just yet!
Step 3: Make the Creamy Sauce
With the processor running, slowly drizzle in the olive oil and squeeze in the juice of half a lemon. Keep blending until the pesto becomes smooth and creamy. At this point, season generously with salt and black pepper, and give it one last taste to make sure it’s just right.
Step 4: Toss Pasta with Walnut Pesto
Transfer the cooked pasta to a large bowl, then add the walnut pesto. Use tongs to gently toss everything together, adding a bit of reserved pasta water as needed to help the sauce cling beautifully to each noodle. Aim for a glossy, well-coated finish that makes every forkful irresistible.
Step 5: Serve and Savor
Divide your pasta into bowls and finish each serving with an extra sprinkle of grated Parmesan and a handful of chopped walnuts if you like a little crunch. Serve immediately while everything is warm and fragrant.
How to Serve Pasta with Walnut Pesto

Garnishes
A dish as striking as Pasta with Walnut Pesto deserves a finishing touch! Go for a snowy blanket of extra Parmesan, a scattering of toasted chopped walnuts, and perhaps a few torn basil leaves to really show off its green color. A drizzle of your best olive oil heightens the flavor and adds shine.
Side Dishes
Pair your Pasta with Walnut Pesto with a lively arugula salad tossed in lemon vinaigrette, or some garlicky roasted vegetables for a satisfying, complete meal. A crusty loaf of Italian bread is never out of place—perfect for mopping up every last drop of leftover sauce.
Creative Ways to Present
Go beyond the bowl! Serve the pasta in a big platter for family-style sharing, or twirl neat nests onto individual plates for an elegant dinner. Leftover walnut pesto makes a fabulous spread for crostini or a vibrant drizzle over grilled chicken or roasted veggies, making this recipe a versatile star in your kitchen.
Make Ahead and Storage
Storing Leftovers
Leftovers of Pasta with Walnut Pesto keep well in an airtight container in the fridge for up to three days. If you know you’ll have extras, store some of the pesto separately to stir into the noodles just before reheating for the freshest taste.
Freezing
You can absolutely freeze walnut pesto! Simply transfer it to a freezer-safe container (skip the cheese if you want the smoothest texture), press some plastic wrap against the surface, and seal. Thaw overnight in the fridge, stir in the cheese, and toss with freshly cooked pasta whenever you crave a taste of summer.
Reheating
To bring leftover Pasta with Walnut Pesto back to life, add a splash of water or olive oil before reheating gently on the stove or in the microwave. This helps loosen up the sauce so it’s just as creamy as when first served.
FAQs
Can I use a different nut instead of walnuts?
Yes! While walnuts deliver a rich, earthy flavor, you can substitute with pecans, almonds, or even cashews for a slightly different twist—just know the flavor will change a bit, but the results will still be delicious.
Is this recipe gluten-free?
If you swap in your favorite gluten-free pasta, Pasta with Walnut Pesto becomes instantly gluten-free. The pesto itself contains no gluten, making it a versatile and inclusive dish.
Do I really need a food processor?
While a food processor makes quick work of the pesto, you can absolutely use a high-powered blender or even a mortar and pestle for a more rustic, hands-on version. The texture may be chunkier, but the taste will still shine.
Can I make Pasta with Walnut Pesto ahead of time?
You can prepare the walnut pesto up to three days ahead and refrigerate it in an airtight container. For the best flavor, toss it with hot pasta just before serving so the sauce is fresh and aromatic.
What pasta shape works best?
Spaghetti and linguine are classic picks, but don’t be afraid to experiment! Short shapes like fusilli or rigatoni catch pockets of pesto beautifully, making every bite a treat.
Final Thoughts
If you’re looking for a dish that’s elegant enough for guests and easy enough for Wednesday night dinner, Pasta with Walnut Pesto is your answer. This recipe proves that a few good ingredients and a little creativity can make weeknight magic—so grab some basil and walnuts, and let dinner become your new favorite ritual!
