How to Make Chicken & Vegetable Penne with Parsley-Walnut Pesto Recipe
Step 1: Prepare the Vegetables
Start by preheating your oven to 375°F (190°C) and lining a baking sheet with parchment paper. This simple step ensures your veggies roast evenly. Arrange the sliced zucchini and diced bell pepper on the sheet, drizzle them generously with olive oil, and season with salt and pepper. Roasting these vegetables for about 15 to 20 minutes will bring out their natural sweetness and give them a tender, caramelized edge, which adds a lovely depth to the final dish.
Step 2: Cook the Penne Pasta
While your vegetables are roasting, it’s time to cook the penne pasta. Follow the package instructions carefully to achieve that perfect al dente texture—firm but not tough. Once cooked, drain the pasta well and set it aside. This step is crucial because perfectly cooked pasta is the backbone of your meal.
Step 3: Whip Up the Parsley-Walnut Pesto
Next, let’s create the star component: the parsley-walnut pesto. In a food processor, combine fresh parsley leaves, toasted walnuts, minced garlic, olive oil, lemon juice, salt, and black pepper. Pulse the mixture until it reaches a smooth consistency that’s still a bit textured for that fresh, homemade vibe. If you want, add Parmesan cheese and pulse just enough to blend it in. This pesto is zesty, nutty, and herbaceous, perfectly complementing the rest of your ingredients.
Step 4: Combine Pasta, Chicken, and Roasted Vegetables
In a large mixing bowl, toss together the cooked penne, shredded or diced chicken, roasted zucchini and bell pepper, and halved cherry tomatoes. The tomatoes add juiciness and freshness that contrast beautifully with the warm roasted veggies and protein-packed chicken. Then, spoon in your vibrant parsley-walnut pesto and toss gently until everything is evenly coated in that irresistible, green-hued sauce.
Step 5: Serve and Enjoy
Your Chicken & Vegetable Penne with Parsley-Walnut Pesto Recipe is now ready to be served warm. Garnish with additional Parmesan cheese if you like to add a savory touch that melts beautifully over the warm pasta. The combination of textures—from tender pasta to crunchy walnuts and juicy vegetables—makes every bite a joy.
How to Serve Chicken & Vegetable Penne with Parsley-Walnut Pesto Recipe

Garnishes
A sprinkle of extra Parmesan cheese adds a rich, savory layer that balances the bright pesto. Fresh parsley leaves on top also add a pop of green and hint at the herbal flavor inside. If you want just a touch of heat, a pinch of red pepper flakes can add a delightful zing.
Side Dishes
This dish pairs beautifully with a simple green salad, perhaps with a lemon vinaigrette to echo the citrus in the pesto. Garlic bread or crusty bread on the side helps mop up any leftover sauce, adding another delicious texture. A light, chilled glass of white wine can also complement the herbaceous and nutty flavors of the meal.
Creative Ways to Present
Try serving this penne recipe in individual shallow bowls, allowing the vibrant colors of the veggies and pesto to shine through. For a more casual presentation, a big, rustic serving bowl with plenty of freshly grated Parmesan invites everyone to dig in family-style. Adding a few lemon wedges on the side offers a lovely burst of freshness just before eating.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store them in an airtight container in the refrigerator. The pasta will keep well for up to three days. Because the pesto is fresh, flavors might deepen overnight, giving you a delicious cold or reheated meal the next day.
Freezing
This Chicken & Vegetable Penne with Parsley-Walnut Pesto Recipe can be frozen, but keep in mind that fresh pesto can lose some brightness after freezing. For best results, store pasta and vegetables separately from the pesto. Freeze them in airtight containers for up to two months, then combine and freshen with a little extra lemon juice or olive oil when reheating.
Reheating
When reheating, warm the pasta and veggies gently on the stovetop or microwave. Add a little drizzle of olive oil or splash of water to keep the dish moist. To revive the pesto’s fresh flavor, stir in an extra spoonful of fresh pesto or a squeeze of lemon right before serving.
FAQs
Can I use other nuts instead of walnuts in the pesto?
Absolutely! While walnuts give a lovely mild crunch and flavor, you can substitute with pine nuts, almonds, or even pecans depending on what you have. Each nut brings its own character to the pesto.
Is this dish good served cold or only warm?
This dish is versatile and delicious both warm and cold. Served cold, it makes an excellent pasta salad that’s perfect for lunches or picnics.
Can I make the pesto without garlic?
Yes, if you prefer a milder taste or have garlic sensitivities, simply omit the garlic. The parsley and walnuts still create a flavorful base.
What can I substitute for Parmesan if I’m vegan or dairy-free?
Try using nutritional yeast, which offers a cheesy, nutty flavor without dairy. It works wonderfully in the pesto and keeps it creamy and tasty.
How long does the pesto last in the fridge?
Fresh pesto typically stays fresh for about 3 to 5 days when stored in an airtight container in the refrigerator. To help prevent browning, drizzle a thin layer of olive oil over the surface before sealing.
