How to Make Chicken & Vegetable Penne with Parsley-Walnut Pesto Recipe
Step 1: Roast the Vegetables
Start by heating your oven to 375°F (190°C) and lining a baking sheet with parchment paper. Spread the sliced zucchini and diced bell pepper on the sheet, then drizzle with olive oil and sprinkle with salt and pepper. Roasting the vegetables brings out their natural sweetness and gives them a tender, lightly browned texture that is simply irresistible.
Step 2: Cook the Penne Pasta
While the veggies roast, cook the penne according to the package directions until al dente. Drain the pasta and set it aside to keep warm. The al dente texture ensures the pasta will stay firm and hold up well when mixed with the sauce and ingredients.
Step 3: Prepare the Parsley-Walnut Pesto
In a food processor, add fresh parsley leaves, toasted walnuts, minced garlic, olive oil, lemon juice, salt, and pepper. Pulse everything until the mixture is smooth and luscious. If you love that little boost of savory richness, toss in the grated Parmesan cheese and pulse again until fully combined. This pesto is the soul of the dish — fresh, nutty, and bright all at once.
Step 4: Combine All Ingredients
In a large mixing bowl, toss together the cooked pasta, shredded chicken, roasted vegetables, and halved cherry tomatoes. Then, pour in the parsley-walnut pesto and toss gently but thoroughly until every piece of pasta and veggie is coated with that vibrant green sauce. This step lets all the flavors mingle beautifully for an unforgettable taste experience.
Step 5: Serve Warm
Dish out the penne while it’s still warm, and if you want, sprinkle on a little extra Parmesan cheese for that final touch. Every bite is a celebration of freshness, texture, and comforting all in one bowl.

Garnishes
Finishing touches can make a simple dish shine. Try garnishing your plate with some extra chopped parsley, a few whole toasted walnuts for crunch, or a light sprinkle of grated Parmesan to add even more depth. These garnishes not only enhance the flavor but add attractive pops of green and texture to your presentation.
Side Dishes
A fresh green salad with a lemon vinaigrette or a crusty piece of warm bread works beautifully alongside this pasta dish. These sides keep everything light and fresh while complementing the rich flavors of the pesto and roasted vegetables.
Creative Ways to Present
Serve this dish in deep pasta bowls to hold all the saucy goodness. For a casual gathering, consider layering the pasta in individual mason jars or colorful bowls so guests can see the vibrant colors and enticing textures. You can also drizzle extra pesto on top at the table, giving everyone the chance to customize their flavor intensity.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Because this dish combines cooked pasta and pesto, it keeps well without losing flavor or texture, making for a delicious next-day meal.
Freezing
While fresh is best, you can freeze the Chicken & Vegetable Penne with Parsley-Walnut Pesto Recipe if needed. Place it in a freezer-safe container and freeze for up to 2 months. Keep in mind that the pesto might change texture slightly upon thawing, but the flavors will still shine through beautifully.
Reheating
When ready to enjoy leftovers, gently reheat in a skillet over medium heat. Add a splash of water or olive oil to keep the pasta moist and prevent sticking. Heating slowly preserves the texture of the pasta and keeps the pesto fresh and vibrant.
FAQs
Can I use other types of nuts instead of walnuts in the pesto?
Absolutely! Pine nuts, almonds, or even pecans work wonderfully as alternatives. They will each bring a slightly different flavor and texture, but the pesto will remain delicious and nutty.
Is it possible to make this recipe vegetarian?
Yes, simply omit the chicken and increase the vegetables or add a plant-based protein like chickpeas or tofu. The pesto is already vegetarian, so the dish remains full of flavor and satisfying.
Can I prepare the pesto ahead of time?
You sure can! Make the parsley-walnut pesto up to two days in advance and store it in an airtight container in the fridge. Just give it a quick stir before using, and if it thickens, whisk in a little olive oil to loosen it up.
What type of pasta works best for this recipe?
Penne is perfect because its tube shape holds onto the pesto and chunks of veggies well, but rigatoni, fusilli, or farfalle would also be great choices for texture and presentation.
How can I make this dish gluten-free?
Simply swap regular penne for a gluten-free penne pasta that cooks similarly. Many gluten-free pastas are made from rice, corn, or chickpeas and will work great in this recipe without compromising taste.
Final Thoughts
I can’t recommend the Chicken & Vegetable Penne with Parsley-Walnut Pesto Recipe highly enough.
