Let’s dive into the history, ingredients, and step-by-step instructions to make this culinary masterpiece at home.

The History

The roots of this modern dish trace back to two distinct culinary traditions: Italian pesto and American grilling culture. Pesto, originating from Genoa in the Liguria region of Italy, has been a staple sauce since the 19th century. Traditionally made with fresh basil, pine nuts, garlic, Parmesan cheese, and olive oil, pesto was originally crushed using a mortar and pestle—a practice still revered by purists today. The name “pesto” comes from the Italian word pistare, meaning “to pound” or “to crush,” reflecting its labor-intensive beginnings.

Grilled chicken, on the other hand, became popular in American cuisine during the mid-20th century as outdoor grilling gained popularity. With its smoky flavor and lean protein profile, grilled chicken emerged as a go-to choice for health-conscious eaters and food enthusiasts alike. The fusion of Italian herbaceousness with American grilling techniques gave rise to countless recipes, including pesto-marinated grilled chicken.

Zucchini noodles, meanwhile, are a relatively recent innovation, gaining widespread attention in the 2010s as part of the low-carb and paleo diet movements. Spiralizing vegetables like zucchini into noodle shapes offered a creative alternative to traditional wheat-based pasta. When combined with pesto and grilled chicken, zoodles not only reduce calorie intake but also enhance the freshness and texture of the meal. Today, Pesto Grilled Chicken with Zucchini Noodles stands as a symbol of modern fusion cooking—honoring tradition while embracing innovation and wellness.

Ingredients Breakdown

To create a flavorful and balanced Pesto Grilled Chicken with Zucchini Noodles, selecting high-quality ingredients is key. Below is a detailed breakdown of each component:

Pesto Sauce (Homemade):

Fresh Basil Leaves: The star of any authentic pesto, basil provides a sweet, slightly peppery aroma that defines the sauce. Use about 2 cups packed fresh leaves for maximum flavor.
Pine Nuts: These add a buttery richness and creamy texture. Lightly toast them before blending to enhance their nutty depth.
Garlic: One to two cloves lend a sharp, pungent kick that balances the sweetness of the basil.
Extra Virgin Olive Oil: High-quality EVOO acts as the base, carrying the flavors smoothly and adding heart-healthy monounsaturated fats.
Parmesan Cheese: Freshly grated Parmigiano-Reggiano adds umami and saltiness. Avoid pre-grated versions, which may contain anti-caking agents.
Salt and Black Pepper: Essential seasonings to round out the taste.

Grilled Chicken:

Chicken Breasts: Boneless, skinless chicken breasts are ideal for even cooking and absorbing marinade well. Aim for uniform thickness to prevent overcooking.
Olive Oil: Helps the spices adhere and prevents sticking on the grill.
Lemon Juice: Adds brightness and helps tenderize the meat.
Minced Garlic: Infuses the chicken with aromatic depth.
Dried Oregano and Thyme: Earthy herbs that complement the pesto.
Salt and Pepper: For seasoning the chicken inside and out.

Zucchini Noodles:

Zucchinis: Choose firm, medium-sized zucchinis with smooth skin. Two medium ones typically yield enough noodles for two servings.
Kosher Salt: Used to draw out excess moisture from the zoodles after spiralizing, preventing a soggy dish.
Olive Oil (optional): A light drizzle can prevent sticking when sautéing.

Garnishes and Optional Additions:

Cherry Tomatoes: Halved for bursts of sweetness and color.
Red Onion Slices: Thinly sliced for a tangy crunch.
Pine Nuts or Walnuts: Toasted and sprinkled on top for extra texture.
Fresh Basil Leaves: For garnish and enhanced herbal aroma.
Lemon Zest: Brightens up the entire dish.
Additional Parmesan: Shaved or grated over the final plate.

Step-by-Step Recipe

Step 1: Make the Homemade Pesto

In a dry skillet over medium heat, toast the pine nuts for 3–5 minutes until golden and fragrant. Stir frequently to avoid burning.
In a food processor or blender, combine the toasted pine nuts, 2 cups fresh basil leaves, 1–2 garlic cloves, and ½ cup freshly grated Parmesan cheese.
Pulse several times until coarsely chopped.
With the machine running, slowly drizzle in ⅓ to ½ cup of extra virgin olive oil until the mixture forms a smooth paste.
Season with salt and freshly ground black pepper to taste. Set aside. (You can store extra pesto in an airtight container with a thin layer of oil on top for up to one week in the fridge or freeze for longer storage.)

Step 2: Marinate the Chicken

Place 2 boneless, skinless chicken breasts between sheets of plastic wrap and gently pound them to an even ¾-inch thickness for consistent grilling.
In a bowl, whisk together 3 tablespoons olive oil, juice of half a lemon, 1 minced garlic clove, ½ teaspoon dried oregano, ½ teaspoon dried thyme, ½ teaspoon salt, and ¼ teaspoon black pepper.
Add 2 tablespoons of the prepared pesto to the marinade and mix well.
Place chicken in a resealable bag or shallow dish, pour marinade over it, and coat evenly. Refrigerate for at least 30 minutes, or ideally 2–4 hours for deeper flavor.

Step 3: Prepare the Zucchini Noodles

Wash and trim the ends off 2 medium zucchinis.
Using a spiralizer, cut them into spaghetti-like noodles. If you don’t have a spiralizer, use a julienne peeler or a box grater with large holes.
Place the zoodles in a colander, sprinkle with ½ teaspoon kosher salt, and toss gently. Let sit for 10–15 minutes to release excess water.
Rinse briefly under cold water to remove salt, then pat dry thoroughly with paper towels or a clean kitchen towel.

Step 4: Grill the Chicken

Preheat your grill or grill pan over medium-high heat (about 375°F–400°F).
Remove chicken from the marinade and let excess drip off. Discard used marinade.
Lightly oil the grates to prevent sticking.
Grill chicken for 5–6 minutes per side, depending on thickness, until internal temperature reaches 165°F and juices run clear.
During the last minute of cooking, brush the top of the chicken with additional pesto for a glossy, flavorful finish.
Transfer to a plate, cover loosely with foil, and let rest for 5 minutes before slicing.

Step 5: Cook the Zucchini Noodles

Heat 1 tablespoon olive oil in a large skillet over medium heat.
Add the drained zucchini noodles and sauté for 2–3 minutes, stirring gently, just until tender but still crisp (avoid overcooking, which makes them mushy).
Alternatively, serve the zoodles raw for a completely raw, crunchy texture.
Stir in 1–2 tablespoons of pesto to coat the noodles evenly and add flavor.

Step 6: Assemble the Dish

Divide the pesto-coated zucchini noodles among serving plates.
Slice the rested grilled chicken diagonally into strips and arrange on top of the noodles.
Drizzle with additional pesto, sprinkle with cherry tomatoes, red onion, toasted pine nuts, and Parmesan.
Garnish with fresh basil leaves and a twist of lemon zest for a bright finish.

Tips

Prevent Soggy Zoodles: Salting and draining zucchini noodles is crucial. Skipping this step can result in a watery dish.
Don’t Overcook Zoodles: They cook quickly! Just 2–3 minutes in the pan is enough. Think al dente.
Use Fresh Basil: Dried basil won’t give the same vibrant flavor. If absolutely necessary, triple the amount, but fresh is best.
Marinate Longer for More Flavor: Overnight marination yields juicier, more flavorful chicken.
Rest the Chicken: Allowing the chicken to rest ensures juicy slices instead of dry meat.
Grill Marks Matter: Don’t move the chicken too soon. Wait until it releases easily from the grates for those perfect sear lines.
Customize Your Pesto: Swap pine nuts for walnuts or almonds, or add spinach for a milder taste and added nutrients.
Make Ahead: Pesto can be made days in advance and stored. Zoodles should be prepared close to serving time to maintain texture.
Low-FODMAP Option: Replace garlic with garlic-infused oil and omit onions for a digestive-friendly version.
Vegan Adaptation: Skip the chicken, use tofu or chickpeas, and replace Parmesan with nutritional yeast in the pesto.

Variations and Customizations

This recipe is incredibly adaptable. Here are some creative twists to keep your meals exciting:

Protein Variations:

Shrimp: Marinate peeled shrimp in pesto and grill quickly (2–3 minutes per side).
Salmon: Brush salmon fillets with pesto and grill skin-side down for crispy skin and moist flesh.
Tofu or Tempeh: Press, marinate, and grill for a plant-based powerhouse option.
Chicken Thighs: Juicier and more flavorful than breasts, though higher in fat.

Noodle Alternatives:

Yellow Squash: Mix with zucchini for color and mild flavor.
Carrot Ribbons: Use a peeler for sweet, colorful strands.
Spiralized Sweet Potato: Roast first for a heartier bite.
Spaghetti Squash: Bake and shred for a natural noodle substitute.

FAQ

Can I make this recipe ahead of time?

Yes, but with caveats. The pesto can be made 3–5 days in advance and stored in the fridge with a layer of oil on top. Chicken can be marinated overnight. However, zucchini noodles are best prepared fresh to avoid sogginess. Cook them just before serving.

Can I bake the chicken instead of grilling?

Absolutely. Preheat oven to 375°F. Place marinated chicken on a lined baking sheet and bake for 20–25 minutes, basting with pesto halfway through, until cooked through.

Is this recipe freezer-friendly?

The pesto freezes beautifully for up to 3 months (in ice cube trays for portioning). Cooked chicken can be frozen for up to 3 months. Zucchini noodles do not freeze well due to high water content.

How do I prevent my zoodles from getting watery?

Salt them after spiralizing and let them drain in a colander. Rinsing and drying thoroughly removes excess moisture. Also, avoid overcooking—sauté only briefly.

Can I use store-bought pesto?

Yes, for convenience. Look for brands with simple ingredients: basil, olive oil, nuts, cheese, garlic. Avoid artificial preservatives or added sugars.

What can I substitute for pine nuts?

Walnuts, almonds, cashews, or sunflower seeds work well. Each imparts a slightly different flavor but maintains creaminess.

Is this dish suitable for kids?

Yes! Many children enjoy the mild flavor of zucchini and the savory pesto. You can blend spinach into the pesto for added nutrients without changing the taste much.

Can I eat this cold?

Definitely! This dish makes an excellent cold salad for meal prep. Chill components separately and assemble just before eating to maintain texture.
