Step‑by‑Step Instructions for Grilled Chicken Sandwich with Pesto
Step 1: Prepare the Pesto
In a food processor, add fresh basil leaves, arugula, pine nuts, garlic, and Parmesan cheese. Blend the mixture while gradually drizzling in high-quality olive oil until you achieve a smooth, vibrant pesto consistency. This homemade pesto will be the flavorful foundation of your Grilled Chicken Sandwich with Pesto, so be sure to scrape down the sides as needed to ensure everything is well combined.
Step 2: Marinate the Chicken
Take your chicken breasts and coat them generously with olive oil, minced garlic, and your choice of herbs, such as oregano or thyme. Allow the chicken to marinate for at least 15 minutes at room temperature to absorb the flavors. This step enhances the juiciness of the chicken, making your grilled chicken sandwich even more delicious when cooked.
Step 3: Grill the Chicken
Preheat your grill or grill pan to medium-high heat, about 375°F (190°C). Once hot, place the marinated chicken on the grill and cook for approximately 6-7 minutes per side, or until the internal temperature reaches 165°F (75°C). Look for a nice char and juices running clear, which indicates that your chicken is perfectly grilled and ready for your sandwich.
Step 4: Assemble the Sandwich
On slices of rustic bread, evenly spread the homemade pesto on both sides. Place the grilled chicken breast on the bottom slice, followed by slices of smoked mozzarella cheese. Add sun-dried tomatoes and a handful of fresh arugula for a peppery crunch, then top it with the second slice of bread. The combination of these ingredients creates the ultimate Grilled Chicken Sandwich with Pesto.
Step 5: Serve with a Warm Touch
For an extra delicious finish, consider grilling the assembled sandwich in a panini press or on a heated skillet for 2-3 minutes, pressing down gently until the cheese melts and the bread is golden brown. Slice the sandwich in half to reveal the tasty layers, and serve it warm for a gourmet experience that will impress your family and friends.

Make Ahead Options
These Gourmet Grilled Chicken Sandwiches with Pesto are perfect for busy weeknights! You can prepare the homemade pesto and refrigerate it for up to 3 days, ensuring vibrant flavors are maintained.

Additionally, you can pre-slice your rustic bread and sun-dried tomatoes for quick assembly when hunger strikes. When you’re ready to serve, simply spread the pesto on the bread, layer in the grilled chicken and cheese, then grill the sandwich for a delightful finish that’s just as delicious as if it were made fresh!
Expert Tips for Grilled Chicken Sandwich with Pesto
- Marinate Well: Ensure chicken is marinated for at least 15 minutes. This infuses flavor and keeps the grilled chicken moist and delicious in your sandwich.
- Check Temperature: Always cook chicken to an internal temperature of 165°F. This guarantees it’s fully cooked while maintaining juiciness—a key factor for a perfect grilled chicken sandwich with pesto.
- Grill to Perfection: Make sure the grill is preheated before adding the chicken. A hot surface prevents sticking and ensures nice grill marks, enhancing the visual appeal and flavor.
- Pesto Power: For a vibrant green pesto, blanch the basil quickly in boiling water before blending. This step enhances the color and fresh taste of your grilled chicken sandwich.
- Cheese Melting Tip: If you love gooey cheese, consider covering your sandwich briefly with a lid while it cooks. This traps heat and steam, melting the smoked mozzarella perfectly without burning the bread.

Grilled Chicken Sandwich with Pesto Recipe FAQs
How do I select ripe ingredients for my sandwich?
Absolutely! When choosing your ingredients, look for rustic bread with a good crust that feels firm and has no dark spots. For chicken, fresh breasts should be plump and pink with no signs of discoloration. Opt for smoked mozzarella that’s creamy and slightly springy and select sun-dried tomatoes that are supple, not hard or shriveled.
What’s the best way to store leftovers?
Store any leftover assembled Grilled Chicken Sandwiches in an airtight container for up to 2 days. To maintain the freshness of the ingredients, I recommend keeping the pesto separate until you’re ready to enjoy, ensuring that the bread doesn’t become soggy.
Can I freeze the grilled chicken?
Yes! For longer storage, wrap individual grilled chicken breasts tightly in plastic wrap, then place them in a freezer-safe bag. They can be stored for up to 3 months. When ready to use, thaw the chicken in the fridge overnight. For a quick meal, warm it in the oven or skillet before assembling your delicious sandwich.
What should I do if my pesto turns brown?
Pesto can turn brown if exposed to air for too long. To prevent this, store it in an airtight container and press plastic wrap directly onto the surface of the pesto before sealing. Additionally, blanching the basil before blending can enhance its vibrant color. If your pesto has already turned, a quick stir can help mix in any green oil that may have risen to the top.
Are there any dietary considerations for my sandwich?
Absolutely! If you’re catering to dietary restrictions, consider using gluten-free bread options. For a dairy-free version, substitute smoked mozzarella with vegan cheese or leave it out altogether. Additionally, nuts can be an allergen; you may choose sunflower seeds as a nut-free alternative in the pesto.
How do I ensure my grilled chicken is juicy?
It’s simple! Marinate the chicken for at least 15 minutes to infuse flavor and moisture. Grill on a preheated grill to seal in juices and cook until the internal temperature reaches 165°F (75°C). A digital meat thermometer is a great tool to ensure perfect doneness every time, keeping your chicken succulent for that perfect Grilled Chicken Sandwich with Pesto!
