Step‑by‑Step Instructions for Italian Chicken Pesto Sandwich
Step 1: Prep Chicken
Begin by placing halved boneless skinless chicken breasts in a mixing bowl. Season them generously with garlic powder, dried basil, dried oregano, salt, and coarse black pepper. Let the chicken absorb these flavors for about 10 minutes while you prepare your grill pan or stovetop grill, ensuring it’s ready to create that perfect char.
Step 2: Grill Chicken
Heat your grill pan over medium-high heat until it’s sizzling hot, about 5 minutes. Add the seasoned chicken breasts, cooking them for approximately 3 minutes on each side. Look for the chicken to turn golden brown, and use a meat thermometer to check that it reaches 165°F for juicy perfection before removing it from the grill.
Step 3: Make Tomato Relish
In a separate skillet, drizzle a tablespoon of olive oil and set it over medium-high heat. Once hot, add halved cherry tomatoes, minced shallot, minced garlic, and a pinch of red pepper flakes. Sauté the mixture for about 5 minutes, or until the tomatoes begin to blister and release their juices, creating a fragrant and flavorful relish.
Step 4: Assemble Chicken with Pesto & Cheese
Spread a generous layer of basil pesto on each grilled chicken breast. Top with slices of fresh mozzarella, ensuring they cover the chicken evenly. Return the chicken to the grill on low heat, covering it with a lid or foil for about 3 minutes until the cheese melts beautifully, creating that irresistible gooey texture.
Step 5: Toast Bread
While the chicken is melting away beneath the cheese, mix melted salted butter with minced garlic. Brush this mixture generously onto the cut sides of your Italian bread buns. Toast these in the oven at 375°F (190°C) for about 3–5 minutes, or until they are golden and crispy, enhancing the sandwich experience.
Step 6: Build Sandwich
Spread any remaining basil pesto onto the warm toasted bread. Layer on the blistered tomato relish, followed by the chicken with melted mozzarella. Finish with fresh basil leaves for a burst of aromatic flavor. Assemble the sandwich by topping with the other half of the bread, ready to be devoured.

Italian Chicken Pesto Sandwich Recipe FAQs
How do I select the best chicken for this recipe?
Absolutely! When choosing chicken breasts, look for pieces that are plump and pink without any dark spots or excessive fluid in the packaging. Boneless skinless chicken breasts should feel firm to the touch. If possible, opt for organic or free-range chicken for the best flavor and texture.
What is the best way to store leftover Italian Chicken Pesto Sandwich?
You can store the assembled sandwich in an airtight container in your fridge for up to 3 days. To prevent the bread from getting soggy, try separating the components: store the chicken, relish, and bread individually and assemble the sandwich just before you’re ready to enjoy it!
Can I freeze the chicken and tomato relish?
Yes, but make sure to freeze the grilled chicken separately from the sandwich. Wrap the chicken tightly in plastic wrap or foil, then place it in a freezer bag. It should last up to 2 months. For the tomato relish, cool it completely, then pack it in an airtight container or freezer bag for up to 1 month. When you’re ready to serve, thaw and reheat the chicken gently while sautéing the relish until warmed through.
What should I do if my chicken turns out dry?
Don’t worry, you can always salvage a dry chicken! Consider making a quick sauce or glaze with additional pesto, olive oil, or chicken broth to drizzle over the sandwich. If you’re grilling, remember to check the internal temperature with a meat thermometer; chicken should reach 165°F. Keep an eye on grilling times to avoid overcooking in the future!
Can I use this recipe to make a vegetarian version?
Very! You can easily substitute the chicken with grilled vegetables such as zucchini, bell peppers, or eggplant. They soak up the delicious pesto flavor beautifully! Just grill them until tender and slightly charred. For a protein boost, consider adding some chickpeas or even a layer of roasted mushrooms.
