Why You’ll Love This Pesto Grilled Chicken Sandwich with Mozzarella

What makes this sandwich stand out is the balance of flavors and textures. The pesto coats the chicken with fresh basil, garlic, and Parmesan notes, while the mozzarella adds a creamy, mild counterpoint that keeps every bite luscious. The tomatoes bring a gentle sweetness and acidity that brightens the whole sandwich, and arugula delivers a peppery crunch. Toasted bread provides a toasty foundation that holds up beautifully, so every bite is cohesive and satisfying. Best of all, the prep is simple and forgiving, so you can swap in what you have on hand without missing a beat.

Ingredients for Pesto Grilled Chicken Sandwich with Mozzarella

• 2 skinless chicken breasts (boneless) — the protein backbone that keeps the sandwich hearty.
• 3 tablespoons pesto — the star flavor, delivering herbaceous brightness and a hint of garlic and cheese.
• 4 slices fresh mozzarella — creamy, mild cheese that melts into the warm chicken and bread.
• 6 cherry tomatoes, halved — juicy bursts that add sweetness and acidity.
• 1 cup arugula or baby spinach — a peppery, fresh green for crunch and color.
• 2 ciabatta rolls or baguette halves — sturdy, crusty bread that stands up to juicy fillings.
• 1 tablespoon olive oil — for a light sear and toasting the bread.
• to taste salt — enhances all components; use conservatively on the chicken if your pesto is salty.
• to taste black pepper — a subtle bite that ties the flavors together.

Step-by-Step Guide to Making Pesto Grilled Chicken Sandwich with Mozzarella

1. Pat the chicken breasts dry and season lightly with salt and pepper. Rub 1 tablespoon of pesto over each breast to infuse flavor from the start.
2. Heat a grill pan or skillet over medium-high heat and brush with a little olive oil. Grill the chicken for 5–6 minutes per side, until cooked through and nicely browned. Let it rest for a few minutes before slicing to keep the juices in.
3. While the chicken rests, lightly toast the bread slices until golden. A quick toast adds needed crunch and helps hold the fillings together.
4. Assemble the sandwiches: layer arugula on the bottom, then sliced chicken, tomatoes, and mozzarella. If you prefer extra cheese, add another mozzarella slice on top.
5. Spread a thin layer of pesto on the inside of the top bread piece. Close the sandwiches and, if you’d like, place them back on the grill for 1–2 minutes to gently melt the mozzarella.
6. Slice in half and serve immediately. Optional: a light drizzle of balsamic glaze adds a touch of sophistication and sweetness that pairs beautifully with the pesto.

Timing & Preparation Details

• Active prep time: about 15 minutes. You can multitask by preheating the grill while you season the chicken and prepare the toppings.

Frequently Asked Questions

Can I make this ahead of time?

Yes. You can grill the chicken and prepare toppings in advance, then assemble the sandwiches just before serving. If you’re short on time, you can keep the chicken sliced and store it in the fridge, ready to go with pesto, tomatoes, mozzarella, and bread when you’re ready to assemble.

What can I swap for mozzarella?

Any mild, meltable cheese works. Provolone or fontina are great options. Fresh mozzarella has a softer melt, while sliced mozzarella melts nicely and gives a more uniform texture.

Is this suitable for a bread-free option?

Yes. You can serve the chicken and pesto over a bed of greens or in a lettuce wrap for a lighter, low-carb version that still captures the pesto flavors and juicy chicken.

Ingredients

  

• 2 skinless chicken breasts (boneless)
• 3 tablespoons pesto
• 4 slices fresh mozzarella
• 6 cherry tomatoes, halved
• 1 cup arugula or baby spinach
• 2 pieces ciabatta rolls or baguette halves
• 1 tablespoon olive oil
• to taste salt
• to taste black pepper

Instructions

 

• Pat the chicken breasts dry and season lightly with salt and pepper. Rub 1 tablespoon of pesto over each breast for a quick flavor boost.
• Heat a grill pan or skillet over medium-high heat and brush with a little olive oil. Grill the chicken 5–6 minutes per side, or until fully cooked through (internal temperature 165°F/74°C). Let rest for a few minutes, then slice thinly.
• While the chicken rests, lightly toast the bread until golden. If you like a little extra crunch, brush the cut sides with a touch more olive oil before toasting.
• Assemble each sandwich by layering arugula, sliced chicken, tomatoes, and mozzarella on the bottom half. If you’re using whole mozzarella slices, you can crown the chicken with one more slice for extra gooey goodness.
• Spread a thin layer of pesto on the inside of the top crust, add a light sprinkle of salt and pepper, then close the sandwich. If you prefer melted cheese all the way through, you can place the assembled sandwich back on the grill for 1–2 minutes to melt the mozzarella.
• Slice in half and serve immediately. Optional: drizzle with a tiny bit of balsamic glaze for a tangy finish.
