If you are looking for a warm sandwich that combines juicy chicken, melted cheese, fresh vegetables, and bold Italian-inspired flavor, this Grilled Chicken Panini Sandwich is an excellent recipe to make. Tender seasoned chicken is layered with basil pesto, Provolone cheese, ripe tomatoes, roasted red peppers, and baby spinach between sturdy Italian bread, then pressed until beautifully crisp and golden.
This recipe is perfect for lunch, quick dinners, weekend meals, meal prep, or anytime you want something more satisfying than an ordinary cold sandwich. The pesto gives every bite a fresh garlic-and-basil flavour, while roasted peppers add sweetness and the melted cheese holds everything together.
One of the best things about homemade chicken paninis is how easy they are to customize. You can add bacon, avocado, caramelized onions, mushrooms, mozzarella, spicy peppers, or different sauces depending on what you have available.
Why You’ll Love This Grilled Chicken Panini Sandwich
This easy panini combines a crispy exterior with a warm, juicy, cheesy center.
The chicken is seasoned with garlic, oregano, paprika, and black pepper before being grilled until golden, giving the sandwich much more flavor than simply using plain chicken.
Basil pesto works as both a flavorful spread and a complement to the Provolone, tomatoes, roasted peppers, and spinach.
You also do not absolutely need a panini press. A heavy skillet and a second pan can create a similar pressed, toasted finish at home. The linked recipe likewise provides both panini-press and stovetop methods.

How to Make Grilled Chicken Panini Sandwiches
1. Prepare the Chicken
Place the chicken cutlets on a cutting board and pat them thoroughly dry with paper towels.
If using whole chicken breasts rather than cutlets, slice them horizontally into thinner pieces.
You can also gently pound the chicken to approximately ½ inch thick.
Evenly sized chicken cooks more quickly and consistently.
2. Season the Chicken
Place the chicken in a medium bowl.
Add the olive oil, salt, black pepper, garlic powder, oregano, onion powder, paprika, red pepper flakes if using, and lemon juice.
Toss until every piece is thoroughly coated.
Allow the chicken to rest for approximately 10–15 minutes while you prepare the other ingredients.
3. Heat the Grill or Grill Pan
Preheat an outdoor grill, cast-iron grill pan, or heavy skillet over medium-high heat.
The cooking surface should be hot before the chicken is added.
A properly heated pan helps the exterior brown quickly without requiring excessive cooking time.
4. Grill the Chicken
Place the chicken on the hot grill or skillet.
Cook without disturbing for approximately 4–5 minutes on the first side.
Flip and continue cooking for another 2–4 minutes, depending on thickness.
The original linked recipe uses a similar quick grilling method for chicken cutlets.
Check the thickest part with an instant-read thermometer.
Chicken should reach 165°F (74°C) for food safety.
Transfer the cooked chicken to a clean plate.
Allow it to rest for approximately 5 minutes before slicing.
5. Prepare the Bread
Slice each ciabatta roll horizontally.
If using a large Italian loaf, cut it into four sandwich-sized portions and slice each horizontally.
Sturdy breads such as ciabatta or Italian bread work particularly well because they can handle the filling and pressure without falling apart; the source recipe specifically recommends dense Italian-style bread and also notes ciabatta as an alternative.
6. Add the Pesto
Spread approximately 1–1½ tablespoons of basil pesto over the inside of each sandwich.
You can spread pesto on both pieces of bread for stronger flavor or only on the bottom for a lighter version.
Avoid using an excessive amount, which can make the sandwich oily.
7. Add the First Cheese Layer
Place one slice of Provolone over the bottom half of each roll.
Starting with cheese creates a barrier between the bread and some of the wetter ingredients.
It also helps hold the chicken in place as the cheese melts.
8. Add the Chicken
Slice the rested grilled chicken into strips.
Arrange the chicken over the cheese.
Divide it evenly among the four sandwiches.
Try to cover the bread from edge to edge so every bite contains chicken.
9. Add the Tomatoes and Roasted Peppers
Place thin tomato slices over the chicken.
Pat the roasted red peppers thoroughly dry before adding them.
This is especially important because excess liquid can make the bread soggy; the linked recipe similarly recommends drying the peppers before assembly.
Arrange the pepper strips over the tomatoes.
Season lightly with freshly ground black pepper.
10. Add the Spinach and More Cheese
Add a small handful of baby spinach to each sandwich.
Top with the remaining Provolone.
Having cheese near both sides helps the sandwich hold together after pressing.
Add fresh basil, red onion, or other optional toppings at this stage if desired.
11. Close the Sandwiches
Place the top pieces of bread over the filling.
Press down gently with your hands.
Brush or spray a light coating of olive oil over the exterior of the bread.
You only need enough to help create a crisp, golden crust.
12. Cook in a Panini Press
Preheat the panini press according to the manufacturer’s directions.
Place the sandwiches inside.
Close the press gently.
Cook for approximately 3–5 minutes, or until the bread is deeply golden and crisp and the cheese is completely melted. This timing follows the general method used by the linked recipe.
Avoid pressing so aggressively that all of the filling is pushed out.
13. Stovetop Method Without a Panini Press
Heat a large skillet or grill pan over medium heat.
Place one or two sandwiches in the skillet.
Put another clean heavy skillet over the top and press gently.
Cook for approximately 2–3 minutes.
Carefully flip.
Press again and cook for another 2–3 minutes, or until both sides are crisp and the cheese is melted.
Reduce the heat if the bread browns too quickly.
14. Rest and Slice
Transfer the cooked paninis to a cutting board.
Allow them to rest for approximately 2 minutes.
This gives the melted cheese time to settle slightly.
Slice each sandwich diagonally.
Serve immediately while the bread is crisp and the cheese is warm and gooey.
What to Serve With Grilled Chicken Panini Sandwiches
Tomato soup is one of the best pairings for this sandwich. The bright tomato flavor works beautifully with pesto, chicken, and melted cheese.
Roasted red pepper soup, vegetable soup, or minestrone are also excellent options. Soup pairings are also suggested with the original linked panini.
For a lighter meal, serve the panini with a Caesar salad, garden salad, cucumber salad, or arugula salad.
French fries, sweet potato fries, potato wedges, chips, or roasted potatoes work well when you want something more substantial.
Fresh fruit or a simple tomato salad makes an easy lunch combination.
Tips for the Best Grilled Chicken Panini Sandwich
Use chicken cutlets of similar thickness so they cook evenly.
Pat the chicken dry before seasoning.
Do not overcook the chicken. A thermometer is the easiest way to verify it has reached the safe 165°F temperature without continuing to cook it unnecessarily.
Use sturdy bread such as ciabatta, focaccia, sourdough, or Italian bread.
Pat tomatoes and roasted peppers dry if they contain excessive moisture.
Use cheese that melts well. Provolone is excellent, but mozzarella, fontina, smoked Gouda, or Gruyère can also work; several of these alternatives are suggested by the source recipe.
Do not overload the sandwiches.
Apply only a light coating of oil to the outside.
Use medium heat when cooking without a panini press so the cheese has enough time to melt before the bread burns.
Serve immediately for the crispiest texture.
Easy Recipe Variations

Caprese Chicken Panini

Chicken Avocado Panini
Add thin avocado slices after the grilled chicken.
Mushroom Provolone Chicken Panini

Mediterranean Chicken Panini

Garlic Parmesan Chicken Panini

Replace the grilled chicken with sliced roasted turkey for a quicker version.
How to Store Leftovers
Paninis are best immediately after pressing because that is when the bread is crispest.
If you have leftovers, allow them to cool before storing.
Wrap each sandwich tightly or place it in an airtight container.
Refrigerate for up to 3–4 days, assuming the cooked chicken and other perishable ingredients have been handled and chilled properly.
For best results, reheat the sandwich in a skillet, panini press, oven, or air fryer.
A panini press can usually restore much of the original crisp texture.
If using an oven, heat at approximately 350°F (175°C) until warmed through and the cheese melts again.
Avoid microwaving when possible because it tends to soften the bread.
For meal prep, the better approach is to store the cooked chicken separately and assemble fresh sandwiches when needed.
