Preheat your oven to 375°F (190°C). This step is crucial for ensuring that your Chicken Roll Ups cook evenly.
In a mixing bowl, combine the garlic powder, smoked paprika, Italian seasoning, kosher salt, and ground black pepper. Sprinkle this seasoning mixture evenly over the thinly sliced chicken breasts.
Take the package of Boursin cheese and spread an even layer over each seasoned chicken slice. Make sure to cover the entire surface to maximize flavor.
Sprinkle freshly shredded mozzarella cheese over the Boursin cheese layer. This will add a melty, gooey texture to each roll-up.
Starting from one end, carefully roll each chicken slice tightly. Secure the roll with a toothpick if necessary to ensure they stay together during baking.
Lightly spray your baking dish with cooking spray and place the rolled chicken seam-side down in the dish. Bake in the preheated oven for about 25-30 minutes, or until the chicken is cooked through and the cheese is bubbly.
Remove the Chicken Roll Ups from the oven and let them rest for a few minutes. This helps the cheese set slightly. Serve warm with your favorite sides or a fresh salad for a complete meal.
