Step 1

Preheat the oven to 400°F and lightly grease a 9x13 inch baking dish with butter or cooking spray. Set aside.

Step 2

Cut the chicken breasts in half horizontally to create four cutlets. Pound the thicker ends with a rolling pin so they’re all of even thickness.

Step 3

In a large bowl, whisk 1 tablespoon of olive oil with minced garlic, Italian seasoning, salt and pepper. Add the chicken, toss to coat, then cover and chill in the fridge for 15-30 minutes.

Step 4

Heat the remaining 1 tablespoon olive oil in a large skillet over medium heat. Add the spinach and cook, stirring frequently, until wilted, about 2-3 minutes. Set aside.

Step 5

In a medium bowl, beat the cream cheese until smooth. Add the wilted spinach, 1/2 cup mozzarella, and Parmesan (if using). Mix until smooth.

Step 6

Take the chicken out of the marinade and let the excess drip off. If desired, sear the chicken in the skillet for 1-2 minutes per side. Then, arrange the meat in a single layer in the baking dish.

Step 7

Spread the spinach and cream cheese mixture over the meat, then sprinkle the remaining mozzarella cheese over the top.

Step 8

Bake for 20-30 minutes, until the chicken is cooked and the cheese is melted and lightly browned. Let stand for 5 minutes before serving. Enjoy!
