INGREDIENTS
  

  • 2 large boneless, skinless chicken breasts, about 1 pound
  • 2 tablespoons olive oil, divided
  • 3 cloves garlic, minced or pressed
  • 1 tablespoon Italian seasoning
  • ¼ teaspoon salt, or to taste
  • ½ teaspoon black pepper, or to taste
  • 7-8 ounces fresh spinach
  • 8 ounces cream cheese, softened
  • 1 cup shredded Mozzarella cheese, divided
  • ½ cup Parmesan cheese
  • fresh thyme leaves for servings

INSTRUCTIONS
 

  • Preheat your oven to 400°F and grease a 9x13 inch baking dish with butter or cooking spray. Set aside.
  • Slice the chicken breasts in half lengthwise to make four thinner pieces. Use a rolling pin to flatten the thicker parts so they’re even.

  • In a big bowl, mix 1 tablespoon of olive oil, minced garlic, Italian seasoning, salt, and pepper. Add the chicken, toss it to coat, cover, and chill in the fridge for 15-30 minutes (Optional).
    2 tablespoons olive oil, 1 tablespoon Italian seasoning, ¼ teaspoon salt, ½ teaspoon black pepper, 3 cloves garlic
  • Heat 1 tablespoon of olive oil in a pan over medium heat. Cook the spinach for 2-3 minutes, stirring, until it wilts. Set it aside.

  • In a separate bowl, beat the cream cheese until smooth. Stir in the spinach, ½ cup of mozzarella, and Parmesan (optional). Note: Before adding the spinach, squeeze any excess moisture.

  • Take the chicken out of the marinade and shake off any extra. Lay the chicken in the baking dish in a single layer.
  • Spread the cream cheese and spinach mix on top of the chicken. Sprinkle the remaining mozzarella on top.
  • Bake for 25-30 minutes until the chicken is done and the cheese is bubbly and golden. Let it rest for 5 minutes before serving. You can top it with fresh thyme if you want. Enjoy!
