Ingredients

Scale

Main Ingredients:

  • 4 boneless, skinless chicken breasts
  • 4 cups fresh spinach
  • 1 ½ cups shredded mozzarella cheese

Dairy Ingredients:

  • 8 ounces cream cheese, softened
  • ½ cup sour cream

Seasonings and Additions:

  • 2 garlic cloves, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon paprika
  • ½ teaspoon onion powder
  • 1 tablespoon olive oil

Instructions

  1. Preheat the oven to 375°F and coat a 9×13 inch baking dish with cooking spray to prevent sticking.
  2. Combine 1 teaspoon salt, ½ teaspoon black pepper, ½ teaspoon paprika, and ½ teaspoon onion powder in a small bowl for the chicken seasoning.
  3. Rub the 4 chicken breasts with the spice mixture, ensuring each piece is evenly coated.
  4. Heat 1 tablespoon olive oil in a large skillet over medium-high heat for 2 minutes until shimmering.
  5. Sear the chicken breasts for 3-4 minutes per side, creating a golden brown exterior that seals in moisture.
  6. Transfer the chicken to a clean plate and let it rest momentarily.
  7. In the same skillet, add 4 cups fresh spinach and cook for 2-3 minutes until it wilts and shrinks.
  8. Mix 8 ounces softened cream cheese, ½ cup sour cream, and 2 minced garlic cloves in a separate mixing bowl.
  9. Fold the cooked spinach into the creamy mixture until thoroughly combined.
  10. Spread half the spinach mixture across the bottom of the prepared baking dish.
  11. Arrange the seared chicken breasts directly on top of the spinach layer.
  12. Cover the chicken with the remaining spinach mixture, ensuring complete coverage.
  13. Sprinkle 1 ½ cups shredded mozzarella cheese over the entire casserole.
  14. Bake uncovered at 375°F for 25-30 minutes until the chicken reaches an internal temperature of 165°F and the cheese turns golden and bubbly.

Notes

  • Seasoning is key to building deep flavor, so take time to generously coat the chicken with spices before searing.
  • Allow the chicken to rest for a few minutes after searing to help retain its juiciness and prevent drying out during baking.
  • For a lighter version, swap full-fat cream cheese and sour cream with their low-fat or Greek yogurt alternatives to reduce calories.
  • Ensure the chicken reaches an internal temperature of 165°F to guarantee safe cooking, using a meat thermometer for precise results.
