01 - Preheat oven to 375°F (190°C). Line a baking dish with parchment paper or lightly grease the surface.
02 - In a skillet over medium heat, warm 1 tablespoon olive oil. Sauté minced garlic and chopped spinach until wilted, about 2 minutes. Remove from heat.
03 - Combine sautéed spinach, softened cream cheese, crumbled feta, and chopped cranberries in a mixing bowl. Season with 1/4 teaspoon salt and 1/4 teaspoon pepper. Mix until thoroughly incorporated.
04 - Using a sharp knife, carefully create a deep pocket in the thickest part of each chicken breast without cutting all the way through.
05 - Fill each chicken pocket evenly with the spinach and cranberry mixture. Secure the edges with toothpicks if necessary.
06 - In a small bowl, blend paprika, dried thyme, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Brush chicken breasts with 1 tablespoon olive oil, then evenly sprinkle the seasoning mixture over all sides.
07 - Arrange the stuffed chicken breasts in the prepared baking dish. Bake for 25 to 30 minutes, or until the chicken is fully cooked and juices run clear. Internal temperature should reach 165°F (74°C).
08 - Remove toothpicks and allow chicken to rest for 5 minutes before slicing and serving.
