01 - Preheat oven to 375°F (190°C). Line a baking dish with parchment paper or lightly grease to prevent sticking.
02 - In a skillet, heat 1 tablespoon olive oil over medium heat. Sauté minced garlic and chopped spinach until wilted, approximately 2 minutes. Remove skillet from heat.
03 - In a mixing bowl, thoroughly combine sautéed spinach, cream cheese, crumbled feta cheese, and chopped dried cranberries. Season the mixture with 1/4 teaspoon each of salt and black pepper, mixing until smooth.
04 - With a sharp knife, carefully cut a deep pocket into the thickest side of each chicken breast without slicing all the way through.
05 - Evenly spoon the prepared spinach-cranberry filling into each chicken breast pocket, securing with toothpicks as needed to hold the filling in place.
06 - In a separate small bowl, mix paprika, dried thyme, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Brush the exterior of each stuffed chicken breast with 1 tablespoon olive oil, then generously sprinkle with the seasoning blend.
07 - Place the seasoned, stuffed chicken breasts in the prepared baking dish in a single layer.
08 - Transfer to oven and bake for 25 to 30 minutes, until the chicken is fully cooked, the juices run clear, and an internal temperature of 165°F (74°C) is reached.
09 - Carefully remove toothpicks, let chicken rest for 5 minutes before slicing and serving.
