Preheat your oven to 200°C (390°F) and gather all your ingredients.
Using a sharp knife, carefully cut a horizontal pocket into each chicken breast, making sure not to cut all the way through.
In a mixing bowl, combine softened cream cheese, chopped herbs, lemon zest, lemon juice, smoked paprika, salt, and pepper. Stir until smooth and fragrant.
Stuff each chicken breast with the herb and cream cheese mixture, pressing gently to seal the filling inside. Use toothpicks if needed to keep it closed.
Heat oil in a skillet over medium-high heat until shimmering and slightly fragrant. Sear the stuffed chicken breasts for about 3-4 minutes per side, until golden brown and crispy.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Remove the chicken from the oven, let it rest for 5 minutes to retain juices, then slice to reveal the oozing, flavorful filling inside.
Serve hot, sliced into thick pieces, allowing the creamy filling to spill out beautifully with each cut.
