Preheat your oven to a warm, inviting 375°F (190°C). Lightly grease a baking dish with a teaspoon of olive oil and set it aside. We want the chicken to release a little steam and stay juicy, not dry out on the edges.
Prepare the chicken breasts by carefully butterflying them or pounding to a uniform thickness. This helps them cook evenly and makes space for a generous filling.
In a skillet over medium heat, add a drizzle of olive oil. Sauté the minced garlic for about 30 seconds until fragrant, then add the spinach and cook just until wilted. Remove from heat.
In a small bowl, combine the sun-dried tomatoes, feta, cream cheese, oregano, smoked paprika, and a pinch of salt and pepper. Mix until the filling is cohesive and creamy. Fold in the sautéed spinach mixture.
Spoon the filling onto each prepared chicken breast. Gently fold or roll the chicken around the filling so it stays enclosed. If needed, secure with a toothpick or kitchen twine.
Season the outside of the stuffed chicken lightly with salt and pepper. Place seam-side down in the prepared baking dish.
Bake in the preheated oven for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the filling is bubbling gently. If you’d like a lightly browned top, switch the oven to broil for the last 1-2 minutes of cooking, watching closely.
Let the chicken rest for 5 minutes before slicing. This helps the juices redistribute, ensuring every bite stays moist and flavorful.
