Preheat your oven to 375°F (190°C). Pat the chicken thighs dry with paper towels and season both sides with salt and pepper.

In a mixing bowl, combine softened cream cheese, chopped spinach, garlic powder, and Parmesan cheese. Mix until creamy.

Lay each chicken thigh flat, spoon filling into the center, and roll the thigh around the filling. Secure with toothpicks if necessary.

Place the stuffed thighs seam-side down in a greased baking dish. Drizzle with olive oil and sprinkle with Italian seasoning. Bake for 30-35 minutes.

Squeeze lemon juice over the thighs after baking and let them rest for a few minutes before serving.
