01 - Preheat your oven to 375°F. Lightly grease a baking dish with cooking spray or olive oil to prevent sticking.
02 - In a small bowl, whisk together olive oil, garlic powder, thyme, salt, and pepper. Brush both sides of each turkey cutlet with the seasoned oil mixture, ensuring even coverage.
03 - In a separate bowl, combine breadcrumbs, celery, onion, parsley, melted butter, chicken broth, sage, rosemary, black pepper, and salt. Mix thoroughly until the stuffing holds together when pressed.
04 - Lay each seasoned turkey cutlet flat on a clean surface. Place a quarter of the stuffing mixture at one end of each cutlet and roll up tightly, enclosing the filling. Secure with toothpicks if necessary to hold the shape.
05 - Arrange the roll ups seam-side down in the prepared baking dish. Pour 1 cup chicken broth around the roll ups, avoiding direct pouring over the meat. Cover tightly with foil and bake for 25 minutes. Remove foil and continue baking for an additional 15 minutes, or until turkey is fully cooked through and golden brown. Remove toothpicks before serving.
