Preheat oven to 375°F. Line a sheet pan with parchment paper.

Butterfly the pork loin: slice horizontally through the center without cutting all the way through. Open it like a book.

Cover with plastic wrap and pound to an even thickness (½–¾ inch).

In a bowl, mix cream cheese, bacon, spinach, cheddar, and green onions.

Spread filling evenly over the pork, leaving a 1-inch border.

Roll tightly, seam-side down. Tie with butcher’s twine if needed.

Season outside with garlic powder, onion powder, paprika, salt, and pepper.

Bake 50–60 minutes, or until a meat thermometer reads 145°F.

Rest 10 minutes before slicing for juicy, tender results.
