Pre-heat oven to 375℉.
Season pork tenderloin with salt, black pepper, garlic powder and dried rosemary.
Heat skillet and sear pork tenderloin until it is slightly brown on the outsides. Remove from heat promptly. Pork does not have to be cooked through.
Next, wrap seared pork tenderloin in bacon: Line uncooked bacon next to each other on a cutting board. Bacon can be overlapped slightly or lined very closely next to each other with as little gaps as possible. Place pork tenderloin across and perpendicular to the strips of bacon, then fold strips of bacon over to cover the pork tenderloin. Gently roll pork tenderloin with strips of bacon until pork is fully wrapped in strips of bacon.
Place bacon wrapped pork tenderloin onto a baking dish, then brush the top with maple syrup.
Bake for 25-30 minutes, or until the internal temperature of the thickest part of pork tenderloin is at at least 145℉.
Remove pork from oven. Let it sit for 5 minutes, then slice into smaller pieces.
Serve and enjoy!
