Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a small bowl, mix garlic, rosemary, mustard, kosher salt, and olive oil to make a paste.
2 cloves garlic, 1 tablespoon fresh rosemary, 1 tablespoon mustard, 1 teaspoon kosher salt, 1 tablespoon olive oil
With a sharp knife remove as much sinew from the tenderloin as possible.
1 ½ pound pork tenderloin
Spoon the paste onto the tenderloin and rub on all sides.
Wrap the bacon strips by overlapping them slightly, so they stay secure. You can use toothpicks to secure the bacon, if needed.
6 strips bacon
Mix the maple syrup and balsamic vinegar in a small bowl, then using a pastry brush, brush on the mixture all over the wrapped tenderloin.
1 teaspoon maple syrup, 1 tablespoon balsamic vinegar
Place the prepared tenderloin on the baking sheet and bake for 20-25 minutes until the internal temperature reads 150°F for the juiciest pork. If the bacon is not crisp enough, finish it under the broiler for 3-5 minutes or as long as needed.
Let it rest for at least 10 minutes before slicing. Serve with the potatoes or your favorite sides.
