Preheat your oven to 375°F (190°C).
Ensure the oven is hot and ready when you finish preparing the tenderloin.
Combine honey, soy sauce, garlic powder, brown sugar, balsamic vinegar, water, and black pepper in a bowl.
Whisk these ingredients together until the sugar is dissolved and the mixture is smooth.
Heat olive oil in an oven-safe skillet over medium heat.
Sear the pork tenderloin until all sides are browned, which should take about 5 minutes in total.
Pour the glaze mixture over the seared tenderloin.
Transfer the skillet to the preheated oven and roast the pork for about 25 minutes or until the internal temperature reaches 145°F (63°C).
Remove the tenderloin from the oven and let it rest for 5-10 minutes.
This resting period helps the juices redistribute for a juicy and tender result.
