Pat the pork tenderloin dry with paper towels. Season generously with salt and black pepper.

Heat olive oil in a large skillet over medium-high heat. Sear the pork tenderloin on all sides until browned, about 2-3 minutes per side. This step helps to lock in juices and add flavor.
While the pork is searing, prepare the glaze. In a medium bowl, whisk together the balsamic vinegar, brown sugar, Dijon mustard, Worcestershire sauce, garlic powder, onion powder, and dried thyme until well combined.

Carefully transfer the seared pork tenderloin to the slow cooker. Pour the prepared glaze evenly over the pork.

Cover the slow cooker and cook on low for 3-4 hours, or on high for 2-3 hours, or until the internal temperature of the pork reaches 145°F (63°C) when measured with a meat thermometer.

Once cooked, carefully remove the pork tenderloin from the slow cooker and transfer it to a cutting board. Tent loosely with foil and let it rest for 10 minutes. This allows the juices to redistribute, ensuring a tender and moist result.

While the pork is resting, prepare the thickened glaze. In a small bowl, whisk together the cornstarch and cold water to create a slurry. Pour the liquid from the slow cooker into a small saucepan. Bring to a simmer over medium heat.

Gradually whisk the cornstarch slurry into the simmering liquid in the saucepan. Continue to whisk and simmer for 1-2 minutes, or until the glaze has thickened to your desired consistency. Remove from heat.

Slice the rested pork tenderloin into 1/2-inch thick medallions. Arrange on a serving platter.

Spoon the warm balsamic glaze generously over the sliced pork. Garnish with fresh chopped thyme before serving.
