Slice the pork into medallions and lie flat on the cutting board or on a plate.
1 pound pork tenderloin
In a small bowl, mix together the salt, thyme, rosemary, paprika, garlic powder, and black pepper. Sprinkle this mixture evenly on both sides of the medallions and gently press it into the pork.
1 teaspoon kosher salt, 1 teaspoon dried thyme, 1 teaspoon dried rosemary, 1/2 teaspoon sweet paprika, 1/4 teaspoon garlic powder, 1/4 teaspoon black pepper
Warm olive oil and melt 1/2 Tablespoon of butter together in a large skillet set over medium-high heat. When hot, add half of the medallions and cook for 2-3 minutes, until well-browned on the bottom. Flip to the other side and cook for 3-4 minutes more, until they reach an internal temperature of 145°F.
1 Tablespoon olive oil, 1 Tablespoon butter
Remove pork to a plate and set aside. Add another drizzle of olive to the pan if it looks dry, then repeat with the other half of the medallions.
Once all the pork is cooked through, reduce the heat to medium and slowly pour in the broth. Scrape to release browned bits from the bottom of the pan, and bring the sauce to a simmer.
1/2 cup low sodium chicken broth
While the sauce bubbles, stir in the remaining 1/2 Tablespoon butter plus the balsamic vinegar. Let the butter melt, then stir well and keep simmering the sauce until it is as thick as you like.
1 Tablespoon balsamic vinegar
Return pork to the pan and spoon sauce on top to warm. Sprinkle with a few leaves of fresh thyme or parsley, and serve right away.
