This easy and tender pork tenderloin is marinated in balsamic vinegar and rosemary and seared and baked in cast iron skillet.

Ingredients

Units Scale
  • 1 lb pork tenderloin, silver skin removed
  • ~ 1 Tbsp vegetable oil
  • 1 1/2 Tbsp balsamic vinegar
  • 1/4 tsp garlic powder
  • 1 Tbsp fresh rosemary, chopped
  • 1/2 tsp salt
  • pinch black pepper

Instructions

  • Preheat oven to 375F.
  • Mix balsamic vinegar, garlic powder, rosemary, salt, and pepper together in a small bowl.  
  • Rub marinade over pork tenderloin and let sit 20 minutes at room temperature.  Flip pork at 10 minutes to get marinade on both sides.
  • Bring a heavy bottomed & oven proof pan (cast iron works best) to medium high heat.  
  • Add enough vegetable oil  to lightly coat the bottom of the pan.  Turn your oven vent on – there may be a fair amount of smoke.  Grab a splatter guard as well, if you’ve got one.  
  • When the oil is hot, add the tenderloin and pan fry ~ 2 minutes on two sides (there are usually 3 sides for a tenderloin).
  • Flip the pork tenderloin to the third side and immediately transfer to an oven.
  • Cook 12-15 minutes or until internal temperature reaches 145F.  
  • Tent loosely and let sit 10 minutes before slicing / serving
  • Add salt to taste. Happy eating!  Beckie

Notes

  • You may need to sear the tenderloins in batches if the pan is not big enough.  It's important to sear and not steam the meat.
  • The pork tenderloin will be easier to slice when the meat has cooled at least 15 minutes.
