Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, combine 5 minced garlic cloves, 2 tbsp finely chopped fresh rosemary, 3 tbsp olive oil, 1 tsp salt, and 1/2 tsp black pepper to make a paste.
  2. Step 2: Rub the 1.5 lb pork tenderloin all over with the garlic-rosemary paste.
  3. Step 3: In a large ovenproof skillet, heat 1 tbsp olive oil over medium-high heat. Sear the pork tenderloin on all sides until browned, about 2 minutes per side.
  4. Step 4: Remove pork and add 1 large sliced yellow onion and 2 sliced Granny Smith apples to the skillet. Sauté for 5 minutes until softened and starting to caramelize.
  5. Step 5: Place the pork tenderloin on top of the apples and onions. Pour 2 tbsp apple cider vinegar and 1/2 cup chicken broth around the pork.
  6. Step 6: Transfer skillet to the oven and roast for 15-20 minutes until pork reaches an internal temperature of 145°F.
  7. Step 7: Remove from oven and let rest for 5 minutes before slicing. Serve pork slices with the roasted apples and onions spooned over.
