Instructions

  1. Step 1: Preheat oven to 400°F. Butterfly 1 lb pork tenderloin by slicing lengthwise down the center, stopping 1/2 inch from the edge, then open it like a book.
  2. Step 2: In a bowl, combine 4 oz softened cream cheese, 1/4 cup grated parmesan cheese, 1 tbsp chopped rosemary, 1 tbsp chopped thyme, and 2 minced garlic cloves until well mixed.
  3. Step 3: Spread the cheese and herb mixture evenly over the inside of the pork tenderloin, then roll it up tightly and secure with kitchen twine.
  4. Step 4: Rub the outside of the pork with 2 tbsp olive oil, 1 tsp salt, and 1/2 tsp black pepper.
  5. Step 5: Place the pork on a baking sheet and roast in the preheated oven for 25-30 minutes until internal temperature reaches 145°F.
  6. Step 6: Let rest for 5 minutes before slicing into 1-inch medallions and serving.
