Instructions

  1. Step 1: Preheat oven to 400°F. Butterfly 1.5 lbs pork tenderloin by slicing lengthwise almost through, then open flat. Season inside and outside with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Evenly spread 1 cup chopped fresh spinach and 4 oz shredded sharp cheddar cheese over the inside of the pork. Roll tightly and secure with kitchen twine every 2 inches.
  3. Step 3: Heat 2 tbsp olive oil in an oven-safe skillet over medium-high heat. Sear the pork roll on all sides for 3-4 minutes until golden brown.
  4. Step 4: Transfer skillet to oven and roast pork for 20-25 minutes until internal temperature reaches 145°F. Remove pork and tent with foil to rest.
  5. Step 5: In the same skillet, melt 4 tbsp unsalted butter over medium heat. Add 3 minced garlic cloves and 1 tsp fresh thyme leaves, cooking for 1-2 minutes until fragrant. Stir in 1 tbsp fresh lemon juice, then pour sauce over sliced pork before serving.
