Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, combine 2 tbsp olive oil, 4 minced garlic cloves, 1 tbsp chopped rosemary, 1 tbsp chopped thyme, 1 tsp sea salt, and 1/2 tsp black pepper to create a herb marinade.
  2. Step 2: Rub this marinade evenly over 1.5 lbs pork tenderloin. Let it rest at room temperature for 10 minutes.
  3. Step 3: Toss 2 sliced apples and 1 sliced fennel bulb with remaining 1 tbsp olive oil, 1/2 tsp sea salt, 1/2 tsp black pepper, and 1 tbsp apple cider vinegar. Arrange apples and fennel in a roasting pan.
  4. Step 4: Place the pork tenderloin on top of the vegetables and roast for 25-30 minutes until internal temperature reaches 145°F.
  5. Step 5: Remove from oven and tent with foil for 5 minutes before slicing the pork. Serve the sliced pork alongside the roasted apples and fennel.
