Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). In a small bowl, combine 1 tsp lemon zest, 2 tbsp lemon juice, 1 tbsp chopped fresh thyme, 2 minced garlic cloves, 2 tbsp olive oil, 1 tsp salt, and 1/2 tsp black pepper to create a marinade.
  2. Step 2: Rub the marinade all over 1.5 lbs trimmed pork tenderloin and let it rest at room temperature for 10 minutes.
  3. Step 3: Place the pork tenderloin on a rimmed baking sheet and roast in the preheated oven for 20-25 minutes until an internal temperature of 145°F is reached, turning halfway through for even browning.
  4. Step 4: While the pork roasts, heat 1 tbsp olive oil in a large skillet over medium heat. Add 2 minced garlic cloves and 1 lb trimmed green beans, sautéing for 5-7 minutes until green beans are tender-crisp and garlic is fragrant.
  5. Step 5: Season green beans with salt to taste and 1/4 tsp red pepper flakes if desired.
  6. Step 6: Remove pork from oven and let rest for 5 minutes before slicing. Serve sliced pork alongside garlic green beans.
