Ingredients
- 2 lbs pork loin roast
- 2 tbsp, finely chopped fresh rosemary
- 1 tbsp, finely chopped fresh thyme
- 4, minced garlic cloves
- 3 tbsp olive oil
- 1 1/2 tsp salt
- 1 tsp black pepper
- 2 lbs, peeled and cubed russet potatoes
- 4 tbsp unsalted butter
- 1/2 cup whole milk
- 3, peeled garlic cloves for mashed potatoes
- 1 tsp salt for potatoes
Instructions
- Step 1: Preheat oven to 375°F. In a small bowl, combine 3 tbsp olive oil, 4 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 tbsp chopped fresh thyme, 1 1/2 tsp salt, and 1 tsp black pepper to form an herb paste.
- Step 2: Pat dry the 2 lb pork loin roast and rub the herb paste evenly all over the surface. Place pork on a roasting rack in a baking pan.
- Step 3: Roast pork loin in the preheated oven for 50-60 minutes, or until an internal temperature of 145°F is reached, turning halfway through for even browning.
- Step 4: While the pork roasts, place 2 lbs peeled and cubed russet potatoes along with 3 peeled garlic cloves into a large pot. Cover with cold water and add 1 tsp salt.
- Step 5: Bring potatoes and garlic to a boil over high heat, then reduce to medium and simmer for 15-18 minutes until potatoes are fork-tender.
- Step 6: Drain potatoes and garlic, then return to pot. Add 4 tbsp unsalted butter and 1/2 cup whole milk, mashing until smooth and creamy.
- Step 7: Remove pork from oven, tent with foil, and let rest for 10 minutes before slicing. Serve sliced pork loin with garlic mashed potatoes.
