Ingredients

Instructions

  1. Step 1: In a bowl, whisk together 4 tbsp olive oil, 3 tbsp lemon juice, 2 tbsp chopped fresh rosemary, 4 minced garlic cloves, 2 tsp salt, and 1 tsp black pepper to create a marinade.
  2. Step 2: Place 8 lamb rib chops in a shallow dish and pour the marinade over them. Cover and refrigerate for at least 1 hour, preferably 3 hours, turning occasionally.
  3. Step 3: Meanwhile, place 2 lbs peeled and quartered russet potatoes in a large pot and cover with cold water. Bring to a boil over high heat and cook for 15-20 minutes until potatoes are fork-tender. Drain well.
  4. Step 4: Mash the potatoes with 4 tbsp butter and 1/2 cup whole milk until smooth and creamy. Season with salt and pepper to taste.
  5. Step 5: Preheat grill or grill pan to medium-high heat. Remove lamb chops from marinade and grill for 4-5 minutes per side for medium-rare, or longer to desired doneness.
  6. Step 6: Let the lamb rest for 5 minutes before serving alongside the garlic mashed potatoes.
