Ingredients

Instructions

  1. Step 1: In a bowl, mix 2 tbsp olive oil, 3 tbsp lemon juice, 2 tbsp chopped fresh rosemary, 4 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper. Add 4 chicken breasts and coat well. Marinate for at least 30 minutes in the refrigerator.
  2. Step 2: Preheat grill to medium-high heat (about 400°F). Grill the marinated chicken breasts for 6-7 minutes per side, until internal temperature reaches 165°F and juices run clear.
  3. Step 3: While chicken grills, place 2 lbs peeled and quartered potatoes into a large pot of salted water. Bring to a boil and cook for 15-20 minutes until potatoes are tender when pierced with a fork.
  4. Step 4: Drain the potatoes and return to the pot. Add 4 tbsp butter, 1/2 cup whole milk, and mash until smooth and creamy. Season with salt and pepper to taste.
  5. Step 5: Serve the grilled lemon-rosemary chicken breasts alongside generous portions of garlic mashed potatoes.
