Instructions

1. Step 1: Place 2 peeled and chopped large Yukon Gold potatoes and 4 peeled garlic cloves in a large pot. Cover with cold water and bring to a boil over high heat. Reduce to medium and simmer for 15-18 minutes until potatoes are tender when pierced with a fork.
2. Step 2: While potatoes cook, pat 2 boneless skinless chicken breasts dry. Rub each with 1 tsp salt, 1/2 tsp black pepper, 1 tsp lemon zest, and 1 tbsp finely chopped fresh rosemary.
3. Step 3: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add the chicken breasts and cook for 5-6 minutes per side until golden brown and the internal temperature reaches 165°F.
4. Step 4: Drain the potatoes and garlic, return them to the pot. Add 3 tbsp unsalted butter and 1/2 cup whole milk. Mash with a potato masher until smooth and creamy.
5. Step 5: Plate the chicken breasts atop a bed of garlic mashed potatoes and garnish with 2 tbsp chopped parsley.
