Instructions

  1. Step 1: Combine 3 tbsp fresh lemon juice, 2 tbsp chopped fresh thyme leaves, 2 tbsp olive oil, 3 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper in a bowl. Add 4 boneless skinless chicken breasts and marinate for 30 minutes at room temperature.
  2. Step 2: Meanwhile, place 1.5 lbs small Yukon gold potatoes in a large pot and cover with cold water. Add 1 tsp salt and bring to a boil over high heat. Cook for 15-18 minutes until the potatoes are fork-tender.
  3. Step 3: Preheat a grill or grill pan to medium-high heat (about 400°F). Remove chicken from marinade and grill for 6-7 minutes per side, until internal temperature reaches 165°F and chicken is nicely charred.
  4. Step 4: Drain potatoes and place them on a baking sheet. Using the bottom of a glass or a potato masher, gently smash each potato to about 1/2 inch thickness. Drizzle with 2 tbsp olive oil, 3 tbsp unsalted butter, remaining 2 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper.
  5. Step 5: Roast smashed potatoes in a preheated 425°F oven for 20-25 minutes until golden and crispy on edges. Serve grilled chicken with the garlic smashed potatoes immediately.
