Instructions

Step 1: Preheat oven to 425°F (220°C). Rub chicken thighs with 1 tbsp olive oil, then season with 1/2 tsp salt, 1/2 tsp black pepper, 1 tbsp thyme, and 1 tbsp rosemary. Place on a baking sheet and roast for 35-40 minutes until skin is golden and juices run clear.
Step 2: While chicken roasts, boil potatoes in salted water until tender, about 15-20 minutes. Drain and return to pot.
Step 3: In the same pot, melt 2 tbsp butter over medium heat. Add 1/2 cup milk, 1/2 tsp salt, 1/2 tsp black pepper, and 2 minced garlic cloves. Stir until creamy and smooth, then mix in cooked potatoes.
Step 4: In a separate bowl, whisk remaining 1 tbsp olive oil, 1 tbsp lemon juice, and 1 tbsp lemon zest. Toss with garlic mashed potatoes before serving alongside roasted chicken.
