Instructions
- Step 1: Preheat oven to 425°F. In a bowl, combine 3 tbsp olive oil, 1 tbsp chopped fresh rosemary, 4 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper. Toss 4 bone-in chicken thighs in this mixture until evenly coated.
- Step 2: Arrange the chicken thighs skin-side up on a baking sheet lined with foil. Roast in the oven for 35-40 minutes until the skin is golden and juices run clear.
- Step 3: Meanwhile, place 2 peeled and cubed large sweet potatoes in a pot and cover with cold water. Bring to a boil over high heat, then reduce to medium and simmer for 15 minutes until tender.
- Step 4: Drain the sweet potatoes and return them to the pot. Add 2 tbsp unsalted butter, 1/4 cup whole milk, and 1/4 tsp ground cinnamon. Mash with a potato masher until smooth and creamy.
- Step 5: Serve the roasted chicken thighs on a plate alongside a generous scoop of sweet potato mash for a hearty and fragrant dinner.
