A simple sheet-pan dinner featuring garlic- and herb-marinated chicken roasted with golden baby potatoes and crisp-tender green beans. Ready in about 45 minutes and perfect for busy weeknights.
Preheat oven to 425°F (220°C). Line a rimmed baking sheet with parchment or lightly oil it. Pat chicken dry and set aside.
Whisk together 3 tablespoons olive oil, garlic, lemon zest and juice, rosemary, thyme, parsley, Dijon, salt, pepper, and red pepper flakes. Reserve about 2 tablespoons for the green beans.
Toss potatoes with 1 tablespoon olive oil, salt, and a little chopped herb. Spread on the baking sheet and roast for 15–20 minutes until golden and tender.
Coat chicken in the garlic-herb mixture and add to the sheet pan with the potatoes. Toss green beans with the reserved marinade and add to the pan.
Roast 15–20 more minutes until chicken registers 165°F (74°C) and green beans are blistered. Broil 1–2 minutes if you want extra browning.
Let chicken rest 5 minutes, dot with butter if using, garnish with parsley and a squeeze of lemon, then serve.
Notes
Marinate the chicken up to 24 hours ahead to deepen flavor.
Store leftovers in an airtight container in the refrigerator for up to 3 days.
