Preheat the oven to 425°F and line a large, rimmed baking sheet with parchment paper.
Prepare and chop the potatoes, onion, carrots, and green beans, then toss them together directly on the baking sheet.
10-12 ounces baby potatoes, 1 medium red onion, 6-8 medium whole carrots, 6-8 ounces green beans
Sprinkle the garlic and 2 teaspoons of the Herbes de Provence on top, then drizzle very lightly with olive oil. Mix briefly with tongs or your hands to evenly coat the veggies.
3-4 garlic cloves, 4 teaspoons Herbes de Provence, olive oil
Place the chicken thighs on top of the veggies. Brush the skin very lightly with olive oil, then sprinkle with the remaining 2 teaspoons Herbes de Provence. Sprinkle both the chicken and veggies generously with kosher salt and black pepper.
1 and 1/2 pounds chicken thighs, kosher salt and black pepper
Place in the oven and roast for 40-45 minutes, stirring the veggies once as they roast. (If your chicken thighs are on the large side, or if your oven temperature is slightly low, the chicken may take longer to cook.) Remove when the chicken is cooked through to 165°F and the potatoes are fork-tender. Enjoy!
