Gather all your ingredients. You will need a medium to large-sized roasting pan. Preheat your oven to 400 degrees.
Quarter the potatoes. If they are larger, you may want to cut them even smaller. Cut the bacon into lardons (small strips about a quarter-inch thick).
Everything Into the Roasting Pan
Add the chicken thighs, bottom side up to the roasting pan. Drizzle each thigh with sunflower oil and then sprinkle each thigh well with kosher salt, black pepper, garlic powder, onion powder, and paprika. Flip the thighs (skin side up now), drizzle with sunflower oil, and season the same way you seasoned the other side. Move the thighs to one side of the roasting pan.
Add the green beans, potatoes, and bacon to the other side of the roasting pan. Drizzle with sunflower oil and season with kosher salt and pepper. Mix to combine and spread out in one layer.
Place the roasting pan in a 400-degree oven and bake for about 30 minutes, or until the chicken juices run clear.
Let the chicken rest for about five minutes after removing from the oven, serve, and enjoy!
