This one-skillet citrusy lemon, fragrant rosemary, and flavorful garlic chicken and potato dish is fancy enough for sit-down Sunday night table dining and easy enough for a busy weeknight eat-at-the-counter dinner. The trifecta of flavors infuses the chicken under the skin and in the bright lemony, herby sauce. The chicken and potatoes are browned on the stove and roasted in the oven in the same pan, which means quick clean-up!
