This is a complete, comforting meal where juicy chicken, tender potatoes, and vibrant broccoli roast together on one pan. Everything is coated in a luscious, savory sauce that bakes into a golden, cheesy crust. It's an impressively easy family favorite with maximum flavor and minimal cleanup.
For extra crispiness, broil for the final 2-3 minutes, watching closely. Use freshly grated Parmesan for the best melting sauce. Chicken breasts can be used but reduce cook time by 5-7 minutes. Store leftovers in an airtight container in the fridge for 3-4 days.
