Instructions
Start by preheating your oven to 400°F. Lightly grease a baking dish with olive oil or nonstick cooking spray so nothing sticks later.
Pat the chicken breasts dry with paper towels. This helps the seasoning cling better and gives the chicken a nicer texture as it bakes.
Rub the chicken with olive oil, paprika, onion powder, garlic powder, salt, black pepper, and lemon juice. Make sure each piece is coated well. The lemon gives the chicken a small fresh lift that balances the richness of the cheese.
Place the seasoned chicken breasts in the prepared baking dish.
Now scatter the broccoli florets around the chicken. Drizzle them lightly with olive oil, then sprinkle with a little salt, pepper, minced garlic, and chili flakes if you want a gentle kick of heat.
In a bowl, mix the mayonnaise or Greek yogurt with the sour cream, cheddar cheese, mozzarella cheese, and Parmesan. Stir until everything is creamy, thick, and well combined.
Spoon the cheesy mixture over the top of each chicken breast. Be generous here. The topping will melt into a bubbly, golden layer as it bakes.
Place the dish in the oven and bake for 25 to 30 minutes, or until the chicken is fully cooked and reaches an internal temperature of 165°F.
For a beautiful golden top, switch the oven to broil for the last 2 to 3 minutes. Keep a close eye on it, because cheese can go from perfectly bubbly to too dark very quickly.
Once it’s done, let the casserole rest for about 5 minutes before serving. This gives the juices time to settle and makes the chicken even better.
Presentation
Serve each chicken breast with a generous spoonful of broccoli on the side, making sure to scoop up some of the melted cheese from the baking dish.
For a pretty finish, sprinkle a little extra Parmesan over the top while everything is still warm. A pinch of fresh parsley also adds a nice pop of color if you have it.
This casserole looks especially inviting in a rustic baking dish brought straight to the table. For a heartier plate, serve it over fluffy rice, creamy mashed potatoes, or buttered pasta so the cheesy sauce has something cozy to sink into.
