- 3 tablespoons unsalted butter

Instructions
This Chicken Broccoli Casserole is a straightforward, comforting meal where tender chicken and broccoli meet a creamy, cheesy sauce topped with a golden, crunchy panko crust. It comes together with easy steps, making dinner feel like a warm hug from Nonna herself.
- Preheat your oven: Set it to 375°F (190°C) so it’s ready to give your casserole that perfect golden finish.
- Prepare the chicken: Season your chicken chunks with salt, black pepper, garlic powder, and onion powder to taste, then sauté them in a pan over medium heat until lightly browned and cooked through, about 6-8 minutes. Set aside.
- Steam the broccoli: Cook your broccoli florets until just tender—bright green and slightly crisp—about 4-5 minutes. Drain well and set aside.
- Make the roux: In the same pan, melt the butter over medium heat, then whisk in the flour until smooth and bubbly, cooking for about 2 minutes to take away the raw flour taste.
- Whisk in milk: Slowly add the whole milk, stirring constantly until the sauce thickens, about 5-7 minutes. Keep it smooth and creamy—no lumps here!
- Add the cheeses: Stir in the shredded mozzarella and grated Parmesan cheese until melted and combined, then season with a pinch of salt and pepper to taste.
- Combine the ingredients: Gently fold the cooked chicken and broccoli into the cheesy sauce until everything is well coated and happy together.
- Transfer to baking dish: Pour the mixture into a greased casserole dish and spread evenly.
- Top with panko breadcrumbs: Sprinkle the panko evenly over the casserole, dot with a few small bits of butter if you like for extra crispiness.
- Bake until bubbly and golden: Place the dish in your preheated oven and bake for about 20-25 minutes, until the top is golden brown and the sauce is bubbling around the edges.
- Garnish with parsley: When it’s out of the oven, scatter fresh chopped parsley over the casserole for a bright, fresh finish.
- Rest and serve: Let the casserole sit for 5 minutes before serving; it helps all those flavors settle perfectly on your plate.
How to Store Chicken Broccoli Casserole
This casserole keeps nicely in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy the leftovers, reheat it gently in the oven or microwave until warmed through. If you want to freeze it, do so before baking—wrap it well and freeze for up to 2 months. Thaw overnight in the fridge before baking as usual.
Tweaks and Additions
This classic Chicken Broccoli Casserole is already full of cozy, comforting flavors, but you can make it even more inviting and tasty with a few simple twists and extras. Here are some easy ways to bring in a little more warmth, zing, and freshness without fussing too much in the kitchen.
- Add a pinch of nutmeg to the sauce: A tiny sprinkle of nutmeg in the creamy sauce adds a lovely depth and subtle warmth that’s classic in many Italian white sauces—just a pinch, don’t go overboard.
- Swap half the broccoli for cauliflower: Mixing in cauliflower florets with the broccoli adds a different texture and a sweeter note, making the casserole even more comforting.
- Stir in roasted garlic: Instead of plain garlic powder, roast a few garlic cloves and mash them into the sauce to give it a mellow, sweet garlic flavor—Nonna approved.
- Use a mix of cheeses: Try blending mozzarella, Parmesan, and a little fontina or provolone for an extra cheesy, melty bite with more character.
- Sprinkle fresh thyme or oregano into the sauce: Toss in some fresh thyme or oregano leaves to the sauce while it’s cooking to bring a subtle herbal brightness that pairs beautifully with the chicken and broccoli.
- Top the casserole with crushed toasted almonds or pine nuts: Swap some or all of the panko for nuts for a lovely crunchy texture and a nutty flavor that’s a bit different but just as delicious.
- Mix in sun-dried tomatoes: Dice some sun-dried tomatoes and fold them into the casserole for a pop of color and a tangy-sweet twist that balances the creaminess nicely.
- Finish with a drizzle of good quality extra virgin olive oil: Once the casserole is out of the oven and resting, drizzle a little olive oil over the top for a fruity, silky finish that brings everything together just so.
