Can I use frozen broccoli instead of fresh?

Yes, frozen broccoli can be used but should be thawed and well drained before mixing to avoid excess moisture in the bake.

What cheese works best for this dish?

Sharp cheddar cheese is ideal for a rich, tangy flavor that melts smoothly into the sauce and crisps well on top.

Blanch or steam broccoli just until tender-crisp to preserve its vibrant color and texture before combining it with the sauce.

Yes, assemble the bake ahead and refrigerate. Bake just before serving to maintain the crisp topping and creamy sauce.

A comforting, creamy casserole featuring tender chicken, fresh broccoli, and a golden cheddar cheese topping—perfect for a family dinner or potluck.

I made this casserole after a busy weekday and it quickly became our family's favorite for its simplicity and heartiness.

Prepare the oven:: Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch (23x33 cm) baking dish.
Blanch the broccoli:: Steam or blanch the broccoli florets in boiling water for 2 3 minutes until just tender and bright green. Drain and set aside.
Make the sauce base:: In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1 minute, whisking constantly.
Thicken the sauce:: Gradually add the milk and chicken broth, whisking to prevent lumps. Cook for 3 4 minutes until the sauce thickens.
Add seasonings:: Stir in Dijon mustard, garlic powder, onion powder, salt, and black pepper. Remove from heat.
Incorporate cheese:: Add 1 cup of cheddar cheese to the sauce and stir until melted and smooth.
Combine ingredients:: In a large bowl, combine the cooked chicken, blanched broccoli, and cheese sauce. Mix well.
Assemble casserole:: Spread the mixture evenly in the prepared baking dish.
Add topping:: Sprinkle the remaining 1/2 cup cheddar cheese over the top.
Finish topping:: In a small bowl, toss panko breadcrumbs with olive oil (and red pepper flakes, if using), then sprinkle over the casserole.
Bake:: Bake for 25 30 minutes until bubbling and the top is golden brown.
Rest and serve:: Let cool for 5 minutes before serving.

This dish always reminds me of Sunday family gatherings when everyone arrived hungry and left with smiles after a hearty meal.
