How to make broccoli cheddar biscuit casserole
Step-by-Step Cooking Method
- Preheat oven to 375°F and lightly butter a 13×9-inch baking dish. Set aside.
- Sauté the base: In a large skillet over medium heat, melt butter. Add diced onion and cook for 8 minutes until soft. Stir in garlic and cook for 1 more minute.
- Make the sauce: Sprinkle in the flour and whisk for 1 minute. Slowly add chicken broth and milk while whisking to prevent lumps. Stir until smooth and slightly thickened.
- Add broccoli and season: Stir in broccoli florets, salt, pepper, and cayenne. Simmer uncovered for 12–15 minutes, stirring occasionally, until broccoli is tender.
- Add chicken and cheese: Stir in shredded rotisserie chicken and cheddar cheese. Stir until the cheese is fully melted and the filling is creamy and cohesive.
- Transfer to baking dish: Pour the mixture into the prepared baking dish. Arrange 6 biscuits evenly across the top.
- Bake: Place in the oven and bake for 15 minutes or until the biscuits are golden brown and cooked through, and the casserole is bubbling around the edges.
- Garlic butter finish: While it bakes, combine melted butter, minced garlic, parsley, and salt in a small bowl. As soon as it comes out of the oven, brush the tops of the biscuits generously with the garlic butter mixture.
- Cool and serve: Let cool for 5 minutes before serving to allow everything to set.

Storage Instructions

Frequently Asked Questions
Can I make this ahead of time?
Yes. Assemble the filling and store it in the baking dish (without biscuits) covered in the fridge for up to 24 hours. When ready to bake, top with biscuits and continue as directed.
Can I freeze it?
It’s best freshly baked, but you can freeze leftovers. Let cool completely, wrap tightly, and freeze for up to 2 months. Reheat in the oven until hot throughout.
What kind of cheese works best?
Freshly grated cheddar cheese is classic for that rich, sharp flavor. You can mix in other options like Monterey Jack or gouda for a creamier texture.
Can I use homemade biscuits?
Absolutely. Just make sure they’re not too thick so they bake through in the same time frame.
How do I know the biscuits are done?
They should be puffed and golden brown on top and cooked through on the underside. If unsure, gently lift one biscuit to check that the bottom is not doughy.
