This broccoli cheddar biscuit casserole became my answer when I wanted all the comfort of chicken and dumplings but with way more flavor and those amazing fluffy biscuits on top. The creamy, cheesy base loaded with tender broccoli and rotisserie chicken gets topped with golden biscuits and finished with garlic butter that makes the whole thing absolutely irresistible. I came up with this recipe when I was craving something hearty and comforting but wanted it to feel a little more special than regular weeknight casseroles.
My mother-in-law, who's pretty critical about casseroles and usually just picks at them, went back for seconds of this and asked for the recipe before she left. She said it reminded her of the best parts of chicken pot pie but way easier to make and serve. Now she makes it for her church potlucks and everyone raves about it.
What Makes It Special
- Homemade cream sauce: Way better than canned soup and you control the flavor
- Fresh broccoli florets: Cook just until tender so they don't get mushy
- Sharp cheddar cheese: Adds that perfect tangy richness throughout
- Rotisserie chicken: Already seasoned and adds depth to the whole casserole
- Fluffy biscuits: Top everything with golden, buttery perfection
- Garlic butter finish: Takes those biscuits from good to absolutely amazing

Making It Happen
- Creating the base:
- Preheat your oven to 375°F and butter a 9x13 baking dish. In a large skillet, melt butter over medium heat and cook your diced onion until it's translucent, about 8 minutes. Add the minced garlic and cook for another minute until it smells amazing.
- Building the sauce:
- Sprinkle flour over the onion mixture and whisk until lightly browned, about a minute. Slowly pour in chicken broth and milk while whisking constantly to prevent lumps. This creates your cream sauce base that holds everything together.
- Adding the vegetables:
- Add the broccoli florets, salt, pepper, and cayenne to the sauce. Bring everything to a simmer and cook uncovered for 12-15 minutes, stirring occasionally, until the broccoli is tender but not mushy.
- Finishing the filling:
- Stir in the shredded rotisserie chicken and sharp cheddar cheese, mixing until the cheese is completely melted and everything's well combined. Remove from heat and transfer to your prepared baking dish.
- Topping with biscuits:
- Take 6 biscuits from your can and arrange them on top of the casserole mixture. Bake for 15 minutes until the biscuits are golden brown and cooked through.
- The garlic butter magic:
- While the casserole bakes, mix melted butter with salt, minced garlic, and fresh parsley. As soon as the casserole comes out of the oven, brush this garlic butter over the tops of the biscuits for that incredible finishing touch.
I learned that getting the sauce consistency right is crucial. My first attempt was too thin because I rushed the flour cooking step, but taking time to let it brown properly creates a much richer, thicker sauce that holds everything together perfectly.
Perfect Serving Ideas
This casserole is hearty enough to be a complete meal, but it's great with a simple green salad or some fresh fruit to balance out all that richness. The creamy, cheesy flavors pair really well with something light and fresh. For drinks, iced tea or a crisp white wine complement the flavors perfectly.
Making It Different
You can customize this easily by using different vegetables like cauliflower or carrots instead of broccoli. Sometimes I add mushrooms for extra flavor, or use different cheeses like Gruyere for a more sophisticated taste. Turkey instead of chicken works great too, especially around the holidays.
Storage and Reheating
This casserole keeps beautifully in the refrigerator for several days and reheats well in the oven to restore the biscuit texture. Cover with foil to prevent the tops from getting too brown during reheating. It also freezes well before baking, just thaw overnight and bake as directed.
