This easy low carb rotisserie chicken and broccoli bake transforms a store-bought rotisserie chicken into a creamy, gluten free chicken broccoli casserole the whole family will love in under 40 minutes.

Some weeknight dinners just have a way of becoming instant household staples. This low carb rotisserie chicken bake is one of them. It comes together in about 35 minutes, uses a store-bought rotisserie chicken to cut prep time dramatically, and delivers the kind of creamy, cheesy, satisfying comfort food that nobody ever complains about.
If you have been searching for gluten free chicken and broccoli recipes that actually taste indulgent rather than like a compromise, this is your answer. No condensed soup cans. No flour-based roux. Just wholesome, real ingredients pulled into a bubbly, golden casserole that happens to be naturally low carb and 100% gluten free.
The secret here is the base: softened cream cheese loosened with a splash of chicken broth and rounded out with sour cream. It creates a sauce that is rich without being heavy, and it clings beautifully to every piece of chicken and broccoli. A good hit of smoked paprika and fresh garlic keeps things from feeling flat.
Using a rotisserie chicken is genuinely one of the best decisions you can make on a busy evening. The meat is already seasoned, already cooked, and already perfectly tender. All you are doing is building around it.
Chef's Tip: Pull your rotisserie chicken while it is still warm. The meat shreds far more easily than it does cold from the fridge, and it absorbs the creamy sauce even better.
For a dish like this gluten free chicken bake, a good 9x13-inch ceramic or glass baking dish is worth having on hand. It distributes heat evenly and gives you those gorgeous golden cheese edges. A certified gluten free chicken broth is also essential if you are cooking for anyone with celiac disease or a serious gluten sensitivity.
This is where most broccoli chicken bake recipes go wrong. Raw broccoli dumped straight into a casserole can come out either crunchy and underdone or, if the dish bakes too long, completely waterlogged and sad.
The fix is a 2-minute blanch. Drop your broccoli florets into boiling salted water, count to two minutes, then drain and dry them well. This softens them just enough so they finish perfectly in the oven without turning to mush or releasing a pool of water into your sauce.
A few more tips for the best results:
One of the things people love most about easy gluten free chicken casseroles is how little active effort they require. This one is no different. You make the sauce in one bowl, fold everything together, pour it into a dish, and the oven handles the rest.
It is also endlessly flexible. Swap the cheddar for pepper jack if you want a little heat. Tuck in some cauliflower alongside the broccoli for extra variety. Add a pinch of red pepper flakes to the sauce if your crowd likes bold flavor. The creamy base is forgiving and plays well with most additions.
Storage Note: This gluten free chicken broccoli casserole reheats beautifully. Make a full batch on Sunday and you have easy, satisfying lunches or dinners ready for the next few days.
Ready to pull it all together? Here is the complete step-by-step recipe:

This easy low carb rotisserie chicken and broccoli bake transforms a store-bought rotisserie chicken into a creamy, gluten free chicken broccoli casserole the whole family will love in under 40 minutes.
Preheat your oven to 400 degrees F (200 degrees C). Lightly grease a 9x13-inch baking dish with olive oil and set aside.
Bring a large pot of salted water to a boil. Blanch the broccoli florets for 2 minutes, then drain immediately and pat dry with paper towels. This keeps them tender-crisp rather than mushy in the final bake.
In a large mixing bowl, combine the softened cream cheese, sour cream, and chicken broth. Stir vigorously until smooth and lump-free.
Add the minced garlic, onion powder, smoked paprika, salt, and black pepper to the cream cheese mixture. Stir until fully combined.
Fold in the shredded rotisserie chicken and blanched broccoli florets until everything is evenly coated in the creamy sauce.
Transfer the mixture to the prepared baking dish and spread it out in an even layer.
Sprinkle 1 cup of the shredded cheddar cheese evenly over the top, reserving the remaining 0.5 cup.
Bake uncovered for 20 minutes, then remove from the oven and sprinkle the remaining cheddar on top.
Return to the oven and bake for an additional 5 minutes, or until the cheese is fully melted, bubbly, and beginning to turn golden at the edges.
Remove from the oven and let the casserole rest for 5 minutes before serving.
This bake is satisfying enough to stand completely on its own, especially if you are keeping things low carb. But if you want to round out the meal, a simple green salad or roasted asparagus alongside it is a perfect pairing.
For anyone not following a low carb diet, a scoop of fluffy white rice or some crusty gluten free bread for soaking up the extra sauce turns this into a genuinely hearty dinner.
