This easy low carb rotisserie chicken and broccoli bake is a gluten free, cheesy, one-dish dinner ready in under 40 minutes. A weeknight staple the whole family will love.

Some weeknight dinners feel like a reward. This low carb rotisserie chicken and broccoli bake is exactly that. It is warm, cheesy, deeply satisfying, and shockingly simple to pull together. We are talking about a real, hearty gluten free chicken bake that lands on the table in under 40 minutes, using a store bought rotisserie chicken as the shortcut that makes it all possible.
Whether you are eating keto, gluten free, or just trying to sneak more vegetables into your week, this casserole delivers. It is the kind of recipe that earns a permanent spot in your dinner rotation.
Let's be honest. The rotisserie chicken does a lot of the heavy lifting. It is already seasoned, already cooked, and already falling-apart tender. All you have to do is shred it. That means less prep time, more flavor, and a casserole that tastes like it took far more effort than it did.
This is also what makes the recipe such a brilliant gluten free chicken and broccoli weeknight fix. No marinating, no pan searing. Just shred, mix, and bake.
Chef's Tip: Look for a plain or lemon herb rotisserie chicken. Heavily seasoned flavors like BBQ or buffalo can clash with the creamy sauce. Check the label to confirm no gluten containing additives are used if you are strictly gluten free.
The creamy base here is a simple blend of softened cream cheese, sour cream, and a splash of chicken broth. It is rich without being heavy, and it clings to every piece of chicken and broccoli beautifully. A generous handful of sharp cheddar gets stirred right in, plus another layer melted over the top for that irresistible golden finish.
This is what separates a great gluten free chicken broccoli casserole from a forgettable one. The sauce has body, has flavor, and holds together without any flour or starch thickener. That means it is naturally low carb and naturally gluten free.
For anyone following a strict gluten free diet, having quality, reliable kitchen tools and certified gluten free ingredients really does make a difference in the outcome of a dish like this.
A few small details go a long way in this recipe.
This easy gluten free chicken casserole approach is also highly flexible. You can swap in cauliflower for part of the broccoli, add a handful of sauteed mushrooms, or stir in some diced green chiles for a mild kick.
Make It Ahead: Assemble the whole casserole, cover tightly, and refrigerate up to 24 hours before baking. Add 5 to 8 extra minutes to the cook time if baking straight from cold.
One of the things people love most about this dish is that it genuinely pleases everyone at the table. Kids love the cheesy, comforting flavor. Adults appreciate that it is a legitimate broccoli chicken bake healthy enough to feel good about. And anyone eating low carb or gluten free can dig in without a second thought.
Each serving comes in at around 390 calories with 38 grams of protein and only 9 grams of carbohydrates. It is filling, nourishing, and built around real whole food ingredients.

This easy low carb rotisserie chicken and broccoli bake is a gluten free, cheesy, one-dish dinner ready in under 40 minutes. A weeknight staple the whole family will love.
Preheat your oven to 400 degrees F (200 degrees C). Lightly grease a 9x13-inch baking dish with olive oil or nonstick spray.
If using fresh broccoli, blanch the florets in boiling salted water for 2 minutes, then drain well and pat dry. If using frozen, make sure it is fully thawed and squeezed of excess moisture.
In a large mixing bowl, beat the softened cream cheese until smooth. Stir in the sour cream, chicken broth, minced garlic, onion powder, garlic powder, smoked paprika, salt, and pepper until fully combined.
Fold in the shredded rotisserie chicken and broccoli florets, coating everything evenly in the creamy sauce.
Stir in 1 cup of the shredded cheddar cheese into the mixture, reserving the remaining half cup for the topping.
Transfer the mixture into the prepared baking dish and spread it into an even layer.
Sprinkle the reserved cheddar cheese evenly over the top.
Bake uncovered for 22 to 25 minutes, until the edges are bubbling and the cheese on top is melted and lightly golden.
Remove from the oven and let rest for 5 minutes before serving.
Serve this easy gluten free chicken casserole straight from the baking dish. It is rustic and casual by design. A sprinkle of fresh parsley or a pinch of red pepper flakes on top adds a nice finishing touch.
Leftovers reheat beautifully. Store them in an airtight container in the refrigerator for up to 4 days. For the best texture, reheat in the oven at 350 degrees F covered with foil, or use the microwave in short bursts. The cream cheese based sauce can separate slightly if overheated, so gentle and low is the way to go.
This is one of those gluten free chicken and broccoli recipes that actually gets better the next day as the flavors meld together. Make a big batch on Sunday and thank yourself on Wednesday.
