Ingredients You’ll Need
You’ll be amazed by how much flavor these everyday ingredients bring to your Easy Low Carb Chicken Casserole. Each ingredient plays an essential role—bringing everything from creamy texture to vibrant pops of color and satisfying protein. Here’s what you’ll need, and a quick tip for each one:
- Cooked chicken (3 cups, shredded): Rotisserie or leftover roast chicken works perfectly for both flavor and convenience.
- Cauliflower rice (2 cups): This sneaky veggie base lends a tender bite and keeps things light while soaking up every bit of the sauce.
- Shredded cheddar cheese (1 cup): Sharp cheddar gets melty and gooey, tying all the flavors together with classic coziness.
- Sour cream (½ cup): This adds a lovely tang and keeps the casserole wonderfully moist.
- Cream cheese, softened (½ cup): For the silkiest sauce, make sure your cream cheese is at room temp so it blends perfectly.
- Broccoli florets, steamed and chopped (1 cup): Broccoli brings vibrant green color, subtle crunch, and a healthy dose of veggies.
- Small onion, finely chopped (1): Onion gives gentle sweetness and depth, making every bite more interesting.
- Garlic, minced (2 cloves): Don’t skip garlic! It adds tremendous aroma and irresistible flavor.
- Dried Italian seasoning (1 teaspoon): A quick way to layer in subtle herby notes—use homemade or store-bought.
- Salt (½ teaspoon): Just enough to bring all the ingredients together harmoniously.
- Black pepper (¼ teaspoon): For a hint of warmth and depth without being spicy.
- Grated Parmesan cheese (¼ cup): Sprinkled on top, it gets golden and crisp in the oven—the perfect casserole crown!
How to Make Easy Low Carb Chicken Casserole
Step 1: Preheat and Prep Your Pan
Start by preheating your oven to 375°F, so it’s good and hot by the time your casserole is assembled. Lightly grease a 9×9-inch baking dish—for easiest cleanup, you can use nonstick spray or a thin coat of butter. A warm oven and a ready dish guarantee that bubbly, golden finish we all love.
Step 2: Mix the Main Ingredients
In your biggest mixing bowl, toss in the shredded chicken, cauliflower rice, cheddar cheese, sour cream, softened cream cheese, broccoli, onion, garlic, dried Italian seasoning, salt, and pepper. Using a sturdy spoon or spatula, mix everything thoroughly until the sauce coats each and every morsel. Taking a few extra seconds to mix well ensures the Easy Low Carb Chicken Casserole bakes up perfectly even and rich.
Step 3: Transfer and Top
Spoon your mixture into the prepared baking dish, spreading it out evenly. Pat it down gently to fill the corners and smooth the top—a flat surface helps the Parmesan topping brown just right. Sprinkle the grated Parmesan generously over everything, which will turn into a crisp, golden layer during baking.
Step 4: Bake to Perfection
Slide the dish into your preheated oven and bake for 25 to 30 minutes. You’ll know it’s ready when the casserole is hot and bubbly all the way through, and the top is lightly golden and crisped. If you like a little extra golden-brown crunch, broil for an additional 1 to 2 minutes at the end, watching carefully so it doesn’t burn.
Step 5: Cool and Serve
Remove your Easy Low Carb Chicken Casserole from the oven and let it rest for at least 5 minutes. This makes slicing neater (plus, it saves palates from molten cheese burns). Now you’re ready to scoop, garnish, and savor!
How to Serve Easy Low Carb Chicken Casserole

Garnishes
A handful of fresh herbs always adds life and color—think chopped parsley, fresh basil, or even a sprinkle of chives. You can also add extra grated Parmesan or a few red pepper flakes if you crave a subtle kick. Not only do garnishes look beautiful, but they also add a pop of freshness to this savory classic.
Side Dishes
This casserole shines alongside a bright, simple salad (like arugula tossed with lemon vinaigrette) or sautéed green beans for extra crunch. If you’re not counting carbs as strictly, a slice of crusty bread or a scoop of mashed cauliflower is fabulous for soaking up the creamy sauce. Pick sides that offer a bit of contrast—color, crunch, or tang—to round out the meal.
Creative Ways to Present
For a fun twist, serve individual portions in ramekins for everyone at the table—a dinner party hit! Or, pile the casserole filling into hollowed-out bell peppers before baking for a playful, veggie-packed variation. You can even use the filling inside baked zucchini boats for fancy weeknight flair. Presentation transforms this Easy Low Carb Chicken Casserole into a customizable canvas for your creativity.
Make Ahead and Storage
Storing Leftovers
Leftover Easy Low Carb Chicken Casserole is one of life’s little joys. Let the casserole cool to room temperature, then store in an airtight container in the refrigerator for up to four days. The flavors seem to meld and improve over time, making your next lunch or dinner even better.
Freezing
This dish loves your freezer! Once baked and cooled, transfer portions to freezer-safe containers or wrap the baking dish tightly in plastic wrap and foil. Label with the date—your future self will thank you! The casserole keeps well in the freezer for up to three months. To thaw, let it sit overnight in the fridge before reheating.
Reheating
To reheat, warm your Easy Low Carb Chicken Casserole in a 350°F oven, covered with foil, until heated through (about 20–25 minutes for a whole casserole or 5–10 minutes for smaller portions). If you’re in a hurry, a microwave works too—just use a microwave-safe dish and cover loosely to prevent drying out. Add a sprinkle of fresh cheese before reheating for a just-baked finish.
FAQs
Can I use rotisserie chicken for this recipe?
Absolutely! Rotisserie chicken is a major time-saver and packs in lots of savory flavor. Just shred or chop the meat and toss it straight into your Easy Low Carb Chicken Casserole mixture.
What can I use instead of cauliflower rice?
If cauliflower isn’t your thing or you want to switch it up, try broccoli rice, chopped spinach, or even finely chopped zucchini. Each option keeps it low carb and interesting, so feel free to play with different veggie bases.
How can I make this recipe dairy-free?
For a dairy-free version, swap the cream cheese, sour cream, cheddar, and Parmesan for your favorite plant-based alternatives. You’ll still get that luscious, rich texture while keeping the casserole allergy-friendly.
Is it possible to prepare Easy Low Carb Chicken Casserole ahead of time?
Yes! You can assemble the casserole up to a day ahead, cover it, and store it in the refrigerator. When ready to bake, let it sit at room temperature for 10–15 minutes and then follow the baking instructions. Dinner will be ready with minimal effort!
Can I add more veggies to this casserole?
Definitely. Feel free to stir in extra veggies like chopped bell peppers, mushrooms, spinach, or asparagus. Just make sure they’re cooked or lightly steamed so they blend seamlessly with the rest of the ingredients.
