Essential Ingredients for Easy Low Carb Chicken Casserole
Chicken Breast: Boneless, skinless chicken breasts are the star here—they provide lean protein that’s essential for a filling meal. I always opt for fresh ones, but rotisserie chicken works in a pinch to save time. In the Easy Low Carb Chicken Casserole, they get shredded and mixed in, absorbing all the flavors beautifully. Cooking them first ensures they’re tender and juicy, not dry.
Broccoli Florets: These add crunch and nutrients without piling on carbs. Steamed lightly, they blend seamlessly into the casserole. What I find interesting is how broccoli’s subtle earthiness complements the cheese, making the whole dish more vibrant. They’re a must for that low carb veggie boost.
Cheddar Cheese: Shredded sharp cheddar brings the creamy, melty magic that defines a great casserole. It melts into a golden top that’s irresistible. For the Easy Low Carb Chicken Casserole, use full-fat for the best texture and flavor—low-fat versions can get watery. It’s what makes this dish feel indulgent yet guilt-free.
How to Make Easy Low Carb Chicken Casserole
Prep the Chicken and Veggies
Start by cooking your chicken breasts in a skillet with a bit of oil until they’re no longer pink inside—this usually takes about 10 minutes. Shred them with two forks right in the pan for that easy Low Carb Chicken Casserole vibe. Meanwhile, steam the broccoli and cauliflower until just tender; you don’t want them mushy. In my experience, this step sets the foundation for a dish that’s packed with texture. Mix in some garlic powder and salt to season everything early on.
Assemble the Casserole Layers
Now, grab a baking dish and layer in the shredded chicken and veggies. Pour over a creamy mixture of heavy cream, sour cream, and half the cheese—it should coat everything nicely. Here’s the thing: stir gently to combine without breaking up the veggies too much. The aromas will start filling your kitchen, making it hard to wait. This is where the Easy Low Carb Chicken Casserole starts to come alive with its comforting scents.
Bake to Golden Perfection
Top with the remaining cheese and bake at 375°F for 25-30 minutes until bubbly and browned. Keep an eye on it—the cheese should be golden, not burnt. Once out of the oven, let it rest for 5 minutes so it sets up. For extra crisp, broil for the last 2 minutes. Your Easy Low Carb Chicken Casserole is ready to serve, hot and delicious.

Ingredients
- 4 boneless, skinless chicken breasts (about 1.5 lbs)
- 2 cups broccoli florets
- 2 cups cauliflower florets
- 1 ½ cups shredded sharp cheddar cheese, divided
- 1 cup heavy cream
- ½ cup sour cream
- 2 cloves garlic, minced
- 1 tsp salt
- ½ tsp black pepper
- 1 tsp garlic powder
- Optional: ½ cup chopped spinach for extra greens
Easy Low Carb Chicken Casserole Instructions
- Preheat your oven to 375°F (190°C). In a large skillet over medium heat, cook the chicken breasts with a drizzle of olive oil for 8-10 minutes per side until fully cooked. Remove from heat, let cool slightly, then shred using two forks.
- While the chicken cooks, steam the broccoli and cauliflower in a pot with a steamer basket for 5-7 minutes until tender-crisp. Drain well to avoid excess moisture in your casserole.
- In a large mixing bowl, combine the shredded chicken, steamed veggies, minced garlic, garlic powder, salt, and pepper. Stir in the heavy cream and sour cream until everything is evenly coated. Fold in half of the shredded cheddar cheese.
- Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle the remaining cheddar cheese on top. Bake for 25-30 minutes, or until the cheese is melted and bubbly with golden edges. For extra crispiness, broil for 1-2 minutes at the end.
- Remove from the oven and let it rest for 5 minutes before serving. This allows the flavors to settle and makes it easier to portion.

Don’t Skip the Rest: After baking, give your Easy Low Carb Chicken Casserole a few minutes to cool—this prevents it from being too soupy when served.

How to Store Easy Low Carb Chicken Casserole
Once cooled, portion your Easy Low Carb Chicken Casserole into airtight containers and refrigerate for up to 4 days. For longer storage, freeze in freezer-safe bags for up to 2 months—thaw overnight in the fridge before reheating. I find reheating in the oven at 350°F for 15-20 minutes works best to restore that crispy top, though the microwave is fine for single servings. Just add a splash of cream if it seems dry.
Customizing Your Easy Low Carb Chicken Casserole
Feel free to swap broccoli for zucchini or add mushrooms for more variety in your Easy Low Carb Chicken Casserole. If you want a spicy kick, mix in some diced jalapeños or a dash of hot sauce. For a dairy-free version, use coconut cream instead of heavy cream—it still gives that richness. Check out this Greek chicken meatballs with lemon orzo recipe for inspiration on herb additions.
What to Serve with Easy Low Carb Chicken Casserole
This dish pairs wonderfully with a crisp green salad to keep things light—try a simple cucumber salad for contrast. For a heartier meal, add roasted Brussels sprouts or zucchini fries on the side. If you’re in the mood for something refreshing, a tangy vinaigrette-dressed salad works great. Don’t forget a glass of sparkling water with lemon to complement the creamy flavors.
