Ingredients:

For the Chicken:

- 1 tablespoon olive oil or avocado oil (if cooking raw chicken)
- Salt and freshly ground black pepper, to taste
For the Vegetables:
- 1 tablespoon olive oil or avocado oil
- 1 medium yellow onion, chopped
- 3 cloves garlic, minced
- 1 head broccoli, cut into small florets (about 3-4 cups)
- 1/2 head cauliflower, cut into small florets (about 2-3 cups)
- 1 medium red bell pepper, deseeded and chopped (optional, for color and sweetness)
For the Creamy Sauce:
- 8 ounces cream cheese, softened
- 1 cup heavy cream
- 1/2 cup chicken broth (low sodium preferred)
- 1 teaspoon onion powder
- 1 teaspoon garlic powder
- 1 teaspoon dried Italian herbs
- 1/2 teaspoon smoked paprika (for a lovely depth of flavor!)
- Salt and freshly ground black pepper, to taste
For the Cheese Topping:
- 1.5 cups shredded sharp cheddar cheese, divided
- 1/2 cup grated Parmesan cheese, divided
Optional Garnish:
- Fresh parsley or chives, chopped

Preparation Phase 1: Preparing Your Chicken

Cook the Chicken (if starting with raw): If you’re not using pre-cooked chicken, let’s get this done first. Pat your chicken breasts or thighs dry with paper towels. Season generously with salt and black pepper. In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Once shimmering, add the chicken and cook for 5-7 minutes per side, or until golden brown and cooked through (internal temperature reaches 165°F or 74°C). This pan-searing method not only cooks the chicken but also develops a wonderful depth of flavor. If you prefer, you can also bake your chicken at 375°F (190°C) for 20-25 minutes until cooked through. Using pre-cooked chicken, like a rotisserie chicken, is my favorite shortcut to make this an truly Easy Low Carb Chicken Casserole!
Shred or Dice the Chicken: Once your chicken is cooked, remove it from the skillet and let it rest for 5 minutes. This helps the juices redistribute, ensuring your chicken stays tender and moist. After resting, either shred it using two forks or dice it into bite-sized pieces, about 1/2 to 3/4 inch in size. Set aside.

Preparation Phase 2: Sautéing Your Veggies and Building the Creamy Base

Preheat and Prepare Your Baking Dish: While you’re working on the veggies, go ahead and preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with cooking spray or a little olive oil. This prevents sticking and makes cleanup a breeze.
Sauté the Aromatics: In the same large skillet (or a clean one, if you prefer), heat another 1 tablespoon of olive oil over medium heat. Add the chopped yellow onion and cook, stirring occasionally, until it softens and becomes translucent, about 5-7 minutes. Don’t rush this step, as the softened onions lay a foundational sweetness for our Easy Low Carb Chicken Casserole. Add the minced garlic and cook for an additional 1 minute until fragrant. Be careful not to burn the garlic, as it can turn bitter very quickly.
Add the Vegetables: Now, add your broccoli florets, cauliflower florets, and chopped red bell pepper (if using) to the skillet with the onions and garlic. Sauté for 5-7 minutes, stirring frequently, until the vegetables are slightly tender-crisp. We want them to still have a bit of bite, as they will continue to cook in the oven. Season lightly with salt and pepper at this stage.
Prepare the Creamy Sauce: Reduce the heat to low. Add the softened cream cheese to the skillet with the sautéed vegetables. Use a wooden spoon or spatula to stir and break up the cream cheese as it melts. Once it starts to soften, slowly pour in the heavy cream and chicken broth, whisking constantly to incorporate the cream cheese smoothly into the liquids. Continue whisking until the sauce is smooth and creamy, without any lumps of cream cheese. This is where the magic happens for our rich and flavorful “Easy Low Carb Chicken Casserole” sauce!
Season the Sauce: Stir in the onion powder, garlic powder, dried Italian herbs, and smoked paprika. Taste the sauce and adjust the salt and black pepper as needed. You want the sauce to be well-seasoned, as it’s the primary flavor driver for the entire casserole. Remember that the cheese you add later will also contribute saltiness, so be mindful not to over-salt at this stage. The aroma filling your kitchen at this point is truly wonderful!

Preparation Phase 3: Assembling Your Easy Low Carb Chicken Casserole

Combine Ingredients: Add your cooked and shredded or diced chicken into the skillet with the creamy vegetable sauce. Stir gently until the chicken and vegetables are evenly coated with the rich, aromatic sauce.
Add Some Cheese to the Mix: Stir in 1 cup of the shredded sharp cheddar cheese and 1/4 cup of the grated Parmesan cheese directly into the chicken and vegetable mixture. This ensures a cheesy goodness throughout every bite, not just on top. Give it another good stir to distribute the cheese evenly.
Transfer to Baking Dish: Carefully spoon the entire chicken and vegetable mixture into your prepared 9×13 inch baking dish. Spread it out evenly using the back of your spoon or spatula, ensuring that the ingredients are distributed from corner to corner.
Top with Remaining Cheese: Sprinkle the remaining 1/2 cup of shredded sharp cheddar cheese and 1/4 cup of grated Parmesan cheese evenly over the top of the casserole. This will create a beautiful golden, bubbly crust when baked, adding another layer of texture and flavor to our “Easy Low Carb Chicken Casserole.”

Cooking Your Low Carb Chicken Casserole

Bake to Perfection: Place the baking dish into your preheated 375°F (190°C) oven. Bake for 25-30 minutes, or until the casserole is bubbly around the edges and the cheese on top is melted and golden brown. The exact timing can vary slightly depending on your oven, so keep an eye on it after the 20-minute mark. You want that lovely crust without burning the cheese.
Optional Broiling for Extra Crisp: For an extra golden-brown and slightly crispy cheese topping, you can carefully turn on your broiler for the last 2-3 minutes of cooking. Watch it very closely, as cheese can go from perfectly golden to burnt in a matter of seconds under the broiler.
Rest Before Serving: Once your Easy Low Carb Chicken Casserole is out of the oven, resist the urge to dive in immediately! Let it rest on a wire rack for 5-10 minutes. This resting period allows the sauce to set slightly, making it easier to serve and preventing it from being too runny. It also ensures every bite is perfectly moist and flavorful.

Serving Suggestions and Storage Tips

Garnish and Serve: If desired, sprinkle with fresh chopped parsley or chives for a pop of color and fresh flavor before serving. This casserole is hearty enough to be a complete meal on its own, but it also pairs wonderfully with a simple green side salad dressed with a light vinaigrette, or perhaps some steamed green beans or asparagus. The freshness of a simple salad provides a lovely contrast to the richness of the casserole.
Storage: Leftovers of this Easy Low Carb Chicken Casserole store beautifully! Transfer any cooled leftovers to an airtight container and refrigerate for up to 3-4 days. This makes it an excellent meal prep option for busy weeks.
Reheating: To reheat, you can portion individual servings into a microwave-safe dish and heat until warmed through, usually 1-2 minutes, stirring halfway. For larger portions or to reheat the entire dish, place it back into an oven-safe dish, cover loosely with foil, and bake at 350°F (175°C) for 15-20 minutes, or until heated through. Removing the foil for the last few minutes can help crisp up the topping again.
Freezing (Optional): This casserole also freezes well! Once completely cooled, you can either freeze it whole in the baking dish (if it’s freezer-safe and covered tightly with foil and plastic wrap) or portion it into individual freezer-safe containers. It will keep for up to 2-3 months. Thaw overnight in the refrigerator before reheating. Freezing this casserole makes it an even more convenient option for busy households looking for a quick, low-carb meal.

Unleash Your Culinary Creativity: Serving Suggestions & Variations

While this casserole is undeniably a complete and satisfying meal on its own, I love exploring different ways to serve and personalize it. For a light and refreshing counterpoint, I often pair it with a crisp green salad tossed in a simple vinaigrette, or a side of steamed non-starchy vegetables like broccoli, asparagus, or green beans. These additions not only boost the nutritional value but also add a lovely textural contrast, making each bite even more interesting. A sprinkle of fresh parsley or chives right before serving also adds a pop of color and a fresh, herbaceous note that elevates the entire dish, giving it a gourmet touch without any extra fuss.

But don’t stop there! This recipe is incredibly adaptable, inviting you to put your own spin on it. Feel free to experiment with different cheeses – a sharp cheddar, a smoky gouda, or even a Monterey Jack could add intriguing new dimensions of flavor. If you’re a fan of a little heat, a pinch of red pepper flakes or a dash of hot sauce stirred into the mixture would certainly liven things up. For extra vegetables, consider adding sautéed mushrooms, bell peppers, or even a handful of spinach or kale to the chicken mixture before baking. They wilt down beautifully and blend seamlessly into the creamy sauce, boosting both flavor and nutrition. I’ve even tried adding a touch of Dijon mustard to the sauce for an extra layer of savory depth, which was absolutely delightful!

Thinking beyond the basic, this casserole can be dressed up or down to suit any occasion. For a more robust meal, you could serve it alongside a small portion of cauliflower rice or zucchini noodles, which absorb the delicious sauce wonderfully. If you’re feeding a crowd, you can easily double the recipe and bake it in a larger dish. For those who enjoy a bit of crunch, a topping of crushed pork rinds mixed with melted butter can create a fantastic breadcrumb-like crust that’s entirely low-carb and adds a delightful texture. The possibilities truly are endless, and I encourage you to see this recipe as a canvas for your own culinary masterpieces. It’s robust enough to handle various additions and substitutions while maintaining its comforting core.
