  • 2 cloves garlic minced
For the Cream Sauce
  • 8 oz cream cheese full-fat, softened and cut into cubes
  • 1 cup chicken broth low sodium
  • 1/2 cup heavy cream
  • 1 tbsp Dijon mustard
  • 1/2 tsp Xanthan gum optional, for thickening, or use 1 tbsp cream cheese
  • 1 cup sharp cheddar cheese shredded, divided
  • 1/2 cup Parmesan cheese grated

For Garnish
  • 2 tbsp fresh parsley chopped

Equipment

  • Large Skillet or Dutch Oven
  • 9×13 inch baking dish
  • Mixing bowl
  • Whisk

Method
 

Prepare Chicken
  1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish and set aside.
  2. Pat diced chicken dry with paper towels. In a mixing bowl, toss chicken with olive oil, 1/2 tsp salt, 1/4 tsp black pepper, and 1/2 tsp garlic powder.
  3. Heat a large skillet or Dutch oven over medium-high heat. Add the seasoned chicken and cook for 5-7 minutes, stirring occasionally, until browned on all sides and mostly cooked through. Remove chicken from skillet and set aside.
Sauté Vegetables
  1. In the same skillet (no need to clean), add diced onion and cook for 3-4 minutes until softened. Add minced garlic and cook for another minute until fragrant.
  2. Stir in the broccoli florets. If using fresh, cook for 3-5 minutes until tender-crisp. If using frozen, cook for 5-7 minutes until heated through and slightly softened. Remove vegetables from the skillet and set aside with the chicken.
Make the Creamy Sauce
  1. Reduce heat to medium-low. Add the cubed softened cream cheese to the skillet and stir until mostly melted. Gradually whisk in the chicken broth and heavy cream until the sauce is smooth. Stir in the Dijon mustard.
  2. If using, sprinkle Xanthan gum over the sauce and whisk vigorously for 30 seconds to thicken. Be careful not to add too much, a little goes a long way.
  3. Stir in 3/4 cup of the shredded sharp cheddar cheese and all of the Parmesan cheese until melted and smooth. Season the sauce with salt and black pepper to taste, starting with 1/4 tsp each and adjusting as needed.
Assemble and Bake
  1. Return the cooked chicken and sautéed vegetables to the skillet with the creamy sauce. Stir gently to combine everything thoroughly, ensuring the chicken and broccoli are well coated.
  2. Pour the mixture into the prepared 9×13 inch baking dish, spreading it evenly. Sprinkle the remaining 1/4 cup shredded sharp cheddar cheese over the top.
  3. Bake for 20-25 minutes, or until the casserole is bubbly around the edges and the cheese on top is melted and lightly golden.
Serve
  1. Remove from oven and let stand for 5 minutes before serving. Garnish with fresh chopped parsley.

Notes

For a spicier kick, add a pinch of red pepper flakes to the sauce. You can also vary the vegetables – cauliflower, spinach, or mushrooms would work well. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the microwave or oven.

Pro Tips for Making This Low Carb Chicken Casserole

Making a wonderful Low Carb Chicken Casserole is all about those little touches that elevate it from good to absolutely divine. My aim is always to make sure you feel confident and joyful in the kitchen!

My Secret Trick: I always sear my chicken breasts lightly before cubing them for the casserole. This extra step locks in moisture and adds a beautiful depth of flavor that a simple boil or bake just can’t achieve. Trust me, it makes all the difference!

To achieve that perfectly creamy texture without excess flour, I always recommend tempering your cream cheese with a little warm chicken broth first. This ensures a silky-smooth sauce without any lumps, creating a truly luxurious base.

Don’t be shy with your seasonings! I find a generous hand with garlic powder and black pepper really brings out the best in both the chicken and the broccoli. Always taste and adjust before baking, just as my grandmother taught me – your palate is your best guide.

For that irresistible golden-brown crust, don’t rush the final bake. Give the casserole ample time in the oven, especially during the last few minutes, to let the cheeses melt into a beautiful, bubbly, and slightly crispy topping.

Fun Variations for Low Carb Chicken Casserole

I adore how a recipe can be a canvas for creativity! This Low Carb Chicken Casserole is wonderfully adaptable, inviting you to play with flavors and ingredients. My friend, Emily, loves changing things up, and she always inspires me to think of new twists.

Vegetable Swaps

Feel free to introduce other low-carb vegetables. My sister adores adding sautéed mushrooms or spinach to her casserole for an extra layer of earthiness. You could also try green beans or cauliflower florets. Just ensure they are tender-crisp before adding them to the mix.

Spice It Up!

For those who enjoy a little kick, a pinch of red pepper flakes or a dash of hot sauce in the creamy sauce can transform this comforting dish into something with a lively zing. It’s a wonderful way to personalize your experience.

Cheese Please!

While cheddar and Parmesan are classics, don’t hesitate to experiment with different cheeses. A smoky provolone, a tangy Monterey Jack, or even a little cream cheese swirl (beyond the base) could add a unique flavor profile that delights your taste buds.

What to Serve With Low Carb Chicken Casserole

A hearty, comforting dish like our Low Carb Chicken Casserole deserves companions that complement its richness without overpowering it. When I serve a meal like this, I think about balance and how to make the whole plate feel complete and satisfying.

I love serving this casserole with a simple, crisp green salad tossed in a light vinaigrette. The fresh, tangy greens cut through the richness beautifully, making each bite of the creamy casserole even more enjoyable. It’s a classic pairing that always works!

My mom always says a sprinkle of fresh herbs can elevate any dish, and she’s right! A scattering of fresh parsley or chives over your warm casserole just before serving adds a lovely burst of color and a fresh, aromatic finish.

For a slightly heartier side that’s still low-carb, consider some steamed asparagus or a side of roasted Brussels sprouts. Their slightly bitter notes create a wonderful contrast, making the meal feel more gourmet and special without much fuss.

How to Store Low Carb Chicken Casserole

To ensure your delicious Low Carb Chicken Casserole remains as delightful tomorrow as it is today, proper storage is key. It’s so lovely to have leftovers that taste just as wonderful, ready for a quick and easy meal.

Fridge Storage

Once cooled completely, transfer any leftover casserole to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days. I always recommend placing a piece of parchment paper directly on the surface of the casserole before sealing the container; this helps prevent it from drying out.

Freezer Tips

If you’re planning ahead or have a larger batch, this casserole freezes well! Portion it into individual freezer-safe containers or a larger foil-wrapped dish. It can be stored in the freezer for up to 2-3 months. Thaw overnight in the fridge before reheating.

Reheating Instructions

To reheat, you can use the microwave for individual portions, gently warming until heated through. For a larger amount, cover it with foil and bake in a preheated oven at 350°F (175°C) until warm, removing the foil for the last few minutes if you want to crisp up the topping again. A splash of extra broth or cream can help maintain moisture.

Nutritional Benefits

This delightful Low Carb Chicken Casserole offers a fantastic way to enjoy a satisfying meal while keeping carb counts in check. Packed with protein from the chicken and wholesome vitamins from the broccoli, it’s a treat that’s both nourishing and incredibly flavorful, embodying my belief that healthy eating can still be utterly delicious.
