How to Make Low Carb Chicken Casserole
Preheat the oven to 450°F. Start by lining a rimmed baking dish with foil and greasing it lightly. Arrange the chicken breasts in the pan and give them a good spray of avocado oil, seasoning them with salt and pepper. Bake until cooked through, about 20 minutes.
Prepare your casserole dish. While the chicken is baking, grease a 2-quart casserole dish. In a large bowl, combine the mayonnaise, sour cream, Dijon mustard, minced garlic, salt, pepper, thyme, paprika, cayenne, and ½ cup of shredded cheddar. Mix well!
Cool and cut the chicken. Once the chicken is done, take it out of the oven and let it cool slightly. When it’s easier to handle, cut it into cubes or shred it. Add the chicken to the bowl with the creamy mixture and toss gently until coated.
Transfer the mixture. Pour the chicken and creamy mix into the prepared casserole dish, spreading it evenly. Top it all off with the remaining ½ cup of shredded cheddar. Bake until the cheese is melted and the casserole is heated through, around 10 minutes.
Garnish with flavor! Sprinkle sliced scallions and bacon bits over the top of your casserole right before serving. Serve hot and enjoy every bite!
Optional: A sprinkle of fresh parsley adds a beautiful touch!

Expert Tips for Low Carb Chicken Casserole
Quality Ingredients: Always opt for fresh chicken breasts. Frozen options may not bake evenly, affecting the overall flavor of your low carb chicken casserole.
Cutting Technique: Allow the chicken to cool slightly before cutting. This prevents dry, shredded bits and ensures tender, juicy pieces in your creamy mix.
Mixing Uniformly: When combining the creamy mixture, stir thoroughly to avoid clumps. A well-mixed batter leads to an even distribution of flavors in the casserole.
Cheese Variations: Feel free to experiment with different cheeses like pepper jack for added heat or mozzarella for a milder flavor. Just maintain that creamy consistency!
Baking Time: Keep an eye on the casserole while it bakes. Remove it from the oven once the cheese is melted and bubbly to avoid overcooking the chicken.

To prevent this, make sure to monitor the chicken closely and pull it from the oven as soon as it reaches an internal temperature of 165°F. If you find yourself with a dry casserole, consider adding a splash of chicken broth to the dish while reheating. This will help bring back some moisture and flavor.
