• For ranch dressing: Mix together mayo, sour cream, and Italian seasoning if you’re not a fan of ranch.
Step-by-Step Instructions for Easy Low Carb Chicken Casserole
Making this casserole is straightforward and quick. Just follow these simple steps:
- Prepare the Vegetables: Preheat your oven to 375°F (191°C). If you’re using fresh broccoli, blanch it by boiling for 1-2 minutes until it’s bright green, then drain well. If you’re using frozen spinach, thaw it completely and squeeze out any excess water.
- Combine the Ingredients: In a large bowl, mix the chicken, bacon, garlic, prepared vegetables, ranch dressing, mozzarella cheese, and half of the cheddar cheese. If you like, you can add some ranch seasoning mix for extra flavor.
- Transfer to the Casserole Dish: Pour the mixture into a greased 9×13-inch casserole dish. Spread the mixture evenly.
- Add the Cheese Topping: Sprinkle the remaining shredded mozzarella and cheddar cheese evenly over the top of the casserole.
- Bake and Serve: Bake the casserole in the preheated oven for 15-20 minutes, or until the top is golden and bubbly. Remove from the oven, let it cool slightly, and serve hot.

Tips & Tricks for the Best Easy Low Carb Chicken Casserole
To ensure your casserole turns out perfectly every time, here are a few helpful tips:
- Avoid excess moisture: Be sure to thoroughly drain the broccoli and spinach. Excess moisture can make the casserole watery, so consider pressing out any remaining liquid from the spinach before mixing it in.
- Cheese layering: Reserve half of the cheese for the last 10 minutes of baking. This will give you that perfectly melted and golden top layer without burning the cheese.
- Check the doneness: Ensure the casserole is heated through by inserting a knife into the center — it should come out hot to the touch.

- Side dishes: Serve with a simple side salad or roasted vegetables like cauliflower or zucchini for an extra veggie boost.
