How to Make Creamy Low Carb Chicken Casserole

Preheat the oven to 375°F (191°C). This is the perfect starting point for creating your creamy masterpiece!
Prepare vegetables by thawing the frozen spinach and squeezing out excess water. If using fresh broccoli, par-boil for 1-2 minutes until it's bright green and crisp, then drain.
Mix together in a large bowl: your chicken, bacon, prepared vegetables, minced garlic, ranch dressing, and both mozzarella and cheddar cheeses. This should create a solid base of creamy deliciousness!
Combine well, making sure everything is evenly coated, but remember to reserve half of the cheese mixture for the topping-you want that golden melt at the end!
Transfer the mixture to a 9×13 inch casserole dish, spreading it out evenly, and top with the reserved cheese. It's going to get wonderfully warm and bubbly!
Bake for 15 minutes or until the top is hot and bubbly. Let the casserole cool slightly before serving; it will be worth the wait!

Optional: Garnish with fresh parsley for a pop of color and added freshness.
