Step‑by‑Step Instructions for Low Carb Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (191°C). This crucial step ensures that your Easy Low Carb Chicken Casserole bakes evenly, resulting in a bubbly, golden finish. While the oven preheats, gather your ingredients and prepare your workspace, setting the stage for a smooth cooking experience.
Step 2: Prepare the Vegetables
If using frozen broccoli, thaw it and drain any excess water. For fresh broccoli, blanch it for about 2–3 minutes in boiling water until bright green, then immediately transfer it to ice water to stop the cooking process. This step ensures your veggies are tender yet still crisp and vibrant, ready to mingle in the casserole.
Step 3: Mix the Filling
In a large mixing bowl, combine the cooked chicken, crispy bacon, prepared broccoli, minced garlic, ranch dressing, and both shredded mozzarella and cheddar cheeses. Stir everything together until evenly coated, and if desired, adjust the seasoning by adding a bit of ranch seasoning. The mixture should look creamy and inviting, brimming with flavor.
Step 4: Transfer to Casserole Dish
Grease a 9×13-inch casserole dish with cooking spray or a light coat of oil. Pour the chicken mixture into the dish, spreading it out evenly using a spatula. This helps ensure that every scoop of your Low Carb Chicken Casserole gets an even distribution of chicken, veggies, and cheese goodness.
Step 5: Add Topping Cheese
Sprinkle the additional mozzarella and cheddar cheeses generously over the top of the casserole mixture. This layer of cheese plays a pivotal role in creating that irresistible gooey crust as it bakes, adding a delightful texture and flavor contrast to the hearty fillings below.
Step 6: Bake the Casserole
Place the casserole in the preheated oven and bake for 15–20 minutes, or until it’s hot, bubbly, and the cheese on top has turned a beautiful golden brown. Keep an eye on it towards the end to ensure the cheese doesn’t burn. You’ll know it’s ready when the edges are bubbling and the aroma fills your kitchen.
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for about 5–10 minutes. This waiting period not only helps with serving but also allows the flavors to set beautifully. Serve warm, and enjoy the hearty, cheesy comfort of your Homemade Low Carb Chicken Casserole with family and friends!
