How to Make the Recipe

Step 1

Preheat your oven to 375°F (190°C) and grease a 9×13-inch casserole dish with cooking spray.

Step 2

In a large mixing bowl, combine the cooked chicken, chopped bacon, minced garlic, ranch dressing, and half of the mozzarella and cheddar cheeses. Stir until everything is well coated.

Step 3

If you’re using broccoli, steam or blanch the broccoli florets until tender. If using spinach, make sure the spinach is thawed and fully squeezed of excess moisture. Add your chosen vegetable to the chicken mixture and stir to combine.

Step 4

Transfer the mixture into the prepared casserole dish and spread it out evenly.

Step 5

Top with the remaining mozzarella and cheddar cheeses.

Step 6

Bake in the preheated oven for 20–25 minutes, or until the casserole is bubbly and the cheese on top is golden and melted.

Step 7

Let the casserole rest for 5 minutes before serving. Garnish with fresh herbs or extra bacon if desired.

Tips for Making the Recipe

• Use Rotisserie Chicken: For an even quicker meal, use store-bought rotisserie chicken to save time.
• Don’t Overcook the Chicken: If you’re cooking chicken specifically for this casserole, avoid overcooking it to keep the meat tender and juicy.
• Fresh or Frozen Veggies: Either fresh or frozen broccoli or spinach will work perfectly—just be sure to drain frozen spinach well to avoid excess moisture.
• Customize the Cheese: Feel free to mix in other types of cheese like Monterey Jack, gouda, or cream cheese for a richer flavor.

How to Serve

This casserole is hearty enough to be a meal on its own, but it pairs beautifully with a side salad or roasted vegetables. If you prefer a lighter option, serve it with a fresh, crisp green salad or a side of sautéed zucchini or asparagus. You could even serve it with some low-carb garlic bread or cauliflower rice for a more filling meal.

Make Ahead and Storage

Storing Leftovers
