Step-by-Step Instructions
Step 1: Prepare the Chicken and Broccoli
Cook and shred the chicken if not already prepared.
Steam or blanch the broccoli until just tender but still bright green.
Set aside.
Step 2: Make the Alfredo Sauce
In a saucepan over medium heat, melt the butter.
Add the minced garlic and sauté for 30 seconds until fragrant.
Pour in the heavy cream and bring to a simmer.
Whisk in the parmesan cheese, salt, pepper, and nutmeg (if using).
Simmer gently, whisking constantly, until thickened—about 4–5 minutes.
Step 3: Assemble the Bake
In a large mixing bowl, combine the shredded chicken, broccoli, mozzarella, and parmesan cheese.
Pour the Alfredo sauce over the top and mix until everything is well coated.
Step 4: Transfer to Baking Dish
Spread the mixture evenly in a greased 9×13-inch baking dish.
Sprinkle shredded cheddar cheese over the top.
Step 5: Bake
Preheat your oven to 375°F (190°C).
Bake uncovered for 20–25 minutes, or until bubbly and golden.
Step 6: Cool & Serve
Let cool for 5 minutes before serving.
Garnish with additional parmesan or chopped parsley if desired.
Tips for Success
Don’t Overcook the Broccoli – Keep it crisp-tender so it doesn’t get mushy.
Use Freshly Grated Cheese – Melts better and gives a smoother sauce.
Whisk the Sauce Constantly – Prevents burning and keeps it silky.
Shred the Chicken Well – Smaller pieces mix evenly into the bake.
Customize It – Add mushrooms, bacon, or even spinach for extra flavor and variety.
Serving Suggestions
With a Simple Green Salad – Light and refreshing side.
With Cauliflower Rice – For an extra low-carb option.

As a Meal Prep Dish – Portion into containers for easy grab-and-go lunches.
