Step-by-Step Instructions
Step 1: Prep the Chicken & Broccoli
Shred the cooked chicken into bite-sized pieces. Lightly steam the broccoli florets for 2–3 minutes until just tender but still vibrant green. Set both aside to cool slightly.
Step 2: Make the Creamy Sauce
In a large skillet over medium heat, warm olive oil or butter. Add minced garlic and cook for 30 seconds. Lower the heat and stir in cream cheese, sour cream, heavy cream, Dijon mustard, onion powder, paprika, salt, and pepper. Stir until the mixture is fully melted and smooth. Add in shredded cheddar and Parmesan. Stir until creamy and thick.
Step 3: Combine Everything
In a large mixing bowl, combine shredded chicken and broccoli. Pour the hot cheese sauce over it and stir until everything is evenly coated.
Step 4: Bake the Casserole
Grease a 9×13” casserole dish and transfer the mixture into it. Spread evenly. Optionally, sprinkle crushed pork rinds over the top for crunch or extra cheese for melt.
Step 5: Bake & Rest
Bake in a preheated oven at 375°F (190°C) for 30–35 minutes until bubbling and golden. Let it rest 10 minutes before serving.
