Ingredients

Main

  • 2 cups cooked chicken (shredded or diced)
  • 3 cups broccoli florets (fresh or frozen)
  • 2 cups cooked pasta OR rice

Creamy Sauce

  • 2 tablespoons butter
  • 2 tablespoons flour
  • 2 cups milk
  • ½ cup heavy cream (optional but extra rich)
  • 1 cup chicken broth
  • 1 teaspoon garlic powder
  • ½ teaspoon onion powder
  • Salt & black pepper

Cheese

  • 2 cups shredded mozzarella or cheddar
  • ½ cup parmesan

Topping (optional but amazing)

  • ½ cup breadcrumbs or crushed crackers
  • 1 tablespoon melted butter
  • Fresh parsley or chives

Step 1 – Prep Everything First

Preheat oven to 180°C (350°F).

Cook pasta or rice.

Steam or blanch broccoli for 2–3 minutes (just slightly tender, not mushy).

Cook or shred your chicken.

Having everything ready makes assembly super fast.

Step 2 – Make the Creamy Sauce

In a pan:

Melt butter → add flour → whisk 1 minute

This creates a roux (thickener).

Slowly pour in milk + broth while whisking.

Cook until thick and creamy.

Then add:

  • Cream
  • Garlic powder
  • Onion powder
  • Salt
  • Pepper

Simmer 2–3 minutes.

Now stir in 1 cup cheese until melted.

Boom.

You just made homemade cheese sauce 😋

Way better than canned stuff.

Step 3 – Combine Everything

In a big bowl:

Add:

  • Pasta/rice
  • Chicken
  • Broccoli
  • Sauce

Mix gently until coated.

It should look creamy and loaded.

If it looks too thick, add a splash of milk.

Step 4 – Assemble

Pour mixture into greased baking dish.

Top with:

  • Remaining cheese
  • Breadcrumbs mixed with butter

That topping gives you crispy + cheesy combo. So good.

Step 5 – Bake

Bake for:

20–25 minutes

Until:

  • Cheese melted
  • Top golden brown
  • Edges bubbling

Optional:

Broil 2–3 minutes for extra crispy top.

Smells insane at this point. Warning 😄

Step 6 – Rest & Serve

Let sit 5–10 minutes before serving.

This helps sauce thicken and set.

Sprinkle parsley or chives.

Serve warm and creamy.

Enjoy the cheesy stretch 😍
