Preheat oven to 190°C/375°F (180°C/350°F fan/convection).

Mix Chicken Ingredients.

Heat chicken broth and milk until hot using any method (stove, microwave). Can combine together in saucepan. (Note 5)

Spread rice in 23 x 33cm / 9 x 13" ceramic or glass baking dish. (Note 6)

Sprinkle with flour, stock powder and garlic.

Add the hot chicken broth, stir until flour dissolved (some small lumps ok).

Add milk, swish rice to spread out evenly.

Spread broccoli on top, then chicken, then plonk butter on (anywhere).

Bake uncovered for 40 minutes. (Might get some browned skin on surface, that's ok)

CHECK rice before stirring - should be JUST cooked (Note 7).

Add half the cheese, stir through, being sure to get rice in the corners and edges of pan. Should be creamy and quite loose (see video).

Top with cheese, return to oven for 5 minutes until just melted.

Sprinkle with green onion, if using, then serve!
