Best One Pot Chicken Broccoli Rice Casserole


  • 2 tbsp / 30 g unsalted butter
  • 1 tbsp olive oil
  • 1 onion , finely chopped
  • 2 garlic cloves , minced
  • 500 g/1 lb chicken thigh , cut into bite size pieces (Note 1)
  • 2 ½ tbsp flour (or 1 ½ tbsp. cornflour / cornstarch)
  • 2 cups / 500 ml milk (any, I use low fat)
  • 2 cups / 500 ml chicken broth
  • 1 ¼ cups / 225g white rice , uncooked (Note 2)
  • 1 tsp dried thyme (or other herb of choice)
  • Salt and pepper
  • 1 large head of broccoli, broken / cut into small florets (~400 – 500g / 14 oz – 1 lb) (Note 3)
  • 2 cups / 200g shredded mozzarella or cheddar (or other cheese of choice) (Note 4)
  • Finely chopped parsley , optional garnish


  1. Melt butter and heat oil in a pot over high heat. Add onion and garlic, cook for 1 minute. Add chicken and cook until it changes from pink to white. (Note 5)
  2. Turn stove DOWN to medium. Add flour and stir for 1 minute.
  3. Add half the milk, stirring as you go, and once incorporated into the flour add the rest of the milk and stir.
  4. Add broth, rice, thyme and a just pinch of salt and pepper.
  5. Stir, bring to simmer, then cover. Turn down to medium low and cook for 12 minutes.
  6. Remove lid – there should still be liquid on the surface. Working quickly, add broccoli, push down so it’s partly submerged, cover and cook for a further 3 minutes until broccoli is just cooked.
  7. Preheat grill/broiler. Remove lid and stir through half the cheese – don’t worry if it looks a bit too saucy, excess liquid gets sucked up in minutes (see video). Smooth surface, top with remaining cheese. Grill/broil until melted (or just put lid on and allow to melt with residual heat on turned off stove).
  8. Serve immediately, garnished with parsley if desired.
