A low FODMAP chicken broccoli and rice casserole

How to make low FODMAP chicken broccoli rice casserole?

I choose to make this casserole with broccoli and added some zucchini and the green part of leek next to it for some extra vegetables.

Next to that, I make my own white sauce and use brown rice for some extra fiber.

You can make this casserole in several simple steps:

  • Cook the rice and broccoli. Drain and put aside.
  • Cut the zucchini and the green part of the leek into pieces.
  • Fry the chicken thigh – I use chicken thigh, instead of breast because I find it a bit tastier.
  • Add the zucchini and leek and fry for a few minutes.
  • Make the white sauce with butter, gluten-free flour, stock, and lactose-free crème fraîche
  • Season with mustard, salt, and pepper.
  • Add the rice, broccoli, chicken, zucchini, and leek to the oven dish.
  • Put the sauce on top and stir everything well.
  • Sprinkle with low-fat cheese and put into the oven for 20 minutes.

And voilà, there you have your healthy chicken broccoli and rice casserole!

Broccoli and FODMAPs

Note that broccoli is limited low FODMAP and that the FODMAP content differs between broccoli heads/florets and broccoli stalks.

The amount of broccoli that I use in this recipe is a safe low FODMAP amount so one serving of this recipe is low FODMAP.

You can read more about what kinds of broccoli are low FODMAP in this blog.

What goes with this casserole?

This chicken broccoli rice casserole can easily be a dish in itself, it has brown rice as a source of carbs.

And it contains several veggies and chicken as a source of protein. So you don’t have to serve anything with it if you don’t want to.

I like serving this casserole with a salad on the side to just up my low FODMAP vegetable intake a little bit more.

Below you can find a few salad ideas:

  1. Preheat the oven to 180 degrees Celsius (350 F).

  7. Heat 1 tbsp of butter in the pan. Add 1 tbsp flour when the butter has melted.
  8. Stir until you get a roux.
  9. Add the stock gradually while you keep stirring. Keep stirring until you have a smooth sauce.
  10. Add the crème fraîche and stir again.
  11. Taste the sauce and season with 1 tsp mustard, pepper, and salt to taste.
  12. Add the chicken, vegetables and broccoli to the sauce.
  13. Divide the rice over the oven dish and put the sauce on top. Stir.
  14. Sprinkle the grated cheese on top. Put the dish in the oven for 20 minutes.
