Chicken Brussel Sprout Casserole with walnuts and bechamel sauce, a delicious and low-carb dish for the whole family. A great choice for your Thanksgiving or Christmas dinner menu. It’s very easy to make, and a great alternative to the plain boiled brussels.
Brussels sprouts are very popular in the UK, many people will say that the Christmas menu would not be complete without them. They are a great accompaniment to any roast and can be enjoyed on their own or in stir fries or baked with other ingredients.
Brussels sprouts are the mini version of cabbages, have a lovely green colour and a bitter-sweet nutty flavour, being at their best in the winter months. Although you can find frozen ones as well, the fresh Brussels sprouts taste a lot better, and they keep their shape when you cook a lot better too.
Unlike other vegetables, they are quite inexpensive and are easily available in any supermarket in the cold months. You can either buy them fresh or frozen, but either way, they can be cooked really fast.
The fresh ones, however, are super tasty once the cold season starts. I don’t really have much of them in summer, as with other seasonal vegetables, I would rather consume them when they are at their best.
How to make CHICKEN brussel sprouts casserole
- First, we need to cook the chicken.
If you have any leftover chicken or rotisserie chicken, that’s great, this step can be skipped. If not, cut the chicken breasts into pieces, add them to a bag together with the paprika, salt and pepper, and shake well to coat.
- Grill/Fry for 5-6 minutes until cooked through, then add the chicken pieces to an oven-proof dish, and top with grated cheese.
- To boil the brussels sprouts, remove the tough ends and boil in salted water until tender
- Next, make the cheese sauce. Melt the butter in a pan, add the flour, mix well, and slowly pour the milk in whisking continuously until it thickens.
- Add the dijon mustard, season to taste, and add more grated cheese.
- Pour the sauce over the brussels sprouts, chicken, add the walnuts, then top with more grated cheese, and bake for 10-15 minutes until the cheese is melted.
What can you replace the chicken with?
You can add cooked bacon, ham, turkey, beef, or any other meat of your choice. For a vegetarian option, you can add sauteed mushrooms or even meat-free quorn pieces. Make sure the brussels sprouts are cooked beforehand, otherwise they will not have time to soften in the oven, since the cheese melts quickly.
.Or you can just leave the brussels sprouts on their own, just coated in this delicious cheese sauce, they will still be the next level up if you are to compare it to the plain boiled sprouts, which could be seen as pretty boring.
Alternatively, how about my Pan-Fried Brussel Sprouts with Bacon, Garlic and Parmesan? They are super quick to make, and so delicious!

This sounds really good, lots of different textures that would add a nice crunch!
Thank you! 🙂
I adore Brussels sprouts, and your recipe looks really delicious. We always grew our own sprouts until we moved house to a smaller garden. i must say I haven’t found any we’ve bought to have the same, lovely nutty taste. But you are right, Christmas dinner wouldn’t be the same without them. ou’re also right about how heavy Christmas dinner is. So this recipe would be excellent for sometime over the holiday. I like the idea of using walnuts. i love all nuts! Thanks for this one, Daniela.
Thank you, Millie. I am glad you like my recipe 🙂
Gorgeous looking! Healthy too!
Thank you ?
Sprouts are THE best, I honestly wish I could have them all year round! Great recipe
Thank you! 🙂 they are lovely, the simplest dishes with the simplest ingredients can sometimes be the best
No idea what a “knob” of butter is and can’t begin to know how much 25g of cheese might be……….other than that it looks pretty good…….
Hello, thank you for your comment. In the UK we usually call a knob of butter a small amount, like let’s say a teaspoon or so. I have updated the recipe to reflect the change, as well as the cheese one. If you click on the US Customary link in the recipe card, you will see the measurements displayed in cups and ounces.
Had leftover chicken and stock, so used both. Pan roasted the Brussels sprouts and used the drippings to make the sauce. Excellent flavor!
Glad you enjoyed it!
Just made this last night and it was yummy , thanks a keeper 👍
I am glad you liked it!
