Brussels sprouts casserole is a great way to use up leftover brussels sprouts. The casserole is easy to make, and it is a delicious and hearty dish that will please everyone at the dinner table.
One of the reasons that this recipe works so well is because the brussels sprouts are paired with chicken and cream sauce. The chicken helps to add flavor and protein to the dish, while the cream sauce adds richness and creaminess.
The casserole also has parmesan cheese, which makes it extra delicious. If you are looking for a tasty and easy way to use up your leftover Brussel sprouts, then be sure to try this casserole.

🍽 Key Ingredients
The recipe is quick to prepare if you have leftover chicken on hand, and fresh Brussel sprouts make all the difference to the overall texture and flavor.
Chicken - Use pre-cooked chicken to save yourself time. Rotisserie chicken or leftover chicken breasts are perfect for this casserole.
Cheese - The only cheese you need for the cream sauce is parmesan cheese
Brussels Sprouts - Use fresh brussels sprouts for this recipe. If you use frozen sprouts, they will become too soft after cooking, and we want delicious crisp and tender brussels sprouts.
Cream sauce - The creamy sauce is a mixture of lots of garlic, butter, and heavy cream with the parmesan cheese mixed through at the end.
Substitutions
Cream
You could swap the heavy cream for sour cream. Although, the consistency will be slightly thicker.
Cheese
If you want a stronger flavored cheese for the cream sauce, you could substitute the parmesan for gruyere cheese or cheddar cheese.
