Tips and tricks

It is best to cook the chicken right before you plan on making the Cordon Bleu casserole as the chicken can dry out if left for too long.

You can either roast or grill the chicken, leave it to rest for 10 minutes after cooking, and then chop up for the casserole.

You can easily change up the recipe by adding in some fresh herbs to the dijon sauce or add some crushed pork rinds to the top before baking for a crispy top.

Can the casserole be prepared ahead?

Yes! You can definitely prepare this entire meal a few days before and store in the refrigerator. You can also cover with plastic wrap and freeze for up to 4 weeks. This makes dinner as easy as turning on the oven!

To reheat from frozen, allow the casserole to thaw completely. Then bake as normal and dinner is served.

You might wonder how the creamy sauce holds up after it has been frozen. Since everything was mixed together, the dairy will have stabilized and is fine to freeze without worrying about it separating when reheating.

What to serve with this casserole

The cordon bleu casserole is a very hearty and rich main course so you can complement it with a salad or some simple vegetable side dishes. Steamed or roasted broccoli, cauliflower, zucchini, carrots, or mushrooms work well.
