Chicken Cordon Bleu Casserole FAQ's
Yes, and it works great! Broccoli, mushrooms, or diced onion are all good options. Use about 2 cups total, and if you're using frozen vegetables, thaw and drain them first so the casserole doesn't get watery.
No, milk will thin out the mixture too much and you'll lose that creamy texture. Sour cream is what keeps the casserole rich and thick.
Any cooked chicken will work here-rotisserie chicken, leftover baked chicken, or even poached chicken. This is a great clean-out-the-fridge situation.
Yes, you can swap Swiss cheese for mozzarella, provolone, or even Monterey Jack. The flavor will change slightly, but it will still be creamy and delicious.
Deb's tip for a great casserole
Don't add the cracker topping until right before baking. It might be tempting to toss everything together and call it done, but adding the buttery cracker topping at the last minute is what keeps it crisp instead of soft and soggy.
That little bit of timing makes the difference between "good casserole" and "everyone sneaking seconds straight from the pan."

Can I substitute thick plain Greek Yogurt for the sour cream? Have all the other ingredients on hand right now, except for the sour cream.
Debra Clark says
Yes, you can substitute plain Greek yogurt for the sour cream Sue. It will be slightly more tangy, and totally compliment the casserole. Enjoy the recipe!!
