Chicken Mornay Casserole

Chicken Mornay is a delicious low-carb dinner. An oldie but goodie chicken casserole out of my recipe box.  This casserole is a quick N easy, Healthy version of chicken comfort food. It is low carb for our keto dieters, but not low cal. 🙂

Your family will enjoy this Cheesy chicken casserole. It’s bursting with broccoli cheese goodness. 

The layer of broccoli replaces the carbs of pasta, rice or other ‘stick to your ribs’ fillers with excellent results.

A homemade sauce adds a level of customization and extra good flavor to this delicious recipe.

This chicken casserole recipe is really, really good and pretty simple to make.

I can’t imagine how it got so lost in my recipe collection. Well Blush….I do know how it got lost in that enormous pile of recipe cards.

When I found it and made it again it was amazing! So we put it on the blog with a recipe demonstration video so we can find it, and so can you.

Chicken Mornay a delicious low carb casserole. The broccoli is so good with this Mornay sauce, chicken and cheese. Comfort food at it’s best!

It takes a bit of time to chop up a fresh head of broccoli. Use pre-chopped flowerets from the store to hurry up the recipe a little.

You can also use Frozen Organic Broccoli florets. But you need to thaw the broccoli before you layer it in this casserole or your oven time will have to be increased.

We like frozen broccoli in the off season and we ate all our broccoli fresh from our garden last year.

There wasn’t enough to freeze.  You can also find fresh broccoli precut in bags at the store if you really hate chopping.

Making your own mornay sauce may sound scary but believe me it’s not hard at all. Just whisk a few things in a pot over heat. Remove! Not so bad. 

Chicken Mornay Recipe Notes:

Recipe TIPS:

Using canned chicken very convenient, fast and easy BUT it may add too much saltiness to the recipe for you. Choose a  low sodium canned chicken. 

OR

If you prefer to use raw chicken breasts you will need about 1 1/2 lbs. of skinless boneless chicken breasts. Chop them up into 1/2 inch pieces and precook in your skillet over medium heat.

You will also need to add a 1 cup of chicken broth and seasonings (1 tsp. of salt) to your taste to get the flavor.

With the canned chicken and cheese you won’t need any extra salt in this recipe.  Today I have one puny little chicken breast that needs using so I cut it up and pan fried it to just done before adding it in with a 12 oz. can of chicken for this recipe.

I am always looking for ways to use up my small extras in casseroles. That’s what casseroles are for.

Use THIS  Healthy Homemade Mayonnaise Recipe To improve the fats in this casserole. This mayo is REALLY flavorful, you can make it about three minutes and it uses avocado oil. WAY better than store bought.

This recipe is a snap when you use store bought rotisserie chicken meat. Most store deli’s have it now. I buy mine most often from Costco Pulled rotisserie chicken meat.

Purchased shredded seasoned and cooked chicken adds a lot of flavor to recipes like this one. However, if you want to cut the salt in this chicken casserole, you can boil a chicken debone it and shred the meat.

Use your own seasoning and go light on the salt. Another thing I like to do is make chicken bone broth in my instant pot, in that process I can make shredded chicken and freeze it for later.

Can I substitute half and half for the evaporated milk. Evaporated milk has too much lactos which is sugar, which is carbs. I'm also allergic to lactose and half and half has very little lactose.

Hi Kazy, Half and half or even heavy cream should be a good substitute for the evaporated milk. Thanks for asking. I hope you enjoy the recipe. Have a wonderful day. :)
