Keto Millionaire Chicken Casserole

As someone who loves comfort food, I always look for ways to elevate classic dishes and give them a keto twist. 

If you’re following a keto diet, you know how important it is to find recipes that are both delicious and compliant with your dietary restrictions. 

Most traditional creamy chicken casserole recipes use cream of chicken soup and crushed Ritz crackers, both of which are loaded with carbs and preservatives and are not a good idea for anyone watching their carbs and avoiding gluten. 

Plus, it’s an easy recipe that works well on busy weeknights or hectic weekends when you need a quick dinner.

That’s why this million-dollar keto chicken casserole is such a great recipe. Plus, it’s a yummy low carb chicken casserole dish the entire family will love, even if they are not on a ketogenic diet.

Whether you’re hosting a dinner party or want to treat yourself to something special, this casserole will surely impress.

Make the recipe part of your meal planning; it’s sure to become a family favorite.

​The good news is that it clocks in at only 4.3 net carbs per serving and uses simple ingredients that are easy to source.

Step-by-Step Cooking Instructions

Preparing Your Ingredients

Before assembling the casserole, it’s important to have all of your ingredients prepped and ready to go. Start by shredding half of a rotisserie chicken and seasoning it with salt, black pepper, onion powder, and garlic powder.

Then, dice a small onion and set it aside.

Next, cook a 12-ounce package of frozen cauliflower rice according to the instructions on the package. Once cooked, set it aside.

Finally, prepare the cream sauce mixture by melting the unsalted butter in a small pot over medium heat. Add the softened cream cheese, cut into small pieces, and the heavy whipping cream—season with salt, onion powder, garlic powder, and black pepper.

Cook until the cream cheese is fully melted and incorporated into the sauce.

Assembling This Simple Chicken Bake Casserole

To assemble the casserole, start by buttering a 10 x 10-inch baking pan. Add the shredded chicken to the bottom of the pan, followed by the diced onions. Next, add the cooked cauliflower rice on top of the onions.

Finally, pour the cream sauce mixture over the casserole, making sure it covers all of the ingredients evenly. Top with the shredded cheddar cheese.

Baking To Perfection

Preheat the oven to 350 degrees F. Bake the casserole for 25-30 minutes or until it’s hot and bubbly and the cheese is golden brown.

Once done, remove it from the oven and let it cool for a few minutes. Garnish with chopped parsley and chopped green onions.

Storage Tips

If you have any leftovers, store them in an airtight container in the refrigerator for up to three days. Place the desired portion in the microwave or oven until heated. 

If you want to freeze the casserole, let it cool completely before placing it in a freezer-safe container. It can be stored in the freezer for up to three weeks.

When reheating from frozen, let the casserole thaw in the refrigerator overnight before reheating in the oven. This will ensure that the casserole heats evenly and doesn’t dry out.

You can give this keto million dollar chicken bake a flavor twist by topping it with pieces of crispy bacon or add a layer of pork rind crumbs and parmesan cheese for a crunchy topping.
