​Easy Keto Creamy Chicken and Vegetable Casserole Ingredients

There are twelve bowls of various size. There is a large white bowl with pieces of green broccoli and white cauliflower. There is another large white bowl with shredded cooked chicken in it. There are two medium white bowls. One has white shredded cheese in it and one has orange shredded cheese in it. There is a small white bowl with white cream cheese in it. There are two small clear glass bowls. One has white thick cream in it, the other has white milk in it. There is a smaller white bowl with chopped green onions in it. There are four very small bowls. One has ground black pepper in it, one has light yellow onion powder in it, one has yellow mustard in it and one has light brown garlic powder in it. All the bowls are on a white marbled surface.

Simple Ingredients Needed

Cauliflower and Broccoli Florets: I like to use fresh broccoli and cauliflower florets. (see Recipe Tip)

I don’t recommend using frozen vegetables for this keto casserole.

Frozen broccoli and cauliflower may cause the casserole to be mushy after baking. 

Shredded Chicken: I prefer to use a rotisserie chicken for the convenience.

Feel free to use any type of chicken. Boneless skinless chicken breasts is a great option.

For a more hearty dish try using boneless skinless chicken thighs.

Cheese Sauce: This is what makes this delicious recipe creamy!

It is a combination of sour cream, heavy cream, cream cheese, shredded cheese, and a little bit of dijon mustard.

A great option for the sour cream and heavy whipping cream is ranch dressing.

If using ranch dressing you may want to adjust the seasonings.

Seasonings: A blend of onion powder, garlic powder, black pepper, and salt. Adjust the amounts to your personal preference. 

Shredded Cheese: When it comes to the cheese, all kinds of cheese can be used.

I prefer to mix cheddar cheese in the sauce and sprinkle mozzarella cheese over the top.

Monterey jack cheese and parmesan cheese are also delicious in this great recipe.

Optional Toppings: One of my favorite topping on the Keto Creamy Chicken and Vegetable Casserole is chopped scallions.

If you like a crunchy topping, try some crumbled bacon or crushed pork rinds!

The best way to store any leftover casserole in an airtight container and in the fridge for 4 to 5 days.
