This quick and easy keto chicken broccoli casserole recipe with cream cheese is made completely from scratch without relying on a canned soup base. It’s gluten-free, low-carb, and absolutely delicious!
Casseroles are super easy dinners that are great for the whole family. However, finding healthy low-carb chicken casserole recipes isn’t always simple. That is why I made this recipe!
Many popular casserole recipes use canned soup, white rice, and are topped with breadcrumbs. These are all empty starches, which you obviously want to avoid since you’re eating low-carb.
If you’re a casserole person, you’ve probably been hoping to find a chicken dinner casserole that doesn’t use any canned soup. Why? Because they typically contain starches that aren’t appropriate for a lower-carb diet.
You certainly don’t need the hidden carbs that come in creamy soups, nor do you want the chemicals in those premade cans anyhow.
And, that’s why this keto chicken broccoli casserole recipe is so perfect!
It’s inspired by a similar recipe that’s a gem from an old cookbook in my collection, just much healthier.
I also included a secret ingredient in the casserole that’s not the norm in most chicken and broccoli bakes: parmesan cheese. The slightly nutty, wholly rich flavor of parmesan enhances the flavors of the chicken and broccoli in a unique and mouth-watering way!
Ingredients Needed For Keto Broccoli Chicken Casserole
You’ll love that there are no fancy ingredients in this meal. Easy weeknight casserole dinners need to be made from readily on-hand ingredients.
This dinner is a simple low-carb broccoli casserole with cream cheese. You’ll be using food that’s easy to find in any grocery store and quite possibly already in your pantry, fridge, and freezer.
Overall, it’s pretty simple to toss this together in your favorite casserole baking dish. Broccoli, chicken, and mushrooms are the stars of this easy recipe. However, flavorful spices, cheeses, and liquids will make your cream keto cream sauce a tantalizing substitution to replace canned condensed soup.
I used boneless, skinless, chicken breasts and then chopped them up really small. You can also use boneless, skinless chicken thighs.
I used both olive oil and butter. Use unsalted butter if you can. If you use salted butter, just cut back on how much salt you add to the dish.
You can substitute avocado oil for olive oil if you have it on hand!
I love how the garlic and onion add taste and aroma to this recipe. I always use them together whenever I cook.
I only used a few spices in this recipe. All you need is some salt, pepper, and tarragon.
For the liquid ingredients, I used both white cooking wine and chicken broth!
Instead of white cooking wine, you can use lemon juice. Chicken stock can be substituted for chicken broth.
The only veggies I used are mushrooms and broccoli, but you can add your favorite low-carb veggies to this recipe. Cauliflower and zucchini will taste pretty delicious with it!
Fresh or frozen broccoli will work, depending on what’s easiest for you.
Combine cream cheese, sour cream, and parmesan cheese. This makes the casserole extremely creamy and rich without being full of extra salt or carbs.
Have fun with the type of cheese you use. I prefer parmesan cheese, but any other hard cheese will work too. Try it with Romano cheese!
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
- Brown the chicken first. Doing this will add some extra flavor to the recipe, especially when you use the same skillet for making the sauce and cooking the mushrooms.
- Save time and use rotisserie chicken. You might also use shredded chicken if you’ve already got some prepped in your fridge, but it won’t be as hearty to bite into.
- Use cauliflower rice. If you think you’ll miss the white rice, you can even add cauliflower rice to the creamy sauce, subtle broccoli, and savory chicken.
How To Make Keto Chicken Broccoli Casserole
All of the instructions are in the printable recipe card at the bottom of the post. First, here are some helpful tips that I hope teach you a little more about this recipe.
Slice The Chicken
The chicken will cook so much faster if you chop it into small bites first. This one step will save you lots of time.
Cook The Chicken
Next, cook the chicken with garlic and onion. Use both olive oil and butter. When you fry them together, the chicken will take on the garlic and onion flavors!
After the chicken is no longer pink, add the rest of the ingredients and fry them for a few minutes.
Bake The Casserole
Finally, put everything in a casserole dish and top with parmesan cheese. Bake it for about 25 minutes. That's it!
What To Serve With Chicken Broccoli And Cream Cheese
Frequently Asked Questions About Chicken Broccoli Casserole
Before we get to the recipe (just a little further below), here are some questions people often ask about it.
Can you make this keto casserole in the slow cooker?
Absolutely! While this recipe is written for the oven, it’s actually quite easy to make in the Crock-Pot.
There would just need to be some simple adjustments made to make this low-carb chicken broccoli casserole with cream cheese and chicken in your slow cooker.
To slow cook, all you’d have to do is toss all the ingredients into your crock. To make clean up easier, you can use a liner but it’s not essential. Then, let it sit in the crockpot for 6-8 hours on low.
How do you make this recipe in the Instant Pot?
The pressure cooker would be very similar to the crockpot. You’ll want to cook the chicken, broccoli, mushrooms, broth, wine, and spice together first. Wait until the end to add in the cream cheese and sour cream though, because the dairy separates when cooked under pressure.
What are some low-carb crunchy toppings I can add to my keto chicken broccoli casserole?
Sometimes you want the comfort food experience of a creamy casserole with a crunchy topping.
If you have any keto bread in the refrigerator or freezer, it would make a good crumbled topping for this low-carb broccoli casserole. Just lightly toast it, crumble, and then stir it in with some melted butter.
My homemade breadcrumb recipe using pork rinds will also work in a similar way.
If you’d like to add some parmesan to the crumbly topping, that adds a nice flavor that pairs well with the rest of the casserole. So does a dash of parsley sprinkled in!
How do you store this casserole?
This casserole is delicious served piping hot out of the oven! You can make it up ahead of time and just cook before serving. My family loved it and I have no doubt yours will, too.
In fact, it’s a great freezer dinner to make ahead of time and it’s easy to pull out for a busy weeknight meal the whole family will enjoy.
If you have any leftovers, they will keep in the fridge for several days and can be reheated in the oven or microwave. If you microwave them, sprinkle with a few drops of water and heat up lightly-covered to keep it from drying out.
Broccoli is one of my favorite vegetables. And, it goes perfectly with chicken. What’s your favorite casserole dish to make with broccoli and chicken?
