Ingredients for Making Keto Chicken Alfredo Casserole
- Broccoli: To blanch broccoli, bring a large pot of salted water to a boil. Fill a bowl with ice water. Add the broccoli to the boiling water and cook for 2 minutes. Remove the broccoli with a slotted spoon and place in the ice water. Drain.
- Chicken: You may use boneless skinless chicken thighs or chicken breast. A rotisserie chicken from the grocery store is also a good option. Make sure to check the label and make sure no ingredients were added that are unsuitable for a keto diet.
- Alfredo Sauce: I like to make my own, but you can buy keto-friendly alfredo sauce too. (Don't forget to check the label - some have flour in them.)
- Xanthan Gum: This thickens the sauce a bit.
- Cheese: I use a blend of mozzarella and parmesan cheese. Feel free to mix this up if you like. Swiss cheese would be nice in place of the mozzarella.
Variations
Feel free to play with the vegetables here! Cauliflower, sauteed spinach, and zucchini are all excellent options.

As an amazon associate, I earn from qualified sales.
- Vegetable Noodles are always a great alternative to pasta. Zucchini noodles, cabbage noodles, and spaghetti squash all make great options.
- Shirataki Pasta (also called miracle noodles), is a low carb option loved by many. It is made from the fiber from the konjac plant root. You can find non-GMO options. While nothing exactly mimics pasta, it is a solid alternative.
- Palmini Low Carb Pasta is another fun alternative. Made from hearts of palm, this is my go to when I need a pasta fix.
Frequently Asked Questions
Most often, a chicken alfredo recipe includes pasta, so it is not keto-friendly.
Even chicken alfredo without pasta can have excessive carbs in it. Both jarred and restaurant alfredo sauces can (but don't always) have additives that add additional carbohydrates.
This easy keto alfredo chicken bake is perfect for your ketogenic diet.
How Many Carbs are in Alfredo Sauce?
Most commercially available brands that I have found have between 3 and 5 grams of carbohydrates per serving versus 2 grams for my homemade recipe.
Yes, this recipe is great made ahead. You can make it up to a day ahead of time and bake it when you are ready to serve.
Make it Easier
Short on time? Use precooked chicken (like a rotisserie chicken from the grocery store), pre-chopped broccoli, and a keto-friendly jarred marinara.
Reheating Keto Chicken Broccoli Alfredo
If you are using my homemade alfredo sauce, you shouldn't have an issue with the sauce separating when you reheat because I use cream cheese in the sauce, which adds flavor and helps it stabilize.
You can simply heat it in the oven, toaster oven, or microwave.
Other sauces may break - meaning the fat separates from the rest of the liquid. To reheat, add a little heavy cream and heat gently in a saucepan, stirring occasionally.

This is a visual walk-through of the recipe. Please see the recipe carb below for measurements and cooking times.
This Low Carb Alfredo Chicken Bake couldn't be easier to make.
First, toss the broccoli and chicken together in a bowl.
In a separate bowl, stir together the Alfred sauce and xanthan gum. Don't have xanthan gum? No worries - it just makes the sauce a bit thicker, which I like, but the casserole works just fine without it.
Toss the alfredo sauce with the chicken and broccoli and transfer to a casserole dish.
Top with the cheeses and bake until heated through.
