Types Of Chicken For a Chicken Alfredo Bake
Any grilled chicken will work well for this recipe. If you are a fan of bulk cooking chicken, add some shredded in. Use up a leftover rotisserie chicken, or buy pre-cooked strips. Any type of chicken that doesn't have a breading on it will work great for this recipe.
Sometimes I buy a large package of chicken at the store and cook it all up at once, then freeze servings in freezer bags. That way when I want to make a casserole or soup, it is one less step in the recipe. Works wonderfully!
Just make sure that any chicken you use, isn't overly seasoned already. That will add flavors to the recipe, so you want more a bland chicken, as it will take on characteristics of the sauce in the casserole.
Can I Add Other Vegetables Into the Alfredo Bake
Don't like Brussels sprouts? Want to switch in a different veggie?
Go for it! If you want to toss in some other vegetables, go for it. You can use cauliflower, green beans, or any other veggie your family enjoys. Sometimes I raid my fridge to see what I have on hand. If you are using a vegetable that is not shredded like the Brussels sprouts or cooks quickly like spinach you should steam it first. The steamable microwave bags of broccoli and cauliflower are great for making casserole prep easier.
But, you can indeed add to the recipe to add more dimensions of flavor if you prefer. This chicken bake is very versatile.

How To Make Chicken Alfredo Bake
Start by preheating the oven. Once that is done put your shredded Brussels sprouts and diced chicken in a greased casserole pan.
Then start by making your sauce on the stove top. Combine your ingredients and simmer for a few minutes to help thicken the sauce. During this make sure to salt and pepper to taste. Once sauce is ready and nice and thick, toss in your parmesan cheese and give a good stir.
Pour the sauce over the chicken and sprouts, and bake until browned and nice and bubbly.
As you can see this recipe is absolutely simple to make! It will be an instant go-to recipe for those weeknights when you are craving something comforting!
Sides to Pair With Your Chicken Alfredo
- Steamed or Roasted Vegetables
- Caesar Salad
- Low Carb Braided Garlic Breadsticks
- Almond Flour Keto Biscuits
Add a side or skip it, this is entirely up to you! We generally eat the casserole with a salad on the side, or if I know guests are coming over, we might serve with a few sides, so they have options.
How To Store Leftover Chicken Alfredo Bake
Place any leftover chicken and Brussel sprouts bake in an airtight container and store in the fridge for up to 3 days. After that, you will want to toss out any leftover casserole.
Can You Freeze Low Carb Alfredo?
This is a yes and no answer. Yes, you can freeze your chicken alfredo casserole, but it could change in texture when you go to reheat it. I say this because a lot of times milk-based white sauces can separate when they are frozen, so when you go to reheat it won't be that silky smooth texture like if you cooked it that night.
The casserole will taste the same; it just won't have as creamy of a sauce if you freeze it first.
Best Way To Reheat Your Chicken Alfredo Bake
Feel free to use the microwave or even oven to reheat your chicken alfredo bake. If you choose to reheat in the oven, just wrap your pan in aluminum foil. This will help prevent your sauce from drying up as you go to reheat. Just heat in the oven at 350 degrees until the bake is warmed all the way through.
If you go the microwave route, just reheat until warmed through. If the sauce is too thick, add a tiny splash of milk, stir and then warm up a little bit more to gain back that creamy texture. You can do the same for the oven route as well.
