Low Carb Alfredo Chicken Casserole Ingredients
- Spaghetti Squash– You will only need one medium sized spaghetti squash.
- Shredded/Diced Chicken– There are multiple various you can use. You can purchase rotisserie style chicken or even cook your own prior to starting this recipe. We have opted for the rotisserie chicken because the work is already done for us and it’s super delicious.
- Parmesan Cheese– If you’re on a budget you may want to just use the parmesan cheese that comes in a can, but I highly suggest shredding your own or even buying the pre-shredded parmesan cheese that you can find in the deli section of your grocery store.
- Mozzarella Cheese– Here you can purchase the pre-shredded as well. However, I prefer to shred it myself because it melts better.
- Alfredo Sauce– Follow my recipe for Low Carb Alfredo Sauce. This only takes 10 minutes to make and you will use the entire batch. Easy peasy.
- Broccoli– For this recipe, we are using one 1lb bag of broccoli. The broccoli we’re using can be steamed in the microwave. If you choose to use fresh broccoli make sure you cook before adding to the casserole and note that the entire cook time for this meal will be extended.
- Garlic Powder– For just a bit of yummy garlic taste.
- Onion Powder– Adds a bit of the onion flavor without the hassle of sautéing.
- Chili Flakes– Optional, but adds a nice bit of heat.
- Salt and Pepper– A must for all savory dishes.
Assembling Our Low Carb Alfredo Chicken Casserole
First things first: cook your spaghetti squash. Here we are using our pressure cooker How To Cook Spaghetti Squash- In The Instant Pot. If you do not have a pressure cooker/instant pot you can roast your spaghetti squash in the oven at 400°F for 35-40 minutes.
Once the spaghetti squash is in the pressure cooker, start cooking your broccoli. If you are using a steamer bag, just place in the microwave and follow instructions on the bag.
While our spaghetti squash and broccoli are doing their thing we’ll make our Low Carb Alfredo Sauce.
At this time our spaghetti squash, broccoli and alfredo sauce should all be done. Now you will preheat your oven to 450°F. While the oven is preheating we’ll add all the ingredients together.
To a large mixing bowl add your steamed broccoli. I personally like to use my meat chopper to break the florets up a bit so they are more bite sized, but you can opt to chop with a knife or leave as is. Next add the spaghetti squash, garlic powder, onion powder, salt , pepper and chili flakes.
Our next step is to add the chopped/diced chicken. Once our chicken has been added to the bowl, add the Low Carb Alfredo Sauce and half of the parmesan cheese and half of the mozzarella cheese.
You’ll want to mix everything up really well.
Now that our delicious Low Carb Alfredo Chicken is mixed super well, we’ll add everything to a lightly greased 9×13″ baking dish and then top with the remaining parmesan and mozzarella cheese.
You’re almost there! Now just place in the oven for 20 minutes or until nice and golden brown. If after 20 minutes the cheese hasn’t browned, then you can put under the broiler for 5 minutes. Just be careful not to burn it.
Once cooked, allow the casserole to sit for 5-8 minutes and then dig in! You can top with more cheese or eat as is.
