How to Make Low Carb Chicken Broccoli Casserole

Start by preparing the oven and preheating it to 375°F.

Meanwhile, using a stove, put water to boil, and cook broccoli florets in. After five minutes, drain the broccoli using a colander.

Prepare the chicken by cutting it into bite-sized chunks. You can use rotisserie chicken too. Make sure to remove all the bones.

In a small casserole dish mix, mix the chunks of chicken with the previously cooked broccoli.

Using the sauce, coat the cooked broccoli and chicken with it and make sure to mix it well. You can add a table spoon of full fat cream cheese too. If the consistency is too thick, you might add a little bit of chicken broth in.

Finally, sprinkle over some grated cheese on the coated mixture and bake it for around 7 to 10 minutes. Serve and enjoy!

Cooking Tips

Can I use frozen broccoli for this recipe?

Yes, you can use frozen broccoli florets for the Keto Broccoli Chicken Casserole recipe. Just ensure to thaw it properly and drain any excess water before cooking. Frozen broccoli might not need to be boiled as long as fresh broccoli since it’s typically blanched before freezing, so adjust the cooking time accordingly. This can help maintain its texture and prevent it from becoming too soft in the casserole.

How to freeze broccoli chicken casserole

To freeze broccoli chicken casserole, first let it cool to room temperature. Then, wrap the casserole dish tightly with aluminum foil or plastic wrap, or transfer the casserole into an airtight container. Label it with the date and freeze. It can typically be stored in the freezer for up to 3 months. When ready to eat, you can thaw it in the refrigerator overnight and reheat it in the oven or microwave.

How to reheat chicken broccoli casserole

To reheat chicken broccoli casserole, warm it in the oven at 350°F for about 7-12 minutes or until heated through. You can also microwave it in short intervals, stirring occasionally to ensure even heating.
