The weather is getting colder and that means casserole time for me. I wanted to make a new recipe for the blog so I made this super duper easy keto Mexican chicken casserole.
OMG just looking at these pictures makes me wished I had some leftovers. It was rich, cheesy and full of chicken so it’s filling too. Perfect keto comfort food.

Only 7 Casserole Ingredients
The ingredients I used for this casserole were cooked chicken breast, cream cheese, cauliflower rice, salsa, Mexican cheese, chili powder and cumin.
This is definitely a leftover rotisserie chicken recipe. It will only take a few minutes to mix everything then all you have to do is bake it!
TIP: I often buy 2 rotisserie chickens when I go to Costco because they are inexpensive and relatively big. I take all the meat off the chickens and portion 1 cup servings into ziplock bags. Then I freeze them for dishes like this. Save the bones to make chicken broth!

Let’s Make The Keto Mexican Chicken Casserole
- Add the cream cheese and salsa to bowl and microwave for a minute or two to soften the cream cheese. Add the spices and mix together well.
- In a large bowl mix the cream cheese mixture, chicken and half of the cheese. Spoon into a sprayed casserole dish.
- Top the casserole with the remaining cheese and bake for 30 minutes until browned on top.

I have quite a few recipes on this blog that uses rotisserie chicken. You can use it to stuff peppers, in low carb soups, buffalo chicken dips, casseroles and even chicken salads.
Recipe Tips & Notes
- I use chunky salsa from Aldi which had a lot of carbs and accounts for most of the carbs in this recipe. If you have a lower carb brand go ahead and use that. This is the main source of Mexican flavors. I have an awesome keto salsa recipe but I didn’t want you to have to make that first so I used jarred salsa.
- I bought my Mexican cheese blend from Costco and it was delicious and low carb. Again try to find the lowest brand you can or grate your own cheddar and Monterey Jack cheeses.
- This is the perfect recipe to freeze for a low carb lunch. Just portion out the leftovers and place in a freezer container. Microwave for a few minutes to reheat.

Well I must say this was one of my favorite recipes lately. It was so easy and comforting. I hope you enjoy it as well.
