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!

In a large bowl mix the cream cheese mixture, chicken and half of the cheese. Spoon into a sprayed casserole dish.

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.
