Keto Mexican Chicken Casserole Recipe FAQs
How do I choose ripe ingredients for my keto Mexican chicken casserole?
Absolutely! When selecting chicken, look for fresh, pink meat without any dark spots or unpleasant odors. If you're opting for cauliflower rice, choose cauliflower heads that are firm and free from blemishes or dark spots. For salsa, opt for low-carb varieties, checking the label for added sugars.
What’s the best way to store leftover keto Mexican chicken casserole?
Very! After allowing the casserole to cool completely, transfer it to an airtight container and store it in the refrigerator for up to 3 days. Keeping it sealed helps maintain its flavors and prevents it from absorbing any other fridge odors.

What can I do if my casserole turns out too watery?
Oh no! If you find your casserole is too watery, it might be due to excess moisture from the cauliflower rice.

You can also gently sauté fresh cauliflower rice in a pan for a few minutes to cook off some of the moisture ahead of time.
