Easy Cheesy Keto Chicken Enchilada Casserole Recipe FAQs
What type of red enchilada sauce should I use for a keto diet?
Absolutely, it’s best to opt for a low-carb, sugar-free enchilada sauce to keep this dish keto-friendly. Look for sauces that have 1-2 grams of carbs per serving at the grocery store. You can also try making your own sauce to control the ingredients and flavor completely.
How can I store leftovers of my casserole?
Very! Allow the casserole to cool completely before placing it in an airtight container. It’ll last in the refrigerator for about 3 to 4 days. When you’re ready to enjoy it again, simply reheat individual portions in the microwave or oven until warmed through.

What can I do if my casserole is too watery?
If your casserole turns out watery, don’t worry! Next time, consider using less enchilada sauce or draining excess liquid from the ingredients before mixing. You can also add in a thickener like cream cheese, which will help absorb excess moisture and add creaminess.
Are there any allergy considerations with this recipe?
For sure! If you or someone in your family has dairy allergies, you can substitute cream cheese with a dairy-free cream cheese alternative. Be cautious of any additional toppings as well; avocado and cilantro are generally safe but be sure to check for any individual sensitivities.
