No, this recipe takes classic enchiladas and puts a keto spin on it to make a casserole. It has all the flavors of a chicken enchilada you love, without the extra carbs that a tortilla would add!

What Type of Chicken should I use?

I prefer to use shredded chicken breasts made in the crock-pot because I’m not too fond of dark meat, but you can also use chicken thighs or rotisserie chicken if you prefer. Use your favorite cut of chicken!

Can I use Canned Enchilada Sauce?

I personally would not recommend using canned enchilada sauce as it contains corn starch and sugar. It is also much higher in carbs than the easy homemade version in the recipe card below. However, if you are low carb and not following a keto diet, it might fit into your macros.

Toppings for Keto Chicken Enchilada Casserole

This recipe is so versatile you can top it with your favorite Mexican toppings. Here are some of the most popular in my house, diced onion for a bit of crunch, jalapenos peppers to add some spice, sour cream to cool down the heat and add an extra creamy texture, lime for a little bit of tang, or even avocado slices to add extra fat!

Can I Make This Ahead of Time?

Yes! Meal prep is a large part of the keto diet, and casseroles are one of the easiest meals for meal prep! To make keto chicken enchilada casserole, ahead of time combine the ingredients for the enchilada sauce, mix in the chicken and cheese, layer in the baking dish. Reserve the cheese that will be sprinkled over the top until after baking to have a better texture. Place the prepared casserole in the fridge or freezer, depending on when you plan to bake it. When you are ready to bake, take it out of the oven, sprinkle the cheese on top, and pop it in the oven. It make take a little longer to bake since it is cold from the fridge.

Can you Freeze Keto Chicken Enchilada Casserole?

To freeze, prepare the casserole as the instructions describe but do not add the extra cheese over the top. Frozen cheese can have an odd texture that will throw the entire dish off. Once you have layered the casserole in the pan, wrap with saran wrap first, then use aluminum foil to seal the entire pan. Make sure to crimp the edges making the wrap as tight as possible, so it does not get freezer burned. This dish can last for 3 months in the freezer.

How to Store leftovers:

Place the leftover enchilada casserole in an airtight container in the fridge for up to 3-4 days. If you do not plan on eating them within this time period, you can also place them in a freezer-friendly airtight container and store them for up to 3 months.

Best Way to Reheat:

If your casserole has been frozen, remove it from the freezer the night before baking and place it in the fridge overnight. Once it has thawed, sprinkle the cheese mixture over the top and bake for the time designated in the recipe card.

If you have already baked your casserole and are rewarming leftovers, place them in the microwave until warmed or place in the oven until the desired temperature has been reached.
