Reduce the heat to medium, and then add the heavy cream to the skillet. Make sure that you are stirring the entire time until the mixture has reduced by half. It should also be thick and creamy. Set it aside.

Variations

Keep in mind that any variations that you add or do will change the calorie count and the net carbs.

Extra Creamy – If you want to add cream cheese to the mixture, it compliments the green chiles and the rest of the ingredients really well.

Chicken – Change the type of cooked chickenUsing chicken leftovers is perfect for this dish. You can use chicken breast, rotisserie chicken, chicken thighs, and any leftovers from chicken recipes that you’ve cooked. Just be sure that you remove any bones, etc. – prior to adding.

Cauliflower Rice – To give this a hearty texture, you can add cauliflower rice to this cheesy chicken dish. Just pour it in, and let the oven cook it up! This is based on my Green Chile Cauliflower Casserole!

Toppings – Fresh cilantro and an extra cup of cheese on top sound divine! If you want to add some spice, sprinkle a bit of cayenne pepper on top.

Beans – If you aren’t doing keto you can try adding a can of black beans really helps with the Southwestern flavors!

Enchiladas – Take the filling and use it to fill low carb tortillas. Place them back in the casserole dish, top with Keto Enchilada Sauce, and you’ll have green chile chicken enchiladas in no time!

Common Questions

Can I add low carb tortillas?

You can, as I mentioned above and as I do in my Keto Enchilada Casserole but an even better option might be to add the mixture to the tortillas after it has cooked! That way, some can enjoy it just like it is, while others can use the individual servings to pair with a soft tortilla base.

What pairs well with this delicious dinner?

For those eating low carb, a nice and easy option would be steamed veggies. For kids or adults who don’t live the keto lifestyle, having an option for cooked Spanish rice is perfect, too.

What are good toppings to add to this chicken enchilada casserole?

I love pouring hot sauce on top! Also, cooking and adding a fried egg on top is a great way to boost the protein! Of course, any leftover green chilis can be placed on top as well.

How do I store leftovers? 

Let the casserole cool completely, and then store it in the fridge in an airtight container. You need to have a locking lid so that it stays fresh. This should keep it good for 2-3 days. 

To reheat, warm it back up in the oven until it is heated all the way, or add a portion to a microwave-safe bowl or plate and heat that way.
