Keto Chicken Fajita Casserole

This Keto Chicken Fajita Casserole is full of flavor...One of my families go-to's for weekday dinners with it's 30 minute cook time! Chicken breast, peppers, and onions are seasoned with a homemade fajita seasoning then cream cheese brings it all together.

MAKE YOUR OWN CHICKEN FAJITA SEASONING

I prefer to make my own fajita seasoning because it is easy and I always have the spices on hand.  This recipe uses salt, cumin, garlic powder, and smoked paprika.

CHEESY KETO CHICKEN FAJITAS

I love regular chicken fajitas but I think this cheesy version is out of this world.  The addition of the cream cheese really makes this a more substantial meal.  Plus, we put more shredded cheddar cheese on top!

The process of this chicken fajita casserole couldn't be easier

  • 1st we cook the peppers and onions
  • then we cook the chicken with the seasonings
  • mix it all together with the cream cheese
  • melty cheese on top and done!

KETO SIDE DISHES FOR CHICKEN FAJITAS

This dish is rich on it's own so I would choose something lighter like a side salad, Mexican cauliflower rice, or roasted broccoli.

Ingredients

  • 2 Tablespoons avocado oil (Click here for my favorite brand on Amazon)
  • 1 red pepper, sliced
  • 1 yellow pepper, sliced
  • ½ medium onion, sliced thin
  • 2 Pounds Sliced chicken breast
  • 1 ½ teaspoon Kosher salt

  • ½ teaspoon Smoked paprika
  • 1 8 ounce Cream Cheese
  • 2 Cups Shredded cheddar cheese

Instructions

  • Heat the avocado oil in a large skillet over medium-high heat.
  • Cook the vegetables until tender (should be about 8-10 minutes) then remove from the pan and set aside.
  • In the same skillet cook the chicken with the seasoning mixture on medium-high heat. Cook for 6-8 minutes or until chicken reaches an internal temperature of 165F.
  • Once your chicken is finished cooking, add all your vegetables back to the pan. Reduce the heat to medium and stir in the cream cheese until it is melted.
  • Add the shredded cheese on top and put the lid on top of the skillet so the cheese can melt.
  • Serve.

    I first made this casserole in September of 22. Since than I've made it for a neighbor who was laid up, a Sunday after church lunch, several times actually by popular teenager's demand, for our kids and grandkids, and made a batch to freeze for lunches. As I prepare to make another casserole I just wanted to let you know how delicious, quick and easy it is to make!

    I am always looking for kid friendly keto main dishes because I do not want to make separate meals and then I just add nonketo side dishes for the rest of the family. I made this tonight and it was DELICIOUS. Even the kids ate it up with compliments. To cut down on some of the calories I did use only 6 ounces of cream cheese and a 1.5 cups of cheese and it was still very creamy. This will become part of my regular dinner rotation.

    Trying to read and understand Keto before starting Keto. What is the serving size of the dish? Or do you not have serving sizes on Keto. Thanks

    Can I ask what you would recommend serving this alongside? Staying true to no carbs of course. 🙂

    Hi i love your recipes i am wanting to start keto to loose weight and be healthy again. How do i start out? Some seasonings i cant have and have to substitute and cant have dairy but can have goats milk when calls for milk. Can you help me ?

      Hi Susan, the best thing you can do is keep it simple. If you cannot have dairy, can you have coconut milk? You could try to replace some of the dairy with that. If there are certain seasonings you can't have, I would just leave them out. They best thing to do is to eat meat and veggies!

    Just made the Chicken Fajita Casserole...of course, I am a Klutz in the kitchen, so it took me 90 minutes to make a 30 minute recipe, even after I cut up all the veggies this morning. I didn't have cheddar cheese so I substituted Mexican Blend and you can't have fajitas without sour cream and a side of guacamole. DELICIOUS.... I will make this again...

    Thanks for the recipes.. wishing you the best in your Keto journey.

    My family has at least 1-2 Mexican meals each week. I was just searching around for some new recipes to mix up our routine. Glad I stumbled upon your site and this recipe. I'll be trying it out next week with the family. Looking forward to seeing how it goes. Thank you for sharing!
