| Classic Fajitas But in a Creamy Cheesy Casserole!

Classic stovetop fajitas turned into a delicious casserole that your whole family will love. Delicious sour cream and cheese are blended with taco seasoning, sauteed chicken and veggies for the perfect dinner. This recipe is an almost weekly occurrence in our household! LOL

| Easy to Make Meal Prep Recipe or Weeknight Dinner

This is a perfect weeknight meal to make (weekends are good too! LOL). I think it’s total comfort food. Comfort food is great during a crazy weeknight don’t you think? ? I know after a long day of working I want something simple, satisfying and EASY to make – this fajita bake fits the bill!

| One Pan Skillet Meal From Stovetop to Oven

While you can use any oven proof skillet, I love to use my cast iron skillet for this recipe. The more seasoned a cast iron skillet is the more flavoring it imparts!

By sauteing the chicken and peppers with the taco seasoning before baking you create a ton of flavor from the browning, carmelizing and blending of all the flavors. Mix in the remaining ingredients and then pop in the oven just until the cheese is bubbly.

Keto Chicken Fajitas

With healthy fats and low carb vegetables, chicken fajitas bake is a great option if you are following a ketogenic diet. If needed, you can increase healthy fat content by adding avocado or cooking in additional olive oil. You can also substitute chicken thighs for chicken breasts.

The great thing about this recipe is that it is completely flexible to your day’s dietary requirements. If you are over on your protein for the day you can reduce the amount of chicken in your serving, if you are over on your carb requirements, you can use less onion.

, or you can use like I did in the photos – my kids love it for some reason! ? chef’s knife

cutting board

measuring spoons


1 tablespoon olive oil

6 boneless skinless chicken thighs or breasts, 1″ to 2″ pieces

4 bell peppers, sliced (vary the colors to make it pretty! I used green, yellow, red, and orange)

small onion, thinly sliced

1 recipe Copycat Taco Seasoning Mix Recipe (or 1 taco seasoning packet, fajita seasoning is fine too)

(or 1 taco seasoning packet, fajita seasoning is fine too) 1 cup sour cream

4 oz cream cheese, softened

2 cups cheddar cheese, grated

optional: sour cream, avocado slices or guacamole, cilantro, and salsa. Don’t forget hot sauce for the spicy lovers! ?

Try our Homemade Guacamole recipe! You’ll love how fresh and easy it is. No need to buy mushy store-bought guacamole anymore.

How To Make Keto Chicken Fajita Casserole

Preheat oven to 350 degrees F. In an oven proof skillet, over medium heat, saute the chicken in olive oil until the chicken is done. Remove from skillet and set aside. (see image #1) Add onions and peppers and saute until tender, (approximately 3 to 5 minutes depending upon your preference). (see image #2) Add chicken back to the pan and stir in the taco seasoning, sour cream, and cream cheese. Mix well. (see image #3) Sprinkle the top with cheese and bake in the oven for 15 to 20 minutes or until cheese is bubbly. (see image #4)

Tip: the safe cooking temperature of chicken is 165º

Serve and enjoy! Really good topped with avocado, guacamole, sour cream, or salsa. Yum

Helpful Tips

Use boneless chicken thighs or breasts that have been cut into uniform sizes (approx 1″ to 2″ in size, or you can do 1.2″ strips if you prefer)

Onions cook slower than peppers so I often add them a few minutes before I add the peppers. This is strictly personal preference of course.

You can cook the onions and peppers to your desired tenderness. Some people love them crisp-tender, some love them completely soft.

Consider making our homemade taco seasoning instead of buying a store-bought packet! This isn’t just a plug for you to check out the recipe, it’s highly rated, very good, healthy, and SUPER EASY. I made the recipe because I was tired of serving my family a packet of taco seasoning that I couldn’t pronounce all the ingredients (i.e chemicals)

Cook the chicken to 165º – the safe internal cooking temperature.

Since most of the recipe is cooked, you only need to bake the casserole to get the cheese bubbly and heat the inside. No more no less. ? Technically you don’t even have to bake this casserole, but you won’t have that nice ooey gooey melted cheese on top! There is just something about baking all the ingredients together – all the flavors blend together and make a whole casserole of tasty goodness. LOL

If you don’t have an oven proof skillet just cook chicken, peppers, and onion according to the recipe. Stir in the cream cheese and sour cream. Put the mixture into a casserole dish then top with cheese and bake.

What To Serve With Baked Chicken Fajitas

There are a lot of options on what to serve with chicken fajitas but overall, I like to round out the meal with a simple salad of shredded iceberg lettuce, diced tomato, and green onion.

Instead of using a typical salad dressing I just top the salad with a dollop of sour cream and salsa and toss it together, making an easy tasty salad dressing.

Sliced avocados make a perfect topping for this casserole, but if you want to take it up a notch I HIGHLY recommend my Homemade Guacamole!! It’s so dang good. My husband always said he hated guacamole, but it turns out he had only tried the mushy store-bought guacamole. This is NOT the same thing in my book. Guacamole is best with fresh avocado, tomato, onion, jalapeno, lime, and salt. I leave it chunky.

“I love the warm flavorful, slightly spicy, fajita casserole balanced with the cold crisp fresh taste of a simple salad. ”

If you are not following a low carb or ketogenic diet then serving with fajita tortillas on the side make a delicious way to serve up your chicken fajita bake.

What Temperature Should Chicken Be Cooked To?

The USDA recommends that chicken should be cooked to 165º degrees. I always check the temperature of my chicken with an instant read thermometer. Here is a link to their Safe Minimum Internal Temperature Chart.

What Toppings Go On Chicken Fajitas?

Typically people top their fajitas with shredded cheddar cheese, sour cream, salsa or taco sauce, and avocado slices or guacamole. Of course, this is all a personal preference!

I also love to top with shredded lettuce, tomatoes, and green onion too! Because this recipe is in a casserole form and the cheese has been mixed in, you probably don’t need to top with more cheese, but if you’re a cheese lover go ahead.

Are Chicken Fajitas Healthy For You?

Chicken fajitas are very healthy, yes. With plenty of nutrients, healthy fat, protein, and fiber you will feel satisfied long after your meal is over.

Amazingly, each serving of this chicken fajita bake has over 100% of your day’s vitamin C, 35% Vitamin A, 30% zinc, 23% calcium, and is loaded with Vitamin B’s! 48% Vitamin B12, 45% Vitamin B6, 44% Vitamin B3, 41% Riboflavin B2.

Where are all these vitamins coming from? Well, of course the fats are coming from the chicken, olive oil, cheese, and sour cream. The calcium is mainly coming from the cheese and sour cream, but the bulk of the remaining B’s, Vitamin A , and Zinc, are coming from the bell peppers.

Did you know that the longer a pepper remains on the vine before picking, the more nutrients it contains? Yep. I grow a lot of peppers in my garden and I’ve often let them sit on the vine. Peppers first ripen to green (this is when they are most commonly picked), then they turn yellow, orange, and then red. Out of curiosity I did some research and found that a red bell is the most nutrient-packed of all the bell peppers. ?

Here’s a super interesting article about peppers from WebMD:

Pepper Power: Nutrition and Other Benefits

Can I Freeze Fajita Chicken Fajita Bake?

Yes, definitely! That’s one of the best things about this casserole. You can portion out meals, freeze in airtight containers for up to 3 months. Thaw in the refrigerator before reheating.

Chicken Fajita Bake makes amazing leftovers for lunch!! So much flavor and a great change-up from soup and sandwiches.

How Do You Cut Chicken Breast for Chicken Fajitas?

For traditional fajitas, cut chicken breast into thin 1/2″ strips sliced horizontally, cutting against the grain. This recipe calls for smaller bite size pieces, but you can really cut them to the size that you prefer most.

Keep in mind that the smaller the pieces the quicker they will cook so you may need to shorten your cooking time as recommended by the recipe instructions.

Do I Have To Use A Cast Iron Skillet?

No, you do not have to use a cast iron skillet. Any ovenproof skillet will work. If you don’t have an oven-proof skillet no problem! You can simply mix in the cheeses in your pan and place in a casserole dish.
