There are plenty of recipes for chicken fajitas, but not all of them are equal. We’ve done the work for you and compiled a list of the best chicken fajita recipe ideas for keto diets.
Top Chicken Fajita Recipe Ideas for Keto
Each of these recipes contains healthy ingredients filled with protein, fats, and dietary fibers, keeping carbs to a minimum.
1. Sheet Pan Chicken Fajitas – Best Chicken Fajitas Recipe
Starting off our list is one of our recipes for sheet pan chicken fajitas. It’s easy to make, tasty, healthy, and requires few ingredients.
This recipe is perfect for those busy weeknights when you don’t have much time to cook but still want to enjoy a healthy and delicious meal.
Plus, this recipe is not only keto-friendly but also gluten-free, grain-free, dairy-free, and paleo-friendly.
Ingredients:
- Boneless, skinless chicken thighs
- Limes
- Olive oil
- Kosher salt
- Chili powder
- Garlic powder
- Ground cumin
- Cayenne pepper
- Bell peppers
- White onions
- Sour cream
- Avocados
All ingredients are perfect for a keto diet, so there’s no need to substitute them. This dish also happens to be ideal if you happen to be on the Whole30 diet, as long as you skip the sour cream.
To make it even more flavorful, prepare a bowl of keto cheese sauce for dipping or topping your fajitas with shredded cheddar cheese.
2. Air Fryer Chicken Fajitas Recipe
Traditional fajita recipes usually include grilled or broiled meat. But you can still make it delicious in the air fryer.
This recipe from Little Sunny Kitchen is healthy, keto-friendly, and super easy to make.
Plus, it’s a great option if you’re looking for a quick and easy weeknight dinner idea.
Ingredients:
- Boneless and skinless chicken breasts
- Red, yellow, and green bell peppers
- Fajita seasoning
- Vegetable oil
- Red onions
The ingredients are pretty standard. But the show’s real star is the air fryer since it cuts down on the cooking time and calories while still giving you that perfect deep-fried taste.
A Mexican dish deserves a Mexican side dish, so we recommend pairing these fajitas with homemade keto cheese chips and guacamole.
3. Easy Chicken Fajitas Recipe
Without a doubt, a skillet improves the taste of food. It might not be the first kitchen appliance that pops to mind, but it’s practical for quickly whipping up fajitas when you have a craving.
This dish from Stockpiling Moms is delicious and easy to make, as well as healthy and keto-friendly. And it’s quite juicy compared to other recipes.
Ingredients:
- Chicken strips
- Sliced red bell pepper
- Sliced yellow bell pepper
- Olive oil divided
- Chicken broth
- Dried oregano
- Garlic powder
- Ground cumin
- Chili powder
- Onions
- Salt
- Lettuce wraps (optional)
- Flour tortillas (to be replaced)
Unfortunately, the original recipe isn’t entirely keto since it asks for regular flour tortillas. But you can replace them with homemade almond flour tortillas.
4. Crockpot Chicken Fajitas Recipe
Another interesting way to cook chicken fajitas is by using a crockpot – perfect if you like your chicken extra-tender.
We included this recipe from That Low Carb Life since it’s keto, gluten-free, and easy to prepare.
Since a crockpot cooks food slowly, you will have to wait a bit longer for the fajitas (3 to 6 hours), but at least you won’t have to babysit them.
Ingredients:
- Boneless, skinless chicken breasts
- Salsa (jarred or homemade)
- Bell peppers (any color)
- Cream cheese
- Minced garlic
- Black pepper
- Paprika
- Cumin
- Onions
- Limes
- Salt
We suggest making your own salsa since store-bought items are usually packed with sugar.
Also, try serving the fajitas with garlic-flavored cauliflower rice since it tastes amazing and is low on carbs.
5. Recipe for Chicken Fajitas in Crockpot
Crockpots and slow cookers have one thing in common: cooking meat so tender that you’ll love it more for the mouthfeel than the actual taste.
And this is the basis of this recipe from The Protein Chef.
Ingredients:
- Chicken breast
- Fajita vegetables (frozen or fresh bell peppers and onions)
- Fajita or taco seasoning mix
- Minced garlic
- Lime juice
- Tomatoes
- Honey (to be replaced)
Since you’re using a slow cooker or a crockpot, it doesn’t matter if the vegetables are pre-cooked, fresh, or frozen since they end up perfectly cooked anyway.
But you should ditch the honey and replace it with erythritol or another keto-friendly sweetener to make the meal entirely keto.
We also suggest serving this meal with cauliflower rice.
6. Oven Fajita Chicken Recipe
In case you didn’t know, chicken fajitas can also be made into a casserole, not just a filling for tacos.
To do so, you must bake the fajitas in a way that prevents them from going dry.
The folks over at Seeking Good Eats have come up with a great solution: smothering those fajitas in so much cheese that it should be illegal.
Ingredients:
- Chicken thighs
- Onions
- Olive oil
- Sour cream
- Cream cheese
- Fajita seasoning
- Cheddar cheese
For the first couple of steps, the recipe is pretty standard. But, in the last part, you must add cheese and cream on top of the cooked chicken and sauteed vegetables before throwing the whole skillet in the oven.
It’s the perfect skillet dinner for anyone with a soft spot for cheesy delights.
And it’s one of those keto chicken casseroles that remind you that you can still eat tasty things on a diet.
7. Best Fajita Chicken Recipe
If you liked the cheesy recipe mentioned earlier, you’ll love the next one from Real Balanced. It’s similar but a lot cheesier and spicier.
Ingredients:
- Boneless, skinless chicken breasts
- Salt
- Cumin
- Pepper
- Paprika
- Avocado oil
- Warm water
- Chili powder
- Garlic powder
- Onion powder
- Cream cheese
- Mini sweet peppers
- Ground cayenne pepper
- Shredded mozzarella cheese
The mix of cream cheese and mozzarella gives this recipe its distinct flavor.
Also, we love how the recipe suggests marinating the chicken in the seasoning instead of just rubbing it a little to help the meat retain its flavor.
8. Easy Fajita Chicken Recipe
The entire gimmick of keto is that you’re supposed to eat fewer carbs while compensating with extra fat and protein.
So it’s only natural to include a recipe for low-carb chicken fajitas. This one from Life Made Keto uses low-carb tortillas.
Ingredients:
- Chicken thighs
- Salt
- Cumin
- Olive oil
- Lime juice
- Red onions
- Chili powder
- Black pepper
- Garlic powder
- Onion powder
- Butter divided
- Smoked paprika
- Chopped cilantro
- Bell peppers (any color)
- Ground mustard or Dijon mustard
We love how the recipe focuses on teaching you how to make fajita seasoning mix. So you won’t have to rely on store-bought products likely loaded with sugar or other unhealthy ingredients.
9. Classic Keto Chicken Fajitas
Many people prefer simple recipes with pre-made ingredients since there are fewer steps and less room for mistakes.
This recipe from Fit to Serve Group heavily relies on store-bought mixes, and it’s a pretty solid choice if you want something quick and easy.
Ingredients:
- Chicken breast
- Onions
- Avocado oil
- Minced garlic
- Sliced red, green, and yellow or orange bell peppers
As you can see, the ingredients are pretty standard. And the only way to make the dish stand out is by pairing it with your favorite fajita seasoning mix.
10. Easy Chicken Fajita Recipe with Fajita Seasoning
If you agree that the seasoning used in making fajitas separates the good ones from the great ones, then you’ll want to try this recipe from McCormick.
While most recipes would have you make your seasoning mix, this one uses a pre-made mix from McCormick to cut down on the cooking time.
It’s safe to say that the entire recipe revolves around using this particular seasoning.
Ingredients:
- Boneless, skinless chicken breasts
- McCormick Fajita Seasoning Mix
- Bell peppers (any color)
- Vegetable oil, divided
- Sliced onions
- Water
- Flour tortillas (to be replaced)
11. Recipe for Chicken Fajitas in the Oven
Don’t you just love it when a recipe asks that you throw some ingredients on a sheet pan, leave it in the oven for a while, and all o a sudden you have a delicious meal?
If the answer is yes, you’ll love this keto sheet pan chicken fajita recipe that we found on Mary’s Whole Life since it’s just chicken, seasoning, and vegetables, without any sauces or other things that could potentially complicate the dish.
Ingredients:
- Chicken breasts
- Onions
- Avocado oil
- Red bell pepper
- Orange bell pepper
- Green bell pepper
Chicken breasts tend to dry out quickly, especially when cooked on a sheet pan without anything to cover it, so if you want your fajitas to be juicy and moist, try replacing them with chicken thighs instead.
They stay juicy, but they also have more fat (especially if you leave the skin on), which is a big plus considering that you want your diet to be high both in protein and fat.
12. Best Recipe for Chicken Fajitas
The cast-iron skillet was introduced somewhere during the 19th century, and whoever brought it into existence deserves a medal.
Sure, you can technically cook anything in any kind of pan, but a cast-iron skillet makes everything taste better.
This recipe from Cast Iron Keto is no different. It uses a cast-iron skillet to cook chicken, peppers, and onions until they’re perfectly charred on the outside while remaining juicy and moist on the inside.
Ingredients:
- Boneless, skinless chicken breasts
- Sliced orange, yellow, green, and red bell peppers
- Sliced jalapeño or serrano
- Taco seasoning
- Roma tomatoes
- Sliced onions
- Avocado oil
- Sea salt
- Butter
Besides the amazing taste, this dish is also an absolute explosion of colors thanks to all the different kinds of peppers used, so consider this recipe whenever you have guests and want to serve them something eyecatching.
Speaking of serving, if you want something that would go well with this dish, we suggest a side of BBQ mushrooms to take things up a notch.
13. Recipe for Chicken Fajitas on the Grill
It’s not uncommon for fans of Mexican foods to also like Texan foods and vice-versa, but what if we told you that you could make chicken fajitas in a way that brings the best of both worlds?
Allow us to present this amazing recipe for Tex-Mex chicken fajitas that we found on Life Made Sweeter.
Ingredients:
- Pounded chicken breasts
- Sliced bell peppers (any color)
- Sliced red onions
- Smoked paprika
- Unsalted butter
- Garlic powder
- Chili powder
- Lime juice
- Olive oil
- Cumin
- Salt
This recipe’s Tex-Mex taste is the homemade seasoning made using chili powder, cumin, garlic powder, smoked paprika, and salt.
Make sure that when you read the full recipe, you pay close attention to the amounts given for each ingredient. Otherwise, your fajita will end up tasting pretty generic.
14. Authentic Fajitas Recipe Chicken
If you’re not much of a fan of the whole Tex-Mex blend and a firm believer that regional recipes need to stay true to their roots, we have some good news for you: this recipe is as authentic as they come.
The Bossy Kitchen walks us through making chicken fajitas the Mexican way, and while it might not be the quickest recipe on our list, it’s one of the tastiest.
Ingredients:
- Boneless, skinless chicken breasts
- 3 bell peppers (one of each color)
- Ground cinnamon
- Granulated sugar
- Cayenne pepper
- Dried oregano
- Sliced onions
- Vegetable oil
- Lime juice
- Salt
This fajitas recipe is versatile since you can use the same steps and ingredients (except the meat) to make any fajitas you want, including beef or shrimp.
Just remember to eat it fresh alongside a big serving of guacamole, cauliflower rice, queso sauce, or pico de gallo if you’re looking for something more colorful.
15. The Best Chicken Fajita Recipe
Many emphases are put on what ingredients you use when preparing a meal or what type of cooking method you’ll be using (e.g., skillet, Crockpot, etc.).
However, not everyone understands that sometimes the key to a delicious dish starts way before you start cooking.
For example, this recipe that we stumbled upon on Tasty Low Carb requires that the chicken breasts be marinated for at least 30 minutes before cooking.
Ingredients:
- Chicken breasts
- Cilantro
- Sea salt
- Olive oil
- Chili powder
- White onions
- Garlic powder
- Cumin powder
- Smoked paprika
- Lime juice (fresh)
- Ancho chili powder
- Olive oil (extra virgin)
- Bell peppers (red, orange, and yellow)
While reading up on this recipe, you’ll probably believe that the cast-iron skillet is the hero of the story as far as kitchen utensils are concerned, but you’d be wrong.
In truth, your most important piece of equipment will be a typical plastic zip lock bag that you’ll use to marinade the chicken since this is when the meat draws out all of the flavors.
Once the meat is cooked, make sure to wrap the fajitas in a low-carb tortilla, or you can skip the carbs altogether and just enjoy the chicken and veggies as is.
16. Copycat Chili’s Fajita Recipe Chicken
Chilli’s chicken fajitas are very popular all around the world, so it’s no wonder that at least one food website came up with a copycat recipe that allows you to make this dish at home.
This copycat recipe is all courtesy of Recipes.net, and it’s pretty straightforward to follow.
The best part is that, while the original Chilli’s chicken fajitas aren’t keto, we will show you how you can make a keto-friendly version with this recipe.
Ingredients:
- Boneless, skinless chicken breast
- Bell peppers (any colors)
- Cilantro, chopped
- Sliced red onion
- Chopped garlic
- Cooking spray
- Ground cumin
- Chili powder
- Lime juice
- Olive oil
The vegetables are perfectly sauteed, the meat is juicy, and the recipe uses the right mix of spices to give the fajitas an authentic “Chilli’s” flavor.
The only thing that’s missing is a bowl of nacho chips, but since you’re on a keto diet and nachos are forbidden, you could try these keto cheesy tortilla chips instead.
17. Classic Recipe for Chicken Fajitas Seasoning
The first fajita seasoning blend that we’ll be showcasing is of the “sweet and savory” kind, and while you will notice that you’ll have to swap out one of the ingredients to make it keto-friendly, the result will be just as delicious.
We found it on Culinary Hill, so head over there and read the full article to find out more about this homemade seasoning mix.
Ingredients:
- Cayenne pepper
- Onion powder
- Garlic powder
- Chilli powder
- Paprika
- Cumin
- Sugar (to be replaced)
All of the ingredients listed are classic fajita spices, except for the sugar, which also happens to be the ingredient we’ll have to swap out.
There are plenty of things you can swap out sugar with, such as monk fruit sweetener or stevia, but the best alternative, in our opinion, is erythritol.
This is because it’s a keto-friendly sugar alcohol that tastes very similar to regular sugar without the negative effects on your blood sugar levels.
18. Chicken Fajita Seasoning Recipe
This next entry is regarded as more versatile since you can use it with chicken and beef fajitas, although we believe it can double as a pretty solid taco seasoning mix.
We found it on All Recipes, and the best thing about it is that you probably already have all of the ingredients in your pantry, which means that you won’t have to go out and buy anything special.
Ingredients:
- Ground paprika
- Cayenne pepper
- Onion powder
- Garlic powder
- Ground cumin
- Chili powder
- Salt
- White sugar (to be replaced)
- Cornstarch (to be replaced)
Unfortunately, this recipe has two ingredients that you’ll have to replace: white sugar and cornstarch.
The white sugar is easy to replace since there are a lot of sugar substitutes out there, and you can easily swap the cornstarch with a keto-friendly thickener, such as Xanthan gum.
19. Marinade Recipe for Chicken Fajitas
If dry rubs don’t cut it for you, you’d be more partial to wet rubs or marinades instead. If that’s the case, then this recipe that we came across on Food & Wine is just what you need.
It’s a pretty straightforward marinade that only requires a few ingredients, and it doesn’t take long to prepare either.
Ingredients:
- Ground cumin
- Vegetable oil
- Minced garlic
- Chile powder
- Lime juice
- Sea salt
- Paprika
- Sugar (to be replaced)
Since the oil binds all of the spices together, we recommend that you use some of the finest oils that you can find, such as extra-virgin olive oil or even avocado oil.
Once you mix all of the ingredients, you can refrigerate the marinade for later or use it right away.
Also, don’t forget to replace the sugar with a keto substitute, or you can simply leave it out altogether.
20. Chicken Fajita Marinade Recipe
The purpose of a marinade is to add flavor to the meat and act as a kind of chemical tenderizer that will make the meat a lot easier to cook.
This chicken fajita marinade recipe from Dinner at the Zoo does both things and more.
Ingredients:
- Lime juice
- Olive oil
- Kosher salt
- Minced garlic
- Ground cumin
- Smoked paprika
- Onion powder
- Chili powder
- Pepper
- Water
- Sugar (to be replaced)
This is one of our more savory seasoning blends thanks to the smoked paprika and the combination of opinion, garlic, and chili powder.
We believe that it would go great with not just chicken but also shrimp or even steak, so feel free to make more of this seasoning and store it for whenever rit’s needed.
Don’t forget to replace the sugar with some other sweet keto substitute.
21. Fajita Recipe for Chicken Marinade
The last marinade on our list comes from Laura Fuentes and is probably the simplest one to make all of the required ingredients are keto-friendly, so there won’t be any need to replace anything.
Ingredients:
- Crushed red pepper flakes
- Fresh lime juice
- Dried oregano
- Cumin powder
- Garlic powder
- Chili powder
- Olive oil
- Paprika
- Salt
The crushed red pepper flakes give it a nice bit of heat without being too overwhelming, and the lime juice helps balance out the flavors.
Speaking of flavors, this recipe can be used on more than just chicken fajitas, so feel free to experiment with other sources of protein as well, such as beef, pork, or shrimp.
