How To Make Keto Chicken Fajitas
I don’t feel like you could find a much easier method for making chicken fajitas. And the flavor is beyond amazing. So it’s pretty much a no-brainer for me to cook this chicken dish often.
First Step: Start by preheating the oven to 400 degrees F.
Second Step: Mix the chicken, peppers, and onions with the seasonings and oil.
Third Step: Place all the ingredients on a large rimmed baking sheet and cook them for 35-40 minutes or until the veggies are soft and the chicken is done.
Seasoning for Low Carb Chicken Fajitas

What Are Some Topping Ideas for Keto Chicken Fajitas?
There are lots of foods you can put on top of your keto chicken fajitas. Honestly, they are so delicious I could eat them plain without any toppings! However, I often serve them with a variety of foods to add to them so everyone can have their own custom meal. Here are some ideas of things to try:
- Cheese - If you tolerate dairy, cheese is always a great idea. Most people stick with traditional cheddar, but you could try other varieties like Pepper Jack.
- Guacamole - It’s not possible to ever have enough keto guacamole on top of fajitas!
- Salsa - Use your favorite keto salsa to add some pizzazz to your homemade fajitas.
- Sour Cream - A dollop of sour cream adds a yummy coolness to the dish that’s so good.
- Cilantro - Sprinkle on some cilantro to add some flavor and extra color.
- Ranch - This Dairy-Free Ranch is my dressing of choice when having a fajita salad.
If you are doing Whole30 or paleo just skip the cheese and sour cream!
Are Chicken Fajitas Healthy?
Yes, keto chicken fajitas are really healthy! You will get some great nutrients when you devour these amazing oven baked chicken fajitas. Potassium, niacin, magnesium, zinc, vitamin B, folate, and vitamin C are a few of the vitamins and minerals you get.
Do I Have To Use Chicken Thighs?
No, you don’t have to use boneless skinless chicken thighs if you don’t want to. You could go with chicken breast if you’d rather. Keep in mind if you decide to use chicken breast, I suggest cooking the onions and peppers for 15 minutes before adding the chicken. Make sure not to over bake the chicken, so it doesn’t get too dry.
I just prefer the chicken thighs because they are a moist and fattier cut of meat. It leads to a super juicy and flavorful dish that’s hard to beat. However, if you aren’t a fan of thighs, that is completely okay!
How Do You Cut Chicken For Fajitas?
You can cut the chicken however you like, but it’s best to cut it into thin strips. Try to cut the chicken into horizontal pieces that are no wider than ½ inch. They will be the perfect texture and thickness for your fajitas.
What Do You Eat The Keto Chicken Fajitas With?
You can eat these baked chicken fajitas in several ways. Try out new things to see how you like them best. Here are my favorite ways to eat them:
- Plain - Eat a chicken fajita bowl without any type of taco shell. It’s so good, and you don’t have to worry about one more step!
- Gluten-Free Tortilla - You can use a tortilla that is gluten and grain-free and low carb.
- Lettuce Wrapped - I love eating fajitas in a lettuce wrap. Just take a piece of lettuce, add the filling and fold it up like you would a burrito. It’s so amazing and a healthy option.
Or, for a fancier presentation try my Fajita Stuffed Chicken! That meal is company-worthy.
How Do You Store Fajita Chicken?
Chicken fajitas will last for 4-7 days in the fridge if they are kept in a sealed container. If you want to freeze them, it’s better if you prepare the low carb chicken fajitas but don’t actually bake the keto chicken fajitas until the day you want them. Cooked peppers and onions tend to have a strange texture after they have cooked and been frozen.

Thank you so much for being real, a lot of low carb recipes are not really low carb and I'm so tired of trying to find recipes that are. I have type 2 diabetes and I'm obese of 100 pounds overweight and trying to eat real low carb meals, that are not expensive to make, my daughter also has health issues and needs to lose 60 pounds. I just want to say I signed up to receive your recipes so that we can get our lives back before our eating became out of control and now have health issues that will eventually lead to death. Thank you for caring enough to put your recipes on Pinterest.
