Why You'll Love It
Easily adapted to many eating styles- If your household has mixed eating styles, finding a meal that satisfies everyone's dietary preferences can be a challenge. With its focus on protein and vegetables, this recipe can easily be adapted to suit a variety of dietary needs. The flexibility of sheet pan chicken fajitas makes it easy to please everyone at the table while still providing a healthy and delicious option.
Low prep- This meal comes together quickly and doesn't require much prep other than cutting the veggies and chicken. Some nights, it feels like there's barely even enough time for that! You can easily do all the cutting ahead of time, up to 2 days, for the best taste. Then all you have to do is preheat the oven and bake!
Freezer friendly- This easy sheet pan recipe also makes an excellent freezer meal! Slice up the peppers, onions, and chicken and par freeze them on a sheet pan for 2-3 hours. This will prevent the pieces from sticking together. Then, just scoop them all into a large sealable freezer bag. You can season them before freezing, but personally, I don't find that it makes a huge difference in taste.
Other Mexican Style Keto Recipes
What ingredients do you need to make chicken fajitas?
- Boneless skinless chicken breasts- You can certainly use boneless chicken thighs for this recipe too! I find that boneless and skinless varieties are simply easier to work with, but if you already have some chicken on hand, feel free to debone it and use it in this recipe. You may need to adjust the cooking time slightly depending on the thickness of the cut. You can choose to use organic chicken breast, but it's not required. Chicken tenders will work as well.
- Fajita Seasoning - Fajita seasoning is a blend of chili powder, cumin, garlic powder, dried oregano, and other spices to give the recipe a smoky flavor. You can buy a packet at the store or make your own keto friendly fajita seasoning. Alternatively, you can use taco seasoning or your own preferred fajita blends.
- Bell Peppers- Red bell peppers and green bell pepper that are thinly sliced give this meal lots of nutrients and flavor. Feel free to add orange bell peppers or yellow bell peppers and adjust the amounts to your preference. I like the mix of sweet red bell peppers and mild green for these, but you can definitely get creative.
- Yellow Onion- Onions are a traditional fajita ingredient that add a sweet caramelized flavor to these sheet pan chicken fajitas. Onions cook quickly, so be sure to cut them into thicker pieces so that they don't overcook before the chicken is done.
- Olive Oil- Olive oil is used for drizzling over the chicken and vegetables. Since chicken breast is a leaner cut of meat, it also helps keep it moist and juicy while baking.
How to Make Sheet Pan Fajitas
- Preheat the oven to 400 degrees. Prepare a large sheet pan or rimmed baking sheet with cooking spray or foil for easy clean up.
- Place the chicken, peppers, and onion slices into a large bowl. Drizzle olive oil and toss to coat.
- Sprinkle the fajita seasoning, salt, and freshly ground black pepper into the bowl and toss to coat evenly.
- Place all the ingredients onto the prepared baking sheet and arrange the seasoned chicken mixture in a single layer. Bake for 20 minutes or until the vegetables are tender and the chicken has an internal temperature of at least 165 degrees. Serve warm with a choice of sour cream, guacamole, and a squeeze of fresh lime juice, if desired.

Low carb tortillas, homemade keto tortillas. If you're not low carb, warm flour tortillas, corn tortillas, and gluten-free tortillas are all delicious. Just be sure to use warm tortillas. They taste better!

Cauliflower rice makes an excellent base for a bowl meal. Mexican style Cauliflower Rice and cilantro lime cauliflower rice are both full of flavor and easy to make.

FAQ Sheet Pan Fajitas
How do you cook fajita meat so it's tender?
The key to cooking perfectly tender fajita meat is not to over cook it. It's very easy to overcook meat, whether it's baked or cooked in a skillet. Keep a meat thermometer close by to take the guesswork out and get perfectly tender meat every time.
Can you cook fajitas in a nonstick skillet?
Absolutely! These fajitas are made for the oven, but you can easily cook them in a skillet or in the air fryer. To cook fajitas in the skillet, I prefer to cook the meat and vegetables separately. Add the seasoned chicken and a drizzle of olive oil to a large skillet over medium heat.
Cook the meat first to get a nice brown sear. Once it's about halfway cooked, add the veggies to the same skillet or a separate one and cook until the chicken is fully cooked and the veggies are tender to your liking.
Do you cut fajita meat before it's cooked?
For this recipe, you cut the chicken before it's cooked for a shorter cook time and one that works with the veggies. For some fajitas, such as steak fajitas, it's normal to sear the steak first and let it rest before cutting into it. This allows the juice to redistribute through the meat and not all leak out when it's cut open, which would leave it dry.
Do fajitas need tortillas?
Nope! They taste amazing on top of salad, or as a rice bowl!
Can I use greek yogurt instead of sour cream?
Plain greek yogurt is an excellent swap for sour cream. For those who follow lower in fat diets, Greek yogurt is an excellent option.

Some people following a keto diet choose to avoid vegetables like peppers and onions because they are higher in carbs, but in my opinion they're not high enough in carbs to be completely ruled out.
