A healthy chicken fajita taco recipe:

Not only is this recipe totally delicious, but it’s also full of nutrients. You can’t go wrong with a meal of essentially protein and veggies, which is what makes up these easy chicken fajita tacos.

It’s subtle differences in quality that makes these fajita tacos different than any fajitas you might find at your local Mexican restaurant.

Using avocado oil, instead of canola – adding extra vegetables and spices into the meat mixture – using organic, pasture raised meat instead of commercial – and choosing gluten- or grain- free tortillas of choice.

Chicken is a complete protein that helps balance blood sugar and keep you feeling satiated longer, providing all essential amino acids.
Bell peppers give tons of flavor to your meal and are packed with vitamin C. Use any color you’d like for a boost of antioxidant properties, vitamin A and fiber.
Onions are of course an essential component of any good fajita taco and are SO good for you! Red onions are also a rich source of quercetin, sulfur compounds that support the liver and prebiotic fibers that support gut health.

Try these variations of fajita tacos:

Add any vegetables you’d like. This recipe keeps it easy and somewhat traditional using bell peppers, onion and mushrooms. But feel free to add any of your favorite vegetables for more fiber and antioxidants. Zucchini, cauliflower, broccoli florets, pablano peppers or organic corn would be great additions.
Make it a fajita taco bowl! Serve the fajita filling on top of shredded lettuce, white, brown or cauliflower rice.

What You’ll Need For The Best Fajitas Tacos

Just like any meal, tacos should be a balanced meal, filled with protein, veggies and healthy fats, wrapped up in your tortillas of choice.

You’ll need:

Chicken, I recommend organic and pasture raised
Bell Peppers, any color will do!
Red Onion
Mushrooms
Avocado Oil
Lime Juice & Zest
Spices! You can make your own mix of oregano, paprika, garlic powder, cumin, coriander and cayenne, but a taco seasoning or chili powder will work too.
Tortillas: I recommend organic corn or grain free tortillas from Siete Foods.
Your favorite toppings! I love avocado, radishes, salsa, green onion and Forager’s Cultured Dairy Free Sour Cream.

How to make the recipe

Start by marinating the chicken: Slice the chicken thighs into ½ inch thick slices and add to a bowl along with the bell peppers, onion, mushrooms, avocado oil, lime, salt and fajita seasoning. Mix everything to combine and make sure the spices are evenly dispersed.
Cook the chicken, onions, and bell peppers: Pour the contents onto a lined sheet tray and bake for 20 minutes until the chicken is cooked through and vegetables are starting to char.
Warm up the tortillas: While the fajitas are cooking, warm up the tortillas in a dry skillet or on an open flame.
Assemble the tacos: Once everything is cooked, it’s time to enjoy the tacos. Start with a warm tortilla, then add some of the chicken, onions, and bell peppers. Top with some fresh cilantro and a squeeze of lime juice.
Serve and enjoy: Serve the tacos with your favorite toppings, such as radishes, green onion, salsa, guacamole, or sour cream.

Tips For Healthier Sheet Tray Cooking

Always consider what type of sheet pan are you using in the oven?

Aluminum pans leach into food, especially when using acidic ingredients like citrus or tomatoes. Those metals that leach into your food can then be stored in your body and cause inflammation.

To avoid the risk of ingesting heavy metals, it’s best to use stainless steel or non toxic pans, or line your pans with parchment or a silicon oven mat when cooking.

FAQ

Q: What toppings do you put on chicken fajita tacos?
A: Top your fajita tacos with a squeeze of lime juice, sliced avocado, radishes, salsa, dairy free cheese and sour cream, cilantro, sliced jalapeños, and homemade guacamole. Use your favorites!

Q: Is taco seasoning different from fajita seasoning?
A: There are very similar. Taco seasoning may have more oregano and chili powder than fajita seasoning, while fajita seasoning is more cumin heavy. Either way, the flavors are great in both! So if you have taco seasoning on hand at home, feel free to use that.

Q: What is the best way to cut chicken for fajita tacos?
A: I recommend cutting in ½ inch thick strips, just like a fajita you’d order at a restaurant!

How to store your easy chicken fajitas or meal prep:

This is the perfect meal prep recipe! Don’t be afraid to double or triple the recipe on a couple racks in the oven. Make half with chicken, half with steak or your favorite meat.

Once you’ve made the fajita filling, you can use it in so many ways to put together a quick meal because fajitas aren’t just for tacos!

Serve over lettuce for a taco salad. Mix with beans and top with a fried egg and have yourself a pseudo huevos rancheros. Chop it up and make enchiladas!
