• Tortillas (flour or corn)

For the Fajita Seasoning:

• Chili powder

• Garlic powder
• Onion powder

Instructions

Step 1: Preheat the Oven

Start by preheating your oven to 400°F (200°C). This high heat is essential for getting the chicken nice and crispy, while the veggies soften and caramelize perfectly. Line a large baking sheet with parchment paper or foil for easy cleanup—trust me, you’ll thank yourself later.

Step 2: Season the Chicken & Veggies

Now, grab a large mixing bowl and toss the sliced chicken, bell peppers, and onions with olive oil and lime juice. This gives everything a lovely coating that helps the seasoning stick.

Next, in a smaller bowl, combine all of your fajita seasoning ingredients. The chili powder, cumin, smoked paprika, garlic powder, and a dash of oregano create the perfect smoky, zesty flavor profile. Salt and black pepper balance everything out, and if you like a little heat, add some red pepper flakes. Sprinkle the seasoning over the chicken and veggies, tossing everything together to coat it all evenly.

Step 3: Roast to Perfection

Spread the seasoned chicken and veggies evenly on the baking sheet in a single layer. This ensures that everything roasts evenly and gets a nice char. Pop the baking sheet in the oven and roast for 20-25 minutes. Halfway through, give everything a good toss so the chicken cooks evenly. When the chicken reaches an internal temperature of 165°F (75°C) and the veggies are tender, you’re ready for the next step.

For a little extra smokiness, you can broil the fajitas for 2-3 minutes at the end. This will give them that perfect charred finish, making them even more irresistible.

Step 4: Assemble & Serve

While the fajitas roast, warm your tortillas. You can do this by heating them in a dry skillet over medium heat for about 30 seconds per side, or you can wrap them in foil and heat them in the oven for a few minutes.

Once the chicken and veggies are done, assemble your fajitas by placing the roasted chicken and veggies on the warmed tortillas. Top with your favorite toppings like fresh cilantro, sour cream, guacamole, or shredded cheese. Squeeze a little extra lime juice over the top for a fresh, zesty kick.

Tips and Tricks for Perfect Fajitas

Want extra spice? If you love a fiery kick, add cayenne pepper or some fresh jalapeños to the mix.

Load up on veggies – Fajitas are all about that vibrant, crunchy texture. Add extra veggies like zucchini, mushrooms, or cherry tomatoes to bulk up the meal with more nutrients and color.

Cheesy fajitas, anyone? If you’re a cheese lover, melt some cheese over the chicken and veggies before serving. Monterey Jack, cheddar, or even cotija work wonderfully with the flavors in this dish.

Grill it – If you’re feeling adventurous, you can grill the chicken and veggies instead of roasting them. Grill over medium-high heat for 6-8 minutes, turning occasionally until the chicken is cooked through and the veggies are tender.

Low-carb option – Skip the tortillas and serve the fajita filling over lettuce wraps or a bed of cauliflower rice. This is a great option if you’re following a low-carb or keto lifestyle.

Storage Instructions

Leftovers are a wonderful thing when it comes to this recipe! Store any extra fajita filling in an airtight container in the fridge for up to 4 days. To reheat, simply warm in a skillet over medium heat or microwave in 30-second intervals until heated through.

If you’d like to store them for a longer period, you can freeze the cooked chicken and veggies. Just place them in a freezer-safe container or zip-top bag and freeze for up to 3 months. When you’re ready to eat, let them thaw in the fridge overnight, and then reheat as usual.

Serving Suggestions

• Serve with Mexican rice and beans – For a hearty, complete meal, pair your fajitas with a side of Mexican rice and black beans. These sides complement the fajitas perfectly and make the meal even more satisfying.
• Add pickled onions – A little tang goes a long way. Try adding some pickled onions or jalapeños for an extra burst of flavor.
• Toppings galore – The possibilities are endless when it comes to toppings. Try adding salsa, pico de gallo, or a drizzle of hot sauce to suit your taste.
