Let’s Make it together
Preheat the Oven: Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup later.
Prepare the Chicken and Vegetables: Slice the boneless chicken breasts into thin strips. Chop bell peppers and onion into bite-sized pieces to ensure even cooking.
Toss with Seasoning: In a large bowl, combine the chicken strips and chopped vegetables. Drizzle with olive oil and sprinkle in the fajita seasoning until everything is coated evenly.
Spread on Baking Sheet: Transfer the seasoned mixture onto your prepared baking sheet in an even layer. Make sure there’s enough space between pieces so they roast nicely rather than steam.
Bake Away: Place the baking sheet in the preheated oven and bake for about 20 minutes until the chicken is cooked through and veggies are tender-crisp.
Squeeze Lime Juice Before Serving: Once out of the oven, drizzle fresh lime juice over everything. This step adds brightness that elevates all those wonderful flavors!
Now you’re ready to assemble your fajitas! Grab those warm tortillas and fill them up with this beautiful medley of flavors.
Whether you’re hosting friends or just treating yourself on a cozy night in, these sheet pan chicken fajitas will not disappoint. Enjoy every bite while savoring that satisfying crunch from freshly roasted vegetables paired with tender chicken!
