Instructions
1-First Step: Prep Your Pan and Ingredients Begin by lightly greasing a large sheet pan with non-stick cooking spray to prevent sticking. Slice the 1 1/2 pounds of boneless skinless chicken breasts into 1/2-inch thick strips, and prepare the vegetables by coring and slicing the 3 bell peppers and thinly slicing 1 yellow onion. This mise en place helps everything cook evenly and saves time later.
2-Second Step: Arrange on the Pan Lay the sliced vegetables evenly across the prepared pan, then place the chicken strips on top for even heating. Preheat your oven to 425 degrees F so it’s ready when you are. Combine all the fajita seasoning ingredients in a small bowl and stir well to mix this step builds the flavor base.
3-Third Step: Season and Add Flavor Sprinkle most of the seasoning over the chicken and some over the vegetables for balanced taste. Spoon the 2 minced garlic cloves onto the chicken, then drizzle 3 tablespoons of olive oil over the entire pan. Toss everything together right on the pan and spread it into a single, even layer to ensure it cooks uniformly.
4-Fourth Step: Bake to Perfection Slide the pan into the preheated oven and bake for 15-20 minutes, checking that the chicken reaches an internal temperature of 165 degrees F. In the last 5 minutes, wrap 8-10 small flour tortillas in foil and pop them in the oven to warm. For a variation, try techniques from our grilled chicken recipes if you’re in the mood for outdoor flavors.
5-Fifth Step: Finish and Serve Once done, remove the pan from the oven and squeeze the juice from 1 lime over the chicken and vegetables for a fresh twist. Sprinkle with 1/4 cup chopped fresh cilantro to add brightness. Serve immediately in the warm tortillas, topped with options like sour cream, sliced avocado, pico de gallo, or shredded cheese for a customizable meal. The total time is just 25 minutes, making it ideal for busy nights.
