- prep
Preheat the oven and prepare the pan.
Preheat your oven to 220°C (425°F). Line a large rimmed sheet pan with parchment paper for easy cleanup, or lightly grease it.
TIPMake sure the oven is fully heated before the pan goes in. A hot oven is key for getting a nice char on the vegetables. - mix
Make the fajita seasoning.
In a small bowl, combine chili powder, cumin powder, smoked paprika, dried oregano, salt, and black pepper. Stir to mix well.

Season all the ingredients.
1.Place the sliced chicken, bell peppers, and onion on the prepared sheet pan.2.Drizzle olive oil and lime juice evenly over everything.3.Sprinkle the prepared seasoning mix and minced garlic over the top.4.Toss everything together with your hands or two large spoons until evenly coated, then spread into a single, even layer.TIPDon't overcrowd the pan. Spreading the ingredients in a single layer allows them to roast and char instead of steam. - bake · ~22 min
Bake until chicken is cooked through and vegetables are tender.
Place the sheet pan in the preheated oven and bake for 18-22 minutes. At the halfway mark, give everything a good stir for even cooking. The chicken is done when it reaches an internal temperature of 74°C (165°F).
TIPFor a slightly more charred, sizzling-platter effect, switch the oven to broil for the last 2-3 minutes. Watch closely to prevent burning. - serve
Serve immediately with warm tortillas and your favorite toppings.
Once out of the oven, squeeze a little extra fresh lime juice over the sizzling fajitas. Serve the chicken and vegetable mixture straight from the pan with warm flour or corn tortillas, and set out small bowls of sour cream, salsa, and guacamole for everyone to build their own fajitas.
TIPWarm tortillas directly over a gas flame for a few seconds per side, or wrap a stack in foil and warm in the oven for the last 5 minutes of cooking.
