Heat your oven to 375°F (190°C). This gives it time to get nice and hot before the veggies and chicken go in.
Grab a big mixing bowl and toss in the diced chicken, olive oil, paprika, garlic powder, onion powder, Mexican chili powder, dried oregano, cumin, salt, and black pepper.
Give it a good mix. Coat every piece. Think of this as a little food spa moment.
Now add the minced garlic, sliced peppers, and red onion. Mix again until everything is covered in that delicious spice blend.
Line your sheet pan with parchment paper (or give it a little grease). Spread the chicken and veggies into a single layer.
This helps them roast instead of steam, which means more flavor and those tasty browned edges we love.
Pop the pan in the oven and cook for 30–35 minutes, or until the chicken is fully cooked and looks beautifully golden.
If your oven runs hot or cold (mine has a mind of its own some days), check a piece of chicken to make sure it’s done.
Warm your tortillas while the fajitas finish cooking. You can heat them in a pan, the oven, or even the microwave under a damp paper towel.
Warm tortillas make everything taste better — it’s just a fact.
Now the fun part! Spoon a generous amount of the chicken and veggie mixture onto a tortilla. Top with:A squeeze of lime, Avocado chunks, A dollop of sour cream, A sprinkle of mozzarella, A little cilantro Let everyone assemble their own. Kids love it, grown-ups love it… and somehow dinner feels like a mini fiesta.
