Method
Preheat the Oven
First things first set your oven to 425°F (220°C). It’s important to let it fully preheat while you prepare the rest of the ingredients so everything bakes evenly and gets that perfect roasted flavor. A properly preheated oven helps the chicken cook through while the peppers and onions get that nice, slightly charred edge.
Prepare the Fajitas
Grab a large baking sheet and place your sliced chicken breast strips right on it. Then, toss on the colorful trio of bell peppers red, yellow, and green along with your sliced onion. Add the pressed or grated garlic over the top for that rich, savory base. Now comes the flavor magic: sprinkle all the dry seasonings garlic powder, onion powder, smoked paprika, chili powder, ground cumin, chicken bouillon powder, salt, and black pepper over the mixture. Drizzle the avocado oil evenly on top, and then use clean hands, a big spoon, or kitchen tongs to toss everything together. Make sure the chicken and veggies are all well coated with the spices and oil. Spread the mixture out into a single, even layer so it all roasts properly and doesn’t steam.
Bake
Take your halved lime and place each piece cut side up right on the baking sheet with the chicken and veggies. As they roast, the limes will mellow and get extra juicy perfect for squeezing later! Pop the baking sheet into the oven and let it bake for about 20 to 25 minutes. Keep an eye on it around the 20-minute mark. You’ll know it’s ready when the chicken is cooked through (no pink inside!) and the vegetables are soft and starting to get golden edges.
Add the Cheese
Once the chicken and veggies are done, carefully remove the baking sheet from the oven (don’t forget those oven mitts!). Sprinkle the shredded Monterey Jack cheese evenly over the hot fajita mix. Return the sheet to the oven for just 2 to 3 minutes just enough time for the cheese to melt and get gooey. This step brings everything together and adds that cheesy, comforting finish.
Serve and Enjoy!
Now for the final touch: take those roasted lime halves and squeeze the warm, caramelized juice all over the fajitas. This adds a fresh, zesty burst that makes all the flavors pop! Spoon the cheesy chicken and veggie mix into warm flour tortillas and top them however you like. Whether you go for a dollop of sour cream, a scoop of guacamole, or a sprinkle of fresh cilantro, it’s all up to you. And just like that you’re ready to dig in!
