Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). Lightly grease or line a large sheet pan with parchment paper.
Step 2: Prepare the Ingredients
Slice the chicken into thin strips. Slice the bell peppers and onion into similar-sized strips.
Step 3: Season Everything
In a large bowl, combine:
- Olive oil
- Chili powder
- Smoked paprika
- Cumin
- Garlic powder
- Onion powder
- Oregano
- Salt
- Black pepper
Add the chicken, peppers, and onion. Toss until everything is evenly coated with the seasoning.
Step 4: Arrange on the Sheet Pan
Spread the chicken and vegetables into a single layer on the prepared baking sheet. Avoid overcrowding for the best roasting results.
Step 5: Bake
Bake for 20–25 minutes, stirring halfway through, until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender with lightly caramelized edges.
Step 6: Finish with Lime
Remove the pan from the oven and squeeze the fresh lime juice over the chicken and vegetables. Sprinkle with chopped cilantro if desired.
Step 7: Serve
Serve the fajita mixture in warm tortillas with your favorite toppings, or enjoy it over rice, cauliflower rice, or a fresh salad for a lighter meal.
Tips
- Marinate the chicken for 30 minutes before cooking for even more flavor.
- Add sliced mushrooms or zucchini for extra vegetables.
- Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheat in a skillet over medium heat for the best texture.
