- 1½ tbsp olive oil
- 1 lime, juiced
For the Fajita Seasoning
- 2 tsp chili powder
- 1 tsp smoked paprika
- 1 tsp ground cumin
- 1 tsp garlic powder
- ½ tsp onion powder
- ½ tsp dried oregano
- ½ tsp salt
- ¼ tsp black pepper

Instructions
1. Prepare the Oven
Preheat the oven to 425°F (220°C). Lightly grease a large sheet pan or line it with parchment paper.
2. Prepare the Seasoning
In a small bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, salt, black pepper, and cayenne pepper if using.
3. Season the Chicken
Place the sliced chicken in a large bowl. Add about half of the olive oil, lime juice, and fajita seasoning.
Toss until the chicken is evenly coated.
4. Prepare the Vegetables
Add the sliced bell peppers and onion to the same bowl. Add the remaining olive oil and seasoning, then toss until evenly coated.
5. Arrange on the Sheet Pan
Spread the chicken and vegetables across the sheet pan in a single layer. Avoid overcrowding the pan so the ingredients roast instead of steaming.
6. Roast
Bake for approximately 18–25 minutes, stirring or flipping everything halfway through.
Cook until the chicken reaches 165°F (74°C) internally and the vegetables are tender with lightly browned edges.
7. Finish & Serve
Remove from the oven and squeeze fresh lime juice over the fajitas.
Garnish with fresh cilantro and serve with lettuce wraps, low-carb tortillas, or your favorite toppings.
Common Mistakes to Avoid
- Overcrowding the Pan:
Too many ingredients packed together can cause steaming instead of proper roasting. - Cutting Chicken Unevenly:
Try to slice the chicken into similar-sized pieces so everything cooks at the same rate. - Using Too Much Oil:
A moderate amount is enough to coat the chicken and vegetables while helping them brown. - Overcooking the Chicken:
Remove the chicken once it reaches 165°F to help keep it juicy and tender.
Required Equipment
- Large Sheet Pan: Allows the chicken and vegetables to roast evenly.
- Large Mixing Bowl: Makes seasoning and tossing everything easy.
- Sharp Knife: Helps create evenly sized chicken and vegetable strips.
- Measuring Spoons: Ensure the fajita seasoning stays balanced.
- Food Thermometer: Helps confirm the chicken reaches a safe internal temperature.
Storage
Store cooled chicken fajitas in an airtight container in the refrigerator for up to 4 days. Reheat in a skillet, microwave, or oven until hot. Keep fresh toppings separate until serving for the best texture.
