Tips & Variations
- Use chicken breasts instead of thighs for a leaner option, adjusting cooking time slightly to avoid dryness.
- Add sliced jalapeños or a pinch of cayenne pepper to the fajita seasoning for extra heat.
- To keep veggies crisp, slice them thicker and check doneness halfway through baking.
- Serve with toppings like sour cream, guacamole, or shredded cheese to customize your fajitas.
Storage
Store leftover chicken fajita mixture in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave until warmed through. Tortillas are best warmed separately to maintain texture.

FAQs
Can I make this recipe gluten-free?
Yes, just swap the flour tortillas for corn tortillas or gluten-free tortillas to keep the meal gluten-free.
What can I use if I don’t have all the fajita seasoning spices?
You can use a pre-made fajita or taco seasoning blend as a convenient substitute. Alternatively, simple chili powder, cumin, and garlic powder alone will still give good flavor.
