How to Make Easy Sheet Pan Chicken Fajitas
Here are the step-by-step instructions for making this recipe:
Step 1: Preheat the oven to 425°F.
Step 2: Cut the bell peppers into ½-inch slices (Photo 1) and add them to a large baking sheet (Photo 2).
Step 3: Cut the onion into thin slices and add them to the baking sheet (Photo 3).
Step 4: Cut the chicken into ½-inch to 1-inch thick slices (Photo 4) and add them to the rimmed sheet pan (Photo 5).
Step 5: Add the avocado oil and fajita seasoning (Photo 6). Toss with your hands until evenly coated, then spread into a single layer. It’s fine if some chicken rests on top of the vegetables (Photo 7).
Step 6: Bake for 10 minutes. Remove the sheet pan, toss everything, then bake for another 10–15 minutes or until the chicken is fully cooked.
Step 7: Remove from the oven and squeeze fresh lime juice over the fajitas (Photo 8). Warm the tortillas and serve.
Tips for Success
- Slice the chicken and veggies evenly so they roast at the same rate.
- Use colored peppers, green bell peppers, or a combination.
- Don’t overcrowd the pan—use two pans if needed for better caramelization.
- Add extra garlic powder, onion powder, or chili powder for a flavor boost
- Add your favorite fajita toppings like sour cream, lime wedges, salsa, cilantro, or shredded cheese for extra flavor.

Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat in a skillet or microwave until warm.
