Sheet Pan Chicken Fajitas

Sheet Pan Chicken Fajitas are the perfect example of how simple ingredients can create an incredibly flavorful and satisfying meal. This recipe brings together juicy strips of chicken, vibrant bell peppers, and sweet onions—all tossed in a bold, smoky fajita seasoning and roasted to perfection on a single sheet pan.

It delivers everything you love about traditional fajitas but with far less effort and minimal cleanup.

Why i love this recipe

I love this recipe because it’s incredibly efficient without sacrificing flavor. The oven does most of the work, allowing the ingredients to caramelize and develop a depth of flavor that stovetop cooking sometimes can’t achieve.

It’s also a fantastic choice for busy weeknights, meal prepping, or feeding a crowd, since everything cooks evenly in one pan. You get tender chicken, beautifully roasted vegetables, and perfectly seasoned fajita filling in under 30 minutes.

This is a must try dish

This is a must-try dish because it’s quick, versatile, and healthier than takeout fajitas. The homemade seasoning blend adds a warm, bold, zesty flavor, and you can customize the heat level to your liking.

Plus, sheet pan cooking saves time, reduces mess, and still delivers that sizzling, satisfying fajita experience everyone loves.

How to Serve

• Serve the chicken and vegetables inside warm tortillas, topped with sour cream, guacamole, salsa, or cheese.
• Add lime wedges on the side for fresh brightness.
• Pair with Mexican rice, black beans, or a fresh salad for a complete meal.
• Create a fajita bar for family gatherings by offering multiple toppings like shredded lettuce, jalapeños, or pickled onions.

Recipe Tips

• Slice everything evenly to ensure uniform cooking.
• For juicier chicken, marinate the mixture for 30 minutes before baking.
• Do not overcrowd the sheet pan; this helps ingredients caramelize instead of steam.
• Use a high heat setting (425°F) to get those classic fajita-style roasted flavors.
• Add a tablespoon of lime juice to the seasoning mixture for extra tang.
