Step‑by‑Step Instructions for Sheet Pan Chicken Fajitas
Step 1: Make Fajita Seasoning
In a small bowl, combine the chili powder, cumin, garlic powder, and paprika to create your fajita seasoning. Mix well until all ingredients are evenly distributed, ensuring a burst of flavor in your Sheet Pan Chicken Fajitas. Set this bowl aside as you prepare to coat your chicken and vegetables.
Step 2: Coat Chicken and Vegetables
In a large mixing bowl, toss the chicken tenders, sliced bell peppers, and onions with olive oil and the prepared fajita seasoning. Ensure every piece is thoroughly coated to maximize flavor. This vibrant medley will roast beautifully together on your baking sheet, giving you that irresistible Tex-Mex aroma.
Step 3: Prepare the Baking Sheet
Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup. Once the oven is ready, spread the chicken and vegetable mixture evenly across the sheet, making sure not to overcrowd it. This will allow the ingredients to roast nicely, enhancing their flavors.
Step 4: Roast the Mixture
Place the baking sheet in the preheated oven and roast for about 15 minutes. Use a spatula to stir the mixture halfway through for even cooking. You’ll know it’s nearly done when the chicken is cooked through and the vegetables are tender and slightly caramelized, showcasing their beautiful colors.
Step 5: Broil for a Perfect Finish
After roasting, switch your oven to the broil setting and keep a close eye on the fajitas. Broil for an additional 2-3 minutes until the chicken is lightly browned and the vegetables have a perfect char. This step adds depth and enhances the appeal of your Sheet Pan Chicken Fajitas.
Step 6: Assemble and Serve
Remove the sheet pan from the oven and let it cool slightly. Warm your tortillas, then spoon the chicken and vegetable mixture into each tortilla. Top with your favorite garnishes like avocado, salsa, or cheese, making it a delightful assembly of flavors ready for your family to enjoy!

Make Ahead Options
These Sheet Pan Chicken Fajitas are perfect for busy cooks looking to save time during the week! You can marinate the chicken and toss it with the vegetables, along with the fajita seasoning, up to 24 hours in advance. Simply refrigerate the mixture in an airtight container to enhance the flavors while maintaining quality. When you’re ready to serve, spread the mixture on a baking sheet and roast as directed, adjusting the cooking time slightly if the ingredients were chilled. This way, you’ll have a delicious, hassle-free dinner on the table with minimal effort! Enjoy the same vibrant taste and aroma, just prepared ahead of time!
