Sheet pan chicken fajitas make busy weeknights delicious and easy. This reliable recipe brings colorful bell peppers and juicy chicken together on one pan for a hands-off dinner with southwest flavor. With just a little prep you get healthy restaurant-style fajitas without the mess or stress. Taco night has never been so simple or so tasty.
I first made these when my oldest son brought home friends after soccer and the whole pan disappeared. Now it is my go-to whenever the family needs something fast but still crave-worthy.
Ingredients
- Boneless skinless chicken breasts: choose fresh chicken that is firm to the touch and pink with no odor these soak up the seasonings beautifully and stay tender when sliced
- Red green and yellow bell peppers: look for peppers with shiny skin and good heft the color mix gives a sweet mellow flavor and eye-catching appeal
- Yellow or white onion: fresh onions should be heavy for their size with no soft spots they add caramelized sweetness and depth
- Olive oil: use extra virgin for the best flavor and heart-healthy fats it helps the spices stick to every bite
- Chili powder: this is the backbone of fajita flavor and I always reach for a mild blend so the whole family can enjoy
- Cumin: brings a warm earthy taste and authentic Mexican aroma make sure your cumin is fragrant not musty
- Garlic powder: choose a fine powder that smells like fresh garlic for the most punch
- Salt: essential for drawing out the flavor of every ingredient
- Dried oregano: use a Mexican variety if you can for a citrusy note
- Red pepper flakes: add as much or as little as you like for gentle heat
- Black pepper: use fresh cracked for a more complex flavor lift
- Flour tortillas: soft and flexible choose fajita-size for easy serving
- Sour cream guacamole salsa: pick your favorites for creamy or zesty toppings I love making my guacamole from scratch but store bought is great in a pinch
Step-by-Step Instructions
- Marinate the Chicken and Veggies:
- Add the sliced chicken and all pepper and onion strips to a large zip top bag Mix the olive oil chili powder cumin garlic powder salt oregano red pepper flakes and black pepper in a separate bowl then pour over the chicken mixture Seal and shake the bag well so every piece is evenly coated For best results let it rest in the fridge for at least thirty minutes two hours is my favorite for deeper flavor
- Prepare the Sheet Pan:
- Preheat your oven to four hundred degrees Fahrenheit Line a large rimmed baking sheet with foil and lightly coat with nonstick spray Arrange the marinated chicken and veggies in a single even layer on the pan to ensure they roast not steam
- Roast the Fajitas:
- Slide the sheet pan into the oven and bake for eighteen to twenty two minutes or until the chicken is cooked through and vegetables are tender but still have a slight bite Rotate the pan halfway through for even cooking The chicken should be opaque and the peppers just beginning to blister
- Warm the Tortillas:
- During the last five minutes of baking wrap the fajita tortillas in foil and place them on a lower oven rack so they turn soft and pliable for serving
- Serve and Top:
- Spoon the hot chicken and veggie mixture into warm tortillas Top with sour cream guacamole salsa or any favorite garnishes I like adding a handful of fresh cilantro or a spritz of lime

Storage Tips
After dinner let any leftovers cool before transferring them to an airtight container You can store the chicken and veggies together but keep the tortillas separate in their own zip bag They will last up to three days in the refrigerator Reheat in a skillet or microwave until steaming hot Always refresh the toppings just before serving
Ingredient Substitutions
Swap boneless chicken thighs for extra juicy results or use firm tofu for a vegetarian twist Any colored bell pepper will work and thin strips of portobello mushroom make a rich earthy addition If you are out of tortillas serve everything over a bowl of rice or quinoa
Serving Suggestions
Turn your fajitas into a fun fajita bar for gatherings with bowls of shredded cheese pickled jalapenos chopped tomatoes and crisp lettuce on the side Sometimes I spoon everything over greens for a salad or scoop the leftovers onto nachos and bake for an easy appetizer
