Baked chicken fajitas are one of those dinners that feel like you put in way more effort than you actually did. Chicken, bell peppers, and onions go on one pan, get tossed in a simple homemade seasoning, and roast in the oven while you do literally anything else. Dinner is ready in about 35 minutes with one pan to clean.
I created this recipe for the nights when you want something that feels like a real dinner but you just can't deal with a lot of steps. Everything goes on one pan, the oven handles it, and you're sitting down to eat in under 40 minutes. If you love easy weeknight chicken recipes, these fajitas are going to earn a permanent spot in your rotation.
Ingredients & Substitutions
Chicken Breasts - Boneless, skinless chicken breasts work great here. Slice them thin so they cook quickly and evenly. Boneless chicken thighs are a juicy swap if that's what you have on hand.
Bell Peppers - Use whatever color you like! Red, yellow, and orange peppers are sweeter and look great on the pan. Green bell pepper has a more earthy, slightly bitter flavor.
Onions - Yellow onions are the classic choice. Red or white onions work just as well depending on what you prefer.
Olive Oil - Helps the seasoning stick and gets the veggies roasting (not steaming). Avocado oil or vegetable oil works too.
Limes - Fresh lime juice squeezed right before serving is what makes fajitas taste like fajitas. Bottled lime juice works in a pinch.
Flour Tortillas - Soft taco-size flour tortillas are the classic pick. Corn tortillas or low-carb wraps work too. Warm them the last 5 minutes of baking so they're soft and ready to go.
Seasoning - The homemade spice blend gives you full control over salt and heat. A store-bought fajita packet works if you're short on time - just watch the salt.
Cayenne - Totally optional. Leave it out for a mild version, or add extra if you want a little kick.

How to Make Sheet Pan Chicken Fajitas
Step 1 | Prep the Ingredients
Slice the chicken, bell peppers, and onion.
Step 2 | Season and Toss
Place the chicken and veggies on a sheet pan, sprinkle with seasoning, drizzle with oil, and toss to coat.
Step 3 | Roast
Bake at 425°F for 15-20 minutes, until the chicken is cooked and the veggies are tender. Warm tortillas in foil during the last 5 minutes.
Step 4 | Finish and Serve
Squeeze fresh lime juice over the pan, sprinkle with chopped cilantro, and serve in warm tortillas with your favorite toppings.
Tips
Cut Evenly - Slice the chicken and veggies into similar sizes so everything finishes cooking at the same time. Thicker pieces of chicken will take longer, which means your veggies can get overcooked before the chicken is done.
Don't Crowd the Pan - Give everything some breathing room. If the pan is too packed, the chicken and veggies will steam instead of roast, and you'll miss out on those caramelized edges. Use two pans if needed.
Customize the Heat - Leave out the cayenne for a mild version. Add a pinch more if you like things spicy. You're in control here.
Common Questions
Can I use chicken thighs instead of breasts? Yes! Boneless, skinless chicken thighs are juicier and work great. Slice them thin and cook as directed, they finish around the same time.
Can I use store-bought fajita seasoning? Absolutely. A packet of fajita seasoning works fine if you're short on time. Just check the salt content before adding more, since some packets run salty.
Can I add other vegetables? Yes! Zucchini, mushrooms, and cherry tomatoes are all great additions. Slice them thin so they roast at the same rate as the peppers and onions.
Can I make this ahead? You can slice the chicken and veggies and refrigerate them for up to 24 hours before baking. Season right before they go in the oven for the best flavor. This is also a great recipe for meal prepping for the week, the leftovers are just as good cold.
