Baked Chicken Fajitas
If you want an easy chicken fajitas recipe, this is it. The chicken, peppers, and onions are seasoned, tossed with oil, and baked together on a sheet pan. Serve in warm flour tortillas with your favorite toppings for a quick, healthy dinner everyone will enjoy. These sheet pan fajitas are especially helpful for picky eaters who may be more willing to try vegetables when mixed with savory seasoned chicken.
The recipe uses chicken breasts, but tenderloins or boneless thighs work just as well. Slice the protein into strips, cut the vegetables into similar-sized strips, season everything, and roast until the chicken is cooked through and the peppers are slightly charred.
These fajitas are versatile—use the filling for tacos, burrito bowls, salads, or simply serve with rice. Sheet pan chicken fajitas are a reliable go-to for fast, flavorful meals.
Key Ingredients
- Chicken – boneless, skinless chicken breasts are recommended, though tenderloins or thighs work well. Cut into 1″ strips; plan on about 1/4 lb per person.
- Bell Peppers – use a mix of red, orange, yellow and/or green for color and flavor.
- Onion – white, yellow, or red onion, sliced into strips.
- Seasoning – fajita or taco seasoning works great. Adjust spices to taste.
- Chili Powder – adds mild heat; increase or decrease to suit your preference.
- Tortillas – small flour tortillas are traditional, but corn or lettuce wraps are alternatives.
- Toppings – sour cream, shredded cheese, salsa, shredded lettuce, and fresh cilantro are all excellent choices.
How to Make Chicken Fajitas in the Oven
- Season the chicken. Place sliced chicken in a bowl and toss with oil, garlic, and the seasonings so each piece is evenly coated.
- Arrange on a sheet pan. Lightly spray a baking sheet and spread the chicken, peppers, and onions in a single layer for even roasting.
- Bake. Roast at 400°F (200°C) for 15–20 minutes, until the chicken is cooked through and vegetables have begun to brown at the edges.
- Serve. Warm the tortillas and assemble fajitas with your preferred toppings. Enjoy immediately.

Frequently Asked Questions
If meat is the main component, plan about 1/3 pound (around 150 g) of chicken per person. For fajitas served in tortillas with toppings, 1/4 pound (about 115 g) per person is usually sufficient. If you’re serving very hungry eaters, increase to 1/3 pound. Leftovers reheat well, so making a little extra can be convenient.
