These sheet pan chicken fajitas are all about bold flavor and easy cleanup. The chicken comes out tender, the veggies get a little caramelized around the edges, and everything soaks up that perfect blend of spices. Load it all into warm tortillas and you’re good to go.

- Fast: No marinating or extra steps and everything comes together on the pan. No extra dishes. Perfect when you want something quick but still homemade.

Easy Mexican inspired meals like these sheet pan fajitas and my Chicken Fajita Pasta are a go-to in my house. We love the bold flavors I love that cleanup is minimal! I make these sheet pan fajitas at least once a month and we save the leftovers for easy meal prep lunches for the rest of the week.

Ingredients and Substitutions
- Chicken breasts – Chicken thighs also work well if you want something juicier. Chicken thighs will take longer to cook.

- Yellow onion – Red or white onion will also work
- Olive oil – Any neutral cooking oil will work
- Chili powder – No substitutions
- Ground cumin – No substitutions
- Paprika – Smoked paprika adds a deeper flavor if you prefer
- Sea salt – Kosher salt works too
- Garlic powder – Fresh minced garlic can be used but the powder blends more evenly
- Onion powder – No substitutions
- Oregano – Dried Mexican oregano is great if you have it
- Cracked black pepper – Ground black or white pepper is fine
- Cayenne pepper – Leave it out if you want less heat
- Flour tortillas – Corn tortillas or low carb tortillas can be used

Mandy’s Top Tip
For extra flavor, let the chicken and veggies sit in the seasoning mix for ten to fifteen minutes before baking. It helps everything soak in and gives a little boost to the final dish.
Tips for Success
Even slices – Slice the chicken and veggies as evenly as you can so they cook at the same rate.
Avoid crowding – Spread everything out on the pan as evenly as possible. It’s ok if some things overlap slightly, but you want to avoid large piles in one area.
Flip halfway – Flip the chicken and veggies halfway through cooking for even browning.
Warm tortillas – Warm the tortillas before serving so they’re soft and pliable.
