When I'm craving fajitas but don't want to stand over the stove, this Sheet Pan Chicken Fajitas recipe is my go-to. Tender chicken, caramelized peppers and onions, and smoky spices all roast together in about 20 minutes, giving you a bold, colorful dinner with minimal effort and only one pan to wash!

Kristen's Keys for Sheet Pan Fajitas
These are the small details that make a big impact in the overall results.
- Slice with care. Thin, even strips (about ¼ inch for veggies, ½ inch for chicken) ensure everything cooks at the same rate and that your chicken will cook in the time it takes for the peppers and onions to soften and caramelize.
- Don't overcrowd the pan. Spread everything out in a single layer. If it's piled up too high, it will steam instead of roast and you'll miss those lightly charred edges that bring the flavor. It is better to use two sheet pans than overcrowd one.
- High heat matters (425°F). This isn't just to speed up the cook time. That higher temp helps the chicken cook quickly and gives the veggies that slight caramelization without turning mushy.
- Finish with lime and cilantro at the end. Both will give the fajita mixture a fresh, bright finish that makes it feel like you worked harder than you actually did.
Notes on Ingredients
- Chicken: The timing is based on using boneless, skinless chicken breasts. If you want to use chicken thighs, you will want to cut the thighs into slightly thinner strips, so that they cook in the time the peppers and onions cook.
- Fajita Seasoning: A homemade blend made with chili powder, cumin, smoked paprika, garlic powder, onion powder, kosher salt, and cayenne pepper.
- Bell Peppers: Red, yellow, or orange peppers lend sweetness to the fajitas, while green bell peppers add fresh, crisp flavor. Use a combination or what you personally like (or have on hand).
- Onion: A yellow or white onion is best here, as it becomes slightly sweet as it roasts.
- Lime: Use both the zest and juice to finish with bright, zesty flavor.
- Cilantro: Optional, omit if you don't care for it.
- Extra Virgin Olive Oil: To help the seasonings adhere to the chicken and veggies and promote browning.
How to Make Chicken Fajitas Using a Sheet Pan
Slice, season, roast, and serve.
Step One: Prep the Chicken and Veggies
Pat the chicken dry, then slice into thin, even strips against the grain. For the peppers, remove the stem, seeds and ribs, then slice into ¼-inch strips. Peel and slice the onions into ¼ -inch slices as well.
Step Two: Season
Add the sliced chicken, peppers, and onions to a greased sheet pan. Drizzle with additional oil and fajita seasoning and toss well to coat. I find using your hands works best here.
Step Three: Roast
Spread everything out into a single layer (its okay if SLIGHT overlap) then transfer to the oven. Bake for 8 minutes, flip and continue cook for 8-10 minutes, or until the chicken is cooked through and the peppers and onions softened and slightly caramelized.
Step Four: Finish with Flavor
Zest and juice the lime right over the mixture on the sheet pan. Add the cilantro (if using) and toss together.
Step Five: Serve
Pile into warm tortillas with your favorite toppings, or skip the tortillas and serve over rice (Instant Pot cilantro rice is fabulous here). And dinner is done!
Recipe Modifications
- Make it Low-Carb: Skip tortillas and serve in lettuce cups or over cauliflower rice.
- Dial Down the Spice: Omit cayenne and use regular paprika instead of smoked for sensitive eaters.
- Add More Veggies: Mushrooms or zucchini work well here. Just keep slices similar in size.
- Use Chicken Thighs: Slice into a bit thinner strips (¼ to ⅓-inch thick strips) as chicken thighs are best cooked to an internal temperature of 180-185°F, rather than 165°F.
Sheet Pan Chicken Fajitas is one of those meals that checks every box: fast, flavorful, and flexible. And on nights when dinner feels like one more thing on an already full plate, having a recipe like this in your back pocket makes all the difference. Enjoy!

I made this for dinner tonight and we absolutely loved it. The flavor is amazing! This was even better than the chicken fajitas I’ve had at our favorite Mexican restaurant. We had this with refried beans on the side which I make from your instant pot recipe. They are delicious as well. Much better than canned. I’ll definitely be making this often.
YAY! I love hearing this was deemed better than your favorite restaurant and will be on repeat. I also appreciate you taking the time to leave a review.
Turned out delicious! My whole family enjoyed it. Thank you!
Thanks for sharing, Kayla! I love hearing you all enjoyed!
