Forget fussing with separate pans. This easy sheet pan dinner loads up a single tray with all the good stuff for juicy, zesty fajitas and only a few dishes to wash. The bold flavors pack a punch and cleanup is a breeze.
For busy nights when I just can't deal with anything fancy, fajitas on a sheet pan save the day. My crew even likes these more than takeout—roasting in the oven packs in flavor you just can't get in a skillet.
Tasty Key Ingredients
- Flour tortillas: The perfect way to pile on those flavorful fillings
- Cumin: That classic earthy kick you expect from fajitas
- Bell peppers trio: Bright, sweet, and colorful to mix things up
- Canola or vegetable oil: Helps keep everything from sticking while roasting
- Yellow onion: Sweetens and softens in the oven, packing every bite with flavor
- Paprika: Brings a gentle sweet heat and gorgeous color
- Fresh garlic: Big flavor—way better than just using powder
- Chili powder: The flavor backbone you'll taste in every bite
- Cilantro: Gives that pop of fresh green taste
- Fresh lime juice: Tangy zip makes all those flavors brighter
- Dried oregano: Adds a gentle herbal hint
- Boneless skinless chicken breasts: Slice it thin for juicy, tender bites that cook up fast
- Onion and garlic powders: Quick and easy for bumping up taste
Simple Step-by-Step
- Final Touches and Serve:
- Squeeze a fresh lime all over the hot pan. Sprinkle with chopped cilantro right before serving. Fill tortillas with the delicious mix and pass around your favorite toppings for a build-your-own dinner.
- Sizzle in the Oven:
- Roast the whole pan at 425°F, about 15 minutes does the trick for juicy chicken and nicely browned veggies. Wrap tortillas in foil and warm them in the oven at the end so everything’s hot when you’re ready to eat.
- Season and Spread:
- Generously sprinkle seasoning over chicken, then the rest over veggies. Scatter minced garlic mostly over the chicken. Drizzle with oil and toss everything so it’s all coated. Make sure it’s spread out in one layer on the pan for best results.
- Mix Up Your Spices:
- Dump all the spices for seasoning into a little bowl and give them a good stir. Homemade always tastes better than packets and you can keep the salt just how you like. The cayenne gives just a gentle warmth, not a fiery kick.
- Get Chicken and Veggies Ready:
- Slice the chicken across the grain into half-inch wide strips so it stays tender. Cut peppers and onions to match for even cooking. Spread out the veggies on the pan and lay the chicken strips on top.
- Grease That Pan:
- Spray a roomy sheet pan well so nothing sticks. A pan with high enough sides keeps all those tasty juices from spilling everywhere. This trick saves on cleanup and gives you great browning.

Getting that spice blend just right took a bunch of tries, but wow, it was worth it. Even my picky kid who doesn't love spicy food goes wild for these, and my Texan husband swears they're on par with the best he's had. Roasting in the oven just makes all the flavors stronger and better.
Leftovers & Reheating
Pop any leftover fajita filling in a sealed container in the fridge. It’ll stay good for 4 days. Stash tortillas separately so they don’t get soggy. Toss fillings in a skillet to warm ‘em up or zap them in the microwave for a couple minutes. The flavors actually meld and get even better by the next day.
Plan Ahead Tips
Save time later by cutting all your veggies and chicken up to a day early—just keep them in separate containers in the fridge. The spice mix will keep for weeks in an airtight jar. Want to freeze? Put your raw, seasoned chicken and veggies in a bag and freeze for up to 3 months.
Make It Your Way
Switch up this meal for how you eat or what you have. Want it veggie? Try black beans, mushrooms, or sweet potato instead of chicken. Skip the tortillas and load the mix on lettuce or cauliflower rice for fewer carbs. Turn up or tone down the heat by playing with the cayenne.
How to Serve
Set up a fun fajita bar and let everyone build their plate. Guac, cheese, pico de gallo, sliced jalapeños, and sour cream make great add-ons. For a full dinner spread, offer Mexican rice and beans too. Just looking for a light bite? Pair with a simple green salad splashed with lime dressing.
