How to Make Sheet Pan Fajitas

Okay, let’s keep this tight and simple. No fancy chef talk. You start by cutting up some chicken breast (or thighs if you like extra juicy, I don’t judge!). Toss it in a big bowl with sliced bell peppers, maybe an onion, and a solid splash of olive oil. Now the fun part: the fajita seasoning. You can use that store-bought packet or blend up your own with chili powder, cumin, garlic powder, salt, and smoked paprika if you’re feelin’ chefy.

Spread everything on a rimmed baking sheet (important, seriously, you don’t want drips everywhere) and cook at 425°F for about 20-25 minutes. Flip once if you remember, but if not, trust me, everyone will survive. While it’s roasting, you can throw your tortillas in foil right alongside for the last few minutes—super pro move, I swear.

Toppings for Chicken Fajitas

What’s a fajita without a little razzle-dazzle on top? I’ve tried every combo under the sun and, honestly, I think it’s the extras that turn good Sheet Pan Chicken Fajitas into a full-blown, five-star restaurant plate. Sour cream, absolutely. Sliced avocado or a dollop of guac, yes please. Salsa or pico de gallo if you’re feeling fancy, and don’t even get me started on shredded sharp cheddar. Some folks swear by pickled onions—they add some zip that’ll wake up your taste buds. And if you’re on a low-carb kick, just skip the tortilla and pile all the toppings on a big fat lettuce leaf. Pure joy.

Make Ahead and Freezing Instructions

Nobody, and I mean nobody, wants to fuss over dinner every single night. Here’s how I skate through: Prep your Sheet Pan Chicken Fajitas components ahead. Toss your chicken, peppers, and onions in seasoning the night before. Toss them in a zipped-up bag or an airtight container in the fridge. When you’re ready, just dump everything onto the sheet pan and roast. Super chill.

If you’re playing the long game, these actually freeze surprisingly well. Put your marinated chicken and veggies in a freezer bag, squeeze out the air, and stack flat. Pop it in the freezer and you’ve basically got a DIY meal kit for next week (or the week after, or whenever the chaos hits). Just thaw overnight in the fridge, then roast as usual. It practically does the work for you.

Storage and Reheating

Look, leftovers are the best part, aren’t they? Slide those fajitas into an airtight container and stick it in the fridge. They’ll keep for about three, maybe four days. When you’re ready to reheat, I find that a quick zap in the microwave works, but if you’ve got a smidge more time, tossing them back on a baking sheet and warming them in the oven at 350°F keeps the texture peppy. Oh, and keep tortillas separate, y’all—they can get rubbery if you reheat them with the filling.

Want to stretch it? Pile your leftovers into a salad, a quesadilla, or even scramble into some eggs in the morning. Fajita breakfast—yeah, I said it. You’ll thank me.

Common Questions

Q: Can I use beef or shrimp instead of chicken?
Absolutely! Beef strips or shrimp both work. Just cut them similar-sized and adjust cook time a bit. Shrimp will need less time so keep an eye.

Q: How spicy are these fajitas?
It’s up to you! Add extra chili powder or a jalapeño in the mix if you like heat.

Q: What’s the best way to keep the chicken juicy?
Don’t overcook it. Pull it out as soon as the edges start to brown and the pieces are cooked through.

Q: Are these good for meal prep?
Totally. Cook a double batch and use the leftovers for lunches or quick dinners through the week.

Q: Can I add other veggies?
Of course! Zucchini, mushrooms, even sweet potatoes (cut small) are great roasted with the mix.
