15-Minute Sheet Pan Chicken Fajitas

By Ava Thorne
September 4, 2026

Okay, I need to talk about these fajitas because they have genuinely changed my weeknight dinner situation forever. One pan, one spice blend, fifteen minutes — and the result looks like something you'd pay $18 for at a restaurant. The colors alone? Absolutely unreal.

The trick is cutting everything thin and uniform so it cooks fast and gets those gorgeous caramelized edges. I crank the oven to 425°F and let the high heat do its thing — no sad steamed veggies, just proper char. And the fajita spice mix I use here is my go-to that I've been perfecting for two years. You will want to put it on literally everything.

Serve straight from the pan at the table with warm tortillas and all the toppings — sour cream, guac, fresh pico — and watch everyone lose their minds. This is the recipe I make when I need dinner on the table with zero effort and zero compromise on flavor. It never fails. Ever.

15-Minute Sheet Pan Chicken Fajitas

The easiest, most colorful fajitas of your life — juicy spiced chicken strips and charred bell peppers all on one pan, ready in 15 minutes flat. Weeknight dinner, totally unlocked.

Instructions

  1. 1

    Preheat oven to 425°F (220°C). Line a large rimmed sheet pan with foil and set aside.

  2. 2

    In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, black pepper, and cayenne. Mix well.

  3. 3

    Add chicken strips, sliced bell peppers, and red onion to the sheet pan. Drizzle with olive oil and sprinkle the spice mixture evenly over everything.

  4. 4

    Toss everything directly on the pan with your hands (or tongs) until every piece is fully coated in the spiced oil.

  5. 5

    Spread into a single even layer — this is key! Don't pile things up or they'll steam instead of char.

  6. 6

    Roast at 425°F for 10–12 minutes, until chicken is cooked through and the peppers have beautiful charred edges.

  7. 7

    Remove from oven and squeeze fresh lime juice over everything immediately.

  8. 8

    Serve straight from the pan with warm flour tortillas and all your favorite toppings — sour cream, guacamole, pico de gallo, and extra lime wedges.
