08 - 1 tsp ground cumin
09 - 1 tsp smoked paprika
10 - 1/2 tsp garlic powder
11 - 1/2 tsp onion powder
12 - 1/4 tsp crushed red pepper flakes (optional)
13 - 1 tsp kosher salt
14 - 1/2 tsp freshly ground black pepper

15 - Warm flour or corn tortillas
16 - Chopped fresh cilantro
17 - Lime wedges
18 - Sour cream
19 - Salsa
20 - Guacamole
21 - Shredded cheese

# Steps:

01 - Preheat oven to 425°F. Line a large sheet pan with parchment paper or foil and set aside for easy cleanup.
02 - In a large mixing bowl whisk together olive oil, chili powder, ground cumin, smoked paprika, garlic powder, onion powder, crushed red pepper flakes (if using), kosher salt and black pepper until homogeneous.
03 - Add the sliced chicken, bell peppers and red onion to the bowl. Using tongs or gloved hands, toss thoroughly until all pieces are evenly coated in the spice oil.
04 - Spread the coated chicken and vegetables in a single, even layer on the prepared sheet pan, ensuring pieces are not overcrowded to promote browning.
05 - Bake on the middle rack for 22 to 25 minutes, turning once midway if desired, until chicken reaches 165°F and vegetables are tender with lightly charred edges.
06 - Remove the pan from the oven, squeeze fresh lime over the contents and sprinkle with chopped cilantro. For extra char, transfer to broiler for 2 to 3 minutes, watching carefully.
07 - Warm tortillas, divide the chicken and peppers among them, and offer toppings such as sour cream, salsa, guacamole and shredded cheese alongside for guests to customize.

# Expert Suggestions:

01 -
  • You get that restaurant-style fajita sizzle without standing over a stove or creating a mountain of dishes.
  • It’s endlessly customizable depending on what’s hiding in your vegetable drawer or which toppings you’re craving most.
02 -
  • If you crowd the pan, the chicken steams instead of roasting, and the peppers won’t char—spread it all out for those caramelized edges.
  • Letting the chicken and veggies marinate for even 15 minutes brightens the flavor and tenderizes the meat more than you’d expect.
03 -
  • Line your pan with parchment rather than foil to avoid sticking and for easiest cleanup.
  • Add a pinch of smoked paprika to your salsa or sour cream for an extra flavor boost that’s barely noticeable, but makes you crave another bite.
