Step-by-Step Overview

This recipe moves fast. First you preheat the oven and line a sheet pan.

Roast briefly, stir, then finish under the broiler to get those slightly charred edges. Finally, warm your tortillas and assemble with whatever toppings you love.

What You’ll Need

1 pound chicken breast tenders, cut into bite-size pieces, 1 red onion, thinly sliced, 1 green pepper, thinly sliced, 1 red pepper, thinly sliced, 1 yellow pepper, thinly sliced, 2 tablespoons olive oil, 1 tablespoon chili powder, 1 tablespoon cumin, 1 teaspoon garlic powder, 1 teaspoon paprika, 1 teaspoon dried oregano, 1/2 teaspoon onion powder, Kosher salt, Fresh cracked pepper

Notes and simple swaps:

Chicken thighs: swap for equal weight if you prefer richer flavor (adjust cook time by a few minutes).
Oil: avocado oil or light olive oil work well at high heat.
Spice adjustments: add 1/2–1 teaspoon cayenne for heat or 1 teaspoon smoked paprika for a deeper smoky note.
Gluten-free: use corn tortillas or lettuce wraps.

Step-by-Step Instructions

Preheat the oven to 400°F (200°C). Line a large baking sheet with parchment paper or foil for easy cleanup.
Arrange the bite-size chicken pieces, thinly sliced red onion, and sliced green, red, and yellow peppers in a single layer across the sheet pan.
Drizzle the 2 tablespoons of olive oil over the chicken and vegetables.
Sprinkle the chili powder, cumin, garlic powder, paprika, dried oregano, onion powder, Kosher salt, and fresh cracked pepper evenly over everything.
Toss directly on the pan (or use a spatula) to coat the chicken and veggies thoroughly with oil and spices.
Bake for 10 minutes. Pull the pan, stir to redistribute items for even cooking, then return to the oven.
Bake an additional 5 minutes.
Switch the oven to Broil and broil for 2–3 minutes, watching closely, until the edges have nice charred spots.
Serve the chicken and peppers on warm flour tortillas and add your favorite toppings.

Best Ways to Enjoy It

Serve these fajitas straight from the sheet pan into warm flour tortillas with classics like cilantro, lime wedges, sliced avocado or guacamole, sour cream or crema, shredded cheese, and pico de gallo. For a lighter bowl, skip the tortillas and serve over cilantro-lime rice or a bed of greens with black beans and corn.

Pair the meal with a crisp cerveza or a bright lime margarita for adults. If you want sides, a simple charred corn salad or Mexican street corn-style salad complements the fajita flavors. For a different meal plan, serve alongside a coconut rice recipe such as the one in pan-fried curry chicken posts to mix cuisines on a themed night.

Storage and Reheating Tips

Refrigerator: Store leftovers in an airtight container for 3–4 days.
Freezer: For longer storage, freeze cooked fajita filling in a sealed container for up to 3 months. Thaw overnight in the fridge before reheating.
Reheat: Reheat gently in a skillet over medium heat to revive char and texture (2–4 minutes). Alternatively, spread on a baking sheet and warm in a 350°F oven for 8–10 minutes. Microwave if needed, but the skillet or oven gives better texture.
Safety: Reheat until the chicken reaches 165°F internally.

Helpful Cooking Tips

Cut uniformly: Make sure chicken pieces and pepper strips are similar in size so everything cooks at the same rate.
Single layer matters: Crowding the pan steams the vegetables. Use two pans if necessary.
Watch the broil: Broiling takes seconds—stay by the oven so you get char without burning.
Rest briefly: Let the chicken rest 2 minutes after roasting before assembling to lock in juices.
Make it ahead: You can mix the spice blend and cut veggies a day ahead to speed evening assembly. For more simple chicken tips, see simple pan-fried chicken techniques.

Recipe Variations

Steak fajitas: Swap chicken for thin-sliced flank steak; adjust broil time to desired doneness.
Shrimp fajitas: Use large shrimp, reduce initial baking to 6–8 minutes, then broil 1–2 minutes.
Vegetarian: Omit chicken and add sliced mushrooms or cauliflower florets; roast until tender and slightly crisp.
Smoky chipotle: Add 1–2 teaspoons chipotle in adobo (minced) to the spice mix for a smoky heat.
Low-carb: Serve on romaine leaves or over cauliflower rice.
Meal-prep bowls: Layer cooked fajita mix with rice, black beans, and avocado in meal containers for up to 4 days.

Frequently Asked Questions

Q: Can I use chicken thighs instead of breast tenders?
A: Yes. Bone-free, skinless thighs add more fat and flavor. Cut into similar-sized pieces and watch for slightly longer cook time — check for 165°F internal temperature.

Q: How spicy is this recipe and how can I adjust it?
A: This base recipe is mildly spiced. To increase heat, add cayenne or crushed red pepper. To mellow it, reduce the chili powder or add a touch of brown sugar to balance flavors.

Q: Can I prep this ahead for a busy weeknight?
A: Absolutely. Slice the peppers and onions and mix the spice blend a day ahead. Store components separately in the fridge and toss everything together on the pan right before baking.

Q: What’s the best way to reheat without drying the chicken?
A: Reheat in a skillet over medium heat with a splash of water or oil to keep the chicken moist, or warm in the oven on a baking sheet at 350°F for 8–10 minutes.
