Ingredients
- 1½ lbs (≈680 g) boneless, skinless chicken breasts, sliced into thin strips
- 3 bell peppers (red, yellow, green), sliced into matchsticks
- 1 large onion, thinly sliced
- 2 Tbsp olive oil
- 1 Tbsp lime juice (about 1 lime)
- 1 tsp smoked paprika
- 1 tsp ground cumin
- ½ tsp chili powder
- ½ tsp garlic powder
- ¼ tsp onion powder
- ¼ tsp black pepper
- ½ tsp sea salt
- Warm flour or corn tortillas for serving
- Optional toppings: guacamole, sour cream, shredded cheese, fresh cilantro, lime wedges
Step‑by‑Step Instructions
- Preheat the oven to 425°F (220°C). Position a rack in the middle of the oven to ensure even cooking.
- Prepare the marinade: In a large bowl, whisk together olive oil, lime juice, smoked paprika, cumin, chili powder, garlic powder, onion powder, black pepper, and sea salt.
- Marinate the chicken: Add the sliced chicken to the bowl, tossing to coat evenly. Let it sit for 5‑7 minutes while you prep the vegetables.
- Slice the vegetables: Cut bell peppers into thin strips and slice the onion. Toss them in a drizzle of olive oil, a pinch of salt, and a sprinkle of the remaining spice blend.
- Arrange on a sheet pan: Spread the marinated chicken in a single layer on a large rimmed baking sheet. Add the seasoned peppers and onions around the chicken, ensuring everything is spaced out for proper caramelization.
- Roast for 12‑15 minutes, stirring halfway through, until the chicken is cooked through (internal temperature 165°F/74°C) and the vegetables are tender‑crisp with a light char.
- Finish with fresh lime: Remove the pan from the oven and squeeze an extra half‑lime over the top for a bright finish.
- Warm the tortillas: While the fajita mixture rests, wrap tortillas in foil and warm them in the oven for 3‑4 minutes, or heat them on a dry skillet for 30 seconds per side.
- Assemble: Spoon the chicken‑pepper mixture onto each tortilla, then add your favorite toppings—guacamole, cilantro, cheese, or a drizzle of sour cream.
- Serve immediately and enjoy the burst of flavor!
Pro tips & tricks
Maximize caramelization
Do not overcrowd the pan. If your sheet pan is small, split the mixture onto two pans. Space allows steam to escape, giving you those coveted charred edges.
Even cooking
Cut chicken and vegetables to uniform thickness (about ¼‑inch). This ensures they finish cooking at the same time, preventing dry chicken or under‑cooked peppers.
Temperature tip
A hot oven (425°F/220°C) creates a quick sear. If you prefer a gentler bake, lower to 400°F and add 3‑4 extra minutes.
Make ahead
Marinate the chicken up to 24 hours in the fridge. The flavors deepen, and you can simply dump the pre‑marinated strips onto the pan when ready.
Variations & substitutions
- Protein swaps: Use thinly sliced flank steak, shrimp, or firm tofu for a vegetarian twist.
- Spice level: Add ½ tsp cayenne pepper or a sliced jalapeño for extra heat.
- Low‑carb option: Serve over cauliflower rice or lettuce wraps instead of tortillas.
- Herb boost: Toss fresh chopped cilantro or parsley over the finished dish for a bright, herbaceous finish.
- Smoky depth: Replace smoked paprika with chipotle powder for a deeper smoky flavor.
- Sweet‑heat balance: Drizzle a little honey or agave nectar before roasting to create a caramelized glaze.
Storage tips
Refrigeration: Store leftover fajita mixture in an airtight container for up to 3 days. Reheat gently in a skillet over medium heat or in the microwave (covered) to retain moisture.
Freezing: Separate the chicken and vegetables from the tortillas, place them in a freezer‑safe bag, and freeze for up to 2 months. Thaw overnight in the fridge and re‑roast for 5‑7 minutes at 350°F (175°C).
Meal‑prep idea: Portion the cooked mixture into individual containers, add a small bag of shredded cheese, and keep tortillas in a separate zip‑lock. Assemble quickly at work for a flavorful lunch.
