Perfect for busy weeknights or casual gatherings, this recipe delivers big taste with little effort.
Ingredients
- 1 1/2 pounds boneless, skinless chicken breasts (about 2-3 breasts)
- 3 bell peppers (mixed colors: red, yellow, green), sliced into 1/2-inch strips
- 1 large yellow onion, sliced into 1/2-inch strips
- 3 tablespoons olive oil
- 1 1/2 teaspoons chili powder
- 1 teaspoon smoked paprika
- 1 teaspoon ground cumin
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon dried oregano
- 1/2 teaspoon kosher salt (plus more to taste)
- 1/4 teaspoon freshly ground black pepper
- 1 lime, cut into wedges
- 8 small flour or corn tortillas, for serving
- Optional toppings: chopped cilantro, sour cream, salsa, sliced avocado, shredded cheese
Instructions
- Preheat the oven: Set your oven to 425°F (218°C). Line a large rimmed baking sheet with parchment paper or foil for easier cleanup.
- Prepare the chicken and vegetables: Slice the chicken breasts into thin strips, about 1/2-inch wide and 2-3 inches long. Place the sliced chicken, bell peppers, and onion onto the prepared baking sheet.
- Make the seasoning blend: In a small bowl, combine the chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, salt, and black pepper. Stir to mix.
- Season and toss: Drizzle the olive oil over the chicken and vegetables. Sprinkle the seasoning blend evenly over everything. Use your hands or tongs to toss until all pieces are well coated and spread them out in an even layer on the baking sheet.
- Roast: Place the baking sheet in the preheated oven. Roast for 18-22 minutes, stirring halfway through, until the chicken is cooked through (internal temperature of 165°F/74°C) and the vegetables are tender with slightly charred edges.
- Warm tortillas: While the fajitas are roasting, wrap the tortillas in foil and place them in the oven for the last 5 minutes of cooking, or heat them in a dry skillet over medium heat until warm and pliable.
- Finish and serve: Remove the sheet pan from the oven. Squeeze fresh lime juice over the chicken and vegetables. Serve immediately with warm tortillas and your choice of toppings.
Tips
- Substitutions: Swap chicken breasts for boneless, skinless chicken thighs if you prefer juicier meat. For a vegetarian version, use sliced portobello mushrooms or extra-firm tofu instead of chicken.
- Don’t overcrowd the pan: Spread the ingredients in a single layer. If your pan is too crowded, the chicken and vegetables will steam instead of roast, leading to soggy results.
- Customize the spice level: Add 1/4 to 1/2 teaspoon of cayenne pepper or chipotle chili powder to the seasoning blend for extra heat.
- Meal prep: Slice the chicken and vegetables up to 24 hours in advance and store them in the refrigerator for an even quicker meal.
Serving Suggestions
Serve your sheet pan chicken fajitas family-style, letting everyone build their own fajitas with warm tortillas and a variety of toppings. Classic sides include Mexican rice, refried or black beans, and a crisp green salad. For a fresh touch, serve with pico de gallo, guacamole, or a squeeze of extra lime. If you’re looking for a low-carb option, serve the chicken and veggies over a bed of greens or in lettuce wraps.
Variations
- Steak Fajitas: Substitute sliced flank steak or sirloin for chicken, adjusting the roasting time to 10-12 minutes for medium-rare steak.
- Shrimp Fajitas: Use peeled, deveined shrimp instead of chicken and roast for just 8-10 minutes, or until the shrimp are pink and cooked through.
- Extra Veggies: Add sliced zucchini, mushrooms, or cherry tomatoes to the pan for more color and nutrition.
- Cheesy Fajitas: Sprinkle shredded Monterey Jack or cheddar cheese over the fajitas during the last 2 minutes of roasting for a melty finish.
- Low-Sodium: Reduce the salt and use homemade seasoning blends to better control sodium content.
Storage and Reheating
Store leftover chicken and vegetables in an airtight container in the refrigerator for up to 4 days. To reheat, spread the fajita mixture on a baking sheet and warm in a 350°F (177°C) oven for 8-10 minutes, or until heated through. Alternatively, reheat in a skillet over medium heat, stirring occasionally, until hot. For individual portions, the microwave works well—place fajitas on a microwave-safe plate, cover with a damp paper towel, and heat in 45-second bursts until warm. Store tortillas separately to prevent them from becoming soggy.
Frequently Asked Questions
- Can I use frozen chicken or vegetables?
It’s best to use fresh chicken and vegetables for optimal texture and flavor. If you use frozen, thaw thoroughly and pat dry before seasoning and roasting, as excess moisture can make the fajitas soggy. - How do I know when the chicken is cooked through?
Chicken is safe to eat when it reaches an internal temperature of 165°F (74°C). Use a digital meat thermometer to check the thickest pieces. The chicken should also be opaque and the juices should run clear. - Can I make these fajitas ahead of time?
Yes! You can slice and season the chicken and vegetables up to a day in advance. Store them in the fridge, then roast right before serving. Leftovers also reheat well for meal-prep lunches. - What kind of tortillas work best?
Both flour and corn tortillas are delicious with chicken fajitas. Flour tortillas are softer and more flexible, while corn tortillas offer a classic, slightly sweet flavor. Warm them before serving for best results. - How can I make this recipe dairy-free or gluten-free?
For dairy-free fajitas, omit any cheese or sour cream toppings. For gluten-free, use certified gluten-free corn tortillas and check that your spices are gluten-free. - Can I double the recipe for a crowd?
Absolutely! Use two sheet pans and rotate them halfway through roasting to ensure even cooking. Avoid overcrowding so everything roasts properly.
