Ingredients
- 1.5 lbs chicken breast, sliced into thin strips
- 3 large bell peppers (red, yellow, and green), sliced into strips
- 1 large red onion, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon chili powder
- 1 teaspoon ground cumin
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon lime juice
- Warm flour or corn tortillas for serving
- Optional toppings: Sour cream, avocado, cilantro, lime wedges
Directions
Step 1: Preparation
Preheat your oven to 425°F (220°C). While the oven heats up, slice the chicken breasts, bell peppers, and red onion into uniform thin strips. Place the chicken and vegetables directly onto a large, rimmed baking sheet. In a small bowl, whisk together the olive oil, lime juice, chili powder, cumin, garlic powder, smoked paprika, salt, and pepper.
Step 2: Cooking
Drizzle the spice and oil mixture over the chicken and vegetables. Use your hands or tongs to toss everything until evenly coated, then spread the mixture out into a single layer across the pan. Slide the baking sheet into the oven and roast for 15 minutes. For a slight char, you can turn on the broiler for the last 2 minutes of cooking, watching closely to prevent burning.
Step 3: Plating
Remove the pan from the oven and give everything a quick toss to distribute the juices. Warm your tortillas in a dry skillet or the microwave. Fill each tortilla with a generous portion of the chicken and pepper mixture. Top with fresh cilantro, a squeeze of lime, and your favorite toppings like sliced avocado or cool sour cream. Serve immediately while hot.
Expert Tips for Perfect Quick & Easy Chicken Fajitas Sheet Pan 20 Min
To ensure the best results, do not overcrowd your sheet pan. If the chicken and veggies are piled too high, they will steam instead of roast, and you will miss out on those delicious charred edges. If you have a lot of ingredients, use two pans. Also, make sure to cut your chicken and peppers into similar sizes so they cook at the same rate. Finally, use a high-quality chili powder for the best flavor profile.
Delicious Variations
You can easily swap the chicken for steak or shrimp. If using shrimp, reduce the cook time to about 8-10 minutes. For a vegetarian version, use thick slices of portobello mushrooms or extra bell peppers. If you like heat, toss in some sliced jalapeños or add a pinch of cayenne pepper to the spice mix. For a low-carb option, skip the tortillas and serve the fajita mixture over a bed of cauliflower rice or a fresh green salad.
Frequently Asked Questions
Can I use chicken thighs instead of breasts?
Yes! Chicken thighs are very juicy and work perfectly for this recipe. Just ensure they are boneless and skinless, and cut them into thin strips like you would with the breasts.

How do I prevent the tortillas from getting soggy?
The best way is to serve the chicken and vegetables directly from the pan rather than pre-filling the tortillas. This allows guests to control the amount of juice they include in their wrap.
Can I make this for meal prep?
Absolutely. This recipe is excellent for meal prep. Store the cooked chicken and vegetables in an airtight container for up to 4 days. Reheat in a skillet or microwave before serving.
What is the best way to warm the tortillas?
For the best flavor, char them slightly over an open gas flame for a few seconds or heat them in a dry cast-iron skillet until warm and pliable. You can also wrap a stack in damp paper towels and microwave for 30 seconds.
Is this recipe spicy?
As written, this recipe has a mild to medium heat. The chili powder provides flavor without intense heat. If you are sensitive to spice, reduce the chili powder by half. If you love heat, add red pepper flakes.
