How to Make This Recipe
1. Preheat the oven
Preheat your oven to 375°F to ensure it’s ready when your fajitas are prepared.
2. Prepare the chicken and veggies
In a large mixing bowl, add the diced chicken, olive oil, paprika, garlic powder, onion powder, Mexican chili powder, dried oregano, cumin, salt, and black pepper. Mix well until all the chicken is evenly coated with the seasonings.
Add the minced garlic, sliced red, yellow, and orange bell peppers, and sliced red onion to the bowl. Toss everything together until the chicken and vegetables are well coated in the spice mixture and oil.
3. Arrange on a sheet pan
Prepare a sheet pan by lining it with parchment paper or lightly greasing it.
Spread the seasoned chicken and vegetables evenly across the sheet pan, ensuring they form a single layer. This ensures they roast evenly and develop a nice brown color.
4. Bake the fajitas
Place the sheet pan in the preheated oven and bake for 30–35 minutes, or until the chicken is fully cooked (the internal temperature should reach 165°F) and has become slightly browned.
You may want to stir the mixture halfway through the cooking time to ensure even roasting.
5. Warm the tortillas
While the chicken and vegetables are roasting, warm your tortillas according to the package instructions or by lightly toasting them on a dry skillet for a minute on each side.
6. Assemble the fajitas
Once your chicken and veggies are done, remove the sheet pan from the oven. Place a generous portion of the chicken and veggie mixture onto each tortilla.
7. Toppings and serving
Top the fajitas with a squeeze of fresh lime juice, diced avocado, a dollop of sour cream, a sprinkle of shredded mozzarella, and a garnish of chopped cilantro.
Serve immediately and enjoy.
These Sheet Pan Chicken Fajitas are perfect for a casual meal or party. Serve them with side dishes like rice, beans, or a fresh salad. You can also set up a fajita bar with additional toppings, such as sliced jalapeños, salsa, guacamole, or pickled onions, so your guests can customize their own fajitas.

Substitutions and Variations
- No chicken? Try diced tofu or mushrooms for a vegetarian version.

How to Store and Freeze
Refrigerate
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the oven at 300°F until warmed through, or in the microwave.
Freeze
Cool the cooked chicken and vegetables completely before transferring to a freezer-safe container. Freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Make ahead
You can slice the vegetables and chicken and toss them in the oil and spices a day ahead. Store covered in the fridge and bake just before serving.
Expert Tips

- Don’t skip the lime: The acid brightens all the savory flavors.
- Double the recipe: It stores and reheats well for lunch the next day.
- Customize toppings: Everyone can make their fajitas just the way they like them.
- Add fresh cilantro last: It keeps its flavor and adds a burst of green at the end.
