Sheet Pan Chicken Fajita Recipe

Prep time: 15 minutes 
Cook time: 30-35 minutes 
Servings: about 12 tortillas 

Ingredients: 

• 2.5 lbs chicken, diced 
• 1 red bell pepper, sliced 
• 1 yellow bell pepper, sliced 
• 1 orange bell pepper, sliced 
• 1 red onion, sliced 
• ½ tsp paprika 
• ½ tsp garlic powder 
• ½ tsp onion powder 
• ½ tsp Mexican chili powder 
• ½ tsp dried oregano 
• ½ tsp cumin 
• 1 tsp salt, or to taste 
• 1 tsp black pepper, or to taste 
• 2 garlic cloves, minced 
• 1 bunch cilantro, chopped 
• 2 tbsp olive oil 
• 2 tbsp sour cream, for topping 
• 1 avocado, diced, for topping 
• 1 cup mozzarella, shredded, for topping 
• 1 lime, juiced, for topping 
• 12 tortillas (e.g., flour tortillas) 

Instructions: 

1. Preheat the Oven: Preheat your oven to 375 degrees Fahrenheit 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 to the bowl. Mix until well combined. Then add the minced garlic, sliced red, yellow, and orange bell peppers, and sliced red onion. Mix everything together until the chicken and veggies are evenly coated with the spices 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 veggies evenly across the sheet pan, ensuring they are in a single layer. This will help them cook evenly. 
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 and starts to develop a delicious brown color. Make sure to check the chicken for doneness, as cooking times may vary slightly depending on your oven. 
5. Assemble Your Fajitas: Once your chicken fajitas are cooked to perfection, it’s time to assemble your meal. Warm your tortillas according to package instructions or personal preference. 
6. Toppings and Serving: Place a generous portion of the cooked chicken and veggie mixture onto each tortilla. Squeeze fresh lime juice over the filling, add diced avocado, a dollop of sour cream, a sprinkle of shredded mozzarella, and a garnish of chopped cilantro.
