Step-by-Step Instructions for Sheet Pan Chicken Fajitas
Preheat the Oven
Preheat your oven to 400 degrees Fahrenheit. This step is important so the chicken and vegetables start cooking right away when placed inside. A hot oven helps the ingredients roast instead of steam, which gives better flavor and texture.
Prepare and Slice the Ingredients
Place the chicken breasts on a cutting board and slice them into thin strips. Try to keep the size fairly even so the chicken cooks at the same rate.
Slice the bell peppers into long strips. Remove the seeds and inner white parts before slicing. Cut the onion into thin slices as well. Keeping all vegetables similar in size helps them cook evenly.
Add Ingredients to the Sheet Pan

Place the sliced chicken, peppers, and onions onto a large sheet pan. Use a pan that is big enough so everything can spread out. If the pan is too crowded, the vegetables will release moisture and steam instead of roast.
Add Oil and Seasoning

Drizzle the olive oil over the chicken and vegetables. Make sure the oil is spread across most of the surface so everything cooks evenly.
Sprinkle the chili powder, paprika, cumin, garlic powder, onion powder, salt, and black pepper over the mixture. Try to distribute the spices across the pan instead of dumping them in one spot.
Mix Everything Well

Use clean hands or a large spoon to mix everything directly on the pan. Turn the chicken and vegetables several times to coat them fully with oil and seasoning.
Make sure the spices are evenly spread so every bite has flavor.
Spread Ingredients Evenly
Spread the chicken and vegetables into a single layer across the pan. Try not to stack pieces on top of each other.
Leaving space between the pieces allows heat to circulate, which helps the edges get slightly roasted and adds more flavor.
Bake the Fajitas
Place the sheet pan in the preheated oven. Bake for 20 to 25 minutes.
Halfway through cooking, remove the pan and gently stir the ingredients. This helps everything cook evenly and prevents sticking. Return the pan to the oven to finish cooking.
Check for Doneness
The chicken should be fully cooked with no pink inside, and the vegetables should be soft with slightly browned edges. If needed, cook for an additional 3 to 5 minutes.
Add Lime Juice and Serve

Remove the pan from the oven and squeeze fresh lime juice over the hot fajitas. This adds brightness and fresh flavor.
Serve immediately with warm tortillas. Add your favorite toppings as desired.
