How To Make Sheet Pan Chicken Fajitas

1. Preheat the oven to 425°F. Line a large sheet pan with parchment paper.
2. Make the Fajita Seasoning – In a small bowl mix together: chili powder, paprika, onion powder, garlic powder, cumin, cayenne, sugar, and salt.
3. Prep the Chicken and Vegetables. Slice the chicken breast into thin strips. Cut the onions and bell peppers into thin strips.

4. Season. Drizzle the olive oil over everything. Sprinkle the fajita seasoning over the top and toss until the chicken and vegetables are well coated. Spread everything out evenly in a single layer.

Expert Tips

Slice Chicken and Veggies Evenly: Make sure everything is similar in size to ensure even cooking.
Spread Ingredients in Single Layer: This allows everything to get nicely charred. Don’t overcrowd the pan, or the chicken and veggies will steam.
Use a Large Sheet Pan: Using a large surface space gives you more room to spread out. Don’t cram everything onto a small pan. Use 2 sheet pans if you need to.
Broil At The End: Use the ‘broil’ setting during the last few minutes of cooking for a nice final char. But keep an eye on them so nothing burns!
Serve With Warm Tortillas: This makes all the difference. Warm them in a pan on the stovetop or wrap in damp paper towels then microwave for a few seconds.
Try Other Proteins and Add Extra Veggies: Swap in strips of steak or shrimp for chicken, or skip the meat all together and add in extra veggies for a vegetarian version.

What To Serve With Chicken Fajitas

Warm Tortillas: A classic choice and a popular favorite — corn or flour work great.
Mexican Rice: Pairs well with the zesty fajita flavoring.
Cilantro Lime Rice: Simple and satisfying.
Refried Beans or Black Beans: Another classic side, for more protein.
Mexican Street Corn Dip: Flavor-packed and delicious for traditional elote vibes.
Tortilla Chips with Salsa or Guacamole: For a classic restaurant pairing.

Storage

Store leftover fajitas in an airtight container in the fridge for 3-5 days. Reheat on a sheet pan in the oven, covered, until warmed through. Serve with fresh tortillas and toppings of your choice.

This is a great make-ahead meal, too. Prep the chicken, veggies and seasoning blend in advance, and either store in the fridge or freezer, until you’re ready to assemble and cook. Thaw overnight in the fridge, if prepping from frozen. Then, cook according to the instructions.

FAQs

Can I use chicken thighs instead of chicken breasts?

Absolutely. Thighs are super flavorful and juicy and would make delicious fajitas. Use boneless skinless thighs for ease.

What temperature should fajitas cook at in the oven?

A high heat like 400° or 425° will give you the best, crisped up, results. You can bake them at a lower temperature, but they’ll take longer to cook and won’t have as much browning.

How do I keep the vegetables from getting soggy?

Make sure the veggies and chicken are patted dry before adding to the pan, avoid overcrowding the pan, and place everything in a single layer. Don’t cram or pile on layers – this will cause steaming instead of browning.

Can I use store-bought fajita seasoning?

Sure. Use your favorite brand and keep it on hand for future fajita and Mexican-inspired meals.
