Why We Love Sheet Pan Chicken Fajitas

What’s not to love about an easy single-sheet pan meal of slightly spicy chicken, peppers, and onions? The next time you’re looking for a simple but flavorful weeknight meal for taco Tuesday (or on busy weeknights), or a great way to feed a crowd, check out these sheet pan chicken fajitas.

• Customizable – Oven-baked fajitas can be spicy or mild, folded into tortillas or used as a nacho topper, and are the perfect canvas for your creativity in terms of toppings. 
• Easy – What makes pan fajitas such an easy meal to make is that there’s so little preparation involved — just mix all of the ingredients together and pop the pan in the oven. We might admit, though, that the best part (outside of eating them, of course) is the cleanup – since you’re baking the whole meal on one pan, washing dishes afterward is a cinch.
• Versatile – Sheet pan chicken fajitas are as fun for a party as they are for weeknights. They’re also perfect for meal prep.

Ingredients for Chicken Pan Fajitas

A few simple ingredients are all you need to make the best sheet pan chicken fajitas. You’ll need to grab a mixing bowl, a wooden spoon, and a rimmed large sheet pan.

For specific amounts, please refer to the printable recipe card at the bottom of the post.

• Boneless chicken breasts – The word “fajita” loosely translates to “little belt.” Keep this in mind as you are slicing the chicken into thin strips. 
• Bell peppers (red, orange, and yellow) –  Slice the peppers into a size that’s similar to the chicken so that they cook evenly.
• White onion – Slice the onion into long, thin slices.
• Olive oil – Use good quality olive oil for the best flavor.
• Chili powder – Brings mild to moderate spice to the chicken fajitas, depending on how much cayenne pepper is in the mix. Feel free to increase or decrease the amount depending on your palate. Or make your own chili seasoning to use, that way you’re in control more.
• Red pepper flakes – turn up the heat quickly, so add a pinch to ¼ teaspoon increments. 
• Garlic powder – If you’re a fan of garlic, feel free to increase the amount as much as you choose.
• Cumin – This spice imparts an earthy flavor to the dish.

Notes and Tips for the Best One Pan Chicken Fajitas

You’re going to love these simple fajitas just the way they are but there are a few easy ways to make sure they’re as quick to make, and as satisfying, as possible.

• If you want to make these oven baked fajitas ahead of time, coat them with the oil and season them, then refrigerate the uncooked ingredients in an airtight container or zip-top bag for up to 24 hours. 
• While you could cook these on the stovetop we prefer roasting the fajitas in the oven so that the vegetables soften perfectly and get a nice, light char, and the chicken cooks evenly, leaving it juicy and tender.
• Serve these hot and fresh out of the oven, especially if adding cheese on top.

Variations on Easy Chicken Fajitas

This is a great recipe for chicken fajitas but you can make your own additions, too.

• Heat – Increase the spiciness of these fajitas by adding more of the spices that are already in the recipe or adding hot sauce. You can also use black pepper.
• Peppers – Add some jalapenos for added flavor and flair. For even more heat, try spicier peppers. 
• Red onions – Try using red onions instead for more color.
• Lettuce – Instead of using traditional tortillas, try using lettuce wraps instead.
• Protein – Use beef, seafood, or plant-based alternatives in place of chicken.

Serving Suggestions

• Warm tortillas – Warm flour tortillas or corn tortillas are perfect to fill with the chicken and peppers.
• Tortilla chips – Serve tortilla chips on the side.
• Dips and sauces – Serve salsa, sour cream, queso dip, pico de gallo, or guacamole in a small bowl on the side to add on top, or choose your own favorite toppings.
• Salad – Serve a simple green salad to have with the meat or serve the fajita filling over top of the greens. This is a great way to make these fajitas low-carb.
• Crunch- Cabbage or slaw mix is a great way to add some crunch to oven-baked fajitas.
• Lime wedges – Squeeze fresh lime juice over the fajitas for a fresh, bright flavor. 
• Fresh cilantro – Garnish the fajitas with chopped cilantro.
