• Onion – Sliced and roasted to bring a mild, caramelized sweetness to the dish.
• Chili Powder – Provides a warm, smoky flavor with a hint of spice.

Kitchen Tools You Need to Make Sheet Pan Chicken Fajitas

• Non-Stick Baking Sheet – Essential for even roasting and easy cleanup.
• Large Bowl – Great for mixing the chicken, veggies, and marinade all together.
• Measuring Spoons – For accurate measurements of the marinade ingredients.
• Whisk – To combine the olive oil, lime juice, and chili powder smoothly.

How To Make Chicken Fajita Marinade

To make this chicken fajita recipe even more fantastic, I put together this quick and simple marinade to really give the chicken and veggies a ton of great flavor.

For this marinade, you will need:

• Olive oil
• Lime juice
• Chili powder

Whisk together all three of the ingredients mentioned above into a cup.

In a large bowl, combine the chicken breasts along with the chopped bell peppers and onion slices. Pour the olive oil marinade over the chicken and veggies and toss everything together until it’s all combined.

If you want (or have the time), let the fajitas marinate on the counter for 30 minutes or in the refrigerator overnight. But, if you don’t have the time or want to cook right away, go ahead and skip the marinating!

How To Make Chicken Fajitas In The Oven

Preheat the oven to 425 degrees and line a non-stick baking sheet with parchment paper.

After the chicken has been marinated, spread the chicken fajitas and vegetables on a baking sheet in a single layer. Make sure to not overcrowd the pan.

Place the sheet pan into the oven and bake the chicken fajitas in the oven on the top shelf. After 15 minutes, switch the oven temperature to broil and cook for an additional 5 minutes to get a little color and crispiness.

What To Serve With Chicken Fajitas

So, there are a couple of different ways you can serve this Mexican chicken dish.

You can go the traditional route and serve the chicken fajitas with some:

• Mexican street corn salad
• Fresh pico de gallo salsa
• Easy homemade guacamole
• Homemade Mexican flour tortillas
• Instant Pot cilantro lime rice

If you want to serve this chicken dish in a different way, you can serve it with some baked pasta, spicy chili sauce, and melted cheese! This is absolutely delicious!

Looking for something low carb? I highly recommend serving these chicken fajitas with a side of cauliflower rice or added to a bed of spring lettuce salad.

Tips for Success

• Cut Evenly for Quick Cooking: When slicing the chicken, peppers, and onions, try to keep everything a similar thickness. This helps everything cook evenly and avoids overcooked or undercooked pieces.
• Marinate for Extra Flavor: If you have the time, marinate the chicken and veggies for at least 30 minutes or even overnight in the refrigerator. This step allows the chili-lime flavors to penetrate deeply, making each bite more flavorful.
• Avoid Overcrowding the Pan: Spread the ingredients in a single layer on the baking sheet. If the pan is too crowded, the veggies and chicken may steam instead of roast, and you’ll miss out on that delicious caramelized edge.
• Switch to Broil for a Charred Finish: Broiling in the last 5 minutes gives the fajitas a nice char and crispy texture, just like a grill. Keep an eye on it during this step to avoid burning.
• Serve Immediately for Best Texture: These fajitas are best served hot right out of the oven. This way, the veggies stay crisp-tender, and the chicken is juicy.

Variations and Substitutions

• Switch Up the Protein: If you’re not in the mood for chicken, try using shrimp or thinly sliced beef instead. Shrimp cooks faster, so adjust the baking time accordingly, and for beef, you can use a quick broil to keep it tender.
• Make It Spicier: Add a little kick by including cayenne pepper or red pepper flakes in the marinade. You can also serve the fajitas with sliced jalapeños or a drizzle of hot sauce.
• Add More Veggies: Customize the veggie mix by adding sliced zucchini, mushrooms, or even cherry tomatoes. These will add variety in flavor and texture, and you can use up any veggies you have on hand.
• Try Different Seasonings: Instead of just chili powder, add a blend of spices like cumin, smoked paprika, and garlic powder for extra depth. This combination brings a smoky, savory flavor that complements the lime perfectly.
• Low-Carb Wrap Alternatives: If you want to keep it low-carb, serve the fajitas in lettuce wraps or over a salad. Romaine or butter lettuce leaves work well for holding the fajita mixture, keeping it light and fresh.

Storage and Reheating

• Storage: Place any leftover chicken fajitas in an airtight container and store in the refrigerator for up to 3 days. If you’re planning on freezing, transfer the cooked fajitas to a freezer-safe container and store for up to 2 months.
• Reheating: To reheat, spread the fajitas on a baking sheet and warm in the oven at 350°F for about 10 minutes, or until heated through. Alternatively, you can reheat in a skillet over medium heat for a few minutes, stirring occasionally, to keep the vegetables and chicken tender.
• Microwave Option: For a quicker option, microwave leftovers in a microwave-safe dish in 30-second increments, stirring between each, until warm. Keep in mind that this method may soften the veggies more than other reheating methods.

Frequently Asked Questions

Can I use chicken thighs instead of chicken breasts?

Yes! Chicken thighs are a great substitute for chicken breasts in this recipe and tend to be juicier. Just make sure to slice them into thin strips for even cooking.

What’s the best way to keep the fajitas warm for serving?

If you’re serving these for a crowd, you can keep them warm in the oven set to 200°F after they’re done baking. Cover the sheet pan loosely with foil to retain moisture while keeping everything warm.

Can I make the marinade in advance?

Absolutely! You can whisk together the olive oil, lime juice, and chili powder up to 3 days ahead of time. Store it in an airtight container in the fridge, and it’ll be ready to use when you are.

How do I prevent the vegetables from getting too soft?

To keep the veggies crisp-tender, make sure to spread everything out on the baking sheet without overcrowding. Broiling for the last 5 minutes also helps achieve a nice char without making the veggies mushy.

Is it possible to make this recipe dairy-free and gluten-free?

Yes, this recipe is naturally gluten-free, and there’s no dairy involved! If you serve the fajitas with tortillas, simply choose gluten-free tortillas or serve over rice or salad for a gluten-free meal.
