Can I use chicken thighs instead of chicken breasts?

Absolutely! Boneless, skinless chicken thighs work beautifully in this recipe and often stay juicier than breasts. The cooking time remains about the same, but check for doneness using a meat thermometer (165°F).

How can I make this recipe spicier?

Easy! Add a diced jalapeño or serrano pepper to your vegetable mix before roasting. You can also incorporate cayenne pepper into your fajita seasoning, or serve with hot sauce on the side. For milder heat, just remove the seeds and membranes from your hot peppers.

Can I make this recipe vegetarian?

Definitely! Replace the chicken with firm tofu, portobello mushroom strips, or an extra cup of bell peppers and add a can of rinsed, drained black beans to the sheet pan during the last 10 minutes of cooking. The beans add protein and hearty texture to your vegetarian fajitas.

Is there a way to make this recipe ahead for meal prep?

Yes! Cook everything as directed, then store the fajita mixture separately from the tortillas and garnishes. When ready to eat, reheat the fajita mixture in a skillet and warm tortillas just before serving. This works great for up to 3 days of quick meals.

Ingredients You’ll Need

Boneless, skinless chicken breasts: The star protein that soaks up all those fantastic fajita flavors. Cut them into strips for quick, even cooking.
Bell peppers: Any color works great! They add sweetness, crunch, and beautiful color to your fajitas. Red, yellow, and orange are slightly sweeter than green.
Yellow onion: Provides a savory base flavor that caramelizes beautifully in the oven, adding natural sweetness to the dish.
Roma tomatoes: These low-moisture tomatoes intensify in flavor when roasted, adding juicy freshness without making your fajitas soggy.
Greek yogurt: Creates a tangy, protein-rich marinade for the chicken that helps tenderize while adding flavor. It’s a healthier alternative to sour cream!
Fajita seasoning: The flavor powerhouse that brings everything together. Store-bought works perfectly, but homemade gives you control over spice levels.
Fresh cilantro: Brings a bright, citrusy note that cuts through the richness of the other ingredients. A little goes a long way!
Flour tortillas: Medium-sized tortillas are perfect for holding all your fillings without overwhelming them. Warming them makes them pliable and enhances their flavor.
Optional garnishes: Queso fresco adds creaminess, extra cilantro brightens, lime adds tang, and more Greek yogurt cools things down.

How to Make Sheet Pan Chicken Fajitas

Step 1: Prepare Your Sheet Pan

Preheat your oven to 400°F and give your baking sheet a good spray with nonstick spray. This prevents sticking and makes cleanup even easier.

Step 2: Prep the Vegetables

Mix together your diced tomatoes, sliced onion, and colorful bell pepper strips, then spread them evenly on the baking sheet. Try to create a single layer for more even roasting.

Step 3: Season the Chicken

In a small bowl, combine Greek yogurt, fajita seasoning, and freshly chopped cilantro until well mixed. Add your chicken strips and toss until each piece is thoroughly coated with this flavorful marinade.

Step 4: Arrange and Bake

Place the seasoned chicken strips among the vegetables on the sheet pan, distributing them evenly. Pop the pan in your preheated oven and bake for 20-25 minutes, until the chicken is completely cooked (reaching 165°F internally) and the vegetables have softened and begun to caramelize at the edges.

Step 5: Warm the Tortillas

About 8 minutes before everything is finished, wrap your tortillas in aluminum foil and place them in the oven alongside your fajita mixture. This gentle warming makes them soft, pliable, and enhances their flavor.

Step 6: Serve and Enjoy

Bring the sheet pan to the table or transfer to a serving platter. Let everyone build their own fajitas with the warm tortillas and optional garnishes like queso fresco, extra cilantro, lime wedges, and more Greek yogurt.

Pro Tips for Making the Recipe

Even Cutting: Try to cut chicken strips and vegetables to similar sizes for even cooking.
Don’t Overcrowd: Give ingredients some breathing room on the sheet pan—overcrowding leads to steaming instead of roasting.
Check Doneness: Chicken should reach 165°F internally. If it’s done before your vegetables are as caramelized as you’d like, remove the chicken and continue roasting the veggies.
Flavor Boost: For even more flavor, marinate the chicken in the yogurt mixture for up to 4 hours in the refrigerator before cooking.

Make Ahead and Storage

Prepping Ahead

Slice all vegetables and chicken up to 24 hours in advance. Store separately in airtight containers in the refrigerator. You can even mix the yogurt marinade ahead of time, but don’t add it to the chicken until you’re ready to cook.

Storing Leftovers

Store any leftover fajita mixture in an airtight container in the refrigerator for up to 3 days. Keep leftover tortillas in their original packaging or wrapped tightly in foil.

Reheating

For best results, reheat the fajita mixture in a skillet over medium heat until warmed through, about 3-5 minutes. This maintains texture better than microwave reheating. Warm tortillas in a dry skillet or wrapped in damp paper towels in the microwave for 15-20 seconds.

Freezing

The fajita mixture (without garnishes) can be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating. The texture of the vegetables will soften somewhat upon thawing.
