What Is the Best Way to Keep Fajitas Juicy?

Nobody likes dry chicken! To keep your fajitas tender and full of flavor: Marinate the chicken for at least 30 minutes before cooking. Don’t overcook! Bake at 400°F and check for doneness at 20 minutes. Slice against the grain to keep the meat soft and easy to chew.

Can I Use Frozen Chicken for This Recipe?

Yes, but thaw it first! Cooking frozen chicken directly on a sheet pan can lead to uneven cooking. For best results: Thaw overnight in the fridge. Pat dry before seasoning to help the spices stick.

How Do I Make Sheet Pan Chicken Fajitas Spicier?

If you love heat, try these add-ins: Cayenne pepper or extra chili powder in your spice mix. Sliced jalapeños or serrano peppers for extra kick. Hot sauce drizzled on top before serving.

What Are the Best Tortillas for Fajitas?

It depends on your preference! Flour tortillas – Soft, stretchy, and great for wrapping. Corn tortillas – More authentic with a slight chew. Low-carb or gluten-free tortillas – Great for dietary needs.

Can I Cook These on a Stovetop Instead?

Absolutely! If you don’t want to turn on the oven, simply: Heat a large skillet over medium-high heat. Sauté the chicken first , then remove once cooked. Cook the peppers and onions until slightly charred. Toss everything together , squeeze in fresh lime juice, and serve!
