Sheet Pan Chicken Nachos
This chicken fajita nachos recipe is so delicious! You have tender and juicy seasoned chicken with perfectly cooked vegetables. Added on top is sour cream, Mexican cheese, salsa, and guacamole. You can add freshly squeezed lime or pico de gallo on top to add even more flavor.
This is my favorite appetizer to make for any gathering and easily baked on a sheet pan! If you’re not a fan of fajitas with the addition of peppers, try our chicken nachos with queso – it’s so delicious as well!

Different Meats for Sheet Pan Nachos
This sheet pan nachos recipe is made with chicken which is one of our favorite meats for Nachos. However, if you want to add different types of meat, you can definitely change it! Simply replace the chicken with ground beef, ground turkey, strips of skirt steak, pork, or any other meats you prefer.
Best Toppings For Chicken Fajita Nachos
The best part of Nachos (other than the melted cheese) are the additional toppings. Here are some other topping suggestions: black olives, shredded lettuce, beans (such as pinto beans, black beans, or refried beans), avocado crema, diced red onion, white queso, tomatoes, corn, candied jalapenos, salsa verde, sliced avocado and any other veggies of your choice.
Tips and Variations
Air Fry – if you’d rather not heat the oven, follow our directions for Air Fryer Nachos for heating.
Sheet pan nachos work great with leftover chicken. If you have leftover chicken from Slow Cooker Queso Chicken Tacos or Slow Cooker Ranch Chicken Tacos, you can use it in this recipe. Leftover rotisserie chicken is also great to use.
Cheese – any Mexican cheeses will work like Monterey Jack cheese, or sharp cheddar cheese.
Chips – any kind of tortilla chips will work or you can even use corn chips like Fritos!
Leftovers – Unfortunately, nachos really do not keep well and chips get soggy when refrigerated. Consider cutting the recipe in half if you don’t think you can finish it. Just bake it on a smaller pan!
