How to Make Sheet Pan Chicken Fajita Nachos Recipe
Step 1: Sauté the Bell Peppers and Onions
Start by heating 1 ½ tablespoons of olive oil in a large skillet over medium-high heat. Toss in the sliced red and green bell peppers along with the white onion. Cook for about five minutes, stirring frequently, until they soften and develop those irresistible brown spots that hint at charred, smoky flavor. Once done, transfer the veggies to a large bowl to set aside while you focus on the chicken.
Step 2: Cook the Chicken
Next, add the remaining olive oil to the same skillet and place the bite-sized chicken pieces in it. Cook for 5 to 7 minutes, stirring occasionally, until the chicken is cooked through and has that lightly golden crust. This will form the savory heart of your nachos.
Step 3: Add Seasoning and Lime
In a small bowl, whisk together the fajita seasoning mix and water until well combined. Pour this mixture over the chicken in the skillet, stirring to coat every piece thoroughly. Then add the lime juice and continue cooking for about 3 to 5 minutes. The sauce should thicken slightly, clinging to the chicken and intensifying the flavors beautifully.
Step 4: Assemble and Broil
Arrange your tortilla chips evenly on a medium rimmed baking sheet. Pile on the colorful sautéed vegetables and the seasoned chicken. Generously sprinkle the Mexican cheese blend over the top. Place the sheet pan under the broiler for 2 to 4 minutes until the cheese is bubbling and golden — keep a close eye so nothing burns. The broiling step is what elevates this dish to a whole new level.
Step 5: Add Finishing Touches
Once out of the oven, it’s time to get creative with toppings! Add fresh jalapenos, dollops of salsa, creamy guacamole, and a swirl of sour cream either directly on the nachos or served on the side. These extras bring a wonderful freshness and balance to the hearty, cheesy base.
How to Serve Sheet Pan Chicken Fajita Nachos Recipe

Garnishes
Presentation is half the fun with this dish. Fresh cilantro leaves, sliced green onions, and a sprinkle of chopped tomatoes add vibrant color and fresh flavor that everyone will love. Don’t forget a squeeze of extra lime for that zing that brightens every bite.
Side Dishes
While the Sheet Pan Chicken Fajita Nachos Recipe can stand proudly on its own, pairing it with a simple side salad or some black beans can round out the meal and keep things balanced. A refreshing cabbage slaw or even a bowl of Mexican street corn makes for fantastic accompaniments.
Creative Ways to Present
For a party, serve the nachos family-style on a large platter so everyone can dig in. Alternatively, try layering individual bowls with chips and toppings to create easy-to-eat portions. You can also offer a toppings bar where guests customize their own nachos with different salsas, hot sauces, and fresh veggies.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers, store them in an airtight container in the refrigerator for up to 3 days. Keep any cold toppings like guacamole and sour cream separate to maintain their freshness.
Freezing
Freezing is not ideal for this dish, as the chips tend to get soggy when thawed. However, you can freeze the cooked chicken and sautéed veggies separately in freezer-safe containers for up to 2 months and then reheat before assembling fresh nachos.
Reheating
To reheat leftover assembled nachos, spread them on a baking sheet and warm in a preheated oven at 350°F (175°C) for about 10 minutes or until heated through and the cheese is melty again. Avoid the microwave if possible to keep the chips from becoming too soft.
FAQs
Can I use a different type of cheese for this recipe?
Absolutely! While Mexican cheese blends melt beautifully, you can also use cheddar, Monterey Jack, or even a little queso fresco for a milder flavor. The key is choosing cheese that melts well and complements the spices.
Is there a vegetarian version of the Sheet Pan Chicken Fajita Nachos Recipe?
Yes! Simply swap the chicken with seasoned and sautéed mushrooms, black beans, or plant-based meat alternatives. The colorful peppers and onions still provide that classic fajita flavor.
What can I substitute if I don’t have fajita seasoning mix?
You can make your own blend using chili powder, paprika, cumin, garlic powder, onion powder, oregano, salt, and pepper. Mixing these together will give you a similar, delicious flavor profile.
How spicy is this dish?
The spice level is moderate from the fajita seasoning and optional jalapenos. You can adjust the heat by choosing milder or hotter peppers and seasoning mixes, making it perfect for any preference.
Can I prepare this recipe for a crowd?
Definitely! This recipe scales up well. Use larger sheet pans or multiple pans to make more servings, perfect for parties or big family gatherings. Just maintain the proportions to keep the flavors balanced.
