These smoky chicken fajita nachos are loaded with tender chicken, sautéed peppers, onion and gooey cheese. Perfect for sharing - a fun twist on classic nachos! 

They're loaded Tex-Mex style nachos that are perfect for parties, when watching sports, movie nights, or casual dinners, combining the best flavours of fajitas in crispy nacho form.  

The recipe is great for customising by using up leftovers or serving buffet-style.  

Tips

  • Fajita seasoning/chilli chipotle powder – some supermarkets sell chipotle fajita seasoning, so if using this, omit the chilli chipotle powder and use 4 tsp of the chipotle fajita seasoning. 
  • Flavour variations: 
    • BBQ nachos – use barbecue sauce on the chicken and top with crispy onions. 
    • Buffalo nachos – toss the chicken in buffalo sauce and drizzle with ranch or blue cheese dressing. 
    • Breakfast nachos – top the tortilla chips with scrambled eggs, bacon and jalapeños. 
  • This smoky chicken fajita nachos recipe is easily adapted if you’re cooking for less or more people.   You’ll just need a bigger dish if you’re doubling the recipe! 

Frequently Asked Questions

Can I make this in advance?  

It’s best cooked and served fresh, but you can prep all components ahead (chicken, veg, grated cheese) and assemble just before baking.  

How can I make it spicier?  

Add fresh jalapeños, chipotle powder, or hot sauce before baking, or drizzle with sriracha after. 

Can I make it vegetarian?  

Yes - swap the chicken for spiced black beans, mushrooms, or jackfruit.

Can I use shop-bought fajita seasoning?  

Yes, however, homemade spice mixes are easy and customisable.  

How do I avoid soggy nachos?  

Bake uncovered, don’t overload with wet toppings, and add salsa or sour cream after grilling.
