Chicken Fajita Nachos

If you’re anything like me, when you’re feeding a crowd, unless your guests are waddling out on all fours, you’ve completely failed as a host. I mean heaven forbid anybody walks out even the slightest bit hungry. Genuinely sends shivers down my spine 😂 These nachos are PERFECT for sending a room of people into a food coma, but here’s why else I think you’ll love them:

  • Easy – Even the most beginner of cook can master these nachos!
  • Flavoursome – Not just regular cheese and tortilla chips, these chicken nachos really pack a punch in the flavour department.
  • Adjustable – Easy to adjust for smaller or bigger crowds.

Ok, gimme a nacho, I’m getting hungry all over again…

Homemade Fajita Chicken

For this recipe, I go with chicken breast and dice it up nice and small. I find larger chunks of chicken tend to overpower the nachos a little. In terms of seasoning, you can just grab store bought fajita seasoning, or make my Homemade Fajita Seasoning. Of course, I recommend the latter 😏

Apart from that, it’s just a case of using mixed peppers, onion, jalapeños (optional) and a nice squeeze of lime juice. Simples!

How to make Fajita Chicken for Nachos (quick summary)

  1. Dice chicken.
  2. Add seasoning.
  3. Stir to combine.
  4. Add to medium-high heat with oil.
  5. Fry until cooked through/lightly charred.
  6. Remove & add peppers/onion/jalapeño.
  7. Fry until soft, add seasoning.
  8. Mix in chicken and lime juice.

What oil to use? – I recommend using Avocado Oil as it adds flavour and has a high smoking point. Fajitas have a classic char to them and an oil like avocado oil helps when cooking at high heat. Having said that, any oil you have on hand will be a fine sub.

Double Decker Nachos

Because seriously, are nachos even nachos if they aren’t double decker?! I mean yes. All nachos are great. But double decker is better.

How do I prevent my nachos from going soggy?

  1. Chip – ensure you choose a sturdy chip. Nothing thin a flimsy. A nice strong tortilla chip to hold the weight.
  2. Moisture – when you fry the veg make sure you properly sweat it all down to remove as much moisture as possible.
  3. Speed – make sure you eat ’em fast! No messing around, straight out of the oven, straight into the face. The longer they sit the more chance they steam themselves into a soggy infinity.

How to make Chicken Fajita Nachos (quick summary)

  1. Spread tortilla chips.
  2. Top with fajita chicken.
  3. Top with cheese.
  4. More tortilla chips.
  5. More chicken.
  6. Finish with cheese and bake!

Chicken Fajita Nachos FAQ

What cheese to use for chicken fajita nachos? – I recommend cheddar and/or Monterey Jack. You can add a bit of mozzarella for a cheese pull, but not too much as it’ll dilute the cheesy flavour.

Can I use beef?

You could sub the chicken and use ground beef with the exact same spice mix. It would just be less ‘fajita nachos’ and more ‘Mexican ground beef nachos’. I recommend 500g/1lb.

Can I use leftover rotisserie chicken?

Sure! Just shred the chicken with the spices and fry for a few mins in some oil, just to lock in the flavours.

How spicy are these nachos?

They do have a good kick of spice, but nothing overly dramatic. If you’re at all wary of spice, you can reduce the cayenne pepper in the spice mix and/or reduce/omit the jalapeños. You can then serve with more jalapeños on top if you want more spice!

Serving Chicken Fajita Nachos

When it comes to serving the nachos, I love to finish with some coriander/cilantro for a pop of flavour and colour. I also like to serve with some Guac, Salsa and Sour Cream. I recommend serving these in pots to one side, not on top of the nachos. Mainly because not everyone might like them, but mostly because you’re adding unwanted moisture to the nachos.

If you like the sound of these nachos, I’m confident you’ll love my BBQ Chicken Nachos, No Bake Nachos, Irish Nachos and Gnocchi Nachos. Also give these similar recipes a ganders:

Quick 1 min demo!


a) Half portion - The whole recipe will comfortably feed 8. It's easily divided in half, just use the serving slider at the top of the recipe card.
b) Cheese - I usually go for 3/4 cheddar and 1/4 mozzarella. Pepper Jack/Monterey Jack also works great.
c) Lime Juice - This is optional, but does add a nice kick of flavour and brings out the spices in the chicken. Just don't go overboard or you'll add too much moisture and risk the nachos ending up soggy!
d) Tortilla Chips - Opt for a nice thick, sturdy chip. This will keep things keep them from going mushy too quickly, especially if you're doing double-decker.
e) Eat 'em up quick - The longer you leave them, the less melty the cheese will be and the more chance of the tortilla chips going soggy. Also, 15mins is just a guidance. You really only need them in the oven long enough the melt the cheese (as the chicken is already cooked).
f) Calories - shared between 8 people, using 3 cups Monterey jack cheese and 1 tbsp + 1 tsp avocado oil to fry. No side dips.
