Fajita nachos ingredients

Jump to the recipe for full ingredients and instructions.
- Chicken thighs: I like to use skinless boneless chicken thighs for this recipe, as they have a great flavour and stay nice and juicy. You can use skinless chicken breasts however be careful not to overcook them or they’ll become dry. I’ve also made this using leftover rotisserie chicken in the past which is great to make them even quicker.
- Fajita Seasoning: I make my homemade fajita seasoning using garlic powder, cumin, paprika, chili powder, onion powder and salt. Trust me; make a big batch and keep it on hand. It’s a lovely way to season any meat even if you’re just serving up steaks.
- Capsicum / bell peppers: red, yellow and green peppers give a variety of flavour and colour. You can also swap out one of the 3 peppers for ½ cup of tinned black beans.
- Pickled jalapenos: Optional but great. After realising, I top my nachos with these every single time, I decided to just add them straight in to the veggies when they cook.
- Vegetable oil: I use a neutral flavoured vegetable oil in cooking especially as high heat can destroy the flavour of extra virgin olive oil that you pay such a high price for in the first place. Rice bran oil, canola, avocado oil or even a light flavoured olive oil work great.
- Onion: I like red onion for this but you can certainly use white or brown onion too.
- Cheese: Lots of it. I use a creamy cheddar cheese like colby, but you could also add in some mozzarella for extra stringiness. You can use a classic cheddar cheese too but the flavour can overpower everything else.
- Corn chips: This is the most important choice you’ll make. The best corn chips for nachos are thick and sturdy – they’ll hold their crunch much better and stave off the sog. Don’t go for a regular bag of plain Doritos, they may be great for snacking on but your nachos will be a soggy mess sooner rather than later. Have a good look at the types of corn chips you can get and pick the thicker ones.

What’s the best cheese for nachos?
I touched on it above, but I like a creamy or semi-hard cheddar for these fajita chicken nachos. You want a cheese that has a good strong flavour but also a nice melting texture, so I find a creamier cheddar best. Monterey Jack cheese is a firm favourite if you can get it and Pepper jack is great if you want some extra spice.
You can add a little mozzarella if you want extra melty, stringy cheese but remember it has a very mild flavour so won’t add any flavour to the nachos here.
How to make chicken fajita nachos
You’ll love how simple these fajita chicken nachos are to make and just how quickly they come together. These are truly the ultimate nachos. They have loads of real fajita flavour, juicy chicken, loads of veg so they’re healthier and real cheese. Yum! Lets go!
Jump to the recipe for full ingredients and instructions.
1. Cook the chicken thighs
In a cold pan, combine the chicken, oil and spices then cook them over medium-high heat, turning them a few times so the spices don’t burn, for around 10 minutes. Set that aside on a plate.


2. Cook the vegetables
Now, with the chicken set aside, to the same pan, add the onion, capsicum (bell peppers) and pickled jalapenos.

3. Chop and add the chicken
Turn the heat off the veggies, then roughly chop the chicken and mix them through the veggies making sure to add all the juices from the resting plate.


4. Assembly
Now onto assembling your chicken fajita nachos. Line a large sheet pan with baking paper. Lay your corn chips out onto the tray and scatter some cheese over the top. Spoon your chicken fajita topping over that, then finish off with the rest of the cheese. Now just bake them for 10 minutes.



How to avoid soggy nachos
No one likes soggy nachos, so here are my top tips for crunchy nachos
- Thick corn chips – the thicker the better.
- Cheese between every layer – this creates a bit of a barrier between the filling and the chips.
- Eat it quickly – be ready to dig in as soon as those nachos come out of the oven. There is no avoiding them softening over time.
Toppings for nachos
These chicken fajita nachos have so much flavour and a nice kick of spice so we always serve them with sour cream, avocado (or a guacamole) and lots of coriander / cilantro. Wedges of lime are great served at the table for your guests to squeeze over themselves – a little tang from lime juice is lovely. If you want some extra spice, add some sliced fresh jalapeno too. This fresh jalapeno relish is gorgeous too.
Can I use other meats?
Chicken breast will work as will ground beef or a nice steak. You could also use rotisserie chicken – add shredded rotisserie chicken once the veggies are cooked and along with all the spices making sure to mix it together well.
You can also use this classic homemade taco seasoning, in place of the fajita seasoning.

For best results, always weigh ingredients where a weight is provided
Equipment
- non stick frying pan (best) or large skillet
Instructions
- Preheat the oven to 200C (180C fan forced) / 395F.
- In a cold non stick frying pan, combine the chicken thighs, spice mix and half of the oil. Mix well until the thighs are evenly coated.
- Place pan over medium-high heat and cook for 8-10 minutes, flipping a couple of times so the spices don’t burn and try to splay out the thick parts as it cooks too. Set the chicken aside on a plate.
- Turn the heat down to medium and add the remaining oil to any leftover chickeny flavour in the pan. Add the capsicum, onion and pickled jalapenos, if using. Cook for 3-4 minutes until softened, stirring often.
- Meanwhile, slice the chicken into small pieces.
- Turn the heat off and add the chicken along with any juices from it to the pan. Make sure to scrape in any spices left behind on the chopping board too. Give it a stir to combine everything well.
- Spread the corn chips out on a large pan, overlapping where needed so there are no gaps.
- Scatter over ⅓ of the cheese (this provides a moisture barrier so the chips stay crispier). Now, add the chicken mixture and the remaining cheese.
- Bake for 10-12 minutes or until cheese is melted and bubbly
- Serve immediately, topped with your favourite toppings.

Notes
- Tablespoons: I use a standard Australian 20ml tablespoon (equal to 4 teaspoons). Check yours before measuring.
- Fajita seasoning: Use the recipe below to make your own or see my fajita seasoning recipe to make a larger batch so you have it ready to go any time.
- 2 teaspoons paprika (hot, sweet, mild or smoked)
- 2 teaspoons ground cumin
- 1 teaspoon garlic powder
- 1 ½ teaspoons onion powder
- ½ teaspoon Mexican chilli powder or other (not cayenne)
- 1 teaspoon sea salt or kosher salt
- Cheese: Use a good cheddar cheese grated from the block yourself (so important for texture). I use a creamy cheddar like Edam or Colby which have a slightly milder flavour than classic cheddar cheese and get a good melty texture. Monterey Jack is a popular choice. Use Pepper jack if you want some extra spice. You can also add some mozzarella for even more gooeyness but it is much milder in flavour so keep that in mind.
- Internal temperature of cooked chicken is 75C / 165F.

Point 8 says: Scatter over ⅓ of the cheese (this provides a moisture barrier so the chips stay crispier). Add half the chicken mixture and the remaining cheese.
What happens to the other half of the chicken mix?
My apologies, Philippa. I changed the recipe from 2 layers to one layer and didn’t catch that. Thank you for letting me know. It’s roughly 1/3 of cheese, all the chicken, then the rest of the cheese. I’ve amended the recipe card.
Was such a yummy easy meal enjoyed by all, will definitely be making again
So happy you all love them, Brooke. Thank you so much for dropping back to leave a review 🙂
Made these to watch the grand final on the weekend. Delicious and easy. Thanks for the recipe I will be making these again
So happy you loved them Kim and thanks so much for trying my recipe.
This was such a delicious mid week meal I was able to whip up for the kids. I substituted chicken for mince and it packed a punch with flavour! I have a house full of little fussy eaters so was able to modify so easily for the kids without the capsicum and it was awesome. I am not buying the packet taco seasoning ever again your recipe is a household weekly winner 🏆😋
Thank you so much Deanna. So happy you loved it 🙂
We haven’t been out to have Mexican food in a really long time, this hits the spot!
Thanks Trang, so happy you love it
Our family comforting dish will certainly be a pasta. Next would be a pizza (flatbread) followed by a hearty soup served with toasted bread / cheesy bread. Nachos and other similar thing won’t be our first choice (Indeed, we rarely make this stuff), but looking at your photos, I am 100% ready to change my mind 🙂 This filing looks and sounds scrumptious on its own – no corn chips needed!
So glad I could change your mind Ben 🙂
