They’re all designed to be realistic enough for busy weeknights while still feeling exciting enough that you actually look forward to dinner. And these fajitas tick every single box.

Everything cooks together in the air fryer, meaning minimal washing up, very little hands-on cooking and dinner on the table in just 20 minutes. It honestly doesn’t get much easier than that.

Nutrition

One of the reasons I’ve made this recipe so many times over the years is because it gives you everything I look for in a balanced meal. Each serving provides:

576 calories
57g protein
45g carbohydrates
21g fat
8g fibre

The chicken provides plenty of lean protein to help keep you full and support muscle recovery, while the peppers and onions add fibre, vitamins and natural sweetness as they caramelise in the air fryer. Wrapped inside a tortilla, it becomes a complete meal that feels indulgent but is actually packed with goodness.

It’s proof that healthy eating doesn’t have to mean boring food.

Step-By-Step Instructions

Step 1 – To the air fryer basket add all the chopped vegetables.
Step 2 – Add the sliced chicken.
Step 3 – Add the mix of spices.
Step 4 – Mix well until everything is evenly coated, then bake.
Step 5 – Mix half way through baking.
Step 6 – Fill the wrap with chicken, veggies, yoghurt, coriander, and lime juice.

Tips

Slice the chicken thinly: Thin strips cook faster and absorb the fajita seasoning better.
Use a pre-heated air fryer: This helps the chicken and veggies cook more evenly.
Shake or mix halfway through: Additionally, toss the basket at the halfway mark so everything crisps and browns evenly.
Make it low carb: Swap the wrap for lettuce cups or serve with a side salad.
Add extra veg: Mushrooms, courgette, or cherry tomatoes roast well and bulk out the meal.
Serve with lime wedges: A little squeeze of fresh lime at the end brightens all the flavours.
Meal prep tip: Cook the filling ahead and store it in the fridge—just reheat in the air fryer or pan for 3–4 minutes.

Yoghurt Sauce

For me, the sauce is what brings everything together.

Instead of using sour cream, I make a quick sauce with Greek yoghurt, fresh lime juice and coriander. It’s creamy, fresh and cooling, balancing the smoky fajita seasoning perfectly while adding even more protein to the meal.

Don’t skip it—it takes less than a minute to make and completely transforms the fajitas.

Here’s how:
Mix 100g plain yoghurt, ½ tsp garlic powder, and ¼ tsp salt. That’s it!
Altogether, it’s creamy, full of flavour, and so much better than anything that comes from a bottle at the supermarket!

The Best Toppings

One of the things I love most about fajitas is that everyone can build their own.

I like to load mine with plenty of the yoghurt sauce, fresh coriander and an extra squeeze of lime. If I’m feeling extra hungry, I’ll add sliced avocado for healthy fats and even more creaminess.

Other delicious toppings include:

Sliced avocado
Fresh coriander
Pickled jalapeños
Fresh tomato salsa
Grated cheese
Extra lime wedges
Shredded lettuce
Pickled red onions

Everyone can make theirs exactly how they like it, which makes these perfect for family dinners or feeding friends.

Meal Prep Friendly

These fajitas are brilliant for meal prep too.

Simply cook the chicken and vegetables, store them in the fridge for up to 3 days and reheat before serving. Keep the wraps, yoghurt sauce and toppings separate until you’re ready to eat for the freshest result.

They’re also delicious served over rice, inside a salad bowl or with roasted potatoes if you fancy changing things up.

Serve With

This recipe is incredibly versatile, so you can enjoy it in a variety of ways depending on what you’re craving. Whether you’re in the mood for something light, hearty, or fresh, there’s a delicious option for every appetite.

Classic fajitas: Serve the smoky chicken and peppers in warm tortillas (flour or corn both work well). Add a dollop of Greek yoghurt or sour cream, a squeeze of lime, and some fresh coriander.
Bowl-style: Make a fajita bowl with rice or quinoa as the base. Top with the chicken mix, shredded lettuce, chopped tomatoes, avocado or guacamole, and a spoonful of yoghurt or salsa.
Low-carb option: Serve over a bed of mixed greens or in crunchy lettuce cups for a lighter, low-carb version.
Stuffed sweet potatoes: Roast sweet potatoes, split them open and stuff with the chicken and veg. Finish with yoghurt, cheese or sliced spring onions.
Loaded nachos: Spread tortilla chips on a tray, scatter over the fajita mix, sprinkle with grated cheese, and grill for a few minutes. Top with jalapeños, salsa and yoghurt.
Leftovers idea: Add the mix to an omelette or scrambled eggs for a quick high-protein breakfast the next day.

Flo’s Top Tips

Slice the chicken evenly so everything cooks at the same rate.
Don’t overcrowd your air fryer basket. If needed, cook in two batches so the vegetables roast instead of steaming.
Give everything a shake halfway through cooking to ensure even caramelisation.
Warm your tortillas before serving—they’re softer, easier to fold and taste so much better.
Finish with plenty of fresh lime juice just before serving. It brightens all the flavours and makes the whole dish taste even fresher.

If you’re looking for a quick dinner that’s high in protein, full of flavour and genuinely easy enough for a busy weeknight, these chicken fajitas are hard to beat. They’ve been part of my weekly meal rotation for years, and I don’t think I’ll ever get bored of them.

Swaps

Chicken breast: I used this for a leaner, lower-calorie option. However, if you want extra juiciness, chicken thighs work really well.
Tofu or tempeh: For a plant-based version, simply swap the chicken with tofu or tempeh—just press it well first so it crisps up nicely in the air fryer.
Vegetables: No peppers or onions? You can use mushrooms, courgette, or cherry tomatoes instead. It’s also a great way to use up what you already have in the fridge.
Seasoning: If you don’t have fajita seasoning, make your own using smoked paprika, cumin, oregano, garlic powder, and chilli flakes.
Yoghurt: I like to use Greek yoghurt for extra protein. Alternatively, coconut yoghurt or other dairy-free options work well too.
Wrap: Choose wholemeal, gluten-free, or low-carb wraps depending on your preferences and dietary needs.
Avocado: Swap with guacamole or thinly sliced cucumber for a lighter, crunchy option.

Storage

Fridge: Store the cooked air fryer fajita filling in an airtight container for up to 3 days. Reheat in the air fryer at 180°C for 3–4 minutes or in a pan over medium heat until hot.
Freezer: Freeze the cooked chicken and vegetables in a sealed container for up to 2 months. Defrost overnight in the fridge and reheat in the air fryer or a non-stick pan.
