• Juice of 1/2lime
• 1 tspchilli powder
• 1/4 tspcumin
• 1/2 tsp, plus extra for fryinglight olive oil or vegetable oil
• 1/4 tsp (or a pinch for less heat)cayenne pepper
• 1/4 tspdried oregano
• 1white onion
• 1red pepper
• To tastesalt

Instructions

1. 1

   Marinate the chicken

   Mix the chilli powder, cumin, olive oil, cayenne, oregano, lime juice and a pinch of salt in a small bowl. Cut the chicken into small, bite-sized strips, add them to the bowl and toss to coat. Cover with cling film and refrigerate for at least 1 hour.

2. 2

   Slice the vegetables

   When ready to cook, cut the onion into thin wedges about 1 cm thick. Slice the red pepper into strips.

3. 3

   Cook the vegetables

   Heat a little oil in a large pan over a medium-high heat. Fry the onion and pepper together for a few minutes, until the onion is nearly soft and has picked up some colour. A wok works well, especially if you are making a larger batch.

4. 4

   Cook the chicken

   Add the chicken and any marinade left in the bowl. Cook over a high heat for about 6–10 minutes, until the chicken is cooked through and white all the way through. The timing depends on the thickness of the strips.

5. 5

   Serve the fajitas

   Bring the pan to the table to help keep the chicken and vegetables warm. Serve with warmed tortillas and small bowls for people to help themselves.

What are chicken fajitas?

Fajitas are a Tex-Mex favourite, commonly served as sizzling or freshly cooked strips of meat and vegetables with tortillas for wrapping. This homemade version uses lime and a simple spice mix to flavour the chicken, then cooks it with onion and red pepper.

The approach works well because the chicken marinates ahead while the vegetables are sliced just before cooking. Everything comes together in one pan, making it easy to serve for a casual shared meal.

Nutrition and macros by portion

The nutrition label shows one serving as written: 230 calories, 32g protein, 10g carbs, 7g fat.

The chicken supplies most of the protein, while the onion, pepper and lime contribute carbohydrates. The oil carries most of the fat; tortillas, if served alongside, add more carbohydrates and calories but are not included in this estimate. For a balanced plate, serve with a generous amount of pepper and onion alongside the chicken.

The marinade and its heat

Spice mix: chilli powder, cumin and oregano give the chicken savoury, earthy flavour, while lime juice brings a sharp note. A little oil helps the mixture coat the strips.

Cayenne: this is the main source of heat in the mix. Use the full amount for a spicier result or reduce it to a pinch.

Cut for quick cooking

Chicken strips: keep them bite-sized and reasonably even in thickness so they cook at a similar rate. The recipe’s cooking time is a guide because thicker pieces take longer.

Vegetables: cut the onion into thin wedges and the pepper into strips, as directed. This gives them time to soften and colour while the chicken cooks.

Get the pan ready

Room to cook: a large pan or wok gives the chicken and vegetables space to cook over high heat. For a larger batch, a wok can be especially handy if your usual pan is too small.

Vegetable colour: start the onion and pepper first over medium-high heat. Add the chicken when the onion is nearly soft and has some colour.

Check the chicken is cooked

Timing: cook the chicken for about 6–10 minutes over high heat after adding it to the pan. The time varies with the thickness of the strips.

Doneness: the method calls for chicken that is white all the way through. Avoid judging it by the clock alone if your pieces are thicker or thinner than usual.

Serve straight from the pan

Warm tortillas: serve them alongside the chicken and vegetables so everyone can make their own fajitas. Small bowls make it easy to share the components.

For the table: keeping the food in the pan helps it stay warm as people serve themselves. Lime wedges or a margarita are optional accompaniments mentioned by the original recipe.

Recipe notes & tips

• Marinate the chicken for at least 1 hour, as directed, and do it ahead if that suits your schedule.
• Cut the chicken into strips of similar thickness to help them cook evenly.
• Use a large pan or wok so the ingredients have room to cook.
• Keep the cayenne to a pinch if you prefer milder fajitas.
• Set out the warmed tortillas and small bowls before bringing the pan to the table.

Variations

• Milder heat: Use just a pinch of cayenne instead of the full 1/4 tsp.
• More citrus: Serve with lime wedges for an extra squeeze at the table.
• Alternative oil: Choose light olive oil or vegetable oil, as listed.
• Bigger batch: Multiply the ingredients and use a wok or another suitably large pan.
• Shared spread: Put the chicken and vegetables in the middle of the table with warmed tortillas for everyone to assemble.

Common mistakes to avoid

• Too much cayenne: It brings the main heat, so start with a pinch if you are unsure.
• Uneven chicken strips: Pieces of different thicknesses finish at different times; cut them to a similar size.
• Skipping the marinade: The chicken needs at least 1 hour in the fridge to take on the lime and spice mixture.
• Crowded pan: A small pan can make a larger batch awkward to cook; use a wok or a larger pan.
• Relying only on the timer: Check that the chicken is white all the way through, as thickness affects the 6–10 minute cooking time.

How to store

Refrigerate leftover chicken and vegetables in a covered container and use within 3–4 days. Reheat until piping hot before serving; store tortillas separately.
