Instructions

1. 1

   Mix the marinade

   Whisk together all the marinade ingredients. Put the sliced chicken in a bag, pour in the marinade, seal and shake to coat. Marinate for at least 6 hours or overnight, or freeze it.

2. 2

   Drain the chicken

   After marinating, tip the chicken into a strainer and let it drain thoroughly.

3. 3

   Char the vegetables

   While the chicken drains, heat 7.5 ml (½ tablespoon) oil in a cast-iron skillet over high heat until very hot. Add the onion, peppers, salt and pepper, and cook for 5–7 minutes, until tender and charred. Remove the vegetables from the skillet.

4. 4

   Sear the chicken

   Add 15 ml (1 tablespoon) oil to the hot skillet and let it heat. Keeping the heat high, sear half the drained chicken, stirring occasionally, until cooked through, about 5 minutes. Remove it from the skillet and repeat with the remaining chicken.

5. 5

   Toss and serve

   Return the vegetables to the skillet with the chicken and toss them together with tongs. Serve with warm tortillas and the toppings.

What are chicken fajitas?

Fajitas are a Tex-Mex dish inspired by Mexican flavours, traditionally served as sizzling strips of meat with vegetables and tortillas. This skillet version centres on chicken, peppers and onion, with toppings added at the table.

The marinade brings together citrus, soy, spices and a little sweetness, while high-heat cooking gives the chicken and vegetables their browned edges.

Nutrition and macros by portion

The nutrition label shows one serving as written: 249 calories, 18g protein, 15g carbs, 13g fat.

The chicken supplies most of the protein, while the brown sugar, vegetables and tortillas contribute carbohydrates. The oils, chicken and optional toppings such as cheese, avocado and sour cream contribute fat. Serve with plenty of peppers and lettuce, and choose toppings to suit the meal.

Why the marinade works

Citrus juice, mustard and soy sauce make a savoury, tangy base, while brown sugar rounds it out. Cumin, chilli, oregano and chipotle provide warmth and a smoky edge.

Long marinating is part of the method: allow at least 6 hours, or leave the chicken overnight. Drain it well before cooking so excess marinade does not collect in the skillet.

Get the skillet hot

A very hot cast-iron skillet helps the peppers and onion char rather than simply soften. Cook them for 5–7 minutes, then take them out before searing the chicken.

Chicken in batches: sear half at a time and repeat with the rest. This keeps the pan from being crowded and gives the strips room to brown.

Look for these doneness cues

The peppers and onion are ready when they are tender with visible charred spots. Take them out of the pan at that point so they keep some texture.

The chicken should be cooked through after about 5 minutes per batch, with no raw-looking centre. Its final time can vary with the thickness of the strips, so check the thickest pieces.

Build the fajitas

Toss the chicken and vegetables together in the skillet, then serve them with warm corn or flour tortillas. Set out the toppings separately so everyone can assemble their own.

Avocado, salsa, cheese, coriander, lime, sour cream and shredded lettuce are all listed as options. A squeeze of lime just before eating adds a bright finish.

Plan the timing

The stated total time is 35 minutes, but the chicken needs at least 6 hours to marinate, so plan that ahead. The active skillet cooking happens after the draining step.

Slice the chicken and vegetables before heating the skillet so they are ready to cook in sequence. Once the pan is hot, work promptly through the vegetables and chicken batches.

Recipe notes & tips

• Slice the chicken into even strips so it cooks at a similar rate.
• Marinate the chicken for at least 6 hours or overnight, as directed.
• Drain the chicken thoroughly before it reaches the skillet.
• Let the skillet become very hot before adding the vegetables.
• Cook the chicken in two batches rather than crowding the pan.
• Warm the tortillas before serving for a softer wrap.

Variations

• Use flour tortillas: choose them instead of corn tortillas for a softer, pliable wrap.
• Change the peppers: use any mix of bell pepper colours for a varied-looking filling.
• Adjust the smoke: choose regular paprika instead of smoked paprika for a less smoky note.
• Add fresh toppings: finish with avocado, salsa, coriander and lime at the table.
• Make it creamy: offer sour cream and shredded cheese alongside the fajitas.

Common mistakes to avoid

• Skipping the marinade time: allow at least 6 hours or overnight for the chicken to take on the flavour.
• Leaving excess marinade on: drain the chicken thoroughly before searing.
• Starting with a cool skillet: heat the cast-iron pan until very hot before adding the vegetables.
• Crowding the chicken: sear it in two batches so the strips have room in the pan.
• Overcooking the vegetables: remove them once tender and charred, then return them at the end.

How to store

Refrigerate leftover chicken and vegetables in a covered container and use within 3–4 days. Reheat in a skillet until hot throughout; store tortillas and fresh toppings separately where possible.
