Mexican Chicken Traybake with Sweet Potato and Chipotle Lime

A Mexican-style chicken traybake brings the ease of sheet-pan cooking to the flavours of chipotle, lime, cumin and sweet paprika. Bone-in, skin-on chicken thighs roast among sweet potato, red pepper and red onion, so the vegetables soften and caramelise while the chicken turns golden and savoury. The chipotle lime marinade gives gentle smoky heat and brightness without needing a separate sauce, and warm corn tortillas make it easy to serve everything straight from the tray. A scattering of fresh coriander lifts the rich roasted flavours at the end.

Why this recipe works

  • Efficient one-tray cooking: The chicken and vegetables roast together, so the marinade seasons everything while the oven does most of the work.
  • Smoky, tangy depth: Chipotle sauce brings smoke and heat, while lime juice, cumin and paprika add brightness and savoury warmth.
  • Caramelised vegetables, crisp chicken: A hot oven helps the sweet potato and peppers brown at the edges while the chicken skin turns golden.

Get the most out of this recipe

Adjust the heat

  • For less heat: Use a little less chipotle sauce and add extra lime at the end to keep the marinade bright.
  • For more heat: Add more chipotle sauce to the marinade, or finish with sliced fresh chilli before serving.
  • Keep the flavour balanced: If increasing the heat, taste before serving and adjust with lime or a pinch of salt so the smoky chilli does not dominate.

Texture tips

  • Use a large tray: Spread the vegetables in a single layer so they roast and caramelise rather than steam.
  • Crisper chicken skin: Keep the chicken skin-side up and move the tray higher in the oven for the final few minutes if it needs more colour.

Make-ahead tips

  • Prep ahead: The vegetables can be cut and the marinade mixed earlier in the day, then tossed together just before roasting.
  • Reheat properly: Reheat the chicken and vegetables on a baking tray at 200°C (390°F) until piping hot, warming the tortillas separately.
  • Freezer-friendly filling: Freeze the cooked chicken and vegetables without the tortillas, then defrost in the fridge before reheating.

Serving ideas

  • Add freshness: Serve with shredded lettuce, avocado or a simple tomato salsa for a fresher plate.
  • Good sauce options: A spoonful of soured cream, yoghurt or a limey crema works well against the smoky chipotle.
  • Finish with herbs and lime: Fresh coriander and extra lime wedges sharpen the roasted flavours just before serving.

  1. Heat the oven to 220°C (430°F). In a large bowl, whisk together the olive oil, chipotle sauce, juice of 2 limes, ground cumin and sweet paprika. Finely grate or crush the garlic into the bowl and mix well.
  2. Peel the sweet potato and cut into 2 cm chunks. Cut the red onions into wedges and the red peppers into thick strips, discarding the seeds. Add the vegetables to the bowl and toss until well coated.
  3. Tip the vegetables onto a large baking tray and spread into an even layer. Add the chicken thighs to the bowl, turn to coat in the remaining marinade, then nestle them among the vegetables skin-side up. Roast for 35 to 40 minutes, turning the tray once, until the chicken is deeply golden and cooked through and the vegetables are tender and caramelised.
  4. Warm the corn tortillas in the oven for 2 to 3 minutes, or until pliable. Roughly chop the fresh coriander. Serve the traybake with the warm tortillas and scatter over the coriander.

Tips

  • For the best caramelisation, keep the vegetables in a single layer and use a large tray so they roast rather than steam.
  • If the chicken is cooked but the skin needs more colour, move the tray to a higher shelf for the final 3 to 5 minutes and keep an eye on it.
  • If serving anyone who is pregnant, elderly, or immunocompromised, make sure the chicken is cooked until piping hot throughout with no pink at the bone.

Substitutions

  • Replace Chicken thighs with Chicken drumsticks, keeping the same roasting time and checking they are cooked through.
  • Replace Chipotle sauce with Harissa for a different smoky heat.
  • Replace Fresh coriander with Fresh flat-leaf parsley if you prefer a milder herb finish.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then refrigerate in an airtight container for up to 3 days. Reheat on a baking tray at 200°C (390°F) for 12 to 15 minutes until piping hot; warm the corn tortillas separately. Freeze the chicken and vegetables (not the tortillas) for up to 2 months and defrost overnight in the fridge before reheating.
