Halloumi and Roasted Vegetable Traybake

A halloumi and roasted vegetable traybake is the kind of vegetarian dinner that relies on high heat, generous spacing and bold, simple seasoning. Courgette, red pepper, red onion, garlic and cherry tomatoes soften and catch at the edges, while the halloumi turns golden, salty and crisp on the outside without losing its chewy centre. Dried oregano gives the tray a herby Mediterranean feel, and lemon zest and juice added at the end keep the richness in check. Served straight from the baking tray, it works well as a low-effort main with bread, grains or a green salad alongside.

Why this recipe works

  • Simple traybake method: The vegetables and halloumi roast on one tray, keeping the workflow straightforward and the washing up low.
  • Crisp-edged halloumi: Adding the halloumi partway through cooking lets it turn golden without overcooking before the vegetables are tender.
  • Bright finish: Lemon zest and juice lift the salty cheese and roasted vegetables, keeping the dish fresh rather than heavy.

Texture tips

  • Give the vegetables space: Keep everything in a single layer so the vegetables roast and caramelise rather than steam.
  • Add halloumi later: Nestling the halloumi into the tray after the first roast helps it brown at the edges while staying soft inside.

Ingredient notes

  • Check the halloumi: Halloumi varies in saltiness; if yours tastes very salty, soak it briefly in cold water and pat it dry before roasting.
  • Oregano choice: Dried oregano gives a deeper, more concentrated flavour, while fresh oregano brings a softer, greener note.

Timing notes

  • Serve while hot: Halloumi is at its best straight from the oven, when the edges are crisp and the centre is still tender.
  • Best freshly roasted: Leftovers keep well, but the cheese will soften as it chills and only partially re-crisp when reheated.

Serving ideas

  • Add a simple base: Serve with warm flatbreads, couscous, rice or a leafy salad to turn the traybake into a fuller meal.
  • Pair with something cool: A spoonful of yoghurt, tzatziki or a tahini-lemon sauce works well against the salty, roasted flavours.

  1. Heat the oven to 220°C (430°F). Cut the courgettes into thick half-moons, the peppers into chunky pieces, and the onion into wedges; lightly crush the garlic cloves.
  2. Tip the courgette, red pepper, red onion, garlic and cherry tomatoes onto a large baking tray. Drizzle over the extra virgin olive oil, sprinkle with the dried oregano, then toss well and spread out into a single layer.
  3. Roast for 15 minutes, then give everything a quick turn so it colours evenly. Keep the vegetables spread out so they roast rather than steam.
  4. Slice the halloumi into pieces about 1 cm thick. Nestle the halloumi among the vegetables and return the tray to the oven for 12 to 15 minutes, until the halloumi is golden and the vegetables are tender with charred edges.
  5. Finely grate a little lemon zest over the tray, then cut the lemon in half and squeeze over the juice to taste. Serve straight from the tray while the halloumi is hot and crisp at the edges.

Recipe notes

Tips

  • For the best colour, avoid overcrowding the tray; if your tray is small, use two trays and swap shelves halfway through roasting.
  • If your halloumi is very salty, soak it in cold water for 10 minutes, then pat dry before roasting.
  • If serving to pregnant people, older adults, or anyone immunocompromised, make sure the halloumi is cooked until piping hot throughout.

Substitutions

  • Replace Dried oregano with fresh oregano for a softer, greener flavour.
  • Replace Lemon with lime for a sharper, more aromatic finish.

Storage

  • Refrigerate up to 3 days
  • Cool, then refrigerate in an airtight container. Reheat on a baking tray at 200°C (390°F) for 10 to 12 minutes until piping hot; the halloumi will soften on chilling but will re-crisp slightly in the oven.
