Ingredients (makes 4 main servings or 6-8 sides)

  • 6 tbsp extra virgin olive oil, divided (90 ml ml)
  • 1 small red onion (60 g/ 2.1 oz)
  • 1 large zucchini (250 g/ 8.8 oz)
  • 1 small red bel pepper (74 g/ 2.6 oz)
  • 1/2 small head broccoli (200 g/ 7.1 oz)
  • 1/2 cauliflower (225 g/ 8 oz)
  • 1/2 tsp sea salt
  • 1/4 tsp black pepper
  • 1 package halloumi cheese, cubed (250 g/ 8.8 oz)
  • 1/2 cup mixed, pitted olives (50 g/ 1.8 oz)
  • 12 cherry tomatoes (140 g/ 5 oz)
  • 1/3 cup loosely packed basil leaves, torn
  • 2 tbsp fresh lemon juice (30 ml)


  1. Preheat oven to 200 °C/ 400 °F (conventional), or 180 °C/ 355 °F (fan assisted). To prepare the vegetables, cut the zucchini into small (about 2.5 cm/ 1 inch) rounds. Cut the onion into wedges. Chop the pepper into thick strips.

  2. Cut the cauliflower and broccoli into smaller florets. Smaller pieces are better as they will cook faster and more evenly.
  3. Add to a heavy baking tray, and toss with 3 tablespoons of the olive oil, salt and pepper.

  4. Bake for 15 minutes, stir, and then return to the oven for another 10 to 15 minutes.
  5. Cut the halloumi into cubes, and scatter across the vegetables, along with the olives and cherry tomatoes.
  6. Return to the oven for another 10-15 minutes or until the halloumi is starting to brown.

  7. Toss with fresh basil, lemon juice and the remaining 3 tablespoons of olive oil.

  8. Serve immediately, or store in the fridge for up to 5 days. Reheat in the oven or microwave before serving. Cold halloumi is very chewy and always needs to be reheated. Low-Carb Roasted Vegetable & Halloumi Tray Bake

Thanks for sharing, I’ve made this dish several times since discovering it! Might just be my oven but I have to leave the veggies roasting a lot longer or else they are still crunchy. I’m not on a specific diet, just trying to increase the amount of veggies I eat, so I have also tried reducing the halloumi and adding a bit of chorizo at the end, gives it a little extra zing!


Thank you Hannah, I'm glad you enjoyed! Let me double check that with Dearna just to be sure the instructions are right. I'll add a note in any case!
PS: Love the addition of chorizo! 😊


Excellent side dish!  I will do this one a lot!!!


This was amazing!  We used feta instead of halloumi (which is very expensive where I live).  Wonderful mix of flavors and very easy to prepare.


Thank you Krissie, I'm happy you enjoyed!
