Ingredients
Here’s what you’ll need to create this easy, vibrant tray bake:
- 2 medium zucchini, sliced into rounds
- 1 cup cherry tomatoes
- 1 red bell pepper, sliced into strips
- 1 medium red onion, sliced into thin wedges
- 3 tbsp olive oil, divided
- 1 tsp dried oregano
- Salt and pepper, to taste
- 8 oz (225g) halloumi, sliced into thick pieces
- Fresh basil leaves, for garnish
Instructions
This is not too complicated. Throw it all in the tray and bake:
- Preheat the oven:
Preheat your oven to 400°F (200°C) and lightly grease a large baking dish or tray with olive oil. - Prepare the vegetables:
In a large bowl, toss the zucchini, cherry tomatoes, red bell pepper, and red onion with 2 tablespoons of olive oil, dried oregano, and a pinch of salt and pepper. Spread the vegetables evenly across the baking dish. - Roast the vegetables:
Place the baking dish in the oven and roast the vegetables for 20–25 minutes, or until they are tender and slightly caramelized. - Pan-sear the halloumi:
While the vegetables are roasting, heat the remaining 1 tablespoon of olive oil in a non-stick skillet over medium heat. Add the halloumi slices and cook for 2–3 minutes on each side, or until they are golden and crispy. Set aside. - Combine and finish baking:
Once the vegetables are roasted, remove the tray from the oven and arrange the seared halloumi slices on top of the vegetables. Return the tray to the oven for an additional 5 minutes to warm the halloumi. - Garnish and serve:
Remove the tray bake from the oven and garnish with fresh basil leaves. Serve warm as a main dish with crusty bread or as a side to complement your favorite Mediterranean-inspired meal.

Make this tray bake even more versatile and personalized with these ideas:
- Add more veggies:
