Grilled Halloumi with Roasted Zucchini and Lemon Herb Oil
There is something almost magical about the way halloumi behaves in a hot pan. If you’ve never worked with it, prepare for a treat. Unlike most cheeses that melt into a puddle, halloumi holds its shape, developing a deep, golden-brown crust that shatters under your fork before revealing a soft, warm interior. I often tell my clients that this is the "steak" of the vegetarian world—it has that same satisfying density and savory punch.
I first fell in love with this combination on a breezy patio in the Mediterranean, where the simplicity of the ingredients was the real star. When we roast zucchini until it’s lightly caramelized, it loses its raw, watery edge and transforms into something mellow and sweet. Paired with a sharp, garlicky lemon oil, the dish becomes a balance of heavy and light, salty and acidic. It’s the kind of meal that leaves you feeling satisfied, not heavy.
The Essential Ingredients
- 250g Halloumi cheese, sliced into 1/2-inch thick slabs
- 3 medium zucchinis, sliced into rounds
- 2 tbsp extra virgin olive oil (plus extra for drizzling)
- 1 tsp dried oregano (or dried thyme)
- 1/4 cup fresh flat-leaf parsley, finely chopped
- 1 tbsp fresh lemon juice
- 1 clove fresh garlic, finely minced
- Sea salt to taste
- Freshly cracked black pepper
- Optional: 2 tbsp toasted pine nuts for crunch
The Process
- Prep and Roast: Preheat your oven to 200°C (400°F). While the oven works its magic, slice your zucchini into half-inch thick coins. Toss them in a bowl with two tablespoons of olive oil, the dried oregano, a generous pinch of sea salt, and a few cracks of black pepper. Spread them in a single layer on a parchment-lined tray. Roast for 15–20 minutes. You want them to be tender with edges that are just beginning to turn a sun-drenched golden brown.
- The Sear: As the zucchinis hit that perfect color, grab a non-stick or well-seasoned cast-iron skillet. Set it over medium heat. Place your halloumi slices directly into the dry, hot pan. The cheese will begin to hiss and sing as it releases its natural fats. Leave it alone! Don’t poke it. Let it develop a deep, mahogany-brown crust for about 2–3 minutes per side.
- The Dressing: In a small bowl, whisk together your lemon juice, the minced garlic, the remaining olive oil, and your fresh parsley. This oil is the bridge that ties the salty cheese and the roasted greens together.
- Assembly: Arrange the warm zucchini on a platter, tuck the crispy halloumi in between the rounds, and spoon that bright, fragrant herb oil over everything while the cheese is still warm.
Nutritional Science & Benefits
This dish is a nutritional powerhouse for those looking to maintain steady energy levels:
- High-Quality Protein: Halloumi is a dense source of protein, which is essential for muscle repair and keeping you feeling full for longer periods.
- Healthy Fats: The inclusion of extra virgin olive oil provides monounsaturated fatty acids, which are fantastic for cardiovascular health.
- Zucchini Benefits: Zucchini is incredibly low in calories but rich in vitamins A and C, along with potassium, which helps balance sodium intake from the cheese.
- Digestive Support: Fresh garlic contains prebiotics, which feed the beneficial bacteria in your gut, while the lemon juice provides a touch of acidity that aids in digestion.

Meal Prep & Storage Guide
If you’re someone who likes to plan ahead, the roasted zucchini is your best friend. Roast a double batch on Sunday, and store them in an airtight container for up to three days. When you’re ready to eat, simply sear the halloumi fresh—it takes five minutes—and serve it over the cold or room-temperature zucchini. The contrast between the hot, salty cheese and the cool, earthy vegetable is actually a personal favorite of mine.
I don't recommend freezing this dish. Halloumi’s texture changes significantly when frozen and thawed, losing its characteristic "squeak." Stick to the fridge, and reheat the cheese in a pan rather than the microwave to keep that lovely, crusty exterior.
Flavor Variations
The Protein Boost
Add a handful of toasted chickpeas to the roasting tray with the zucchini for extra fiber and a nutty crunch.
The Mediterranean Twist
Toss in a handful of halved cherry tomatoes and Kalamata olives during the last 5 minutes of roasting the zucchini.
Low-Carb Sophistication
Swap the zucchini for roasted eggplant. The creamy, sponge-like texture of eggplant soaks up the lemon-herb oil beautifully.
Vegan Alternative
If you are avoiding dairy, look for a "grilling cheese" made from firm tofu or a specialty plant-based halloumi alternative. Rub the tofu with a little nutritional yeast and sea salt before searing to mimic the savory depth of the original.

Storage & Freezing Tips
- Refrigerator: Store in an airtight container for up to 3 days. Keep the components separate if possible to preserve texture.
- Reheating: Reheat gently in a skillet on medium-low heat with a splash of olive oil or butter.
- Freezing: Freezing is not recommended for this dish because ingredients like zucchini become soggy, rubbery, or mushy when defrosted.
Frequently Asked Questions
How do I prevent the halloumi from sticking to the pan?▼
Even if you have a non-stick pan, it helps to lightly coat the cheese slices in a tiny amount of olive oil before placing them in the pan. However, the most effective method is ensuring the pan is hot enough before the cheese hits the surface. If you put it in a cold pan, it will stick.
Can I eat halloumi raw?▼
Yes, you can eat it raw, but it has a very salty, rubbery texture. Cooking it transforms the cheese, softening the proteins and mellowing the salt, which is why searing is highly recommended.
What should I serve with this to make it a full meal?▼
If you need a bit more heft, serve this alongside a cup of fluffy, cooked quinoa or a slice of warm, whole-grain sourdough toasted with a little garlic. The grains act as a perfect base for the herb oil.
Is there too much sodium in this dish?▼
Halloumi is indeed a saltier cheese. To balance your overall intake, I suggest skipping additional salt on the zucchini—the cheese and the herb oil are flavorful enough on their own. Pairing it with a large side of greens or fibrous vegetables helps balance the impact.
