Halloumi-stuffed Mediterranean peppers are bell pepper halves filled with cubed halloumi, cherry tomatoes, olives, and garlic, then baked at 200 C / 390 F until the peppers turn soft and the cheese goes golden at the edges. The inside stays juicy from the tomatoes, and the halloumi holds its shape instead of melting into a puddle.
I make this when I want a vegetarian dinner that still feels substantial. The peppers do the work of a plate and a filling at once, so you don’t need much else besides a side salad or some bread.
The trick is roasting the peppers alone for 15 minutes first. That softens them before the halloumi goes in, so the cheese doesn’t dry out while the peppers catch up.
Halloumi is salty on its own, so I skip extra salt in the filling and just season with pepper and oregano. Taste the tomato mix before you fill the peppers, and add salt only if it needs it.
Why You’ll Love This Recipe
- Roasting peppers first keeps the filling from drying out
- Halloumi holds its shape instead of turning rubbery
- One dish covers your vegetable and protein at once
- Ready with pantry staples like olives and oregano
Ingredient Notes
- bell peppers: Choose firm peppers with flat bottoms so they sit level in the dish and hold their shape after two rounds in the oven.
- halloumi: Buy a block instead of pre-sliced halloumi so you can cut even 1 cm cubes that hold up during baking.
- cherry tomatoes: Regular diced tomato works as a swap, just drain off any extra liquid first so the filling doesn’t get watery.
- kalamata olives: Green olives work too, though they taste sharper and a bit more bitter than kalamata.
- red onion: White or yellow onion works fine here, with a milder flavor than red onion.
- dried oregano: Fresh oregano is a good swap, just use about double the amount since dried herbs are more concentrated.
Oven-Baked Halloumi-Stuffed Mediterranean Peppers
Ingredients
Method
- Heat the oven to 200 C / 390 F. Cut the bell peppers in half lengthwise and remove the seeds and white ribs.
- Arrange the pepper halves cut side up in a 9x13-inch (33x23 cm) baking dish. Drizzle with 1 tbsp olive oil and season with black pepper.
- Roast for 15 minutes, until the peppers start to soften but still hold their shape.
- While the peppers roast, mix the cherry tomatoes, olives, red onion, garlic, oregano, and remaining 2 tbsp olive oil in a mixing bowl.
- Remove the peppers from the oven and spoon the tomato mixture evenly into each half.
- Top each pepper with cubed halloumi, pressing the cubes gently into the filling.
- Return the dish to the oven and bake for 12 to 15 minutes, until the halloumi is soft in the center with golden edges and the peppers are tender when pierced with a knife.
- Remove from the oven and sprinkle with chopped parsley and lemon zest, if using.
- Let the peppers sit for 3 to 4 minutes before serving, so the filling settles.
Notes
- Roast peppers 15 minutes before filling, or the halloumi overcooks while peppers catch up.
- Skip extra salt in the filling since halloumi is already salty.
- Use thick-walled peppers so they hold their shape after two rounds in the oven.
- Cut halloumi into even 1 cm cubes for consistent texture.
Tips for Success
- Cut halloumi into 1 cm cubes so pieces cook through without turning tough at the edges.
- Roast the peppers alone for 15 minutes first, or the filling ends up cooked longer than the cheese needs.
- Choose peppers with flat bottoms so they sit level in the baking dish instead of tipping over.
- Taste the tomato filling before adding salt, since halloumi is already salty on its own.
- Line the baking dish with foil for easier cleanup, since melted cheese can stick as it bakes.
Variations
- Swap halloumi for feta if you want a softer, creamier filling that breaks apart instead of holding cubes.
- Add cooked quinoa or rice to the tomato mixture to bulk up the filling into a heartier meal.
- Stir in a pinch of chili flakes or smoked paprika for a warmer, spicier version of the filling.
Storage and Reheating
Store leftover stuffed peppers in an airtight container in the fridge for 3 to 4 days. The peppers will soften a bit more over time, but the filling still tastes good cold or warmed up.
To reheat, place the peppers in a baking dish, cover with foil, and warm in the oven at 180 C / 350 F for 10 to 12 minutes, until heated through. You can also microwave them for 1 to 2 minutes, though the halloumi will turn softer than fresh out of the oven.
I don’t recommend freezing this dish, since the peppers turn mushy and watery once thawed.
Serving Suggestions
Serve the peppers warm with crusty bread or warm pita for scooping up the tomato and olive filling. A simple green salad with lemon dressing works well alongside, since it balances the salty halloumi.
For a fuller meal, add a side of couscous or a scoop of rice. A spoon of plain yogurt on the side cools things down if the filling has a bit of chili in it.
These peppers also work at room temperature, so they’re good for a packed lunch or a casual lunch spread.
FAQ
Why did my halloumi turn rubbery instead of soft in the peppers?
Halloumi turns rubbery when it bakes too long or too hot after the peppers are already soft. Cut it into 1 cm cubes and add it only for the final 12 to 15 minutes of baking, once the peppers have already roasted 15 minutes on their own. Check at the 12-minute mark so it stays soft with golden edges.
Can I use feta instead of halloumi in these stuffed peppers?
Yes, feta works, though it crumbles instead of holding cubes like halloumi does. Scatter it over the filling for the last 10 minutes of baking so it softens without drying out. The dish will taste tangier and saltier, so skip any extra salt in the tomato mix.
Can I stuff the peppers ahead of time and bake them later?
You can chop the filling and cut the halloumi up to a day ahead, storing both in the fridge separately. Roast the peppers and assemble everything right before the final bake, since raw-stuffed peppers sitting too long can turn watery. This keeps the texture right when they come out of the oven.
What goes well with halloumi-stuffed Mediterranean peppers?
Crusty bread or warm pita works well for scooping up the tomato and olive filling. A simple green salad with lemon dressing balances the salty halloumi, and a side of couscous turns it into a fuller meal. I also like a spoon of plain yogurt on the side.
Are halloumi-stuffed Mediterranean peppers gluten-free?
Yes, this recipe is gluten-free as written, since peppers, halloumi, tomatoes, and olives don’t contain gluten. Just double check your olive brine doesn’t include gluten additives, which is rare but worth a quick label check. Serve with gluten-free bread on the side if you want something to scoop with.
How do I know when the peppers are done roasting?
The peppers are ready for their first roast once they start to soften but still hold their shape, usually after 15 minutes at 200 C / 390 F. They shouldn’t collapse or char at this stage, just soften enough to hold the filling. After the second bake with the halloumi, they’re done when a knife slides in easily.
