Halloumi and Roasted Grape Crostini is a warm appetizer that mixes salty pan-seared halloumi with sweet, blistered roasted grapes on crisp toasted bread. The halloumi turns golden and holds its shape, while the grapes go soft and jammy in the oven.
I make this when I want something that looks a bit special but takes under 40 minutes start to finish. It works for a holiday table or just a Friday night with wine.
The grapes roast at 200 C / 400 F until their skins split and the juice turns syrupy. That sweetness against the salty cheese and crisp bread is why this combo works so well.
One thing I learned the hard way: don’t skip drying the halloumi slices with a paper towel before searing. Wet cheese won’t brown, it’ll just steam in the pan.

Ingredient Notes
- baguette: Use a day-old baguette if you have one, it slices cleaner and toasts crisper.
- halloumi: Look for a block, not pre-sliced, so you control the thickness. Dry the slices well before searing so they brown instead of steam.
- red seedless grapes: Any seedless grape works, red or green. Green grapes are a touch more tart when roasted.
- honey: A mild honey works best so it doesn’t compete with the grapes. Maple syrup is a fine substitute.
- fresh thyme: Adds an earthy note to the grapes. Rosemary works too but use half the amount, it’s stronger.
- olive oil: Use a decent extra virgin olive oil since it goes straight onto the bread.
Golden Halloumi and Roasted Grape Crostini
Ingredients
Method
- Heat the oven to 200 C / 400 F. On a 33 x 23 cm / 13 x 9-inch sheet pan, toss the grapes with 1 tbsp olive oil and the thyme sprigs.
- Roast for 15 to 18 minutes, until the grape skins split and the juices turn syrupy. Set aside.
- While the grapes roast, brush both sides of the baguette slices with the remaining 2 tbsp olive oil.
- Arrange the bread on a second sheet pan and toast in the same oven for 5 to 6 minutes, flipping once, until the edges are golden and firm.
- Pat the halloumi slices dry with paper towels. This helps them brown instead of steaming in the pan.
- Heat a 10-inch nonstick skillet over medium-high heat. Add half the halloumi slices in a single layer, working in two batches so they don't touch.
- Sear for 2 to 3 minutes per side, until deep golden with a little crisp at the edges. Repeat with the second batch.
- Top each toasted baguette slice with a slice of warm halloumi.
- Spoon the roasted grapes and their juices over the halloumi.
- Drizzle with honey, add a crack of black pepper and a pinch of flaky salt. Scatter thyme leaves on top and serve right away.
Notes
- Dry halloumi slices well before searing, wet cheese won't brown.
- Roast grapes until skins split, don't rush this step.
- Assemble crostini right before serving, halloumi firms up as it cools.
- Use a rimmed sheet pan for the grapes, they release a lot of juice.
Tips for Success
- Pat the halloumi slices dry with a paper towel before searing so they brown instead of steaming in the pan.
- Roast the grapes on a rimmed sheet pan so the juices don’t drip onto the oven floor.
- Toast the baguette slices until the edges are firm, so they don’t turn soggy under the grapes.
- Slice halloumi about 1 cm thick, thinner slices dry out fast and thicker slices stay cool in the middle.
- Serve the crostini within 20 minutes of assembling, halloumi turns firm and rubbery once it cools completely.
Variations
- Swap the grapes for roasted figs when they’re in season, they roast in about the same time and get just as jammy.
- Add a smear of whipped ricotta under the halloumi for a creamier bite and extra protein.
- Use balsamic glaze instead of honey for a sharper, tangier finish on the crostini.
Storage and Reheating
Halloumi and Roasted Grape Crostini is best eaten right after you assemble it. Once halloumi cools, it turns firm and a little rubbery, and the toasted bread softens under the juicy grapes.
If you want to prep ahead, roast the grapes up to 2 days in advance and keep them in the fridge in a sealed container. Toast the bread a few hours ahead and keep it at room temperature in a paper bag so it stays crisp.
Sear the halloumi right before serving. It only takes a few minutes, and it’s the one part of this recipe that doesn’t hold up well once it sits.
Serving Suggestions
Halloumi and Roasted Grape Crostini works well as a starter before a light dinner, or as one of a few small bites on a party table. I like to set it out next to a bowl of olives and some cured meat for a simple spread.
For drinks, a dry rosé or a crisp white wine matches the sweet and salty flavors here. A light, dry lager works too if wine isn’t your thing.
If you want to turn this into more of a meal, add a green salad with a lemon dressing on the side to cut through the richness of the cheese.
FAQ
Why did my halloumi turn rubbery instead of golden?
Wet cheese or a pan that isn’t hot enough are the usual culprits. Pat the halloumi slices dry with paper towels before searing, and wait until the skillet is fully heated over medium-high heat. Sear for 2 to 3 minutes per side until a deep golden crust forms, that crust is what keeps the texture from going rubbery.
Can I use feta instead of halloumi in this crostini?
Not exactly, feta crumbles and melts when heated, while halloumi holds its shape because of its higher melting point. If you want to use feta, skip the searing step and crumble it cold over the warm roasted grapes instead. The texture turns softer, but the sweet and salty combo still works.
Can I roast the grapes ahead of time for this crostini?
Yes, roasted grapes keep well in the fridge for up to 2 days in a sealed container. Bring them to room temperature or warm them gently before spooning over the halloumi. Sear the halloumi fresh right before serving since it doesn’t hold up well once it cools.
What wine goes well with halloumi and roasted grape crostini?
A dry rosé or a crisp white like sauvignon blanc works well here. Both have enough acidity to balance the sweetness of the roasted grapes and the saltiness of the halloumi. A light, dry lager is a good option too if you’d rather skip wine.
Is halloumi and roasted grape crostini gluten free?
No, the toasted baguette makes this version contains-gluten. Swap in gluten-free bread or thick gluten-free crackers and the rest of the recipe stays the same, since the halloumi, grapes, and honey are naturally gluten free. Just check any packaged bread for cross-contamination if that matters to you.
What’s the difference between crostini and bruschetta?
Crostini uses thin baguette slices brushed with oil and toasted until crisp, which is what holds up under the juicy roasted grapes here. Bruschetta usually uses thicker, rustic bread rubbed with raw garlic and topped with something like fresh tomato. The thinner crostini base is why this stays crisp instead of soggy.
