Preheat your oven to 200°C (390°F) and line a baking tray with parchment paper.
Prepare the garlic butter:
In a bowl, combine the softened butter, finely chopped garlic, chili (or jalapeño), and coriander. Mix everything together until well combined.
Add a pinch of salt (1 tsp) to season. Feel free to taste and adjust the seasoning to your liking.
Slice the Ciabatta:
Cut the ciabatta loaf in half lengthwise
Spread the garlic butter:
Generously spread the garlic butter mixture over the cut sides of the ciabatta, making sure to coat every corner evenly.
Add the cheese:
Layer the mozzarella and Red Leicester cheese over the buttered bread. Make sure you cover the garlic butter fully with the cheese.
Bake:
Place the bread halves (or slices) on the prepared baking tray and bake for 12-15 minutes, or until the bread is golden, crispy on the edges, and the cheese is beautifully melted.
Finish and serve:
Once baked, remove the bread from the oven and let it cool for a minute. If you like, sprinkle some extra fresh coriander over the top before serving for a burst of color and flavor.
