Step 1: Roast Garlic - Preheat your oven to 400°F (200°C). Take peeled garlic cloves and place them in a small baking dish with a drizzle of olive oil and a sprinkle of salt. Cover with foil and roast for about 20 minutes until golden brown and soft. Let cool, then smash into a paste.

Step 2: Prepare Bread - Slice the bread in half lengthwise and bake on a baking sheet for about 5 minutes until slightly crispy and golden.

Step 3: Make Garlic Butter Custard - In a mixing bowl, combine the roasted garlic paste with melted butter, egg, milk, salt, paprika, and parsley. Whisk until smooth.

Step 4: Coat Bread - Dip each half of the toasted bread into the garlic butter custard and spread evenly over the surface.

Step 5: Bake - Return the coated bread to the baking sheet and bake for 15–18 minutes until crispy and golden.

Step 6: Add Cheese - Top with mozzarella cheese and broil for 2–3 minutes until melted and bubbly.

Step 7: Serve - Allow to cool slightly before slicing and serving hot.
