Preheat your oven to 180°C (300°F).
Slice the baguette into ¾-inch thick pieces.
In a bowl, mix softened butter, minced garlic, and salt (if needed).
Spread the garlic butter evenly on one side of each bread slice.
Top generously with grated cheese and sprinkle chili flakes.
Place the slices directly on oven racks or a baking tray.
Bake for 5–6 minutes until the cheese melts and edges turn crispy
