Preheat the oven to 375°F or 190°C.
Remove the crust from the bread and slice into cubes. Mix the salt and melted butter together. In a medium bowl, pour half of the butter onto the bread and toss. Repeat with remaining butter and transfer to a baking sheet.
Toast the croûtons for about 10 to 15 minutes or until golden brown. Toss occasionally. Once finished, add a little salt to the croûtons while they are still hot. Set aside to cool completely before using.
Note: For croûtons with a little more flavor, add garlic, fresh herbs or even chilies to the melted butter before pouring it over the croûtons.
