Preheat your oven to 450°F (232°C) for about 10 minutes.

In a mixing bowl, combine minced garlic, softened butter, olive oil, grated Parmigiano Reggiano, parsley, and kosher salt until smooth.

Slice the Italian or French bread in half lengthwise and place cut sides up on a baking sheet.

Spread the garlic butter mixture evenly over the cut sides of the bread.

Bake the bread in the preheated oven for 8 to 10 minutes until golden brown.

Remove from the oven and let cool slightly, then slice into 2-inch pieces and serve warm.
