Preheat the oven to 375°F.

Line a baking sheet with aluminum foil. Arrange the bread halves cut-side up on the sheet.

Place the softened butter, olive oil, and garlic in a medium bowl. Stir until thoroughly mixed.

Spread the butter mixture evenly over the bread halves.

Bake the garlic bread on middle rack of oven, rotating the pan halfway through the cook time, until the bread is light golden brown at the edges, 12-18 minutes.

Check to see that bread is done. Remove from oven or add time as needed.

Cut the bread into 2- to 3-inch slices and serve.
