In a small bowl, mix the pressed garlic with the softened butter, olive oil, grated Parmesan, parsley, and kosher salt until smooth.
Cut the bread in half lengthwise and spread each cut side with the garlic butter. Place the two piece on a baking sheet or directly on an oven rack, cut side up, and bake until toasted, about 8-10 minutes. Remove from the oven and cut into 2-inch pieces, and serve warm.
Notes
The butter mixture can be made ahead and refrigerated for up to 2 months. Bring the butter to room temperature before spreading on the bread.If you're not a fan of parsley, feel free to use fresh basil or oregano, rosemary, or an Italian seasoning blend.
