This is the ultimate Garlic Bread because there are three (yes, three!) sources of delicious garlic flavor - roasted garlic, raw garlic, and garlic powder! I guarantee that this will be your new favorite Garlic Bread recipe!
Slice the top quarter of the heads of garlic and place in aluminum foil. Drizzle with the olive oil and season with the ½ teaspoon of salt and ¼ teaspoon of pepper. Close the foil tightly around the garlic and bake in the oven at 325F for 1 hour. Remove the garlic and squeeze out the garlic cloves into a bowl and mash with a fork.
To the same bowl, add the butter, parsley, fresh garlic, garlic powder, remaining salt and pepper, and parmesan cheese. Mix thoroughly to combine.
Spread the butter mixture onto the inside of the 2 halves of the French loaf.
Increase the oven temperature to 350F. Place the bread on a sheet tray in the center of the oven and bake for 15 minutes until golden.
Notes
Short On Time? You can make a faster version in 15 minutes by skipping the roasted garlic (in step 1) and just increasing the amount of fresh garlic to 12 cloves in the garlic butter!
Use Unsalted Butter - This is so you can control the salt content to your preference. Alternatively, if you only have salted butter, skip the salt in the recipe.
Storage + Reheating - Store any leftover Garlic Bread in an airtight container in the refrigerator. Store any leftover garlic butter in an airtight container or wrapped tightly in saran wrap in the refrigerator for up to 2 weeks. Reheat until warmed through in a microwave or in an air fryer or oven 350F for 10 minutes or until warmed through.
Make Ahead - Garlic Bread is a fantastic 'make ahead' recipe! Follow the recipe as in and stop before baking (step 3) - wrap the loaves in plastic wrap, then in foil. Freeze until you are ready to bake. You can pop the frozen garlic bread halves directly into the oven and bake at 350F for 20-25 minutes until golden. If you need to make the butter ahead of time, you can keep it in the fridge for up to 1 week or in the freezer for up to 3 months.
