You can peel individual garlic cloves and completely submerge them in oil in a glass jar or plastic container. Tightly seal the jar or container with a lid and place directly into the freezer. Use a spoon to scoop out the garlic as needed. Alternatively, you can make a puree of garlic and olive oil by mixing one part peeled garlic cloves with two parts olive oil in a blender or food processor. Transfer the puree to a freezer-safe container with a tight-fitting lid and place in the freezer. This method is very convenient for cooks, as the oil prevents the puree from freezing so it can be scooped out and placed directly on a pan.
