Here is a recipe I learned from the Cajun Chef.

One french loaf
quarter cup butter
pinch salt
3-4 cloves garlic

Preheat your oven to 375 degrees F. Chop the garlic very fine. I prefer this to using a garlic press, since that tends to bruise the garlic. Soften the butter  and stir in the garlic and salt. Spread the newly made garlic butter over the french bread, which you have cut in half. Place in the heated oven for about ten minutes, or until the top is slightly browned.

You can alter the amount of garlic to butter as you prefer of couse, and sprinkling some grated parmesan over the whole deal never hurts either.
