Easy peasy. Do it once and you're a pro. If you want to get fancy, throw some parmesan cheese on top before you broil it.
1 loaf of french bread (or any artisan bread)
1/2 c butter, softened to room temperature
2 garlic cloves, minced. (or just use garlic powder if that's all you have on hand)
Preheat oven to 350 degrees. Slice loaf of bread in half. Set aside. Mix butter and garlic together in a small bowl. Spread butter mixture on bread. Bake in oven for 10 minutes. Turn oven to broil and cook for 1-2 minutes more.
