Heat oven to 350° F.

Cut top of garlic head off and place cut-side down on pan; drizzle with 1 teaspoon olive oil. Bake 20-30 minutes, or until garlic is soft. Once cool, squeeze garlic from each clove.

In large skillet over medium-high heat, cook onion in 1 tablespoon olive oil. Stir onion frequently until slices begin to brown. Reduce heat to low and continue cooking until onions are soft and reach medium brown color.
