Heat olive oil in a small saute pan over medium-high heat.

Peel and crush garlic, add to the warm oil.

Infuse garlic flavor into the oil, avoiding burning.

Turn off heat when garlic starts to sizzle.

Set garlic-infused oil aside.

Slice crusty bread into 1/4 - 1/2 inch slices.

Arrange bread slices on a baking sheet.

Brush bread slices with garlic-infused oil.

Combine parmesan cheese, cooked garlic, and rosemary leaves in a food processor.

Pulse until the mixture resembles coarse crumbs (cornmeal consistency).

Broil bread slices on low until lightly golden.

Remove from broiler and top with cheese mixture.

Avoid heaping cheese mixture to prevent a chewy center.

Return to broiler until cheese melts and bread is golden.

Cool on a rack.

Serve with your favorite dip.
