Italian sausage, mozzarella, and garlic butter baked into pull-apart perfection.
Use hot Italian sausage for more flavor and heat. The toasting step is critical to prevent soggy bread. Don't hollow out the buns too much or they'll collapse. Raw sausage must reach 160°F for food safety. Fresh herb topping adds brightness that balances the rich meat and cheese. You can prep the buns ahead but assemble and grill right before serving.
