Marinara is the classic—its acidity cuts the fat perfectly. But don’t sleep on ranch dressing, a Midwest-born deity of condiments. For a spicy twist, mix sriracha into mayo with a pinch of garlic powder.
The dip temperature matters, too. Cold sauce with hot cheese creates a glorious contrast. Serve your sauce in a small bowl, not a puddle. This is an appetizer, not a soup course.
