The Legendary 4-Ingredient Hot Onion Dip That Disappears Every Time
There are recipes that get passed around, and then there are recipes that become part of a family’s identity. This bubbling, golden, impossibly cheesy hot onion dip is firmly in the second category. It has graced potluck tables, church suppers, holiday gatherings, and backyard cookouts for decades — and every single time, the dish comes back empty. No leftovers. No stragglers. Just a scraped-clean bowl and a crowd asking who made it.
The beauty of this dip is almost offensive in its simplicity. Just four humble ingredients come together in the oven and transform into something that pulls into long, molten strings of cheese with every scoop. Serve it alongside buttery crackers, toasted baguette slices, or sturdy chips, and watch it vanish in minutes. Here’s the recipe that’s been earning legendary status at community tables for over forty years.
Ingredients
- 1 cup mayonnaise (full-fat works best for richness)
- 1 cup sour cream
- 1 envelope (about 1 oz) dry onion soup mix
- 2 cups shredded mozzarella cheese (or a blend of mozzarella and Swiss)
